Nah. This kind of crap keeps people employed. Job security. Doesn't mean it wasn't a dumb idea. Every vehicle manufacturer has done this at least once.
My wife's stepdad works at a Ferd dealershit since the 1980's he's about to take his retirement. He had some years left but he explicitly said it was because he couldn't care less for the new training and the "Audi" build style 😂
As a Ford tech for a little over 2 years, this is the 6th time I've personally seen this happen, not including the rest of my shop. What we hear is either 1. The tensioner itself fails and there is no longer any oil pressure, or 2. The timing belt loses every single tooth (likely still tensioner failure) and becomes smooth and of course, no oil pressure. Most cars will keep driving like this until the "Low Oil Pressure" warning crops up, at which point we get it. There is no recall, but ford issued a TSB which directs to replace the long block and turbo. Which is why they are in such high demand. Obviously just a horrible engine design. Absolutely loved watching this one. I also hate that turbo vacuum line, and there's always one fuel injector connector that gives me hell. Great teardown!!
@@shadowopsairman1583 the only one I almost never have issues with is the 1st gen 3.5, even with half-assed maintenance. I've owned 2 and worked on many. But all the small ones are a pain to work on and have numerous issues. Both 1.5's especially. So yes, I'm inclined to agree.
ive replaced 2 1.0l ecotrashes so far. first one belt failed and lost compression and the second one they drove it in at 0 psi of oil pressure and surprisingly it still ran great
Ford needs to have a new car called the Ford Triple Threat -- it uses the wet belt system, the Power Sh*t tranny, and the old Pinto's "built-in-BBQ" rear gas tank
I remember when Ford introduced this engine. Part of the marketing included demonstrating how just the block, or the block with head on it could fit in a suitcase. Seems that was intentional not to show how compact it was, but a new mode for transporting replacement engines to dealers.
europeans are convinced this exact engine is one of the BEST bc europeans are used to even worse garbage from VW (VW engines that were never offered in america) LOL
All the engineers who worked on this cried when they were told it had to have no timing keys and that they couldn't afford either a timing chain or seals for the belt. Only the accountants went home happy that night. Still.... There was this one engineer, maybe a team, who stood their ground. They may have risked it all. Their careers....everything. I salute the head bolt team. That was unexpectedly satisfying
Loads of modern engines do not use keys. It gives more accurate timing. If the bolt comes loose, the key won't save you, anyway. However, keyways aside, an engine does need to be designed competently and we see a few howlers, here.
@@camshaftcasting1451 just because loads of manufacturers don't use them doesn't mean its not a shit idea. It's designed to make them hard to work on so they go back to the dealers, ideally to the tip when the engine shits, don't pretend its for more precise timing, what a crock lol.
As a Ford Mechanic from Germany I service the 1.0 Ecoboost alot. First of all the 1.0 is extremly sensitive, service it well and don´t mistread it and it will run for a good while, but make one mistake, ( run without water/ put in the wrong oil/ abuse it when cold...) it will die on you garanteed. I have seen allot of Timingbelts and Oilpumpbelts like that because someone put the wrong engien oil in wich then started to degrade the Belts. Takes only a few weeks for this to happen with the wrong type of Oil. Also the Cranksshaft isn´t keyed so the belt can balance itself when you tension the new Timingbelt, because you need to lock the VVT units and the camshafts when changing the belt. That also means you need to take out the starter motor and put a Flywheel lock in so the Crankshaft can´t turn when you change the Belt. The New 1.0 Ecoboost now has a Timingchain, but for some UNBELIVABLY STUPID REASON (mostlikly money). The Oilpump is still Beltdriven. So you still need to tear the engine all 10 years or 200000KM/125000miles apart just to change one small belt. Facepalm!! Also the waterpump is now Driven by a Dry theeted Belt wich is Driven by the Camshaft end by Cylinder 3. YAY. Pls end me know.😥
I understand that on this engine there is no key way for the oil pump drive (a seperate belt to the crank belt) The oil pump though needs no timing like crank!!
This engine was designed to survive just long enough for the car to be out of warranty. Also, Ford hasn't keyed their timing components in at least a decade. It's all held in time via tension. They even make special tools to lock everything in place anytime you need to undo the crank pulley. Because that bolt is the only thing keeping the engine timed.
wait 'til you get one of those shitty Peugeot 3-cyl ones. they destroy themselves way before the warranty is over and Peugeot always try to put the blame on you... 😹
The older Mazda L engines(MZR 4 cylinders) also didn't have keyed cranks. This channel has 3 teardown videos for the turbocharged 2.3 engines and Eric wasn't happy any time he had to touch one. Mazda's own Skyactiv engines have changed the crank to have keys, but some of the Ford Ecoboost 4-cylinder engines are based on/have design influences from Mazda L engines, so they still lack crank keys.
I'm not an automotive design engineer. But I have worked on several models of older American engines. V-8s of course. Is there any other kind? OK. Straight 6s can be great. The lack of keyed belts still stuns me. Am I correct that the tensioner made of plastic, that had disintegrated, was all that kept the engine timed? Unbelievable. It must be a non-interference engine because there was no evidence of valve damage? American Ford V-8s could be be poorly designed. A 289 1966 Mustang used a cam gear with nylon coated teeth. The nylon would wear down and cause the incredibly strong metal timing belt to slip a tooth or two. Hopefully no more than that. Why? It made the engine quieter. And probably accelerated planned obsolescence for Ford.
I followed a ford puma the other day and one of the exhaust pipes was still shiny inside.... They've welded a second pipe by the side of the real pipe to make a fake twin pipe exhaust to make it look like a powerful car. I've also seen 3 new ish pumas with rusty non functioning back brakes.... Dopey owner driving around for 3 years in a new car with only front brakes... 🤮
As an ex warranty administrator for Ford here in the uk I can say we changed dozens of these engines under warranty. We were doing several a week! It’s a completely poorly designed engine with little robustness. We had them meticulously maintained and still failed. Ford technical told me they were stressed to the limit the minute they leave the production line and have no resistance to any faults like low coolant. In the end we didn’t even bother stripping them down. Just fit new ones. Must have cost Ford millions in warranty repairs. Same as the 2.0 litre eco blue diesel in the Transits. They have tarnished the Transits reputation.
Very surprised Ford allowed this design to go into production!! This wet belt type must have limited life - with such destruction by the belt through the oil pick up etc When the engine was stripped!! (Even the tensioners were damaged too)
I had the misfortune to own a Focus, worst car I’ve ever owned, every thing that could go wrong Did. I will never buy another Ford Ever Again, that’s I’ve now found out how good Vauxhall cars Are !
Recent MSN story: "According to the recall notice, the belt tensioner arm may fracture because the retention caulk joint isn’t robust enough to withstand engine vibrations. If this happens, the tensioner could separate from the backing plate and cause the belt to degrade by losing teeth."
pfft, its built Ford tough. it'll easily outlast every other brand on the road. which is easy to do when Ford's spend more time dead on the road or in the shop somewhere
I'm nowhere near an expert on engines, but I have had a couple apart, and of course I watch this channel. This is the first time I've ever even *heard* of a wet belt.
@@TheRealColBosch The actual engines from Stellantis Group (1.2 Puretech 100/130/155 Hp engines) equiping Peugeot/Citroen/Fiat/Opel cars, are all wet belt engines. If you change oil as required by manufacturer, with required specs oil, there should be no problem.
this has got to be one of the funniest teardowns on the channel, because I see these engines a lot as a technician and they always sound like they're close to dying. Ford never fails to impress me with their engineering silliness
I think that Ford labels that car as “Eco” because it is cheap for them to build. That’s it. Never intended to be cheap for the customer or in fuel. Great video, as always, Eric.
I've seen redundant systems before, but never redundant failure modes. If that oil pump belt didn't get the job done, that timing belt was ready to let go at any minute and finish the engine off
My wife's ecoboost Focus engine split a coolant pipe(plastic) and dumped its coolant in a few seconds, overheated in under a minute and conked. A Ford replacement was 1400 pounds sterling, and with a new clutch and flywheel fitted our bank account was minus 3600 pounds sterling. This was a 15000 pounds sterling car that had only covered 75000 miles. We still have the car and it is now on 108000 miles. Our daughter is having it as her first car and hopefully squeeze another few thousand miles from it. Thanks for the engine breakdown vid, I hope they have sorted thise daft belt probs out. Duplex chain drives would have been much better, after all, it us a motorcycle engine😄
They are very eco friendly because they're always catastrophically broken so they're never running 😂 We had one that shut off on the customer, it would crank but not start. Pressure tested the cooling system and cylinder 2 filled up the spark plug tube in about 2 seconds. Engine overheated so badly you could feel the warped spot between the block and water jacket lol.
The engineers really worked their asses off to make these as cheap and quick as possible to assemble. Which is good, because they'll be replacing a lot of them
I don't know about "asses off" that'd mean the thing would actually also be durable and fuel efficient. Seems like a slap n dash job ruined by pencil pushers (accountants) and hand waving educated idiots (marketing). As always. Sincerely, an automotive engineering student.
Hi, "I Do Cars" -thank you so much for this video. Long story short, I've owned a 2014 Ford Fiesta 1.0L since day 1. today in 2024... that thing is running like new. of course, I can feel the plastics shaking and vibration from wear... but the engine, I have nothing to say about it. My oil changes have been ON TIME. Maintenance is key, changed the spark plugs at 100,000 Mi, same with the Coolant and the belts (all). I had to replace the water pump and that's it.. I am very happy with this little engine.. It does gives a 45MPG on highway... and about 38.5 combined. Stilll.. yes still after 10 years and 140,000Mi... Thank you for this video, I will be happy to do more on my little engine to last longer... Cheers!
You even had the pre coolant system fix year. I have a 2016 with 130k, oil changes, plugs, air filters, and it’s doing great. I did replace my suspension components after driving a few too many Uber rides with passengers pushing me well beyond the payload capacity of the little car. Probably will buy a used replacement engine so I have one on the stand ready to go with a new timing belt, and when the used engine hits timing belt time swap them around. Here’s to hoping our little Foxes keep running strong.
I have 2013 fiesta 1.0 ecoboost with 150.000 on it and it still runs fine .i did have to replace the dps6 transmission this week because it was more a noise complaint for a few months because it may have a few busted bearings the fault is mine i never changed the oil but it only cost me 2400€ for a refurbished one and built in and that transmission is working fine
I think it'd be interesting to see you do a tear down with an engineer that helped design the engine. If they are no longer employed by the manufacturer then hopefully they could give honest answers about the design decisions they made and the constraints that were placed on them.
This engine is also used in the Fiesta, in 100, 125 & 140 hp. Despite being calld 'eco', the fuel consumption was only slightly better than the previous normally aspirated 1.4. The 1.4 was just an adequate engine, burnt a bit of oil, but will probably outlast all the ecoboosts. Here in Europe, no keyway is becoming more common. Like you, I think the main reason is cost, but the excuse given is that the timing is set using holding tools, then the bolt tightened, so the timing is more accurate than being fixed by a keyway. My brother left a breaker bar on his crank pulley (Peugeot 307 2.0 petrol), hit the starter, bar hit the chassis, undid the crank bolt, timing moved, valves bent. Oops!
I'm baffled by why this engine and car exist with such terrible fuel economy. The Toyota 5S-FE (2.2L I4) in the XV20 Camry was a basic NA engine with an ancient 4-speed (3+1) auto was rated 21/27mpg on the EPA cycle. Admittedly that standard has been updated but I personally saw 29-30mpg on long highway trips with the AC running. The Ecosport is about 300 pounds heavier and has more emissions criteria to meet but...how can it be 25 years newer and still be this bad?
@@aaronvienot Ford EcoSport uses a more reliable torque converter automatic transmission, not a DCT (Dual Clutch Transmission), which effects fuel mileage.
No keyway is madness for the timing-critical parts. Hell, even way back in the 70's and before, they used keyways to make sure things could not get out of basic alignment. There were always ways to tweak the timing in other ways back then.
I had a 2014 Fiesta with the 1.0T. Started exhibiting head gasket failure symptoms (cold start misfire, no heat due to air in cooling system) around 40K miles on it. Ford put a new engine in it under warranty and I sold it not long afterward. Having seen this teardown, I’m glad I did. Their paperwork said “cracked block” - assume they meant cracked head. It was amazing on fuel, torquey, and sounded neat - neat enough to get my car/youtube video featured in a Jalopnik article on “cars that sound better than they ought to.”
No, they do mean cracked block! They cut a channel between the cylinders and that apparently cracks, giving the symptoms of a head failure whereas you really need a short block to fix the engine. Or a complete swap of everything.
Regarding fuel economy, EPA rates 1.0T Focus worse on fuel compared to, say, a Mazda3 Skyactiv 2.0 from the same era while making LESS power. EcoSport was also rated worse on fuel than Mazda CX-3 or Honda HR-V, both with larger NA engines that make more or similar horsepower. Given the lack of displacement tax in North America and the issue with Ford Powershift, I'd love to know the reasoning of anyone who bought the car. This is why I am glad North America doesn't have displacement tax because then you get terrible engines like this. In a Fiesta or Fiat 500 I think it's fine, but in a Focus or EcoSport, the displacement is just too low and so you have to constantly rely on boost, which destroys fuel economy(engine has to run extra rich to prevent knock) and engine longevity. If you have to have a tax, base it on fuel consumption or emissions, not displacement.
If a turbo engine is not on boost it is inefficient equalling WORSE fuel economy due to lower compression to allow for the increased cranking pressure of the extra air blown in due to the turbo.
@@gvicj05 I'd say it's a bit more complicated. My Subaru on boost was thirsty, keeping it off was more efficient but less fun. My direct injection 330i was very efficient, unbelievably efficient. So much so that my 1.5l Ecoboost couldn't match it and you needed it in boost all the time because there was no power without it, and would leave you limping out of junctions dangerously. My current 320i does have turbos and you can hardly tell it's a boosted engine, and is even more efficient due to the direct injection. I'd say direct injection is the key to an efficient engine, turbo or not.
@@johnsim3722e said that an engine with a turbo not in boost will be less fuel efficient than that same engine without a turbo, which is true due to parasitic drag.
And they got a wards best top 10 engine award ! They claimed to the public including mr Ford what a great design it was for the post recession years, they stuck it in multiple vehicles. They deserved the lawsuits all of them. Although they have other better products I often wonder how they let this junk get approved! Sad very sad to save a buck
I hate that auto manufacturers constantly ignore if it isn't broke don't fix it. So many car companies take designs that worked perfectly fine and then make it worse.
On the negative side, the oil-soaked belts mean the engine will fail relatively quickly. On the plus side it'll still outlast the two PowerShift automatic transmissions it'll be connected to 🤣
Actually... you'd be surprised. My aunt and uncle had (or maybe still have) an EcoSport and the engine was nothing but trouble from day one. It was taken care of but seemed to chew up a belt like this one did every 20k miles. I think it spent more time in the shop than it did their possession, but the transmission never went out. I hit the transmission lottery with my 2013 Fiesta.... for a while, at least. It went in for the recalls, and every once in a while it would shudder, but the TCM going out at 132k did it in back in 2021. After six months of waiting I bought a new car, and here we are almost two years later and it's still sitting on the lot, not fixed. A shame, because other than the TCM I never had an issue with the car at all. Ran great, got amazing gas mileage, and the only time it left me stranded were dry rotted tires from sitting before they went on my car. Wasn't obvious at the time of purchase, unfortunately.
This engine has an appalling reputation in the UK. It is known in the motor trade as the Ecoboom because it blows up so frequently! Wet belt failure blocking the strainer and causing low oil pressure and subsequent bearing damage…pretty much exactly what you had there.
Just so simply not correct for over 10 years was the best selling car in the UK most of the doubling the amount of registrations the the car that came in 2nd place so yes will seem like high failure rate but if driven well and serviced great fun engines in 2014 the fiesta had a 1.0 140ps I drove one for 6 months averaging 46 mpg and a run to Leeds from London I was getting 60mpg.
How does it run long enough while missing so many timing belt teeth to nuke the bearings? If would expect valve contact or just so out of time it won't run before all that bearing damage
@@rossmills7218 McDonalds is one of the most popular restaurants in the world... doesn't mean it's any good. Ditto the Ford Fiesta. Though to be fair the Poms are used to rubbish cars, they bought all that BMC/BL/Rover shite for decades lol
Very common issue around here in Brazil, using The wrong oil specification causes that problems on the belt material, it deteriorates and get loose in the oil, Ford Ka, GMC onix are other examples. Very good vídeos Eric!!
I also was thinking that the wrong and oil would be detrimental to the belts. The problem is that all the heat and contaminants can be good for rubbers.
I doubt any engineer said that. More likely an actuary and executives in a boardroom demanding cost cutting design options. "Do it or you're fired" is a very convincing argument. It's not just Boeing building crap to increase short term stock price.
@@IslandArt61 the car (or any other produt) only hs to last the warranty period) then it isn't manuf's problem. No point in building cars that last 20yrs for munuf's
I worked for Ford as a mechatronics engineer in Germany... The Eco boost has been around since 2010 in European fords. And what can I say, at that time Ford could no longer provide replacement engines under warranty, we had cars that had to wait for new engines for over a year... Built to just survive the lease, if I had to guess?
there are so many little fiesta running around in the UK with I'm assuming the same engine. I have a feeling that it comes down to the usage scenario rather than the actual engine. Such as short drives, low miles, low miles but long wait until oil changes. Low miles, short distance driving and long time until oil service is what I believe kils engines nowadays.
can you imagen wait for 1 yr... yet if you are fail to make a paiment, you get all kind of fees and penalty fees. sucks how big corp get away with their BS.
@@noahcotney2957gm is literally garbage. Their DOD failures and piss poor transmissions are a joke. Any of their smaller engines are also junk. The l5p is good but damn, I see so many of their gas v8s and transmissions replaced.
I love when you tear down engines like this...smaller displacement units that us average Joe's might have out in the driveway. If you're taking requests I wouldn't mind seeing a 1.4L Fiat Multi-Air teardown so we can see the funky electro-hydraulic intake valves...
You don't see a lot, it's a whole module that goes on top of the head. Not a lot to tear apart. Good system providing you keep the oil fresh and use exact specs for it. Oh, and on the 1.4l if you replace regularly the small bolt-with-filter on the side of the head.
Thank you for showing me what happened to my ford focus ecoboost 50,000 miles, serviced by ford at the correct times and it still went wrong and ford don't care. 30 years driving ford, but never again!
You were unlucky, the belts usually shred at 70,000 miles with the teeth going into the oil pump so the crank bearings fail. These engines are well know for this if you are a car repairer
45 mpg on the highway is pretty damn poor for a 1.0 litre engine in small car. My Skoda Octavia 1.4 TSI will easily return 55 mpg in highway driving. My wife’s Suzuki Swift with the 1.0 Boosterjet engine averages 50 mpg with mainly short journeys.
@@davelowets For sure it is, you could easy make a better design on the oilpump/balance chaft if there was no cost issue. Even using buckets on the head is a clear sign. you don't use buckets on car engines, well you could if you are going past 8000prm appication, but I don't think a eco motor have that's for a goal.
Its actually bad even for cost cutting. To cut costs, they would have made a better engine by NOT having a fuel pump attached to the cam. And the chain design is the worst I've seen for , well ever. They could have used a single double link design and a crankshaft oil pump.
While I agree that is a cheap, poorly designed, POS engine, I have to say it had the coolest sounding head bolts when loosened that I've heard on the channel. Thanks for sharing, Eric!
I had a 2016 Fiesta with this motor It was smooth, sounded great, had nice mid range punch and got 52mpg highway. Definitely made an economy car more interesting to drive. I also dumped it when the warranty expired because I knew it was a ticking time bomb as evidenced here.
@@obsoleteopticsa little. they are notorious for their unreliability. If it's what ya got then run with it while it works but dont expect any more than like 100k tops.
@@obsoleteoptics I'm convinced that the engine in this video had 50,000 miles and failed as written on the oil filter. I recommend you get that belt changed out for piece of mind.
When the IDC guy said "Mechanically regapped", I knew I was watching the right channel. One of many good ones during this educational AND enjoyable video.
I'd like to say I was surprised with how bad the engineering and design of this engine was, but Ford has a long and sordid history of making subpar engines. Love the teardown and commentary!
Shockingly GM has a wet belt in at least one of their new diesel engines, I think powering the oil pump, and you have to pull the engine or trans to get to it. Imagine spending the diesel tax, and having this junk in your engine. Sadly it's probably going to be a trend to keep cars from being too reliable and keep them failing so you have to replace it with a "cleaner" new vehicle.
The 5.0 Coyote is probably the best modern engine they have. The old 5.0/302 from back in the day bc was a good one also. The problem with Ford now is “planned obsolescence”. They don’t care if you want to keep a vehicle long term. They quit product support as soon as they are legally able too.
@@OUSWKRYeah but that's their one thing. Funny enough I feel like nearly every generation of mustang has a fairly bulletproof motor.. but most of their other cars go to shit. It's like they're obsessed with the Mustang only lol
I sold my 2015 1.0 ecoboost when i found timing belt chunks when i changed the oil at 85k miles. Feeling pretty good about that choice. Replaced with a 1st gen mazda3 2.0 that has been rock solid.
I think if you had gone for a Skyactiv 2.0L then it would have been two excellent choices but I think you made an excellent choice and a pretty good one
@@big0bad0brad i saw some videos about gen1 underbody getting quite rusty, not sure about early gen2 like mine, we don't get snow at all in my country but it might still be a problem.
I’m surprised that crank bolt came out so easily, that is a torque to yield bolt to 360 deg. I’ve replaced several of these engines and they all look just like this one or worse. It takes a special tool to remove and install the crank bolt. Great video
Hi Eric, great teardown, I've been curious as to the insides of the 1.0 Ecoboost and it's wet belt! I was one of the first to buy one in North America: I ordered a new 2015 Focus, 6-speed manual, a couple of months before that engine was added to the Focus plant in Michigan, based on the good reviews the engine was getting in Europe (this was in 2014, before the problems became known). I drove it daily here in Canada, summer and winter, and put 330,000km (a little over 200,000 miles) on it WITHOUT changing the timing belt or touching the engine in any way, other than regular oil changes and a set of spark plugs! I guess I was really lucky....I sold it in late 2021, as I was having some transmission issues...and by that time it was apparent that the belts were a ticking time bomb. I was getting rather nervous about the belt failing, and having read up on the belt replacement procedure (special tools required to align everything because of the unkeyed shafts) I decided to let her go. It served me well, although the fuel economy was good but not as great as I had hoped. I think the reason it lasted as long as it did was the fact I was driving highway, 77 miles to and from work, each way. I did run the heck out of it, though, you could rev those things up pretty high! I always said it wouldn't win a race, but it wouldn't get in anyone's way either. I think what really kills the belts (other than having a belt run in hot oil in the first place) is city driving, the 240 degree power pulses of a 3-cylinder at low revs must put a lot of stretch-and-release tension on them, no wonder the teeth shear off! I miss the ease of service of my 1993 Escort from years ago, I could change the timing belt in 45 minutes in my driveway...no such cars nowadays. :-) Keep up the great work!
I currently have a 60k 2018 Fiesta with that Ecoboost engine and honestly I've found it's okay compared to various other engines I've experienced. You may find it hilariously small but in Europe it's a more "sensible" size. I would suggest that the overall failure of that engine you have there is belt degradation which secondarily blocked the oil pickup for a lack of oil pressure. This is a known thing here, you have to religiously use the correct oil for that belt, a Castrol/Ford recipe based on 5W20 and nothing else. If the oil pressure light comes on, you stop and call for a tow, do not attempt to drive home. Thanks for doing a ecoboost!
My 2.2L GM Vauxhall Vectra was literally priced off the road for being a Gas Guzzler. I replaced it with a 1.4 litre Golf that does 50MPG so the annual road tax is less than 1/3rd of a tank of fuel. Of course old Tesla Model S drivers will have the last laugh paying no tax at all.
I have an 18 Focus with one of these engines. Typically see 44-48 MPG on it with the 6 speed manual. From all I've heard and seen, the first few years had bad rubber/plastic for the cooling system externally leading to more overheating issues, but all years share those little coolant passages between the cylinders. Later 1.5L 3cyl ecoboost have a small passage drilled a bit deeper so coolant isn't touching the head gasket. Additionally, the belts are meant to be maintenance items at 150k miles, though I'm not sure how realistic that is with 7.5k mile oil change intervals, so I change mine every 4-5k. Every time I have seen this failure, the same symptoms happen, making it hard to know the cause, but effectively the oil pump locks up and sheers the teeth off the belt. Given both belts have continuous oiling from the oil pan by being dipped in, it seems like junk gets in the oil pickup and stops the flow. Whether that is sludge from long intervals or bits of the belt cracking off as gas and carbon get into the oil is hard to say and know as it kinda all looks the same when it is small. The belt is materially designed to not decay from being in oil, but I don't know what amounts of gas might do to it. That said, I think the most important thing is checking oil level (should be cooler oil then) and condition. I saw plenty of Equinox have stretched timing chains and is was anywhere from 60-120k miles, a shorter interval than these belts for replacement (while timing belts for GM were 100k and chains started becoming 150k on the newer Colorado's timing chain). Though I figured you'd have to take the head off to get these belts off... there goes my idea of an almost engine rebuild and check at 150k miles. I was hoping it would be like the GM V-8 with AFM where you see almost no head gasket failures in them... because you see lifter issues and the head gaskets are replaced when you do lifters. In my ~4 years at GM I saw a LS head gasket failing once, but lifters hundreds of times. Was ~$3.5k if it was just lifters, $5.5k if the cam was bad and ~8k for a new engine installed. I'm interested to see how my 1.0 does compared to my 302.
My 2012 Focus 1.0 ecoboost is on 77k I’ve had it 4 years and apart from a fuel leak and a battery that died it’s hasn’t missed a beat. I don’t know how your epa fuel rating works but I have recently getting 47.2 mpg

It is bigger, more refined and doesn't sound like its misfiring unlike a 3 pot yet its still able to return more than 50mpg. Best part of all its chain driven rather than belt driven mean it won't have a costly £1000 bill for belt replacements.
@@gravemind6536 i agree I think the wet belt over a chain is stupid considering how many hours labour it takes to change it. Ironically the 2006 Focus that it replaced was a chain driven engine and I traded that off with 140k on the clock I’d say the mk2 Focus was a much better built car as this mk3 has had silly little things needing to be done and it’s only on half the mileage
Here in Brazil, we've been dealing with those three cylinders engines, wich push the Ford Ka vehicle since 2014. We've regularly been dealing with that timing belt failure you've faced, when the timing belt loses its teeth. It's been caused when owners use not specified oil for a long time and timing belt starts to lose teeth or releasing material, wich block the oil pump. That engine has another serious problem I've faced so many times: in some cases, the engine is running with no oil or with low oil pressure and there's no oil indicator blinking. When you finally realizes the engine has lubrication problem, the engine is destroyed. 🤦🏾🤦🏾
Long story short, you have a bunch of car owners not following guidelines, neglecting their cars. Then when they break, they say "you should have bought a Toyota".
@@bmw803 To be fair having a wet belt is just asking for failures nobody expects. Timing belts will eventually fail and with this system they will send pieces into your oil.
@@Alobster1 That I ain't gonna argue. It's definitely STUPID. Put a chain and forget it. They want to save on a chain vs belt, but spend how much more replacing engines when they fail.
Great video! When this engine first came out, I was fascinated by it. Here in the UK, Focus, EcoSport, Fiesta, Mondeo, they all had this engine. And it is known as EcoBOOM. Because there are 3 recognised ways it can implode. Ford will only replace, for one of these faults. They would know, all 3, from bench testing 😳
@@MrWilliam.Stewart One's the timing belt, the other is a coolant pipe that's prone to cracking and dumping all your coolant, and I believe third is a miniscule cooling channel between cylinders that's prone to clogging and blowing the head gasket. I'm so glad I went with the I4 Duratec Ti VCT in my Fiesta.
Great teardown as always! Thank you! I don't know if anyone already mentioned this little fun fact: this engine was voted "International Engine Of The Year" (in its category) many times.
Once you attach it to a turbo it’s guaranteed to be a worst design. Cooks the oil the longer it runs. I wonder whether they slap one on to make sure the engine doesn’t last. As long as it has overdrive I’ve seen V8’s get nearly the same mileage on the highway and they don’t have as many problems with reliability.
It's a shame, they could've made this engine so much better with little changes to it's design, and it'd probably be quite reliable, but the way they did it is just crazy.
It's exactly as designed, a cheap car engine that's expendable right after warranty so you'll be in market for a new car. First time with Capitalism I presume?
The only car you would want to swap IN a rotary engine.🤣🤣🤣 you could break it down, replace the seals and put it back together in the time it took to look at that ecoblah!
I absolutely love this 999cc ecoboost motor, my 2016 fiesta sedan averages 52mpg with a best tank of 56mpg. It was dubbed the sfe (super fuel economy) and was an option with a 5 speed manual in the 2016-2018 fiestas in the US. Ford hugely under rated the fuel economy of these motors. Mine is listed as 31 city, 43 highway, 36 combined. And it actually gets 40-50% better economy combined. Highway only at 60mph the economy sits in the 65-70mpg range. I bought the car used dirt cheap and has been amazing as a daily driver. The only issue ive had so far is a leaking coolant tank that cracked at the outlet barb, got a new one for $35. I do plan to replace belt, tensioner and plugs at 100k miles. Ultimately goal is to pull 200-300 lbs out of it and do a few aero things to see if I can get her to 60mpg average. Its also not really a slouch the car is so light the 125hp suits it well so its not boring to drive either.
I drove a VW 1.8t for 9 years.... what a great engine, so I WAS excited to watch this small turbo engine tear down. What a junk engine! Thanks for the great content!
I have a 2015 fiesta with the first version of this motor and it was interesting to see they added a balance shaft. My 1.0 had a counter balanced... Balancer. I really like this engine in my car. Made a great sound. I killed my mine because I didn't notice a hose to my coolant reservoir broke and leaked all my coolant out and it overheated and now it blows white smoke like crazy. I still have it if you want it lol.
I've been quite curious about these little units for a while now.... all I can say is my face was contorted in disgusted ways most of this teardown! This engine easily deserves to be on the top of the list of worst engines ever designed and built!
Makes my HT 4100 look like an excellent engine. Actually, my 4100 in my 83 Eldorado has been perfectly reliable, still running fine at 182.000 miles. But I know they definitely aren't great engines. My meticulous maintenance has certainly been most of the reasons, and possibly i just got a good one also.
Plus it's ugly. The timing cover is ugly. The oil pan is ugly. The camshafts are ugly. We can overlook brutal design if a thing is useful, or if it is dependable. This engine is neither. It looks like something out of mid-70s Soviet factories.
I deal with cars everyday and the 1.25 is an absolute gem of an engine. Unless the car has had a major frontal crash that has physically impacted the engine, they always start! A very willing unit - and unusually for a 16 valve engine both torquey lo down and rev happy too.
I'm sorry but I've driven both. The ecoboost is a lot nicer to drive than the old 1.25. 0 road tax too. Not defending the wet belt design but no one can tell me the 1.25 good enough
these timing belts became very common here in Brazil, including ford ecoboost... the problem is the oil spec, if you use the wrong oil and/or use some additive the belt is destroyed
@@nlousapt Noted...my wife has a city turbo 1.0 3cyl with a belit in oil design. Maintenance with the correct fluids on these engines is critical. This is why our car has an oil life indicator. Fortunately, we don't even get to 10K kms in 6 months, so the oil is changed early. There have been a few issues with the engine - mainly poor / wrong maintenace, abuse or remapping. It's fast when remapped...but kaboom eventually...
I have a Ecosport with 110k km and 5 years. Nevertheless, when was the 100k service I asked to be checked if the belt was alright and how was the oil pump filter, and was everything clean. When reach the 200k km i will replace the belts.
This engine is another example that the primary goal of the auto industry is to take as much money as possible. When such a breakdown occurs on the engine, most people decide to buy a new or another car because the repair is extremely expensive. It most often happens when the warranty expires. The timing belt is perfect, quiet, safe up to 90-120 t/km and its replacement is relatively cheap compared to, for example, changing the chain on an Opel Astra 1.6 cdti. But on that same Astra, when it stretched, the chain started banging and people still noticed (those who occasionally listen to their car) and still went to the service center and prevented the engine from breaking down. That's why the engineers decided to put an end to it and decided to install a wet timing belt so that the engine is quiet, so that you can't look at it in the service center and assess whether it needs to be replaced. And that it breaks just when the warranty expires. And this is not only a problem with Ford, all manufacturers do this. The Japanese are no longer what they used to be, neither Mercedes nor any other.
I remember when this engine first came out. I had recently stopped driving my 3 pot 1991 Geo Metro and thought the idea of a small car with a 3 cylinder and a manual was not so bad. Then I looked at that wet timing belt and the amount of power they were trying to get from a 1 liter (about 2.5x that of the Suzuki 1.0 in the Metro) and knew that it would be a bad idea. I bought a new 2015 Prius C instead and it's been a great transportation appliance (if a bit unlovable). In 8 years and 142,000 miles, all that has failed is the A/C compressor (under warranty) and the 12 volt battery. With the Fiesta/ Focus/ Ecosport, they had bad engines and even worse transmissions, as well as poor fuel economy. If you want a good small car, you buy a Toyota or a Honda. Anything else just won't hold up.
And the funny part is, Yamaha gets 118hp out of an 890cc 3 banger with no turbo and that engine is known to be bulletproof. Of course it's in a motorcycle, not a car, but still MCs do some things that you'd never do on a car engine, like use the engine oil to also lubricate the transmission, clutch and stator, and also rev to 11k RPM and make most of your power at over 6k rpm.
Well....I just turned 100.000 miles on my 2017 Hyundai Elantra, with 0 repairs, and 0 issues. It runs smooth and quiet, uses no oil between 3000 mile changes. Even the brake pads are original, and again last week when having the tires rotated, I was told they are still good!! My 2 previous kias were also excellent.
I have a 2015 Fiesta with this engine, remaped to 160hp and 250Nm, with some mods, and it runs fine and like new after 130k km. I hope I'll keep it for some more years still. It is light, fun to drive and really economical when needed. From what I've seen, these little engines are very sensitive to maintenance indeed. The correct oil must be used, it should be changed regularly and it has to be the correct specification and viscosity. They are good little engines, but they need proper care. Thank you for your video. It was a lot of fun! Specially hearing that turbocharger spooling. Cheers
I had no idea these had 3cyl engines. Granted I never bothered to look - never thought these were nice vehicles, but this was quite neat to see. If you are able to find one, it would be cool to see an M132 engine out of a 451 chassis smart car - another 3cyl that have their fair share of compression issues. Take care, eric!
I bought a brand new 1987 Yugo with a 1.1 liter 4 cylinder NON fuel injected, NON turbocharged, 4 speed stick. I got 30 MPG city, 40 MPG highway and once got 50 MPG highway with a consistent tail wind pushing basically an old style Fiat 500 redesigned by the Frankenstein body works.
Thank you for your videos, I don't have an automotive background and you help with getting ready to try some engine repairs I might not have. So many different engine manufacturers tear downs gives me confidence in what vehicles I own lasting for many years.
Thanks for the video! To all Ecoboost 1.0 owners. Never use other oil than in specification. Because of chemical reaction with the oil pump and timing belts Even a small add on of wrong oil can destroy the belts.
@@metalted6128Good point, but at the end, you gotta follow the guidelines. The problem is a bunch of engineers trying to reinvent the wheel and complicating shit.
@@TheMadTube The FiST used the 1.6 Ecoboost engine. Oddly enough, that same 1.6 EB engine and 6 speed manual combo was sold for a few years in the last gen Fusion. It was oddly slow and not that efficient. Weird.
I wondered if someone was going to mention those. One of my bosses had a little metro with a stick shift and the little 3 banger with two squirrels and a hamster for an engine. It had 275k miles on it. Crap power, burned a quart of oil a week and rattled like it was an old guy with Parkinson's but it was a trooper.
I learn soooo much from watching you tear these down!! After seeing this, I would NEVER buy a car or truck that had this kind of oil pump and timing drive! Come on Ford! Didn't you learn anything from the Pinto with the rubber band design in the engines!?! MAN!!!!!!
This is my first time watching an engine get completely taken apart. I learned a lot from this video and the size of the engine is as small as it gets. Also, great video. :)
I love my 3 cylinder engine in my Mitsubishi Mirage now even more. Good old indirect injection, timing chain, no turbo. Very conservative engine. Low output, high reliability and durability.
Timing chain isn't that uncommon, especially on turbo engines. Unfortunately, ford never got the memo that there are quieter timing chains now that are drowned out by the fuel injectors.
I had a 1.0 focus, i loved the little car. It got like 40 MPG highway and 30 city real world. It was a great little delivery car. Mine was a manual transmission so it was kinda fun to drive in a geo metro way. I eventually sold it after it started making a weird noise at idle. It had been to the dealer like 5 times at that point for oil leak issues and i never got a loaner car, so I just gave up on it. It still had some power train warranty on it when I sold it so if the new owner had an issue, they were covered.
my parents had an 88 civic hatch, really made me love light little cars. so fun to drive, and frankly you feel like youre doing 100 when you're going 45 anyways lol.
I had one too. Loved it. ‘16 Focus w/ 6 speed manual. Sold at ~100,000 miles. Car was basically flawless - just rust spots on rear wheel arches. 54 MPG was my best tank. Would have kept if it was AWD.
I have a 2015 fiesta 1.0 trouble free even the duel clutch transmission is good, high way sits on about 3.8 4.0 litres/ 100klm, this are a good engine, as usual you need regular servicing
My thoughts too. Ford was putting out better cars in the 2000's. I personally drove that 2.0L over 225k before I sold it. Sold it for a what? You guessed it, another Mazda. The only thing I don't like about the next gen Mazda engine (same on the 2.0L) is the lack of port injection (gotta manually clean those intake valves..... again). Funny when I hear people say that the Ford/Mazda collaboration was bad. They don't know what they're talking about. Ford had better rust prevention at that time (look at the Mazda 3's) and Mazda is the new Honda will their engine designs.
Had a 93 protege lx with the 1.8L DOHC that engine was a gem good low end torque and could be rung out to the 7000 RPM red line all day. It took a loose oil filter( yeah the first oil change that I didn't do myself)and running it out of oil to lame it. Then running it out of coolant to kill it.
I had a 2001 protege with the 1.6L and a 5-speed. Those 1.6 and 1.8's just couldn't be killed. Fantastic engines, super easy work on. Mazda killed them because they were way too good (plus the only power was if you had a manual and no one knows how to drive one anymore ..)
Couldn't believe what a fantastic engine this was to drive when it was launched, Still can't believe what a bad job they did making it reliable long term.
My modest contribution. I have a 100cv Cmax 1.0 ecoboost from the year 2014. I have always done maintenance at the official Ford service, once a year and every 10,000 or 12,000km. It now has 102,000 km with no problems. I changed the timing belt for prevention, it showed no signs of wear or cracks and the system looked pretty clean. Never had any coolant leaks or overheating. I don't know how long it will last in good condition, or if it will eventually break, but I know more people with higher mileage and no problems. I drive it calmly, respecting the warm-up times and letting the turbo cool down before turning off the engine. I always used specific oil for this engine. I am aware that other users have used non-specific oils or 5w30 resulting in broken belts without teeth. I hope it helps, although the designers and engineers made a serious mistake by leaving the belt submerged in oil and giving such a small engine so much power
They really didn't go through much effort to obfuscate how intensely they wanted the engines to fail rapidly. I'm surprised that this is not a consumer protection issue.
I'd own another one in a heartbeat. Completely reliable if you do the oil changes early and use the right filter and oil. I drive over 40k miles a year and I'm an auto tech. So many people talking out their bums without any facts.
@@marvetheman The wet belt breaking up and clogging the oil pickup is a real issue affecting many cars and I just wasn’t prepared to risk it. I did do regular 5000 mile oil changes but the Ford oil was so expensive, whoops😁
@@marvetheman The facts are that it uses a belt for critical timing issues, and un-keyed sprockets to drive its oil pump. Regardless your claimed authority in all things mechanical, because someone paid you to obey some tabular data and get excited for more tabular data, the engineering is poor. Mechanics are not engineers, or they would claim to be engineers, along with the engineer paychecks. Meanwhile, it doesn't take an engineer, nor even a mechanic, to know that these design choices are both risky and cost-saving... A double-positive, from a financial expert's point of view... Hence, massive - and warranted - skepticism. ...or at least, that's what my bum tells me.
Hi Eric, here in Europe we’ve a lot of these engine designs with wet timing belts, Ford and Peugeot have had, shared diesel engines in the past, a lot of failures. One could replace this with an after market kit for a chain driven system. Here in the Netherlands we’ve a lot of owners of a car from Stellantis (Peugeot, Citroën, Opel, Fiat, Jeep etc.) with the 1.2 Puretech engine, having broken engines because the wet belt is clogging the pickup screen of the oil pump. Fighting with consumer organisations for compensation for the repair bills. I think these engines found their way to the USA in Jeep products, if you wondered about the flaws in this Ford design, when you get your hands on these 1.2 3 cilinder Puretech engine, you’ll see there’s even worse. But also the TFSI engines from VAG (VW, Audi etc.) with timing chains have had in the past their issues with excessive oil consumption and stretching chains. A lot of repair shops have a decent living setting the design flaws and/or bad choices regarding material choices, straight. Thank you for your very entertaining and informative channel! Love it!
Fortunately, Fiat/Jeep/AlfaRomeo did not use the current version wet-belt-1.2L-Puretech engine from Stellantis. I've got one of these engine on my DS3. Full rebuilt needed at 90k km due to abnormal oil consumption (piston rings dead) : oil is burnt in engine but petrol also mix in oil, degrading the timing belt that ends to a oil-picker clog. Stellantis announced next version will have a chain instead of the belt and will be shared with Fiat and Jeep. That will solve the clogging issue but not the piston-ring wear then oil consumption one.
Timing gears... No belts or chains. That is what manufacturers should use in their engines. Like some of the Le Mans engines do actually. But we never gonna see that coming. It would not generate enough cost after the warranty. All of that crap for the sake of ''ecology''. Clown world.
@@elzariantlp4594 Let's hope they do it better this time. We've seen what the psa (stellantis now)/BMW co-operation led to ... "prince engine". It had a timing chain and also lots of issues. p.s. I had a citroen c-elysee 1.2 puretech atmospheric. Sold it at little over 6 years. Belt was still in good condition. I now have a citroen C4 with the 100hp version of the 1.2 puretech with turbo. I guess the turbo versions (100, 110, 130 and 155hp) are more prone to belt degradation because of more blow by caused by the higher cylinder pressure. Causing the oil to get more hostile to the belt. My original service interval of my c-elysee said 10y or 180K Km's for the timing belt interval. Later stellantis lowered this to 6y and 100K km. However, still lot's of them fail before that. I would suggest people to replace the oil much faster. Like every 7.5K Km. (that's what I will do). And I use the one they specified for this engine (tested for additives eg) Total ineo first quartz 0W30.
I had considered 1.0 TSI engines for my new car, but man am I glad I found this video. If something can be called "a bean counter delight", this is one of them. This has so many "dynamic smartness" built in... only the accountants will be happy.
I have had two 3 cylinder engined cars in my time has a drive one was my dad’s two stroke 1975 wartburg which was run like a turbine the second was my last car a vw polo 1.4 tdi diesel which was very torquey also very economical but a bit rough blowing 2.000 rpm I had the car for twelve years and it never missed a beat I tried it with 110.000 miles on the clock for my 2015 1.6 4 cylinder diesel Vauxhall Astra which is given my a average of 60 mpg on the motorway in sixth gear at 70mph 75 mpg it having the extra cylinder makes it run a lot smoother and also it’s very quiet I don’t think I would go back to 3 cylinder engine again or petrol car
@@bassmanjura yes my sons partner has a petrol vw polo 1.0 atomic and my son has a 1.2 diesel he loves driving her car because he got lazy and likes not having to manually change gears he also says her polo has plenty of power and delivers good mpg
I'm an old school but very much educated mechanic and all around tech person. I'm 64 and have an A&P Fed lic and diesel lic along with decades old auto certs. I don't care what they make that belt out of to run in oil, it is still a belt running in oil. Yeah, I'm not on the level of an engineer but logic tells me that chains AND gears work better, last longer than any other type drive system. I work on industrial engines of smaller size up to 3.0 inline 4 cylinder. Take how Kubota has used GEARs on their timing system forever and they still make the longest lasting and trouble free engine in my line of work. We have GM industrial engines and Mitsubishi that use the dry belt BUT use an all aluminum head that the MFG says to just throw away at 5000 hours. That is an insane type of regular "maintenance" for an engine IMO 50 year experience of working on this stuff. Today's engineers have got MAD. IMO of course.
Two main failure modes for this engine are oil pump filter mesh blocking with degraded belt debris (like your example), prevented to the best of my knowledge by regular oil changes (more frequent than specified) and ensuring use of correct spec oil. Second failure mode is due to coolant loss and the fact that water temperature sensor can report "Normal" temperature even after fatal coolant loss and head gasket failure. I had a 1.0 Ecoboost fail with coolant loss overheating (just over 60,000M on the clock, in a Focus). I had brand new engine fitted free of charge by Ford. This was essentially due to this type of failure being caused by the design flaw of being unable indicate fatal coolant loss and overheating along with hose issues causing coolant loss in the first place. 1.6L Ecoboosts had a safety recall and a low coolant sensors fitted (with buzzer and light), due cracks in head potentialy causing a fire. Later 1.0L Ecoboosts have an engine block temp sensor to force engine into limp mode if temperature is excessive.
Seems to be a common thing on the smaller ecoboosts. I used to have a coworker with an Ecoboost Fusion and despite him also being a Ford tech who kept his car in very good shape, his car blew a head gasket on him. Never had an ecoboost myself, although I did have the precursor to one. I used to have a Mazdaspeed 3, so it had what would become the Ecoboost 2.3. Never had any cooling system problems, although it did eventually get the timing chain rattle. And I changed the oil every 4000 miles or so. And that wet timing belt design is just stupid. The worst of both worlds. I'm a Honda tech, so I have plenty of experience changing belts, mostly on J series V6s, but I've done a few older D and F series belts too. Those are nice and easy to take apart. I've also put chains in K engines due to stretching. It makes no sense to add the extra work to do a chain when you have the service interval of a belt. Plus it's much more suceptible to failure than a traditional belt or chain design as a result. It takes serious effort to make something THAT bad. How did that make more sense than just using simple plastic covers like most engines with timing belts use? Especially when it's certainly cost them a lot in warranty claims. Between this and the dual clutches that eat themselves, I don't trust any Ford made small car anymore. And I love compacts and subcompacts (I daily a Honda Fit, and I've owned multiple Honda Civics, 2 Nissan Sentras, a Ford Focus, a Toyota Corolla, a Toyota Tercel, a Dodge Neon, and a Geo Metro, all of which I had fun driving)
Yep they're also responsible for a few deaths due to said fires and when they caught fire, the central locking trapped the people in the vehicle, unable to get out. More than a few cases in Africa that made the news.
It's a shame too, the engine could have had so much potential if these glaring issues were avoided. I've always been interested in what manufacturers can do to get power out of such small engines, it would have been nice to see more success from this design and ultimately more power.
That was the fuel pump bucket that fell out when you pulled the cams out. Fuel pump sits inside of it. Common failure point when people don't change their oil. Also the tensioner on the balance shaft was a problem for breaking. Just like what happened on this one. I never came across any at the dealer that had cylinder cracks.
I was wondering if that bucket had wear issues. The VW EA113 FSI motors used a bucket like that too, and it was pretty much routine maintenance to have to replace them
@@tally5k339 yeah I ran into a lot of "my friend up the road is a mechanic and changed my high pressure pump". But he never changed the bucket which was the initial problem. Wore a hole in it ate the camshaft and ruined the pump
@@BeardedFordTech usually the exact same story over here in VW land. Bucket would get worn through, leading to the cam and HPFP piston having a grudge match and destroying each other. It's funny how 2 manufacturers can make the exact same mistake, but I'm guessing the customers aren't as amused
Used to drive a Focus with one of these in quite a lot. They're not fast, but they're certainly quick enough, particularly on a fun twisty road. I used to get about 40mpg (UK).It went for a "quick service" at Ford at about 40,000 miles with some interesting rattling noises on idle, and didn't come back for well over a month... pretty sure that was a new engine under warranty. A colleague of mine bought a Fiesta with the same engine a couple of years ago, he knew what he was getting into, so he factored in the cost of a new engine one day when he bought the car and just keeps that money set aside. He's not needed to spend it yet.
Oddly enough, as a Ford dealership technician since 2000, I have yet to see one of these gems. After doing countless phasers, chains and water pumps on 3.5s both NA and GTDI, along with 1.5 short block and 2.0 long block replacements, I have yet to come across one of these wet belt engines.
The thing with these engines, is they do run well. As long as you treat them as such. Running the belt in oil is so-so, granted, but to be honest - most of them work just fine and live a long life. They're particular about the coolant and oil they need, but other than that, they're decent little engines. Not the best, mind you, but by far not as bad as most people make them out to be.
"I Do Cars" Hopefully NOT for a living - I've not seen such an incompetent mechanic in many years of being in the industry.

In the UK these engines are known as "ECOBOOM" for their ability to self destruct. Great teardown, enjoyed this one.
UK autos example Jaguar, Range Rover etc. need I say more.
@@gonesideways6621 and they’re going out of business in the next 15 years!
The ecoboom name came from a cooling pipe fault in the early cars. That issue is long gone

Now *that's* funny! ECOBOOM 😂
As a Ford tech for a little over 2 years, this is the 6th time I've personally seen this happen, not including the rest of my shop. What we hear is either 1. The tensioner itself fails and there is no longer any oil pressure, or 2. The timing belt loses every single tooth (likely still tensioner failure) and becomes smooth and of course, no oil pressure. Most cars will keep driving like this until the "Low Oil Pressure" warning crops up, at which point we get it. There is no recall, but ford issued a TSB which directs to replace the long block and turbo. Which is why they are in such high demand. Obviously just a horrible engine design. Absolutely loved watching this one. I also hate that turbo vacuum line, and there's always one fuel injector connector that gives me hell. Great teardown!!
Ecoboost across the board are trash
@@shadowopsairman1583 the only one I almost never have issues with is the 1st gen 3.5, even with half-assed maintenance. I've owned 2 and worked on many. But all the small ones are a pain to work on and have numerous issues. Both 1.5's especially. So yes, I'm inclined to agree.
since u have only seen 6 of these failures means theirs only 6 of these engines in your area.
ive replaced 2 1.0l ecotrashes so far. first one belt failed and lost compression and the second one they drove it in at 0 psi of oil pressure and surprisingly it still ran great
Can you say anything about the 2018+ 2.7 EB?
Ford needs to have a new car called the Ford Triple Threat -- it uses the wet belt system, the Power Sh*t tranny, and the old Pinto's "built-in-BBQ" rear gas tank
I remember when Ford introduced this engine. Part of the marketing included demonstrating how just the block, or the block with head on it could fit in a suitcase. Seems that was intentional not to show how compact it was, but a new mode for transporting replacement engines to dealers.
Yeah they were total idiots with all the crap they were saying about that stupid engine.. I was like "WTF"
Stupid crap, Ford deserves what's coming to it.
Saved on shipping! 😂
europeans are convinced this exact engine is one of the BEST bc europeans are used to even worse garbage from VW (VW engines that were never offered in america) LOL
Totally remember that article. The Ford engineer took it in his carry on luggage.
I really like the use of a plastic thermostat housing living right next to the turbo.
its super genius, Corvettes should have it too.
turbo so tiny they thought it wouldnt generate enough heat
Looks like that is more reliable than the tensioner so it doesnt matter long term anyway
What could possibly go wrong. One of those miracle high temperature plastics no doubt
I think the designer got shit-canned and decided to sabotage it.
All the engineers who worked on this cried when they were told it had to have no timing keys and that they couldn't afford either a timing chain or seals for the belt. Only the accountants went home happy that night.
Still....
There was this one engineer, maybe a team, who stood their ground. They may have risked it all. Their careers....everything.
I salute the head bolt team. That was unexpectedly satisfying
As the recalls roll in, the accountants realize they had successfully sabotaged Ford, once again.
Loads of modern engines do not use keys. It gives more accurate timing. If the bolt comes loose, the key won't save you, anyway.
However, keyways aside, an engine does need to be designed competently and we see a few howlers, here.
@@camshaftcasting1451 just because loads of manufacturers don't use them doesn't mean its not a shit idea. It's designed to make them hard to work on so they go back to the dealers, ideally to the tip when the engine shits, don't pretend its for more precise timing, what a crock lol.
As a Ford Mechanic from Germany I service the 1.0 Ecoboost alot. First of all the 1.0 is extremly sensitive, service it well and don´t mistread it and it will run for a good while, but make one mistake, ( run without water/ put in the wrong oil/ abuse it when cold...) it will die on you garanteed. I have seen allot of Timingbelts and Oilpumpbelts like that because someone put the wrong engien oil in wich then started to degrade the Belts. Takes only a few weeks for this to happen with the wrong type of Oil. Also the Cranksshaft isn´t keyed so the belt can balance itself when you tension the new Timingbelt, because you need to lock the VVT units and the camshafts when changing the belt. That also means you need to take out the starter motor and put a Flywheel lock in so the Crankshaft can´t turn when you change the Belt. The New 1.0 Ecoboost now has a Timingchain, but for some UNBELIVABLY STUPID REASON (mostlikly money). The Oilpump is still Beltdriven. So you still need to tear the engine all 10 years or 200000KM/125000miles apart just to change one small belt. Facepalm!! Also the waterpump is now Driven by a Dry theeted Belt wich is Driven by the Camshaft end by Cylinder 3. YAY. Pls end me know.😥
I never liked the concept of turbo charged tiny engines.
@@jeffsaxton716they are absolutely fine when they are not designed by monkeys high on crack.
I understand that on this engine there is no key way for the oil pump drive (a seperate belt to the crank belt) The oil pump though needs no timing like crank!!
My 2006 S430 is nowhere near that delicate.... Almost 300,000 miles on it now... That car is a beast. It doesn't know what quit or die means.
Thank you very much. Can you tell me if that new little oil pump belt is Dry or Wet (in the oil) ? Thanks
This engine was designed to survive just long enough for the car to be out of warranty. Also, Ford hasn't keyed their timing components in at least a decade. It's all held in time via tension. They even make special tools to lock everything in place anytime you need to undo the crank pulley. Because that bolt is the only thing keeping the engine timed.
Same with VW
wait 'til you get one of those shitty Peugeot 3-cyl ones. they destroy themselves way before the warranty is over and Peugeot always try to put the blame on you... 😹
The older Mazda L engines(MZR 4 cylinders) also didn't have keyed cranks. This channel has 3 teardown videos for the turbocharged 2.3 engines and Eric wasn't happy any time he had to touch one.
Mazda's own Skyactiv engines have changed the crank to have keys, but some of the Ford Ecoboost 4-cylinder engines are based on/have design influences from Mazda L engines, so they still lack crank keys.
I'm not an automotive design engineer. But I have worked on several models of older American engines. V-8s of course. Is there any other kind? OK. Straight 6s can be great.
The lack of keyed belts still stuns me. Am I correct that the tensioner made of plastic, that had disintegrated, was all that kept the engine timed? Unbelievable.
It must be a non-interference engine because there was no evidence of valve damage?
American Ford V-8s could be be poorly designed. A 289 1966 Mustang used a cam gear with nylon coated teeth. The nylon would wear down and cause the incredibly strong metal timing belt to slip a tooth or two. Hopefully no more than that.
Why? It made the engine quieter. And probably accelerated planned obsolescence for Ford.
I followed a ford puma the other day and one of the exhaust pipes was still shiny inside.... They've welded a second pipe by the side of the real pipe to make a fake twin pipe exhaust to make it look like a powerful car.
I've also seen 3 new ish pumas with rusty non functioning back brakes.... Dopey owner driving around for 3 years in a new car with only front brakes... 🤮
As an ex warranty administrator for Ford here in the uk I can say we changed dozens of these engines under warranty. We were doing several a week! It’s a completely poorly designed engine with little robustness. We had them meticulously maintained and still failed. Ford technical told me they were stressed to the limit the minute they leave the production line and have no resistance to any faults like low coolant. In the end we didn’t even bother stripping them down. Just fit new ones. Must have cost Ford millions in warranty repairs. Same as the 2.0 litre eco blue diesel in the Transits. They have tarnished the Transits reputation.
I watched the BBC news story on this. It clearly showed where coolant had leaked into one of the cylinders. I believe that it was a 1.5 L.
Very surprised Ford allowed this design to go into production!! This wet belt type must have limited life - with such destruction by the belt through the oil pick up etc When the engine was stripped!! (Even the tensioners were damaged too)
Thanks for your information. Didnt no that!

I think that Ford labels that car as “Eco” because it is cheap for them to build. That’s it. Never intended to be cheap for the customer or in fuel. Great video, as always, Eric.

Eco stands for engine cheap option 🤣🤣🤣🤣
I thought "Eco" means they're biodegradable :)
I've seen redundant systems before, but never redundant failure modes. If that oil pump belt didn't get the job done, that timing belt was ready to let go at any minute and finish the engine off

My wife's ecoboost Focus engine split a coolant pipe(plastic) and dumped its coolant in a few seconds, overheated in under a minute and conked. A Ford replacement was 1400 pounds sterling, and with a new clutch and flywheel fitted our bank account was minus 3600 pounds sterling. This was a 15000 pounds sterling car that had only covered 75000 miles. We still have the car and it is now on 108000 miles. Our daughter is having it as her first car and hopefully squeeze another few thousand miles from it. Thanks for the engine breakdown vid, I hope they have sorted thise daft belt probs out.

I'll always remember the advice my Dad gave me. "Son, it's just as easy to find an engine that DOESN'T have an oil-soaked timing belt."
Ha, ha! True that.
They are very eco friendly because they're always catastrophically broken so they're never running 😂 We had one that shut off on the customer, it would crank but not start. Pressure tested the cooling system and cylinder 2 filled up the spark plug tube in about 2 seconds. Engine overheated so badly you could feel the warped spot between the block and water jacket lol.
The engineers really worked their asses off to make these as cheap and quick as possible to assemble. Which is good, because they'll be replacing a lot of them

Hi, "I Do Cars" -thank you so much for this video.
Long story short, I've owned a 2014 Ford Fiesta 1.0L since day 1. today in 2024... that thing is running like new.
of course, I can feel the plastics shaking and vibration from wear... but the engine, I have nothing to say about it.
My oil changes have been ON TIME. Maintenance is key, changed the spark plugs at 100,000 Mi, same with the Coolant and the belts (all). I had to replace the water pump and that's it..
I am very happy with this little engine.. It does gives a 45MPG on highway... and about 38.5 combined. Stilll.. yes still after 10 years and 140,000Mi...
Thank you for this video, I will be happy to do more on my little engine to last longer... Cheers!
You even had the pre coolant system fix year. I have a 2016 with 130k, oil changes, plugs, air filters, and it’s doing great. I did replace my suspension components after driving a few too many Uber rides with passengers pushing me well beyond the payload capacity of the little car. Probably will buy a used replacement engine so I have one on the stand ready to go with a new timing belt, and when the used engine hits timing belt time swap them around. Here’s to hoping our little Foxes keep running strong.
I have 2013 fiesta 1.0 ecoboost with 150.000 on it and it still runs fine .i did have to replace the dps6 transmission this week because it was more a noise complaint for a few months because it may have a few busted bearings the fault is mine i never changed the oil but it only cost me 2400€ for a refurbished one and built in and that transmission is working fine

I think it'd be interesting to see you do a tear down with an engineer that helped design the engine. If they are no longer employed by the manufacturer then hopefully they could give honest answers about the design decisions they made and the constraints that were placed on them.
They would tell you they were forced to by upper mgmt which is very likely the truth.
never seen a wet timing belt design. Never new it existed.
Packaging, crash safety and cost. Just survivable past warranty.
@@thegrandhoovalation a 3 year motor or something.
id like to beat the sh1t out of designers.
This engine is also used in the Fiesta, in 100, 125 & 140 hp. Despite being calld 'eco', the fuel consumption was only slightly better than the previous normally aspirated 1.4. The 1.4 was just an adequate engine, burnt a bit of oil, but will probably outlast all the ecoboosts.
Here in Europe, no keyway is becoming more common. Like you, I think the main reason is cost, but the excuse given is that the timing is set using holding tools, then the bolt tightened, so the timing is more accurate than being fixed by a keyway.
My brother left a breaker bar on his crank pulley (Peugeot 307 2.0 petrol), hit the starter, bar hit the chassis, undid the crank bolt, timing moved, valves bent. Oops!
The no keyway thing it's just a straight up cheap move.
Glad Mazda moved away from it.
I'm baffled by why this engine and car exist with such terrible fuel economy. The Toyota 5S-FE (2.2L I4) in the XV20 Camry was a basic NA engine with an ancient 4-speed (3+1) auto was rated 21/27mpg on the EPA cycle. Admittedly that standard has been updated but I personally saw 29-30mpg on long highway trips with the AC running. The Ecosport is about 300 pounds heavier and has more emissions criteria to meet but...how can it be 25 years newer and still be this bad?
My 1L gets ~40mpg in my fiesta. I’m sure there were different variations but some of them got really good fuel economy
@@aaronvienot Ford EcoSport uses a more reliable torque converter automatic transmission, not a DCT (Dual Clutch Transmission), which effects fuel mileage.
No keyway is madness for the timing-critical parts. Hell, even way back in the 70's and before, they used keyways to make sure things could not get out of basic alignment. There were always ways to tweak the timing in other ways back then.
I had a 2014 Fiesta with the 1.0T. Started exhibiting head gasket failure symptoms (cold start misfire, no heat due to air in cooling system) around 40K miles on it. Ford put a new engine in it under warranty and I sold it not long afterward. Having seen this teardown, I’m glad I did. Their paperwork said “cracked block” - assume they meant cracked head.
It was amazing on fuel, torquey, and sounded neat - neat enough to get my car/youtube video featured in a Jalopnik article on “cars that sound better than they ought to.”
No, they do mean cracked block! They cut a channel between the cylinders and that apparently cracks, giving the symptoms of a head failure whereas you really need a short block to fix the engine. Or a complete swap of everything.
Regarding fuel economy, EPA rates 1.0T Focus worse on fuel compared to, say, a Mazda3 Skyactiv 2.0 from the same era while making LESS power. EcoSport was also rated worse on fuel than Mazda CX-3 or Honda HR-V, both with larger NA engines that make more or similar horsepower. Given the lack of displacement tax in North America and the issue with Ford Powershift, I'd love to know the reasoning of anyone who bought the car.
This is why I am glad North America doesn't have displacement tax because then you get terrible engines like this. In a Fiesta or Fiat 500 I think it's fine, but in a Focus or EcoSport, the displacement is just too low and so you have to constantly rely on boost, which destroys fuel economy(engine has to run extra rich to prevent knock) and engine longevity. If you have to have a tax, base it on fuel consumption or emissions, not displacement.
If a turbo engine is not on boost it is inefficient equalling WORSE fuel economy due to lower compression to allow for the increased cranking pressure of the extra air blown in due to the turbo.
@@gvicj05 I'd say it's a bit more complicated. My Subaru on boost was thirsty, keeping it off was more efficient but less fun. My direct injection 330i was very efficient, unbelievably efficient. So much so that my 1.5l Ecoboost couldn't match it and you needed it in boost all the time because there was no power without it, and would leave you limping out of junctions dangerously. My current 320i does have turbos and you can hardly tell it's a boosted engine, and is even more efficient due to the direct injection. I'd say direct injection is the key to an efficient engine, turbo or not.
@@johnsim3722e said that an engine with a turbo not in boost will be less fuel efficient than that same engine without a turbo, which is true due to parasitic drag.
Car industry making engines over 100 years and they came up with this genius design in 21st century

On the negative side, the oil-soaked belts mean the engine will fail relatively quickly.

Actually... you'd be surprised. My aunt and uncle had (or maybe still have) an EcoSport and the engine was nothing but trouble from day one. It was taken care of but seemed to chew up a belt like this one did every 20k miles. I think it spent more time in the shop than it did their possession, but the transmission never went out.
I hit the transmission lottery with my 2013 Fiesta.... for a while, at least. It went in for the recalls, and every once in a while it would shudder, but the TCM going out at 132k did it in back in 2021. After six months of waiting I bought a new car, and here we are almost two years later and it's still sitting on the lot, not fixed. A shame, because other than the TCM I never had an issue with the car at all. Ran great, got amazing gas mileage, and the only time it left me stranded were dry rotted tires from sitting before they went on my car. Wasn't obvious at the time of purchase, unfortunately.
They didn't use the dual clutch on the 1.0 ecoboost. They had a 6F15 torque converter transmission and a manual transmission option.

Shockingly GM has a wet belt in at least one of their new diesel engines, I think powering the oil pump, and you have to pull the engine or trans to get to it. Imagine spending the diesel tax, and having this junk in your engine.
Sadly it's probably going to be a trend to keep cars from being too reliable and keep them failing so you have to replace it with a "cleaner" new vehicle.
The 5.0 Coyote is probably the best modern engine they have. The old 5.0/302 from back in the day bc was a good one also.

I was one of the first to buy one in North America: I ordered a new 2015 Focus, 6-speed manual, a couple of months before that engine was added to the Focus plant in Michigan, based on the good reviews the engine was getting in Europe (this was in 2014, before the problems became known). I drove it daily here in Canada, summer and winter, and put 330,000km (a little over 200,000 miles) on it WITHOUT changing the timing belt or touching the engine in any way, other than regular oil changes and a set of spark plugs! I guess I was really lucky....I sold it in late 2021, as I was having some transmission issues...and by that time it was apparent that the belts were a ticking time bomb. I was getting rather nervous about the belt failing, and having read up on the belt replacement procedure (special tools required to align everything because of the unkeyed shafts) I decided to let her go. It served me well, although the fuel economy was good but not as great as I had hoped. I think the reason it lasted as long as it did was the fact I was driving highway, 77 miles to and from work, each way. I did run the heck out of it, though, you could rev those things up pretty high! I always said it wouldn't win a race, but it wouldn't get in anyone's way either. I think what really kills the belts (other than having a belt run in hot oil in the first place) is city driving, the 240 degree power pulses of a 3-cylinder at low revs must put a lot of stretch-and-release tension on them, no wonder the teeth shear off! I miss the ease of service of my 1993 Escort from years ago, I could change the timing belt in 45 minutes in my driveway...no such cars nowadays. :-) Keep up the great work!
I currently have a 60k 2018 Fiesta with that Ecoboost engine and honestly I've found it's okay compared to various other engines I've experienced. You may find it hilariously small but in Europe it's a more "sensible" size. I would suggest that the overall failure of that engine you have there is belt degradation which secondarily blocked the oil pickup for a lack of oil pressure. This is a known thing here, you have to religiously use the correct oil for that belt, a Castrol/Ford recipe based on 5W20 and nothing else. If the oil pressure light comes on, you stop and call for a tow, do not attempt to drive home. Thanks for doing a ecoboost!
My 2.2L GM Vauxhall Vectra was literally priced off the road for being a Gas Guzzler. I replaced it with a 1.4 litre Golf that does 50MPG so the annual road tax is less than 1/3rd of a tank of fuel. Of course old Tesla Model S drivers will have the last laugh paying no tax at all.
Tesla owners will be constantly replacing thier Teslas because they are not made well
@@MrDuncl their car insurance and service interval more then makes up the difference.
Tesla owners need to replace their testes for being scared to burn a little of that sweet sweet guzzoline.
@@Imperial_Boltgunbest Tesla related comment ever 🤣
I have an 18 Focus with one of these engines. Typically see 44-48 MPG on it with the 6 speed manual. From all I've heard and seen, the first few years had bad rubber/plastic for the cooling system externally leading to more overheating issues, but all years share those little coolant passages between the cylinders. Later 1.5L 3cyl ecoboost have a small passage drilled a bit deeper so coolant isn't touching the head gasket.
Additionally, the belts are meant to be maintenance items at 150k miles, though I'm not sure how realistic that is with 7.5k mile oil change intervals, so I change mine every 4-5k. Every time I have seen this failure, the same symptoms happen, making it hard to know the cause, but effectively the oil pump locks up and sheers the teeth off the belt. Given both belts have continuous oiling from the oil pan by being dipped in, it seems like junk gets in the oil pickup and stops the flow. Whether that is sludge from long intervals or bits of the belt cracking off as gas and carbon get into the oil is hard to say and know as it kinda all looks the same when it is small.
The belt is materially designed to not decay from being in oil, but I don't know what amounts of gas might do to it. That said, I think the most important thing is checking oil level (should be cooler oil then) and condition. I saw plenty of Equinox have stretched timing chains and is was anywhere from 60-120k miles, a shorter interval than these belts for replacement (while timing belts for GM were 100k and chains started becoming 150k on the newer Colorado's timing chain). Though I figured you'd have to take the head off to get these belts off... there goes my idea of an almost engine rebuild and check at 150k miles. I was hoping it would be like the GM V-8 with AFM where you see almost no head gasket failures in them... because you see lifter issues and the head gaskets are replaced when you do lifters. In my ~4 years at GM I saw a LS head gasket failing once, but lifters hundreds of times. Was ~$3.5k if it was just lifters, $5.5k if the cam was bad and ~8k for a new engine installed. I'm interested to see how my 1.0 does compared to my 302.
These engines were only designed to last 60,000 miles just long enough to cover the warranty period 👍
My 2012 Focus 1.0 ecoboost is on 77k I’ve had it 4 years and apart from a fuel leak and a battery that died it’s hasn’t missed a beat. I don’t know how your epa fuel rating works but I have recently getting 47.2 mpg
@@johnfullbrook628 I've had my 2016 Toyota Auris 1.2T I4 for 4.5 years, its on 72000 miles and has had no mechanical issues at all outside of wear and tear items and servicing. It is bigger, more refined and doesn't sound like its misfiring unlike a 3 pot yet its still able to return more than 50mpg. Best part of all its chain driven rather than belt driven mean it won't have a costly £1000 bill for belt replacements.
@@gravemind6536 i agree I think the wet belt over a chain is stupid considering how many hours labour it takes to change it. Ironically the 2006 Focus that it replaced was a chain driven engine and I traded that off with 140k on the clock I’d say the mk2 Focus was a much better built car as this mk3 has had silly little things needing to be done and it’s only on half the mileage
Here in Germany they blow up at around 60 k kilometers, not miles!
@@gravemind6536my 3 cylinder Toyota 1KRFE in my Aygo gets 61 mpg and if I go slow without air con on, 78 mpg.
As a time served (marine) fitter I love the sound of well torqued bolts breaking loose. That crack as it breaks free is music to my ears.
Here in Brazil, we've been dealing with those three cylinders engines, wich push the Ford Ka vehicle since 2014. We've regularly been dealing with that timing belt failure you've faced, when the timing belt loses its teeth. It's been caused when owners use not specified oil for a long time and timing belt starts to lose teeth or releasing material, wich block the oil pump. That engine has another serious problem I've faced so many times: in some cases, the engine is running with no oil or with low oil pressure and there's no oil indicator blinking. When you finally realizes the engine has lubrication problem, the engine is destroyed. 🤦🏾🤦🏾
Long story short, you have a bunch of car owners not following guidelines, neglecting their cars. Then when they break, they say "you should have bought a Toyota".
I've noticed this on a few Fiat 1.2l engines. The tiny ball inside the oil pressure sensor seems to stick in the "everything is fine" position 😅
@@mrdomhare Ford and Fiat, I guess we better avoid 4 letter brands starting with F.
@@bmw803 To be fair having a wet belt is just asking for failures nobody expects. Timing belts will eventually fail and with this system they will send pieces into your oil.
@@Alobster1 That I ain't gonna argue. It's definitely STUPID. Put a chain and forget it. They want to save on a chain vs belt, but spend how much more replacing engines when they fail.
That air gun makes for more boost than the actual engine 😅
It's not about massive performance it's for the masses cheap small small engine
Believe it or not they run 22psi stock.
that turbo was the least of the problems.
Great video! When this engine first came out, I was fascinated by it. Here in the UK, Focus, EcoSport, Fiesta, Mondeo, they all had this engine. And it is known as EcoBOOM. Because there are 3 recognised ways it can implode. Ford will only replace, for one of these faults. They would know, all 3, from bench testing 😳
What are the 3 common issues?
I am not entirely certain, but I think the best advice is avoid the engine 😀@@MrWilliam.Stewart
A very solidly poor design.
@@JohnDough-yr2zt sadly yes. It sounds fantastic, being a 3 cylinder, but I would not touch one with a barge pole 😂
@@MrWilliam.Stewart One's the timing belt, the other is a coolant pipe that's prone to cracking and dumping all your coolant, and I believe third is a miniscule cooling channel between cylinders that's prone to clogging and blowing the head gasket. I'm so glad I went with the I4 Duratec Ti VCT in my Fiesta.
Been using these engines for the past 10 years and never had a problem with them. My latest 155hp in my Fiesta ST Vignale is an absolute gem
Great teardown as always! Thank you! I don't know if anyone already mentioned this little fun fact: this engine was voted "International Engine Of The Year" (in its category) many times.
That was before anyone used one
Was the category "worst possible design"?
Once you attach it to a turbo it’s guaranteed to be a worst design. Cooks the oil the longer it runs. I wonder whether they slap one on to make sure the engine doesn’t last. As long as it has overdrive I’ve seen V8’s get nearly the same mileage on the highway and they don’t have as many problems with reliability.
@@kevinstonerock3158 the turbo is water cooled and has a turbo timer....
That award is a joke, the VAG 1.4 TSI (twincharged) won it twice and it is well known as a pile of garbage.
It's a shame, they could've made this engine so much better with little changes to it's design, and it'd probably be quite reliable, but the way they did it is just crazy.
Yeah. Without wetbelt it would look like they're quite ok little engines.
It's exactly as designed, a cheap car engine that's expendable right after warranty so you'll be in market for a new car. First time with Capitalism I presume?
The only car you would want to swap IN a rotary engine.🤣🤣🤣
you could break it down, replace the seals and put it back together in the time it took to look at that ecoblah!
The new version for a few years now has a timing chain, not belt
@@cuddlefish999 Thank god. That was a good decision.
I absolutely love this 999cc ecoboost motor, my 2016 fiesta sedan averages 52mpg with a best tank of 56mpg. It was dubbed the sfe (super fuel economy) and was an option with a 5 speed manual in the 2016-2018 fiestas in the US. Ford hugely under rated the fuel economy of these motors. Mine is listed as 31 city, 43 highway, 36 combined. And it actually gets 40-50% better economy combined. Highway only at 60mph the economy sits in the 65-70mpg range. I bought the car used dirt cheap and has been amazing as a daily driver. The only issue ive had so far is a leaking coolant tank that cracked at the outlet barb, got a new one for $35. I do plan to replace belt, tensioner and plugs at 100k miles. Ultimately goal is to pull 200-300 lbs out of it and do a few aero things to see if I can get her to 60mpg average. Its also not really a slouch the car is so light the 125hp suits it well so its not boring to drive either.
Cuz its behind a tow truck all the time..
I drove a VW 1.8t for 9 years.... what a great engine, so I WAS excited to watch this small turbo engine tear down. What a junk engine! Thanks for the great content!
I have a 2015 fiesta with the first version of this motor and it was interesting to see they added a balance shaft. My 1.0 had a counter balanced... Balancer. I really like this engine in my car. Made a great sound. I killed my mine because I didn't notice a hose to my coolant reservoir broke and leaked all my coolant out and it overheated and now it blows white smoke like crazy. I still have it if you want it lol.
Really, 3 days later and still no takers?
@@twillison8824 If anyone has a line on the version of this motor I need that would great.
We sold 2 fords and bought 3 mazda's
I've been quite curious about these little units for a while now.... all I can say is my face was contorted in disgusted ways most of this teardown! This engine easily deserves to be on the top of the list of worst engines ever designed and built!
Makes my HT 4100 look like an excellent engine. Actually, my 4100 in my 83 Eldorado has been perfectly reliable, still running fine at 182.000 miles. But I know they definitely aren't great engines. My meticulous maintenance has certainly been most of the reasons, and possibly i just got a good one also.
Plus it's ugly. The timing cover is ugly. The oil pan is ugly. The camshafts are ugly. We can overlook brutal design if a thing is useful, or if it is dependable. This engine is neither. It looks like something out of mid-70s Soviet factories.
@@1958Cadillac-v2g I see another person that likes to self inflict pain. Mind you, your ht4100 is miles ahead of my Olds Diesel
Meh hold my beer.
You guys like Audi's and BMW's? 😢😂
It looks like something communists would design and make everyone use.
Old 1.25 4 cylinder in Fiesta was a little perfection. Just 80hp, but very usable torque curve and it was joy to drive in town.
That's because it was developed with Yamaha
Yes we have a 1.4. Small power but a charming little engine that loves to rev.
I deal with cars everyday and the 1.25 is an absolute gem of an engine. Unless the car has had a major frontal crash that has physically impacted the engine, they always start! A very willing unit - and unusually for a 16 valve engine both torquey lo down and rev happy too.
I'm sorry but I've driven both. The ecoboost is a lot nicer to drive than the old 1.25. 0 road tax too. Not defending the wet belt design but no one can tell me the 1.25 good enough
Here in North MERIKA, we will blow you off the freeway with our V8 F-150s. HA HA HA HA HA!!!!
At 30:36 ... The mirror hanging on the King Ranch is priceless, as are all the scratches down the side. The fitting end to a Ford.
these timing belts became very common here in Brazil, including ford ecoboost... the problem is the oil spec, if you use the wrong oil and/or use some additive the belt is destroyed
Yes. 21:45 that's the most common problem on that engine. Poor oil or not changed on time and debris of belt will block the oil pump filter.
@@nlousapt Noted...my wife has a city turbo 1.0 3cyl with a belit in oil design. Maintenance with the correct fluids on these engines is critical. This is why our car has an oil life indicator. Fortunately, we don't even get to 10K kms in 6 months, so the oil is changed early. There have been a few issues with the engine - mainly poor / wrong maintenace, abuse or remapping. It's fast when remapped...but kaboom eventually...
I have a Ecosport with 110k km and 5 years. Nevertheless, when was the 100k service I asked to be checked if the belt was alright and how was the oil pump filter, and was everything clean. When reach the 200k km i will replace the belts.
I think, you should strickly use SILICONE oil on these engines:)
@@bostjanerjavec4146 silicone oil is very hard to additive, became too expensive for car use
This engine is another example that the primary goal of the auto industry is to take as much money as possible. When such a breakdown occurs on the engine, most people decide to buy a new or another car because the repair is extremely expensive. It most often happens when the warranty expires. The timing belt is perfect, quiet, safe up to 90-120 t/km and its replacement is relatively cheap compared to, for example, changing the chain on an Opel Astra 1.6 cdti. But on that same Astra, when it stretched, the chain started banging and people still noticed (those who occasionally listen to their car) and still went to the service center and prevented the engine from breaking down. That's why the engineers decided to put an end to it and decided to install a wet timing belt so that the engine is quiet, so that you can't look at it in the service center and assess whether it needs to be replaced. And that it breaks just when the warranty expires. And this is not only a problem with Ford, all manufacturers do this. The Japanese are no longer what they used to be, neither Mercedes nor any other.
I remember when this engine first came out. I had recently stopped driving my 3 pot 1991 Geo Metro and thought the idea of a small car with a 3 cylinder and a manual was not so bad. Then I looked at that wet timing belt and the amount of power they were trying to get from a 1 liter (about 2.5x that of the Suzuki 1.0 in the Metro) and knew that it would be a bad idea. I bought a new 2015 Prius C instead and it's been a great transportation appliance (if a bit unlovable). In 8 years and 142,000 miles, all that has failed is the A/C compressor (under warranty) and the 12 volt battery. With the Fiesta/ Focus/ Ecosport, they had bad engines and even worse transmissions, as well as poor fuel economy. If you want a good small car, you buy a Toyota or a Honda. Anything else just won't hold up.
And the funny part is, Yamaha gets 118hp out of an 890cc 3 banger with no turbo and that engine is known to be bulletproof. Of course it's in a motorcycle, not a car, but still MCs do some things that you'd never do on a car engine, like use the engine oil to also lubricate the transmission, clutch and stator, and also rev to 11k RPM and make most of your power at over 6k rpm.
@@mrvwbug4423 car manufactures cut corners. They aren't as worried about a large gathering showing up to tell everyone how bad the product is.
Well....I just turned 100.000 miles on my 2017 Hyundai Elantra, with 0 repairs, and 0 issues. It runs smooth and quiet, uses no oil between 3000 mile changes. Even the brake pads are original, and again last week when having the tires rotated, I was told they are still good!! My 2 previous kias were also excellent.
@@mrvwbug4423 they built the V-6 SHO for Ford back in the day. A triple sho would be nice. But this. No key way? Oiled belt?
The 5 car fleet of delivery Fiestas we had at one of my jobs….. 3 transmissions failed. My boss replaced each of them with a Prius
Thanks for the Video, as a technician who retired from the Ford Dealership in 2003 I can only imagine the aggravation of doing this in the car.
As a Pinto survivor I got so much pleasure to see inside the worst 3cyl engine design. Thanks Eric.
I have a 2015 Fiesta with this engine, remaped to 160hp and 250Nm, with some mods, and it runs fine and like new after 130k km. I hope I'll keep it for some more years still. It is light, fun to drive and really economical when needed.
From what I've seen, these little engines are very sensitive to maintenance indeed. The correct oil must be used, it should be changed regularly and it has to be the correct specification and viscosity.
They are good little engines, but they need proper care.
Thank you for your video. It was a lot of fun! Specially hearing that turbocharger spooling. Cheers
I had no idea these had 3cyl engines. Granted I never bothered to look - never thought these were nice vehicles, but this was quite neat to see. If you are able to find one, it would be cool to see an M132 engine out of a 451 chassis smart car - another 3cyl that have their fair share of compression issues. Take care, eric!
I bought a brand new 1987 Yugo with a 1.1 liter 4 cylinder NON fuel injected, NON turbocharged, 4 speed stick. I got 30 MPG city, 40 MPG highway and once got 50 MPG highway with a consistent tail wind pushing basically an old style Fiat 500 redesigned by the Frankenstein body works.
Thank you for your videos, I don't have an automotive background and you help with getting ready to try some engine repairs I might not have. So many different engine manufacturers tear downs gives me confidence in what vehicles I own lasting for many years.
I love this channel, and what a likable guy he is!
Great stuff as always!
Thanks for the video! To all Ecoboost 1.0 owners. Never use other oil than in specification. Because of chemical reaction with the oil pump and timing belts Even a small add on of wrong oil can destroy the belts.
I'd say this could have been the starting result of failure. Standard oil may not have been suitable for this engine setup.
Why??
It’s just a cheap car motor,
But it requires exotic car maintenance!
That’s silly!!!!
As a Ford man, shame on ford!!!
For this pos!!!
@@metalted6128Good point, but at the end, you gotta follow the guidelines. The problem is a bunch of engineers trying to reinvent the wheel and complicating shit.
I would think most of those "oil additives " would do a number on the belts...

The 1.0 3 cylinder ecoboost engine was available in the Ecosport, Focus, *and the Fiesta* in US. In the Fiesta it was decently quick since so light.
The owners of the ST variant of the Fiesta. We called them FiSTers.
I’ll see myself out now
@@TheMadTube The FiST used the 1.6 Ecoboost engine. Oddly enough, that same 1.6 EB engine and 6 speed manual combo was sold for a few years in the last gen Fusion. It was oddly slow and not that efficient. Weird.
Slap one of those GR corolla 3cly in the Ecosport and it will go flying.
You could get a 3 cylinder focus in the USA?!
@@ganzonomy yep.
I end up on one of these videos at 3am when I can’t sleep. Never fails
This gives me a greater appreciation for the rugged simplicity of my Geo Metro's engine.
I wondered if someone was going to mention those. One of my bosses had a little metro with a stick shift and the little 3 banger with two squirrels and a hamster for an engine. It had 275k miles on it. Crap power, burned a quart of oil a week and rattled like it was an old guy with Parkinson's but it was a trooper.
I learn soooo much from watching you tear these down!! After seeing this, I would NEVER buy a car or truck that had this kind of oil pump and timing drive! Come on Ford! Didn't you learn anything from the Pinto with the rubber band design in the engines!?! MAN!!!!!!
This is my first time watching an engine get completely taken apart. I learned a lot from this video and the size of the engine is as small as it gets. Also, great video. :)
Careful it can be addicting 😂

That's a fantastic engine, and the mirage gets no love despite being a wonderful little car for the money.

Timing chain isn't that uncommon, especially on turbo engines. Unfortunately, ford never got the memo that there are quieter timing chains now that are drowned out by the fuel injectors.
I had a 1.0 focus, i loved the little car. It got like 40 MPG highway and 30 city real world. It was a great little delivery car. Mine was a manual transmission so it was kinda fun to drive in a geo metro way. I eventually sold it after it started making a weird noise at idle. It had been to the dealer like 5 times at that point for oil leak issues and i never got a loaner car, so I just gave up on it. It still had some power train warranty on it when I sold it so if the new owner had an issue, they were covered.
my parents had an 88 civic hatch, really made me love light little cars. so fun to drive, and frankly you feel like youre doing 100 when you're going 45 anyways lol.
I had one too. Loved it. ‘16 Focus w/ 6 speed manual. Sold at ~100,000 miles. Car was basically flawless - just rust spots on rear wheel arches. 54 MPG was my best tank. Would have kept if it was AWD.
Had the 1.0 in a fiesta and it was 100k troublefree miles before being sold. Fun to drive in a little car.
I have a 2015 fiesta 1.0 trouble free even the duel clutch transmission is good, high way sits on about 3.8 4.0 litres/ 100klm, this are a good engine, as usual you need regular servicing
I don’t think the cam belt is a wet belt, the oil pump belt is.
Great video thanks! Glad I've got an old Focus with the 2.0L Mazda motor. No Belts or crappy turbos to blow up!
That 2L is indestructible, I had a 2007 mazda3 with the 5speed manual and the 2L, no matter what I did that thing refused to give up
My thoughts too. Ford was putting out better cars in the 2000's. I personally drove that 2.0L over 225k before I sold it. Sold it for a what? You guessed it, another Mazda. The only thing I don't like about the next gen Mazda engine (same on the 2.0L) is the lack of port injection (gotta manually clean those intake valves..... again). Funny when I hear people say that the Ford/Mazda collaboration was bad. They don't know what they're talking about. Ford had better rust prevention at that time (look at the Mazda 3's) and Mazda is the new Honda will their engine designs.
Had a 93 protege lx with the 1.8L DOHC that engine was a gem good low end torque and could be rung out to the 7000 RPM red line all day. It took a loose oil filter( yeah the first oil change that I didn't do myself)and running it out of oil to lame it. Then running it out of coolant to kill it.
I had a 2001 protege with the 1.6L and a 5-speed. Those 1.6 and 1.8's just couldn't be killed. Fantastic engines, super easy work on. Mazda killed them because they were way too good (plus the only power was if you had a manual and no one knows how to drive one anymore ..)
Couldn't believe what a fantastic engine this was to drive when it was launched, Still can't believe what a bad job they did making it reliable long term.
Thats ford for you, corner cutters is in their badge
This engine in the Fiesta is a riot. At least for a short while.
50,000miles is hardly long term
My modest contribution. I have a 100cv Cmax 1.0 ecoboost from the year 2014. I have always done maintenance at the official Ford service, once a year and every 10,000 or 12,000km. It now has 102,000 km with no problems. I changed the timing belt for prevention, it showed no signs of wear or cracks and the system looked pretty clean. Never had any coolant leaks or overheating. I don't know how long it will last in good condition, or if it will eventually break, but I know more people with higher mileage and no problems. I drive it calmly, respecting the warm-up times and letting the turbo cool down before turning off the engine. I always used specific oil for this engine. I am aware that other users have used non-specific oils or 5w30 resulting in broken belts without teeth. I hope it helps, although the designers and engineers made a serious mistake by leaving the belt submerged in oil and giving such a small engine so much power
Puoi elencare le precauzioni che prendi, per favore? Ad esempio, quanto tempo aspetti che il turbo si raffreddi?
120k in almost perfect condition. No wear. You have helped me to decide to keep my 46k for at least another 20k. Thanks.
They really didn't go through much effort to obfuscate how intensely they wanted the engines to fail rapidly. I'm surprised that this is not a consumer protection issue.
Agreed. Wet timing belts should be outlawed. What an abomination!
Mine lasted for 90000 miles and nearly 10 years before I heard of this issue and got rid of the car, now it’s someone else’s problem. 😀
I'd own another one in a heartbeat. Completely reliable if you do the oil changes early and use the right filter and oil. I drive over 40k miles a year and I'm an auto tech. So many people talking out their bums without any facts.
@@marvetheman The wet belt breaking up and clogging the oil pickup is a real issue affecting many cars and I just wasn’t prepared to risk it. I did do regular 5000 mile oil changes but the Ford oil was so expensive, whoops😁
@@marvetheman The facts are that it uses a belt for critical timing issues, and un-keyed sprockets to drive its oil pump. Regardless your claimed authority in all things mechanical, because someone paid you to obey some tabular data and get excited for more tabular data, the engineering is poor. Mechanics are not engineers, or they would claim to be engineers, along with the engineer paychecks.
Meanwhile, it doesn't take an engineer, nor even a mechanic, to know that these design choices are both risky and cost-saving... A double-positive, from a financial expert's point of view... Hence, massive - and warranted - skepticism.
...or at least, that's what my bum tells me.
Hi Eric, here in Europe we’ve a lot of these engine designs with wet timing belts, Ford and Peugeot have had, shared diesel engines in the past, a lot of failures. One could replace this with an after market kit for a chain driven system. Here in the Netherlands we’ve a lot of owners of a car from Stellantis (Peugeot, Citroën, Opel, Fiat, Jeep etc.) with the 1.2 Puretech engine, having broken engines because the wet belt is clogging the pickup screen of the oil pump. Fighting with consumer organisations for compensation for the repair bills. I think these engines found their way to the USA in Jeep products, if you wondered about the flaws in this Ford design, when you get your hands on these 1.2 3 cilinder Puretech engine, you’ll see there’s even worse.
But also the TFSI engines from VAG (VW, Audi etc.) with timing chains have had in the past their issues with excessive oil consumption and stretching chains.
A lot of repair shops have a decent living setting the design flaws and/or bad choices regarding material choices, straight. Thank you for your very entertaining and informative channel! Love it!
Fortunately, Fiat/Jeep/AlfaRomeo did not use the current version wet-belt-1.2L-Puretech engine from Stellantis. I've got one of these engine on my DS3. Full rebuilt needed at 90k km due to abnormal oil consumption (piston rings dead) : oil is burnt in engine but petrol also mix in oil, degrading the timing belt that ends to a oil-picker clog. Stellantis announced next version will have a chain instead of the belt and will be shared with Fiat and Jeep. That will solve the clogging issue but not the piston-ring wear then oil consumption one.
Timing gears... No belts or chains. That is what manufacturers should use in their engines. Like some of the Le Mans engines do actually. But we never gonna see that coming. It would not generate enough cost after the warranty. All of that crap for the sake of ''ecology''. Clown world.
@@elzariantlp4594 Let's hope they do it better this time. We've seen what the psa (stellantis now)/BMW co-operation led to ... "prince engine". It had a timing chain and also lots of issues. p.s. I had a citroen c-elysee 1.2 puretech atmospheric. Sold it at little over 6 years. Belt was still in good condition. I now have a citroen C4 with the 100hp version of the 1.2 puretech with turbo. I guess the turbo versions (100, 110, 130 and 155hp) are more prone to belt degradation because of more blow by caused by the higher cylinder pressure. Causing the oil to get more hostile to the belt. My original service interval of my c-elysee said 10y or 180K Km's for the timing belt interval. Later stellantis lowered this to 6y and 100K km. However, still lot's of them fail before that. I would suggest people to replace the oil much faster. Like every 7.5K Km. (that's what I will do). And I use the one they specified for this engine (tested for additives eg) Total ineo first quartz 0W30.
I had considered 1.0 TSI engines for my new car, but man am I glad I found this video. If something can be called "a bean counter delight", this is one of them. This has so many "dynamic smartness" built in... only the accountants will be happy.
VW 1.0 TSI is having a lot different design - much better timing belt solution is among them. So far it is less problematic than Ford 1.0 EB
I have had two 3 cylinder engined cars in my time has a drive one was my dad’s two stroke 1975 wartburg which was run like a turbine the second was my last car a vw polo 1.4 tdi diesel which was very torquey also very economical but a bit rough blowing 2.000 rpm I had the car for twelve years and it never missed a beat I tried it with 110.000 miles on the clock for my 2015 1.6 4 cylinder diesel Vauxhall Astra which is given my a average of 60 mpg on the motorway in sixth gear at 70mph 75 mpg it having the extra cylinder makes it run a lot smoother and also it’s very quiet I don’t think I would go back to 3 cylinder engine again or petrol car
@@bassmanjura yes my sons partner has a petrol vw polo 1.0 atomic and my son has a 1.2 diesel he loves driving her car because he got lazy and likes not having to manually change gears he also says her polo has plenty of power and delivers good mpg
completely different engine though. There's nothing wrong with a 1L turbo engine, it's Ford's design which is the problem
I'm an old school but very much educated mechanic and all around tech person. I'm 64 and have an A&P Fed lic and diesel lic along with decades old auto certs. I don't care what they make that belt out of to run in oil, it is still a belt running in oil. Yeah, I'm not on the level of an engineer but logic tells me that chains AND gears work better, last longer than any other type drive system. I work on industrial engines of smaller size up to 3.0 inline 4 cylinder. Take how Kubota has used GEARs on their timing system forever and they still make the longest lasting and trouble free engine in my line of work. We have GM industrial engines and Mitsubishi that use the dry belt BUT use an all aluminum head that the MFG says to just throw away at 5000 hours. That is an insane type of regular "maintenance" for an engine IMO 50 year experience of working on this stuff. Today's engineers have got MAD. IMO of course.
Two main failure modes for this engine are oil pump filter mesh blocking with degraded belt debris (like your example), prevented to the best of my knowledge by regular oil changes (more frequent than specified) and ensuring use of correct spec oil. Second failure mode is due to coolant loss and the fact that water temperature sensor can report "Normal" temperature even after fatal coolant loss and head gasket failure. I had a 1.0 Ecoboost fail with coolant loss overheating (just over 60,000M on the clock, in a Focus). I had brand new engine fitted free of charge by Ford. This was essentially due to this type of failure being caused by the design flaw of being unable indicate fatal coolant loss and overheating along with hose issues causing coolant loss in the first place. 1.6L Ecoboosts had a safety recall and a low coolant sensors fitted (with buzzer and light), due cracks in head potentialy causing a fire. Later 1.0L Ecoboosts have an engine block temp sensor to force engine into limp mode if temperature is excessive.
Seems to be a common thing on the smaller ecoboosts. I used to have a coworker with an Ecoboost Fusion and despite him also being a Ford tech who kept his car in very good shape, his car blew a head gasket on him.
Never had an ecoboost myself, although I did have the precursor to one. I used to have a Mazdaspeed 3, so it had what would become the Ecoboost 2.3. Never had any cooling system problems, although it did eventually get the timing chain rattle. And I changed the oil every 4000 miles or so.
And that wet timing belt design is just stupid. The worst of both worlds. I'm a Honda tech, so I have plenty of experience changing belts, mostly on J series V6s, but I've done a few older D and F series belts too. Those are nice and easy to take apart. I've also put chains in K engines due to stretching. It makes no sense to add the extra work to do a chain when you have the service interval of a belt. Plus it's much more suceptible to failure than a traditional belt or chain design as a result. It takes serious effort to make something THAT bad. How did that make more sense than just using simple plastic covers like most engines with timing belts use? Especially when it's certainly cost them a lot in warranty claims. Between this and the dual clutches that eat themselves, I don't trust any Ford made small car anymore. And I love compacts and subcompacts (I daily a Honda Fit, and I've owned multiple Honda Civics, 2 Nissan Sentras, a Ford Focus, a Toyota Corolla, a Toyota Tercel, a Dodge Neon, and a Geo Metro, all of which I had fun driving)
Yep they're also responsible for a few deaths due to said fires and when they caught fire, the central locking trapped the people in the vehicle, unable to get out. More than a few cases in Africa that made the news.
Thats a super spot on diagnosis of failure, all related to oil issues.
and. you MUST NOT use any other oil specifications other than recommended.. all otjer oils will dissolve the belt
@@bobl78omg!
I remember hearing about people from Ford flying this block in overhead baggage they were so proud of it.
It's a shame too, the engine could have had so much potential if these glaring issues were avoided. I've always been interested in what manufacturers can do to get power out of such small engines, it would have been nice to see more success from this design and ultimately more power.
That was the fuel pump bucket that fell out when you pulled the cams out. Fuel pump sits inside of it. Common failure point when people don't change their oil. Also the tensioner on the balance shaft was a problem for breaking. Just like what happened on this one. I never came across any at the dealer that had cylinder cracks.
I was wondering if that bucket had wear issues. The VW EA113 FSI motors used a bucket like that too, and it was pretty much routine maintenance to have to replace them
@@tally5k339 yeah I ran into a lot of "my friend up the road is a mechanic and changed my high pressure pump". But he never changed the bucket which was the initial problem. Wore a hole in it ate the camshaft and ruined the pump
@@BeardedFordTech usually the exact same story over here in VW land. Bucket would get worn through, leading to the cam and HPFP piston having a grudge match and destroying each other. It's funny how 2 manufacturers can make the exact same mistake, but I'm guessing the customers aren't as amused
@@tally5k339 I highly doubt they are amused as well. Most manufacturers all use a lot of the same design things but just call them different names.
Even if it's not fine always says
"Thats fine, I should have expected that" Confidence is a virtue
Used to drive a Focus with one of these in quite a lot. They're not fast, but they're certainly quick enough, particularly on a fun twisty road. I used to get about 40mpg (UK).It went for a "quick service" at Ford at about 40,000 miles with some interesting rattling noises on idle, and didn't come back for well over a month... pretty sure that was a new engine under warranty. A colleague of mine bought a Fiesta with the same engine a couple of years ago, he knew what he was getting into, so he factored in the cost of a new engine one day when he bought the car and just keeps that money set aside. He's not needed to spend it yet.
Oddly enough, as a Ford dealership technician since 2000, I have yet to see one of these gems. After doing countless phasers, chains and water pumps on 3.5s both NA and GTDI, along with 1.5 short block and 2.0 long block replacements, I have yet to come across one of these wet belt engines.
What are your thoughts on the 2.7?
Same my buddy has only seen one 10 in on any platform and it was for something unrelated to the engine....
@@mcallihan100 Other than the oil pan leaks that only seem to go away after a person fixes it, not much bad to say,
Just wait till you have to quote a timing belt. Nothing but endless discard bolts
@@mcallihan100 as already mentioned above, other than the oil leaking from the plastic oil pans, there's not much else to be said about them.
I love watching this guy take engines apart, but the rhyme in the first couple of minutes was awesome 😅
Yeah, noticed that too. I don't know if he planned that or if it was just serendipitous.
He's very witty, so I wouldn't put it past him
The thing with these engines, is they do run well. As long as you treat them as such.
Running the belt in oil is so-so, granted, but to be honest - most of them work just fine and live a long life.
They're particular about the coolant and oil they need, but other than that, they're decent little engines. Not the best, mind you, but by far not as bad as most people make them out to be.
