⚠️5k miles oil intervals for all modern engines is key. Timing chains, guides cylinder walls and crank journals etc last last considerably longer. I've and others have proved it in the motortrade ✅️
I found the video very optimistic, not depressing. If your voice helps them stop that ignorance in even the slightest way it is well placed optimism to think it is well worth trying.
You can blame the company(s), but ultimately this goes back to regulations from the governments, full of people who don't understand ANY of these engineering problems, demanding better and better emissions. 😒 They should have stopped pushing a long time ago, and just accepted the significant gains already achieved.
You are 100 percent right! It's Consumerism, Purposefully creating a product that Fails with the intent to force consumers to have to Buy More! Artificially creating industry financial security. Instead of a Product that you buy once every 25-50 years, you buy a product that you have to replace every few years. Even Lightbulb manufacturing has a Limit to the number of hours the Bulbs are allowed to last for the reason that they can keep making and selling them continuously. Yep, Evil, Dastardly Consumerism. And it has gotten worse and worse over the last 75 years. They don't even try to hide it it seems. I Love your Cannel Man! Awesome, Educational, and Informative!
and also .....but not only bmw , others do too ....BMW spared ONE ( 1 ) lid and gasket and moved to timing stuff to....the worst place to be for a timing chain , at the point where the most vibrations and inkonsistency occurs , at the clutch . and it makes it more expensive to maintain or change . sometimes engineers need a slap to the back of their heads .
Walking also means lower emissions which is a win for the planet so the automotive companies can be proud of that. "More Ford owners than any other brand walk to do daily activities which means that we, the Ford Motor Company, are helping to clean up the planet."
Polymer scientist here: All polymers have in common, that chemical, mechanical and thermal loading/aging are not independent but reinforce each other, leading to drastically accelerated aging/failure. It is not completely impossible to develop a wet timing belt, but: The materials used would be drastically more expensive and development and accurate lifetime predictions would be extremely complicated.
Ford should take notes from Honda lawnmower engines. Honda mower engine have had wet timing belts for years and I haven’t heard about any breaking. I’m sure a couple probably have broken but not nearly as much as ford
"Ford now makes" - you meant to say "Ford is required under threat of law." Ford would rather not make a 1.0L ecoboost. They have to because of draconian unrealistic governmental regulations and laws which require automakers to squeeze 1000mpg out of their engines on average because "saving the earth" or something while their campaigns are funded by green corporations and they personally have investments in electric car companies.
The Ford "Fox" 1.0 3 cylinder engine was introduced with a wet belt which worked without problems for many years. However, Ford wanted to introduce a new version of the engine, I think with cylinder deactivation. This put more load on the cam drive. The belt supplier was unable to develop an uprated belt within Ford's timetable so chain was used on the new version. Wet belt oil pump drives are more common than wet belt cam drives.
@@RandomAccessMemoryloss I dispute the information presented in this video. If I see some data proving that wet belts are prone to failure I'll change my view. Tons of blown engines are a myth. Many people are biased against belt drives - particularly in North America - a place where many car owners still think a pushrod engine is a good idea.
The continued use of wet belts despite the known drawbacks only reinforces the belief that modern cars are not being built for long-term reliability. Awesome job on this video. 👏👏👏
The manufacturers don’t care as the belts fail after the warranty is up. Then they can sell parts or entire engines and add to the bottom line. They figure (rightfully so) that buyers mostly buy another brand of vehicle whether they have had trouble or not, so why should they spend pennies to try to keep them as customers? It’s all in the actuary charts for them. Also, decent cars now last 10 years or more, so a frugal person will own, what, 5 new cars in a lifetime? Even less incentive to do the right thing for them.
@@blauer2551I had Two Pinto's and both were really reliable and easy to work on. The best one was the 2000cc engine in the '73 it actually had 5 main bearings in the block. Thats the same as most V-8 engines.
Engineer: uhhh wet belt would break down so much quicker Exec: yeah but it saves $10 per engine and makes us even more money per failure *fires engineer*
Well you see it's actually great that the car will fail quickly and the repair bill is gonna be astronomical, cause that will push suckers (us) to buy more cars
The motor manufacturers are trying to make these things the default petrol engine, in order to give petrol engines a bad name, so that they can push their awful electric milk floats on to the unsuspecting and gullible members of the car buying public. It's all a race to the bottom. Great video btw. 👍👍
We had a Ford Ecosport fail the wet belt at 19,000 miles. Fully Dealer serviced and under warranty. Service manager accidently slipped and said, "Oh, we have had a few of these this year"! We shopped for another vehicle without a wet belt!
I watched a teardown of the Eco boost engine with the rubber timing belt it was prematurely cracked with rubber particles in the pick up tube which caused the engine to fail the belt looked like an old timing belt you would find in a 06 Honda Accord that hasn’t been changed since new

I work in an automotive component supply company, the illusion that parts are tested prior to launch is a hark back to olden times. There’s a computer based modelling of lifetime stresses and then the bean counters force a launch and everybody crosses their fingers for the best. I’ve even seen defective product shipped before a solution was found to avoid late delivery penalties. The Japanese are the only ones with tight standards hence why I only drive Japanese cars.
I've worked in the automotive industry and you're correct, everything and that IS everything is driven by profit! I've been in meetings where a known problem is being discussed and the conclusion has been to leave it alone, fight any warranty claims and, if compensation is paid out it's still cheaper than a production line change.
@@mr.g167 Ford decided that it's cheaper to pay potenantial insurance compensation for people's deaths in car accidents than reshape their fuel tank so that there was no risk of explosion after being hit. Just google Ford Pinto & "enjoy".
Not everything is driven by profit... some of it is driven by pure stupidity, and most of it by politics wrapped in so called regulation and green initiative that is all but not green
@@markrowland1366 Yeah! Then the batteries bump a rock and you have to scrap them because the warning button popped off (warning that the battery might have swelled). Try searching for a clip that shows a KIA Ioniq in Canada being charged $60.000 for a new battery for just bumping a rock with the undercarriage! A very small rock, I might add.
I'm from Brazil, Yes we have middle age problems AND wet belts. I always recommend people to ask before purchasing a new car, if it has wet belt don't go any further. But most of people just choose cars by their design and comfort items
I am guilty myself. I was happy to buy a newly designed engine w the last car, i was proud to have checked. But besides that i did not dig any deeper. One would think people could compare more easily these days, but where can i find all that detailed info in 1 spot. Or is the answer to everything Honda or Toyota. ?
I bought a diesel with a timing belt because it was easier to maintain than a v6 with chains that would be an engine out repair. Better fuel mileage is nice but goes to higher maintenance cost. Love the exhaust brake though.
I owned an engine machine shop in California - lots of BMWs. I love them! Made a TON of money on BMW. When the belt or chain fails on a normal engine, the valves hit the piston (some "non-interference" engines don't, but most do), the valve is bent and the valve guides are ruined. So you cut out the valves , remove and replace the guides, hone them to fit do the other normal machine work ( machine the valve seats that are serviceable, replace seats that were damaged, deck the head, etc) and then it's good as new. With a BMW, the piston hits the valve and it breaks the overhead cam saddles right out of the head castings! We had tooling (custom designed and made) that allowed us to weld up the heads to form new saddles, which we would then re-machine. It was still cheaper for the Customer than buying a new head from BMW, and our head was stronger. The Customer gets back on the road with a lower cost, and I make money. It was so lucrative that I kept various BMW heads rebuilt and ready to go on the shelf. There was always demand! The workmanship from BMW was beautiful... but the engineering wasn't.
@@supergeekjay That is not true at all clown. The Wastegate is removable with 2 bolts. You can replace the actuator alone without replacing the entire turbocharger on any turbo made from BMW or VW. The only person who would tell you otherwise is a shop attempting to scam you. The wastegate/actuator is only $200. People like you need to never touch a wrench again.
Lexus also have interference engines. If the belt/chain snaps, the valves hit the pistons and destroy the entire engine. 80% of engines made by ALL manufacturers will do this and are interference. Where the hell is your shop? Facebook Marketplace? Jesus Christ. This is not a BMW only issue. It is called Interference vs. Non-Interference.
Gone are the days where BMW are brick solid and can cover a million Mile without much fuss..nowadays it is all just that :$how off $how off and more of it
I'm am an automotive metallurgical engineer and a lot of my work engine R&D including both the specification side and the wear and failure analysis side. I have never witnessed a conversation that involved intentionally reducing the service life or reliability of any engine component, but I have been part of many conversations where my push (or the powertrain engineers' push) for more durable or reliable components got shot down on cost limitations. Management ALWAYS asks for more reliable engines, but they often set cost as a higher priority, and they almost always set fuel efficiency and emissions as the top priorities. Yes, the customer wants to pay for a reliable engine, but governments are forcing us to shave every tenth of a percent on both fuel efficiency and emissions. Automakers get fined hundreds of millions of dollars for selling customers the powerful, reliable engines they want instead of the 1% cleaner, 1% more efficient engines that sacrifice everything the customers want.
I don't believe higher management would ever disseminate or leave any proof that they would request engineers build less reliable engines. So of course they would use other tactics to reach the same result, such as reducing costs. So it makes sense you wouldn't hear about it
@@durragas4671 I've been involved in conversations that started with "what is the cheapest plastic we can make this part of" when nobody at that point in the design process knew what were the requirements for that part or if indeed plastic was suitable at all for that specific application.
I agree that the government is more responsible (rules, regulation and fines) for this than the automakers. Still the companies bean counters are to blame also.
That's because governments wanted the internal combustion engine gone, or severely limited decades ago. It all began with (over here) ridiculously high taxes on fuels. And the car manufacturers did not want to comply and kept on going with old tech (combustion engines). That had to clash at some point, and the consumer is the one paying the bill.
As an ex-ford tech, we replaced quite a few transit custom engines due to wet belt failure at around 180k kms, pretty consistently. They would just rip teeth off the belt.
@neilasd3043 Did it really? The last car we had with a dry belt had it replaced at 160KKM as preventive maintenance. It was still in good condition. Not to mention that the job is a lot less labour intensive and therefore cheaper.
@@mipmipmipmipmip-v5x Failing belt tensioners aren't any better. We had to replace like 3 alternators and the batteries (and the tensioner) a while back in our garage after one of the auxiliary belt tensioners locked up on a bus. But hey, at least they fail quietly :^)
Even with all the data proving that wet belts are a bad idea, yet car manufacturers continued to use it, in my mind is further proof that most cars nowadays are only being built to outlast the warranty period. The warranty period might as well be the guaranteed 'lifetime of the engine/car' at this point.
That's how warranties work in every industry. Any failure during the warranty period is considered _premature failure,_ but if it dies one day after the warranty period it is _past its expected lifespan._ The manufacturer doesn't want the product to fail under warranty because then they pay for it out of pocket, but they don't want it to last much longer than the warranty either because well... Any failure after the warranty period is _past its expected lifespan_ so why make something that works _too well_
@@Creepus_Explodus This is actually wrong. Many cars are leased out to corporations and the leasing company wants good residuals, which means that they must not be perceived as being unreliable when sold second hand. Modern cars are expected to be reliable for 6 years, i.e. twice the typical lease. Over here Mercedes dealers will buy cars under 6 years old. Go over...well, I know someone who foolishly bought an Audi TT when she retired intending to keep it. After 6 years it started to get expensive and she then found out what the value was. No more Audis, the trade in didn't cover a used Polo.
That one percent fuel saving would go straight out the window as soon as the engine goes into rich mode because of engine knock. So Infact there is no saving at all, just more expense. I must say this channel is one of the best, if not the best automotive channel on RUclips. Great work.
Same with the EGR lie! Reducing NOX with feeding the engine junk meant less of a percentage of nox at a higher fuel consumption. Burn more fuel = more profit for the industry with total nox actually gone up!
Certainly the Ford 1l ecoboosts have long been known to get nowhere near their cited fuel economy figures and I would not be remotely surprised if that's because they end up running rich because of the normal driving conditions they find themselves in
"I'm a fan of objectivity and rationality." A-effing-men, brother, speak it! This is the best-explained, best-reasoned takedown of the industry's painfully obvious wet belt scam. Absolutely beautiful.
They did it to flamboozle regulators: the 1% savings was all about milage gains [real or imagined]. The fact it costs consumers 1000x to maintain vs what gets saved at the pump? Not a concern of CAFE standards, or the politicians pretending they know anything about engineering or economics.
It's not a scam for profit. It's to satisfy the insane CAFE regs that are pushed by idiots that think a good EPA rating is all that matters. Look at what they've done to diesels. Pre EGR and DEF diesels were known for going a million miles. Now that's a pipe dream. They've been made so "clean" that you have to replace them or a number of components in less than a quarter of that service life, and producing a new vehicle is a way bigger generator of pollution than running the vehicle. It's a scam alright, but the green in it isn't about money it's about the morons thinking that EVs, solar, and wind are going to save us. It's all shortsighted stupidity.
I have a 1.0 civic turbo from 2020 that has an oil wet belt and it changes the oil every 9000km and the belt every 120000km. I am at 80000km and no problems yet related to that but your video is very cool and informative I am never buying a car again without carefully investigating more on its engine. Thanks!
I'm an automotive technician and I was working on a 2019 Ford ecotec it came in with low oil pressure. I found that belt material from the belt driven oil pump Had plugged the oil pickup tube. The vehicle only had 60 thousand miles
I work in the auto industry and can 100% tell you, this sort of thing is absolutely intentional. If they could get away with it, they would make them even worse so they could make money. As long as it survives the warranty duration, that is all they care about. Anything after that is profit.
I worked in the engine rebuilding trade in the 70s. Many teardowns revealed engines in serviceable condition except for the failure of the iron camshaft timing gear with molded plastic / nylon teeth around the perimeter.. I guess the idea was to make engine quieter, and it was great until the teeth crumbled.
Having worked with engineers, this is most likely gross incompetence rather than malice. The engineers know it's a bad idea, but the higher ups think they know better than the engineers, and guess who signs the paychecks. It's not designed to force you to have to repair it, it's just stupidity running the engineering department rather than actual engineers.
@@Bitterrootbackroads That happened to my 1976 Ford Torino (351 Windsor). IIRC the camshaft timing gear was aluminum with the nylon teeth. Fortunately, it jumped timing in my driveway and fixing it involved merely replacing the timing set with all-metal gears, lining up the marks, and putting it back together. That engine ran for many more miles...
@@richardmillhousenixonand here is the explanation why Boeing is so bad at the moment. Yes you need to make sure you can make money. But you also need to make sure that the product you make is not a death trap.
I can't recall hearing the timing chain on any engine, ever. Even my dad's Cadillacs, which were overall very quiet, had enough other noises going on that you couldn't hear the timing chain.
Great video - absolutely loved your description of the problem and its likely driver. I am definitely taking your advice and avoiding wet belt engines. I currently drive a GM Mokka with the 1.4T Petrol engine, and I change the oil every six months or so (for me, that's about 5k miles). I shall be changing soon to something like a Nissan Qashqai.
This is amazing timing, a week ago I was showing my best friend a wet belt in a Ford EcoBoost. He thought it was insane as well. The thing is a timing chain in an engine with regular oil changes can often outlast the car. I have an GMC Atlas 4.2 and it has over 330,000km on the original timing chain and I'm still driving it, let's see your wet belt do that. 🙄
A Ford dealer here in Germany quoted me 2850€ (roughly 3000 $) for a Timingbelt change on my 1.0 Ecoboost. I have 10 years of fixing all sorts of vehicles under my belt, but theres just no way i could do that job on the Parking lot of my appartment. You need an entire Briefcase of special tools AND pull appart half of the Engine (best would be to just rip the engine out at that point), for a job the takes 1 1/2 hours on a old VW/ Opel/ French car. (2 hours if knock one back with the bois while i`m at it) Not talking about the gigantic mess of oil or the "shit, now i need this specific part from the dealer i forgot to buy/ broke"- moment. Hell, doing a CLUTCH-job on most cars is easier and faster then this shit.
That quote is ridiculous. Presumably that's an official Ford dealer? I drive Fords for a very good reason, and that's because they are good value for money, reliable, and cheap to service and fix. But your quote totally undermines that concept of value for money for the customer. Surely, you could get a better quote than that if you go to a good franchise dealer, or even a specialist mechanic shop with a good reputation? One could buy an entire second hand car with that kind of money.
I've seen a picture of a Ford engine that has the oil pump driven by a wet belt, that goes around the crank, so you'd need to remove the crank to replace the belt, a belt that is emersed in viscous oil, wedging itself between the pulley and belt. Mental.
Do not apologise for, or ever shy away from your comments towards the end of this video! I am certain that many people feel exactly the same and have had enough. You are absolutely right that too many times, people do not do the right thing. They do not do the human thing in the way they act towards others. Perversely though in the case of wet belts, they are actually being human by demonstrating the worst of human traits…. greed; personal benefit at the cost of everyone else. I am a mechanical engineer and the owner of a wet belt Ford Transit. Such conflict and 10,000km oil changes 😮
Here again, yet another proof that taking YHWH out of the public eye leads directly to Godless behaviors: greed, selfishness, evil. Get God back in your life and the lives of your family and friends
Hi man, during the last few days I saw few videos of yours and I'd like to thank you for doing what you do. Your excellent videos are well paced, clear, consice, yet comprehensive enough, such that even a guy like me, which have very little knowledge about everyrhing mechanic, let alone engines, can get the point. I also like your production style, the graphics and the lack of cynicism. Very good work.
Love your content, man. I've been watching for years, and I am so fucking glad that you haven't quit despite not getting nearly as much attention from the algorithm as you deserve. As car enthusiast and somebody who intends to attend university for mechanical engineering, this content being so unique (I've never even heard of a lot of these topics you bring up) and so easily digestible will not have only been a key role in making me knowledgeable, but also will have been a major reason for me even beginning in the first place. This content is consistently interesting, thought-provoking, and explained in a way that made young me able to understand. Without this channel, there would be A LOT less content to fuel my curiosity and inform me. Who knows if I'd even care for engineering without you. For that, I am so grateful. And, when I finally get some money once I'm old enough to get a job, I fully intend to support this channel and your work for all of the amazing things you've done for me. Good luck in all your ventures, D4A, and thank you for everything.
D4A, another great video my friend! I'm a motor mechanic, an old motor mechanic. These kinds of things pop up from time to time and have done over the years. What HAS changed, is that the manufacturers don't care like they used to. They used to care that they had released an inferior product and would work hard to make the replacement better. An example on a personal note, I owned a Spanish built D40 Nissan Navara 2.5 diesel. They became renowned for timing chain failures in the Renault engine after using fine pitch chains and plastic guides to reduce engine noise. (Mine was replaced by Nissan as a 'good will' warranty claim at 113,000km). I now own a D23 Navara and it says in the owners handbook, timing chain replacement due at 300,000km. If that chain fails before then, Nissan will need to be very clear why it has, and why I should be responsible for replacing it.
I agree that the attitude of manufactures have gone downhill to our detriment. It appears their strategy has changed to accommodate this: they are selling on features more and more, capitalizing on the current popularity of high tec electronic gadgets. Their advertising pushes all the convenience features indoctrinating the younger generations that they deserve to be pampered by their vehicle. Does anyone repair their own vehicle anymore ??? The situation is made worse by the ridiculous extent fuel mileage regulatory requirements have pushed. Regulations are so far past the point of diminishing returns the life cycle cost of hardware is probably greater than the fuel cost improvement. The auto manufacturers actually like this, as it makes the service lifetime shorter for all manufactures !
The engine in my 1943 Farmall tractor has timing gears and has been running reliably for 81 years. Yeah, maybe could use a ring job, but still basically bulletproof.
Several Honda motorcycle models were having reliability issues in the late 70's / early 80's with cam chains (& tensioners/guides) so, probably in desperation as their reputation was taking a hit, introduced gear driven cam shafts on their VFR400 & 750 V-fours & CBR 400 in-line 4 cyl's. Reliability & longevity issues were solved.
@@wullie3xv923 Yes! this exactly. Sure they're heavier and more expensive and noisier, but I love the gear whine on my VFR, sounds like a little supercharger! aaaaand I never need to replace a tensioner or chain. seen examples with a 150K on them and the valve clearances are still in spec.

@@gillesgirard7812 - ALL the automakers went to the nylon covered timing gears/sprockets in 1960s... supposedly for noise... maybe for known shorter life... but the low cost replacements can be all metal... however, my '77 and '85 Iron Dukes still have their nylon gears...

We had a Vauxhall Grandland and it's was on it's 3rd belt in 46k miles. The first one began degrading and was blocking the oil system. We change that at 24k miles and had to flush the oil system. We replaced the 2nd belt at 43k miles with 19k miles on the belt and it had also began to degrade requiring another flush of the oil system. Our Vauxhall garage is now recommending changing them every 15k miles. We sold it asap...
I'm currently researching which car to get when our Hyundai i30 needs replacing, and called into a Vauxhall garage yesterday, where there were several Grandlands and Crosslands. As far as I could tell, these huge vehicles all had 1.2l petrol engines, turbocharged, but tiny nonetheless. We definitely won't be buying anything with a wet belt, or a tiny engine.

Honda had a change of heart during the last few model years of the civic. The K20C2 engine used in the civic sedan and hatch is naturally aspirated, port injected, uses a timing chain, and is offered with a 6-speed manual. Doesn't make much power but it's almost bulletproof
In 2024, creating an engine with similar functionality to the original K series they released 24 years ago is only impressive because everyone else is making such overly complicated disposable junk nowadays.
@@averyalexander2303 In 2024 using such engine is blatant stupidity, since it offeres worse performance, worse fuel efficiency and worse noise, vibrations and harshness than competition. It MIGHT be more reliable for customers in used car segment, however it offeres 0 (zero) advantages for the customers that... actually buy these cars.
As someone who is working in the automotive industry, I can say with confidence that this is probably gross incompetence rather than malice. Our team is currently also doing thiings that we would have solved differently, but those that decide are not engineers. It is management and sales. They hear about a technology at a convention and force engineering to implement it against their will. Sometimes they sell it before we even heard about it. It was probably like that at Ford, it was certainly like that at VW, Opel.. after somone from sales heard the 1% fuel savings number.
Same in software engineering. Some idiot promises and sells high heaven with 'Tec X', then they come to the software architects/programmers "So you need to do this, because I sold it and that is our most profitable deal in years."
What you are describing there is in my opinion malice by all accounts. Hearing the engineer say this is detrimental and doing it anyway sounds like malice.
I worked as an automotive prototyping technician from the 80s to 2014 , for five different manufacturers : I saw the skill level of designers decrease year after year ...

This was definitely done on purpose and the purpuse is to fail. Everything is engineered to fail nowadays because manufacturers don't make any money on things that last forever. They make money selling new stuff and selling spare parts.
I’ve just had to take the front end off my Renault master , radiator out and remove starter motor to get at the hole to screw the timing pin in to lock the crankshaft to change the timing chain, and remove top engine mount 🤷 engineers now come on a dingy 😂

Thanks for sharing this. I only found out that wet belts were a thing about a year ago, couldn't believe that anyone could think that this was a good idea. Personally I think that OEM's should be held accountable under consumer legislation and be required to offer a chain drive retrofit at cost and with free installation. To me the oil pump drives should always have the most durable and reliable drive technology of any drive within an engine, to choose a wet belt is guarantee of catastrophic engine failure at some point in the life of that engine, unless you do oil changes at 5000 km AND you are very lucky. MADNESS!
Honda also decided to use wet timing belt in Honda City 1.0 turbo which is one of the best selling here in Thailand. Timing belt de-lamination has becoming commonly found problem in this model as it older. This problem costs a lots money from the users since the pieces of de-laminated belt usually clogged VTEC solenoid strainer or engine oil pump strainer which caused oil starvation problem and broke the engine. BTW, Thank you for good video!

Great video. Brilliant explanation, easily understood and I'm completely amazed these manufactures are still producing these and not recalling all their engines to refit a decent timng system.
Thanks for the video. Many people owning these cars aren't aware of the wet belt peculiarities. PSA reverted to timing chains but kept the wet belt in the oil pump.
Regulatory Powers sadly can't keep up with changes or updates in the industry, so sometimes it's the customer who need to force changes for the better, by voting with its wallet. But the regular consumer isn't qualified enough to overview things like this. That's the reason why unbiased reviewers and journalists like here on youtube are so important.
In most cases consumers are just to damn lazy to get an overview, they will just buy any ugly crossover with ridiculously large wheels. I'm still baffled how people will buy a >30k€ car without searching google for 5 minutes, take the Peugeot PureTech engine for instance, they have been notorious for belt failure for the last 12 years yet people will buy it without any hesitation or personal research.
My relatives had a Fiesta where the timing belt broke at 48,000km. Vehicle was 4 years old, maintenance only at the dealer. After a bit of back and forth it went under warranty, but they then sold the car and bought an older Toyota Yaris.
This is simply the best RUclips post I have seen. Every point you make is spot on and makes complete sense. Thank you for this although it was too late for my son's 2017 Fiesta Ecoboost which died due to oil starvation because of this "feature" in 2023. The only saving grace from this was that he got a good scrap valuation due to the demand for second hand prices for ECUs.
Our company had a fleet of vehicles from a rental company who managed the fleet, and most cars had engines with wet belts. There were numerous cases of engine failure with 60K km because of debris from the wear of the belt clogging the oil ducts, pumps and so on. To make it worse, the maintenance was performed by third party workshops (not the car brand workshops) selected by the rental company, and the oil approved by the rental company was not the correct specification as the car's manual...
@@AndriusKamarauskas The rental company had to replace engines on some cars, but eventually due to several other problems with maintenance of that car model, the management at my company demanded an action to avoid lost time and ensure safety for the employees, then they anticipated the renewal of the contract to replace the fleet with another model (fortunately, the new car uses timing chain instead)
12:50 Our Insignia gave us the "Stop Engine Immediately" message on a freezing cold morning start. It was the pump 'O' ring. We got it replaced straight away before damage could be done.
You're one of the very few owners to recognize the emergency convaid by that simple warning light. Most people would put time considerations ahead of the state of their vehicle...
Sell it,, don't waste time with that car. Not only the O-ring will fail, but also the oil pump and many more. Remove it till it still works, those are nightmare engine to rebuild after that and with big chance of failing again.
Please remember that most of those engines were mostly developed before the diesel gate. At this time, European emissions standards were hitting hard, with regular and stringent updates, even if some cheated or interpreted it in some edgy ways. Bean counting design has been applied to so many engines back then, especially on the emission side of the spectrum. Also, the market was more lively than it is today, and all manufacturers were trying to avoid echoing those development costs to the customer. I worked as a machining engineer in camshaft/crankshaft manufacturing in the late 2010s. We had to cope with some design updates for like, -0,2 grams of CO2 per km. Now, imagine if you follow the same search for minimal gains for a totally new design. If a design project leader was able to demonstrate he could maintain the same engine on the market for the next 2 or 3 euro emission updates, he would most certainly take the cake. So they generally stacked cheap, unproven, quick to develop solutions to obtain their results, without thinking of the aftermath. Those consumption reductions were never meant to be perceived by the consumer, their intent was to develop a new euro compliant engine as cheaply as possible, that could be sold for many years without much updates, no matter the long term reliability. Small downsized 3 cylinders are just a plain example of their own. What worries me the most is that they somehow have to compensate back the emission gains another way around if they bring back more reliable solutions. Any ICE update or ground-up design is incredibly expensive for a manufacturer, and nowadays this will most definitely impact the selling cost.
in norway we have cold winter's. and a lot of ppl by these small cars to do short trips. the engines never get hot and the fuel dilution gets to be high. i have NOT seen a 1.2 PSA engine make it to 60k km without failure in those conditions. The belt start to fall apart and then clog the oil pickup and the engine is run 10-15k km on low oil pressure before the lamp comes and and ask you to stop. by then the damage is done.
Ford's engineers come from the accounting department. Italian and French engineers are just stupid. Ferrari's engines for example were designed by idiots. Every single part is terribly designed and put in awful places. You can't even access the crankshaft without taking the entire engine apart. I'd be ashamed to to sign my name on those projects if I was them.
@fladave99 "This growth can be attributed to sales of full and mild hybrids, which grew by 21% in Q2 2024 vs. Q2 2023. Hybrid sales growth was particularly apparent in France (40%) and Spain (27%). The hybrid market share in the EU top 5 now stands at 32%, meaning that almost one in three vehicles now sold in the region are hybrids."
The process you describe at 10:40 is exactly what happened to a friend of mine who had purchased a very young Ford Focus estate 1 litre. It had less than 60.000 km on the clock when a blocked oil strainer left them stranded. The engine survived but the cost of cleaning up, replacing the belt was close to 2k, on a car they had paid close to 30k for a little over a year earlier….
I heard in the medias that those engines were having issues, and thought that it was probably badly maintained vehicules, or just a bunch of people with bad luck. It was very interesting to hear the actual technical explanation behind that.
When I first heard about a wet belt in an engine my immediate reaction was - what a stupid idea. Thanks for validating my reaction. Excellent analysis.
We can conclude that engineering exists to make an engine last 500k miles. Engineers now focus solely on timing big failures just outside the warranty expiration. The closer they get to the expiration date, the better the engineering job. Kudos to the folks at BMW - you are at the head of the class!! 👊
...engineering USED TO exist to make an engine last 500k... Yep, now they want things just barely good enough to outlast warranty, aka planned obsolescence.
Don’t assume malice when incompetence is a good explanation. A lot of the oldtime grease-under-the-fingernails engineers are gone and companies are stuck with CAD monkeys that couldn’t even change the oil in their lawnmowers.
😂yes....Original Lexus LS400 engine. Pure silk designed to basically run forever, for instance. Or the original red block Volvo with a timing gear/sprocket....
I am working daily on the 1.2T Pure Tech from Peugeot. It is absolute shit. We had more than 100 instances of premature belt replacement in 2023. And by premature I dont mean like you said around 100k km, I mean 35-50k km. The earliest was around 20k if I remember correctly. Peugot has in time done four things to combat this: The service interval was reduced from 30.000km to 20.000km, the belt interval was reduced to 60.000km, checking the belt is now a point on the yearly insepaction, with the tool you showed, the wet belt design was replaced by a chain in late '23.
Had this engine, serviced by book at the dealership. Even had the belt replaced prematurely due to cracking. Still, at 110k km the engine was done due to running dry (pieces of rubber blocked the oil pathways). THe dealer was quite frank by telling me they could in theory get me a new short block and fix it but in practice I should get rid of the car and get something else because the engine is total crap made for 100-150kkm. It was at time when they stopped selling diesels in EU and only had this engine in their lineup so they basically told me to buy car from someone else.
That's correct, but the 1.2 TCe is also known for segmentation issues, which also catastrophically broke the engine early. At least they fairly quickly fixed it around the end of 2016 and moved on to the pretty good 1.3 TCe after 2017.
@@AlexisyFR In our fleet of company and personal cars/vans we have; 1.5dci, 1.6dci x3, 2.0dci, 2.5dci x2, 1,2D7F and 1.3Tce from Renault, also we have few Nissan vehicules and had some VWs. With good maintenance they serve us quite well. Only 1.5dci, 2.5dci and old D7F have dry timing belts but that is not a problem, they are not sensitive.
The rant at the end was my favourite part. I feel that from the bottom of my heart too, just the crushing feeling of how much further we could be or could have become if it all wasn't in the quest for squeezing every last dollar and the very soul.
As a species we could be EASY 50-75yrs more advanced in society tech education and makong every humans life better. But nope profits greed and short sightedness is how we operate. Only when nature/the universe finally wrecks us will we maybe change. Sadly it may be too late and our species may not make it.
My ford Ranger 2.0 Bi-turbo use this timing belt belt dip in oil engine. The manual said to replace it at 240,000Km but I heard that a large number truck of the same model have issue of timing belt break before reaching 200,000Km. So, on my 165,000Km oil change, I decided to have the timing belt change as well. And sure enough, the old timing belt the coms out of my truck had a lot of crack on its rubber. My mechanic told me I made the right called, the original timing belt wouldn't last another 1000Km.
My neighbour just bought a new Citroen C4 with a 3-cylinder wet-belt engine and it runs so hot that the tops of the front wings become almost too hot to touch. His new car replaces another wet-belt C4 for which he was quoted £1200 to replace the belt, and yet he bought another. He's a Citroen devotee since the days when the Peugeot Citreon made pretty good diesels.
Ah yes. 2.0 HDi. 136kms (or 110 in 8v head). 5L/100Km and it does over 500k kms without much problems. And they can be easly remapped (136km -> 170km) with even more fuel saving. I was able to get... 4.3L/100kms doing constant 90km/h.
I've reached this video after I did a relatively random timing belt check on my 1.2 Puretech equipped Citroen C3 Aircross before a 200km trip and found that it had formed cracks. That belt is no older than about 50-60.000km in an engine that receives full synthetic oil on a relatively regular basis but that does see a lot of stop and go traffic. An absolutely terrible idea for any engine but especially for a city car. Thank you for making this video.
One of the worst things with the wet belt on the Transit van is it sheds particles which block the oil feed to the vacuum pump - the result of this is the vehicle brakes fail when you don't expect it. One of my neighbours nearly had a very bad accident when trying to stop.
@@JHe-f9t The vacuum pump on the transit has a oil inlet with a hole about 1mm in diameter. Doesn't take much to clog it - then the pump stops working and has to be replaced.
@@AndyFletcherX31So ford in their infinite wisdom took an existing vacuum system that has worked for forever that has no moving parts and is free and put in a vacuum pump?! And it's $500 to replace?! And I thought ford from the early 2000s were bad...
@user-yu8ur9yi9e turbo engines don't make consistent vacuum, the intake is pressurized and the vaccum infront of the turbo isnt enough on even gas engines now. So they fit mechanical vacuum pumps to run the power brake booster no matter the engine boost level, this isn't a ford thing it's a all turbo engine thing. Diesels have had them forever and now gas engines have them.
I have owned two Ford products, a Lincoln Continental and an E-150 van. While both had steel oil pans, they apparently were painted with a coating which allowed road salt and moisture to work it's way under and eat through the pan, causing the oil to leak out. I repaired each in turn with a material from an auto parts store which reduced the leaks to an occasional drip and got rid of the vehicles. Part of the price we pay to live in the rust belt Thanks, Ford
I used to work for a major European car manufacturer. They released a new engine in the early 2000's, which had a timing chain that wasn't designed to be replaced. Instead, I was told the engine was designed for 100,000 miles (with regular scheduled servicing) and anything after that was a bonus. The point is, for any manufacturer to keep selling cars, they don't want long lasting cars that keep on going.
@@Okurka. It really wasn't. Basically every EA827 VW motor except for the G40/G60 would do 150k+ miles no problem. Which is also why they were available dirt cheap on junk yards for ages - VWs were scrapped because they rusted out, not due to engine wear.
Ford products are garbage this is one more reason why. Even if you wanted to drop the oil pan and clean the pickup tube the Oil pan are "single use" . Ford robs people blind and they would be out of business if they didn't have fleet accounts.
@@jmbpinto73eh, accessing the belt to change it is a pain in the behind, especially in modern cramped engine compartments, and particularly in small cars with even less space. Of course there's experience involved, and I'm not a mechanic, but let's just say I do not look forward to when my car will soon need its belt changed - and I believe I've heard from plenty mechanics that they don't like the clearance around modern engines' belts, either.
@@mnxs That's not a problem with the belts though, that's a universal problem with engines becoming more complex and compact. If you think a timing belt with bad access is bad, try a timing chain.
Agreed. My Camry has a non-interference engine. The timing belt snapped at 180,000 back in 2015. Belt was replaced for $500 and the car is still driving at 250,000.
Interference engines are more and more the standard type as they squeeze out another 1% in fuel economy. As this is the case, the vast majority of engines would have chains of the manufacturers cared. Honda uses only interference engines these days and went to chains when the numbers showed that customers were replacing heads prematurely. They care and make the best performing and most reliable engines on the planet. That’s a tough combination, but they manage to pull it off.
Exactly what I have been thinking since I heard Fords Ecobust motors were running their belts in oil. Just put in a much clearer and coherent manner than I ever could. Great video.
O-Rings are also made out of NBR or FPM (Viton) and very reliable against mineraoil. But in difference they are not so mechanical stressed and swelling is even good for proper sealing. Very interesting report as always from your channel.
Hah I thought bout buying a Mazda Cx3 but it was too cramped for me. Long story short I bought Ford Ecosport with 2.0 duratec(basically mazda engine xD) and 6f15 gearbox. Ohnestly the best combo for this small car and I would not touch ford 1.0 with 10m pole. It is kinda sad when fun cars are getting "short stick" of bad engine/trans combo.
16:42 the Honda 1.6 iDTEC uses a chain not a wet belt (you can even see the chain in the photo you used). It was the Honda 1.0L turbo 3 cylinder petrol engine (P10A2) which had the wet belt!
Was going to say this too, among the small displacement turbocharged engines, the 0.9tce from Renault must be one of the more reliable since it has a timing chain and multipoint injection, so less chance of admission carbon build up. Who knew old tech can still be good 😁
In 40 years driving front engined Porsches, I’ve changed dozens of belts, both cam and balance. A good belt was a dry belt - period. Those belts were a big deal to replace and tension properly and of course, interference engines. I got pretty damned good at it. If I could detect any sign of oil on those belts, I knew I had much bigger issues and that they were NOW issues.
@@finleymakee4850 Well, it took a second to parse your odd wording, but it looks like “only Porsches do not leak” which is close to true but old German cars all leak, which of course makes no sense.
You just did a great job of laying out the facts. As a retired mechanic it greatly disturbs me that the manufactures seem to not care once the garbage they produce is out of factory warranty (Ford Motor Company). Now also GM with their 3.0 liter Duramax Diesel that uses a wet belt to drive the engines oil pump. To replace this belt the transmission has to be removed! This is why we as consumers need to do a lot of research before buying. Your video is an important part of the information us consumers need to make an informed decision. Thank you.
honda came out with the GC160/GCV160 mower engines in the early 2000s, rubber timing belt that rode in the sump. I got out of the industry by 2012 but even to this day, I've never heard of one failing. Those were good little engines. After going through honda training school on them, they explained to us all these little things they had thought about. Like, for example, the choke lever had a nub made onto it so you could plug the fuel line with it. Everything was really designed as much as they could to make it easy to work on. I inquired about timing belt changes and while they did make the crankcase come apart in such a way you could change the belt, they said most would never need it, as it lasted the life of the engine. And, they were right, like I said, never saw one fail. Of course, Honda was also making riding lawnmowers with timing belt driven engines back in 1985, which is just insane haha.
10 years on the wet belt in my gx25. Crazy how good these things are. Regularly see them with 25 years on them on fbm. But i bet it has something to do with the hp:belt ratio. Probably much better on these than cars.
These are the best videos you could make IMO. Making people aware of the junk that's out there to avoid as well as manufacturers to avoid for their practices. I knew about the wet belt issue in some engines, but was not aware of how long it's been going on.
i work as a PSA mechanic and this problem with the 1.2 PureTech engines are a big problem at my workshop. alot of cars go under 100k km and still have cracking belts. also when the belt starts to crack the fibers in the belt starts getting loose and ends up in the oil pump and in turn the engine blows up because of no oil pressure. we have atleast 10-20 of these engines with broken belts/no compression sitting scrapped outside haha
6:23 cue my dad getting a €4300 bill because the vacuum pump of our B-Max (with the 1.0 EcoBoost) locked up and jumped the timing (and that's with a 25% discount because the bill already exceeded the market value of the car!)
Likewise with non servicable parts used in domestic appliances, parts that are 100% sure to fail just outside the warranty period. It's all very carefully planned. It's all down to profit margin.
@@gregorymalchuk272Yes, very hard agree. If you're unfamiliar, check out the "right to repair" movement. It started within the electronics sector (you know how modern cell phones can't even have their batteries replaced without what almost amounts to major surgery), but it's spread to other consumer products, especially technology-based.
Major appliances became shit in the 90s. t. washing machine enthusiast That said though, Bosch/Siemens is surprisingly willing to continue supporting even their ancient machines from the late 80s onwards. You can still buy parts directly from BSH. Take that, Miele.
Sadly it'll never happen. There's no money in it products that last. It makes me sad that there's so many greenwashed initiatives while at the same time, so many products are designed to be binned after 1-5 years. When I ran a business selling kit we designed and manufactured, we prided ourselves on the longevity and on going support for our products and built a reputation on it. It wasn't cheap though! It was great to see version 1.0 kit coming back for refurb 10 years after selling it...
Yeah. Always bought Zanussi front-loaders. When the drum-bearings failed, you could dismantle the outer drum and replace the bearings. Other manufacturers used a plastic outer drum, welded together at the factory.Don't know about our current one.
one thing that I find amazing is that f1 (pinnacle of motorsports engineering) is using timing GEARS instead of belts and chains for the last 20 years and no one even mentions it as a possibility to solve this problem once and for all.
There were engines made with timing gears, like the 3.0 liters diesel from VW used in the first generation of Tuareg. It basically never has to be serviced.
Super noisy and ineficient. Race cars usually have timing gears to be robust, but chains/belts are way more reliable in the long run because they make up for small changes im clearences and wear.
A lot of race car engineering is inappropriate for road car applications as the goals are so different. NVH, cost and long-term reliability being the obvious ones. As you can imagine it's a lot more difficult to tightly control the position and precision tooth form of a series of gears versus a few gears connected by a much more compliant chain/belt.
I agree the idea of wet timing belt is endlessly stupid. So many people told manufacturers it is a bad idea. Yet they still did it. Obviously for profit, but not only, because they were able to whitewash this stupid idea with ecology (while in fact it is not). Nevertheless, the problem is that we do not have enough competition on the car market (with the exception of Tesla and some of the chineese manufacturers, which bring other problems to the table). This is due to the fact that manufacturing entry level is exceptionally high and industry is over regulated. The second thing is, I am glad that there is a class action lawsuit against Stellantis for 1.2 Pure Tech, but other manufacturers should be sued as well. We need to bring back the consumer market by increasing the competition and increasing the consumer awareness - and this is something this great video does. Thank you!
Thanks for your honest and objective presentation. I've been a victim of failed timing belt in my old Honda Accord 1986 model several times then, I vowed never to buy any Car that uses belt anymore and I maintained my stance till date.
As a sixty-something ex-engineer i was dumbfounded that a welt belt was used in a colleagues engine (Ford 85K). Upon removing the head just about every valve was bent and an entire top end rebuild was necessary + some re-modelling of the top of the pistons! (Engine was still smooth to turn over and work colleague could not afford bottom end rebuild so we informed of possible bottom end failure and repaired/cleaned up to the point where it would run. Sad fact is a lot of younger people these days are buying vans for recreational use in the second hand market with around 100,000 miles on them - just around the mileage when these belts fail....... They have already spent most of their money on the vehicle and cannot afford garage prices on a complete rebuild = Screwed. As this Great Video suggests, AVOID!
I have a 2016 K9K engined Dacia Logan MCV car, fantastic on fuel and it is indeed a dry belt 👌 I work in agriculture and the wet belt scam mystifies all of me and my colleagues. A tractor manufacturer trying this blindingly obvious planned obsolescency would lose generations of customers overnight - by trying to fleece them this hard! So, so, so very dumb!
Ironically the only real solution to combat planned obsolescence is consumer awareness, this video being a prime example. Now it's up to us viewers to do our job and tell all of our friends and family to boycott wet timing belts.
Hahaha. Bro every car is fcked. Cars have thousands of parts. If they don't get you in one area they will just get you in another. We as consumers have very little power. Auto manufacturers have the USA by the balls. If we don't have cars our society crumbles because we don't have good public transportation. We are completely and utterly dependent on them, so they can do whatever they want and get away with it. We have no bargaining power.
@@faustinpippin9208But then the manufacturers think of terms and conditions like the car has to be serviced by their own dealerships or refuse people who went over their service interval distance by a small bit. It's better not to buy any of the cars that have one.

You can blame the company(s), but ultimately this goes back to regulations from the governments, full of people who don't understand ANY of these engineering problems, demanding better and better emissions. 😒
They should have stopped pushing a long time ago, and just accepted the significant gains already achieved.

Instead of a Product that you buy once every 25-50 years, you buy a product that you have to replace every few years. Even Lightbulb manufacturing has a Limit to the number of hours the Bulbs are allowed to last for the reason that they can keep making and selling them continuously. Yep, Evil, Dastardly Consumerism. And it has gotten worse and worse over the last 75 years. They don't even try to hide it it seems. I Love your Cannel Man! Awesome, Educational, and Informative!
BMW also earns extra points for making timing chains that fail before timing belts.
Blown Motor Werke
The timing chain can't fail if the shitty plastic chain guide fails before ! ... Bmw logic
and also .....but not only bmw , others do too ....BMW spared ONE ( 1 ) lid and gasket and moved to timing stuff to....the worst place to be for a timing chain , at the point where the most vibrations and inkonsistency occurs , at the clutch .
and it makes it more expensive to maintain or change .
sometimes engineers need a slap to the back of their heads .
BMW's are not know for failing timing chains. Failing VANOS, connecting rod bearings, HP fuel pumps, plastic connectors, etc. but not timing chains.
BMW claims to be the "Driver's car". They never claimed to be the " Owner's car" :^)
But, a snapped belt means 100% fuel savings and a 100% silent engine.

@@MrKalashnikov47 How do you hold the Kevlar fibers together?😉

Ford should take notes from Honda lawnmower engines. Honda mower engine have had wet timing belts for years and I haven’t heard about any breaking. I’m sure a couple probably have broken but not nearly as much as ford
It is hilarious how Ford now makes 1.0L Ecoboost with a timing chain but it still has a wet rubber belt for the oil pump.
"Ford now makes" - you meant to say "Ford is required under threat of law." Ford would rather not make a 1.0L ecoboost. They have to because of draconian unrealistic governmental regulations and laws which require automakers to squeeze 1000mpg out of their engines on average because "saving the earth" or something while their campaigns are funded by green corporations and they personally have investments in electric car companies.
@@RandomAccessMemoryloss its almost like they want to sell more of these replacement belts
The Ford "Fox" 1.0 3 cylinder engine was introduced with a wet belt which worked without problems for many years. However, Ford wanted to introduce a new version of the engine, I think with cylinder deactivation. This put more load on the cam drive. The belt supplier was unable to develop an uprated belt within Ford's timetable so chain was used on the new version. Wet belt oil pump drives are more common than wet belt cam drives.
@@RandomAccessMemoryloss Gears are expensive. I'm not sure if they are used outside of pure race engines.
@@RandomAccessMemoryloss I dispute the information presented in this video. If I see some data proving that wet belts are prone to failure I'll change my view. Tons of blown engines are a myth. Many people are biased against belt drives - particularly in North America - a place where many car owners still think a pushrod engine is a good idea.
The continued use of wet belts despite the known drawbacks only reinforces the
belief that modern cars are not being built for long-term reliability.
Awesome job on this video. 👏👏👏
Cars are being built by the government.
The manufacturers don’t care as the belts fail after the warranty is up. Then they can sell parts or entire engines and add to the bottom line. They figure (rightfully so) that buyers mostly buy another brand of vehicle whether they have had trouble or not, so why should they spend pennies to try to keep them as customers? It’s all in the actuary charts for them. Also, decent cars now last 10 years or more, so a frugal person will own, what, 5 new cars in a lifetime? Even less incentive to do the right thing for them.
Wouldn’t expect anything less from Ford, same company that brought you the Pinto
@@blauer2551I had Two Pinto's and both were really reliable and easy to work on. The best one was the 2000cc engine in the '73 it actually had 5 main bearings in the block. Thats the same as most V-8 engines.

We had a Ford Ecosport fail the wet belt at 19,000 miles. Fully Dealer serviced and under warranty. Service manager accidently slipped and said, "Oh, we have had a few of these this year"! We shopped for another vehicle without a wet belt!
We don't see many on the roads much now
... and it was only January 1st 😉
I watched a teardown of the Eco boost engine with the rubber timing belt it was prematurely cracked with rubber particles in the pick up tube which caused the engine to fail the belt looked like an old timing belt you would find in a 06 Honda Accord that hasn’t been changed since new
I have a Ford custom 185 pk now 250.000 km Replaced the first belt at 180.000 km oil change every 15 max 20.000 km

I work in an automotive component supply company, the illusion that parts are tested prior to launch is a hark back to olden times. There’s a computer based modelling of lifetime stresses and then the bean counters force a launch and everybody crosses their fingers for the best. I’ve even seen defective product shipped before a solution was found to avoid late delivery penalties. The Japanese are the only ones with tight standards hence why I only drive Japanese cars.
I've worked in the automotive industry and you're correct, everything and that IS everything is driven by profit! I've been in meetings where a known problem is being discussed and the conclusion has been to leave it alone, fight any warranty claims and, if compensation is paid out it's still cheaper than a production line change.
WOW Im somehow not that suprised, but still WOW
@@mr.g167 Ford decided that it's cheaper to pay potenantial insurance compensation for people's deaths in car accidents than reshape their fuel tank so that there was no risk of explosion after being hit. Just google Ford Pinto & "enjoy".

Not everything is driven by profit... some of it is driven by pure stupidity, and most of it by politics wrapped in so called regulation and green initiative that is all but not green
@@markrowland1366 Yeah! Then the batteries bump a rock and you have to scrap them because the warning button popped off (warning that the battery might have swelled).

I'm from Brazil, Yes we have middle age problems AND wet belts. I always recommend people to ask before purchasing a new car, if it has wet belt don't go any further. But most of people just choose cars by their design and comfort items
You hit the nail on the head, if potential car buyers did any research at all everyone would be driving around in 20 year old Toyota Corollas.
I am guilty myself. I was happy to buy a newly designed engine w the last car, i was proud to have checked. But besides that i did not dig any deeper. One would think people could compare more easily these days, but where can i find all that detailed info in 1 spot. Or is the answer to everything Honda or Toyota. ?

Add in poorly made electronics and buggy software, and you have it all!
I bought a diesel with a timing belt because it was easier to maintain than a v6 with chains that would be an engine out repair.
Better fuel mileage is nice but goes to higher maintenance cost.
Love the exhaust brake though.

You're a teacher and you spell "you're great video's" like that? OMG!
I owned an engine machine shop in California - lots of BMWs. I love them! Made a TON of money on BMW. When the belt or chain fails on a normal engine, the valves hit the piston (some "non-interference" engines don't, but most do), the valve is bent and the valve guides are ruined. So you cut out the valves , remove and replace the guides, hone them to fit do the other normal machine work ( machine the valve seats that are serviceable, replace seats that were damaged, deck the head, etc) and then it's good as new. With a BMW, the piston hits the valve and it breaks the overhead cam saddles right out of the head castings! We had tooling (custom designed and made) that allowed us to weld up the heads to form new saddles, which we would then re-machine. It was still cheaper for the Customer than buying a new head from BMW, and our head was stronger. The Customer gets back on the road with a lower cost, and I make money. It was so lucrative that I kept various BMW heads rebuilt and ready to go on the shelf. There was always demand! The workmanship from BMW was beautiful... but the engineering wasn't.
Just the same with BMW and VW turbos where if the wastegate fails, the whole turbo has to be replaced. German overengineered junk at its finest!
@@supergeekjay That is not true at all clown. The Wastegate is removable with 2 bolts. You can replace the actuator alone without replacing the entire turbocharger on any turbo made from BMW or VW. The only person who would tell you otherwise is a shop attempting to scam you. The wastegate/actuator is only $200. People like you need to never touch a wrench again.
Lexus also have interference engines. If the belt/chain snaps, the valves hit the pistons and destroy the entire engine. 80% of engines made by ALL manufacturers will do this and are interference. Where the hell is your shop? Facebook Marketplace? Jesus Christ. This is not a BMW only issue. It is called Interference vs. Non-Interference.
BMW means "Bring More Wallets"-- for repairs Or--"Break My Wallet"
Gone are the days where BMW are brick solid and can cover a million Mile without much fuss..nowadays it is all just that :$how off $how off and more of it
I'm am an automotive metallurgical engineer and a lot of my work engine R&D including both the specification side and the wear and failure analysis side. I have never witnessed a conversation that involved intentionally reducing the service life or reliability of any engine component, but I have been part of many conversations where my push (or the powertrain engineers' push) for more durable or reliable components got shot down on cost limitations. Management ALWAYS asks for more reliable engines, but they often set cost as a higher priority, and they almost always set fuel efficiency and emissions as the top priorities. Yes, the customer wants to pay for a reliable engine, but governments are forcing us to shave every tenth of a percent on both fuel efficiency and emissions. Automakers get fined hundreds of millions of dollars for selling customers the powerful, reliable engines they want instead of the 1% cleaner, 1% more efficient engines that sacrifice everything the customers want.
I don't believe higher management would ever disseminate or leave any proof that they would request engineers build less reliable engines. So of course they would use other tactics to reach the same result, such as reducing costs. So it makes sense you wouldn't hear about it
@@durragas4671 I've been involved in conversations that started with "what is the cheapest plastic we can make this part of" when nobody at that point in the design process knew what were the requirements for that part or if indeed plastic was suitable at all for that specific application.
governments are evil now days
I agree that the government is more responsible (rules, regulation and fines) for this than the automakers. Still the companies bean counters are to blame also.
That's because governments wanted the internal combustion engine gone, or severely limited decades ago. It all began with (over here) ridiculously high taxes on fuels. And the car manufacturers did not want to comply and kept on going with old tech (combustion engines). That had to clash at some point, and the consumer is the one paying the bill.
As an ex-ford tech, we replaced quite a few transit custom engines due to wet belt failure at around 180k kms, pretty consistently. They would just rip teeth off the belt.
Lasted longer than dry belts..
Ford: Built Tough 😤🥴
@neilasd3043 Did it really? The last car we had with a dry belt had it replaced at 160KKM as preventive maintenance. It was still in good condition. Not to mention that the job is a lot less labour intensive and therefore cheaper.
Well as long as it’s out of warranty then ford is OK with that. They get to sell a van and a spare engine!
Maybe that's why the owner should have replaced it at 120k kilometers
I am a mechanic. I WILL NOT OWN A BELT driven This video is extremely informative. Thank you sir. Everyone needs to see this.
Meanwhile, failing chain tensioners: ☠️
@@mipmipmipmipmip-v5x The belts need a tensioner too, they just don't give (as much) auditory warning on their way out.
@@mipmipmipmipmip-v5x Failing belt tensioners aren't any better. We had to replace like 3 alternators and the batteries (and the tensioner) a while back in our garage after one of the auxiliary belt tensioners locked up on a bus.
But hey, at least they fail quietly :^)
@@Daschickenifythey do, they rattle like fuck because the tensioner has gone slack and failed. Talking from experience
@@tommcmahon14 You're right, I misremembered. I've seen videos of failing timing belt tensioners and they do make noise.
Even with all the data proving that wet belts are a bad idea, yet car manufacturers continued to use it, in my mind is further proof that most cars nowadays are only being built to outlast the warranty period. The warranty period might as well be the guaranteed 'lifetime of the engine/car' at this point.
Capitalism goes brrr
GM could learn from this video evidence; guess their main goal is profit when their 1.3 liter 3 cylinder fail @ end of warranty, crush car & replace.
That's how warranties work in every industry. Any failure during the warranty period is considered _premature failure,_ but if it dies one day after the warranty period it is _past its expected lifespan._ The manufacturer doesn't want the product to fail under warranty because then they pay for it out of pocket, but they don't want it to last much longer than the warranty either because well... Any failure after the warranty period is _past its expected lifespan_ so why make something that works _too well_
@@Creepus_Explodus This is actually wrong. Many cars are leased out to corporations and the leasing company wants good residuals, which means that they must not be perceived as being unreliable when sold second hand.
Modern cars are expected to be reliable for 6 years, i.e. twice the typical lease. Over here Mercedes dealers will buy cars under 6 years old. Go over...well, I know someone who foolishly bought an Audi TT when she retired intending to keep it. After 6 years it started to get expensive and she then found out what the value was. No more Audis, the trade in didn't cover a used Polo.
@@kristoffer3000Yeah, the cars made in socialistic systems were so much better, right?
That one percent fuel saving would go straight out the window as soon as the engine goes into rich mode because of engine knock.
So Infact there is no saving at all, just more expense.
I must say this channel is one of the best, if not the best automotive channel on RUclips. Great work.
Same with the EGR lie! Reducing NOX with feeding the engine junk meant less of a percentage of nox at a higher fuel consumption. Burn more fuel = more profit for the industry with total nox actually gone up!
But the knock is not actually caused by the wet belt, is it? Not seeing the logic here.
It's probably BS too, there's NO chance those engines save a whole %1. There's barely any friction between the belt and gears to begin with...
Certainly the Ford 1l ecoboosts have long been known to get nowhere near their cited fuel economy figures and I would not be remotely surprised if that's because they end up running rich because of the normal driving conditions they find themselves in
Your mistake is thinking that 1% savings is to help the consumer. It's for regulations like CAFE
"I'm a fan of objectivity and rationality." A-effing-men, brother, speak it! This is the best-explained, best-reasoned takedown of the industry's painfully obvious wet belt scam. Absolutely beautiful.
They did it to flamboozle regulators: the 1% savings was all about milage gains [real or imagined]. The fact it costs consumers 1000x to maintain vs what gets saved at the pump? Not a concern of CAFE standards, or the politicians pretending they know anything about engineering or economics.
The lawsuits say it all... Sealants is losing their $#!^.... and that means money in the long run...
It's not a scam for profit. It's to satisfy the insane CAFE regs that are pushed by idiots that think a good EPA rating is all that matters. Look at what they've done to diesels. Pre EGR and DEF diesels were known for going a million miles. Now that's a pipe dream. They've been made so "clean" that you have to replace them or a number of components in less than a quarter of that service life, and producing a new vehicle is a way bigger generator of pollution than running the vehicle. It's a scam alright, but the green in it isn't about money it's about the morons thinking that EVs, solar, and wind are going to save us. It's all shortsighted stupidity.
I HATE rubber timing belts
@@jugears1081 Frankly, I prefer (a) gear-driven cam(s) but that's a lot more easily done on one of my Harleys than on an auto engine. 😀
I have a 1.0 civic turbo from 2020 that has an oil wet belt and it changes the oil every 9000km and the belt every 120000km. I am at 80000km and no problems yet related to that but your video is very cool and informative I am never buying a car again without carefully investigating more on its engine. Thanks!
I'm an automotive technician and I was working on a 2019 Ford ecotec it came in with low oil pressure. I found that belt material from the belt driven oil pump Had plugged the oil pickup tube. The vehicle only had 60 thousand miles
I work in the auto industry and can 100% tell you, this sort of thing is absolutely intentional. If they could get away with it, they would make them even worse so they could make money. As long as it survives the warranty duration, that is all they care about. Anything after that is profit.
I worked in the engine rebuilding trade in the 70s. Many teardowns revealed engines in serviceable condition except for the failure of the iron camshaft timing gear with molded plastic / nylon teeth around the perimeter.. I guess the idea was to make engine quieter, and it was great until the teeth crumbled.
Having worked with engineers, this is most likely gross incompetence rather than malice. The engineers know it's a bad idea, but the higher ups think they know better than the engineers, and guess who signs the paychecks. It's not designed to force you to have to repair it, it's just stupidity running the engineering department rather than actual engineers.
@@Bitterrootbackroads That happened to my 1976 Ford Torino (351 Windsor). IIRC the camshaft timing gear was aluminum with the nylon teeth. Fortunately, it jumped timing in my driveway and fixing it involved merely replacing the timing set with all-metal gears, lining up the marks, and putting it back together. That engine ran for many more miles...
@@richardmillhousenixonand here is the explanation why Boeing is so bad at the moment. Yes you need to make sure you can make money. But you also need to make sure that the product you make is not a death trap.
Next stop... plastic timing chains, maybe from VW. Oh how they love plastic engine parts.
I never thought that engines with timing chains were noisy. Never.
I can't recall hearing the timing chain on any engine, ever. Even my dad's Cadillacs, which were overall very quiet, had enough other noises going on that you couldn't hear the timing chain.
usually the injectors are noiser than the engine itself.
Go buy a VW with a chain 😂😂
It's the lie the manufacturers tell you so you think it's a benefit.
they likely where in the 60s. now the chains are guided by plastic the whole way so no room left for clacking
Great video - absolutely loved your description of the problem and its likely driver. I am definitely taking your advice and avoiding wet belt engines. I currently drive a GM Mokka with the 1.4T Petrol engine, and I change the oil every six months or so (for me, that's about 5k miles). I shall be changing soon to something like a Nissan Qashqai.
This is amazing timing, a week ago I was showing my best friend a wet belt in a Ford EcoBoost. He thought it was insane as well. The thing is a timing chain in an engine with regular oil changes can often outlast the car. I have an GMC Atlas 4.2 and it has over 330,000km on the original timing chain and I'm still driving it, let's see your wet belt do that. 🙄
muricans using km. truly a nice surprise. god bless
A Ford dealer here in Germany quoted me 2850€ (roughly 3000 $) for a Timingbelt change on my 1.0 Ecoboost.
I have 10 years of fixing all sorts of vehicles under my belt,
but theres just no way i could do that job on the Parking lot of my appartment.
You need an entire Briefcase of special tools AND pull appart half of the Engine
(best would be to just rip the engine out at that point),
for a job the takes 1 1/2 hours on a old VW/ Opel/ French car. (2 hours if knock one back with the bois while i`m at it)
Not talking about the gigantic mess of oil or
the "shit, now i need this specific part from the dealer i forgot to buy/ broke"- moment.
Hell, doing a CLUTCH-job on most cars is easier and faster then this shit.
€3k to replace the belt? Scam.
That quote is ridiculous. Presumably that's an official Ford dealer? I drive Fords for a very good reason, and that's because they are good value for money, reliable, and cheap to service and fix. But your quote totally undermines that concept of value for money for the customer.
Surely, you could get a better quote than that if you go to a good franchise dealer, or even a specialist mechanic shop with a good reputation?
One could buy an entire second hand car with that kind of money.
@@richardconway6425 You must drive 40 year old fords or something, everything they've made since has been utter garbage.
I've seen a picture of a Ford engine that has the oil pump driven by a wet belt, that goes around the crank, so you'd need to remove the crank to replace the belt, a belt that is emersed in viscous oil, wedging itself between the pulley and belt. Mental.

You are absolutely right that too many times, people do not do the right thing. They do not do the human thing in the way they act towards others.

These kinds of things pop up from time to time and have done over the years.
What HAS changed, is that the manufacturers don't care like they used to.
They used to care that they had released an inferior product and would work hard to make the replacement better.
An example on a personal note, I owned a Spanish built D40 Nissan Navara 2.5 diesel. They became renowned for timing chain failures in the Renault engine after using fine pitch chains and plastic guides to reduce engine noise. (Mine was replaced by Nissan as a 'good will' warranty claim at 113,000km).
I now own a D23 Navara and it says in the owners handbook, timing chain replacement due at 300,000km. If that chain fails before then, Nissan will need to be very clear why it has, and why I should be responsible for replacing it.
I agree that the attitude of manufactures have gone downhill to our detriment. It appears their strategy has changed to accommodate this: they are selling on features more and more, capitalizing on the current popularity of high tec electronic gadgets. Their advertising pushes all the convenience features indoctrinating the younger generations that they deserve to be pampered by their vehicle. Does anyone repair their own vehicle anymore ???
The situation is made worse by the ridiculous extent fuel mileage regulatory requirements have pushed. Regulations are so far past the point of diminishing returns the life cycle cost of hardware is probably greater than the fuel cost improvement. The auto manufacturers actually like this, as it makes the service lifetime shorter for all manufactures !
The engine in my 1943 Farmall tractor has timing gears and has been running reliably for 81 years. Yeah, maybe could use a ring job, but still basically bulletproof.
Several Honda motorcycle models were having reliability issues in the late 70's / early 80's with cam chains (& tensioners/guides) so, probably in desperation as their
reputation was taking a hit, introduced gear driven cam shafts on their VFR400 & 750 V-fours & CBR 400 in-line 4 cyl's. Reliability & longevity issues were solved.

I agree but GM managed to mess up this with a 2.5 liter in 1980s with one of the gear made of plastic.

As someone who is working in the automotive industry, I can say with confidence that this is probably gross incompetence rather than malice.

They hear about a technology at a convention and force engineering to implement it against their will. Sometimes they sell it before we even heard about it. It was probably like that at Ford, it was certainly like that at VW, Opel.. after somone from sales heard the 1% fuel savings number.
Same in software engineering. Some idiot promises and sells high heaven with 'Tec X', then they come to the software architects/programmers "So you need to do this, because I sold it and that is our most profitable deal in years."

I’ve just had to take the front end off my Renault master , radiator out and remove starter motor to get at the hole to screw the timing pin in to lock the crankshaft to change the timing chain, and remove top engine mount 🤷 engineers now come on a dingy 😂
@@phoenixcustomrifles1430 I hold in high regard the academic achievement of any engineer . However , in my experience there are few these days who can see further than their computer models . It requires common sense , not just intelligence, to use such powerful tools correctly .
If you want to avoid these kinds of problems, check out the front of the car. If there is a circle on it that contains four pie parts alternating between white and blue, slowly back away and run as fast as possible when you are out of sight.
How about if there are four rings overlapping each other? 😃

Thanks for sharing this. I only found out that wet belts were a thing about a year ago, couldn't believe that anyone could think that this was a good idea. Personally I think that OEM's should be held accountable under consumer legislation and be required to offer a chain drive retrofit at cost and with free installation. To me the oil pump drives should always have the most durable and reliable drive technology of any drive within an engine, to choose a wet belt is guarantee of catastrophic engine failure at some point in the life of that engine, unless you do oil changes at 5000 km AND you are very lucky. MADNESS!
Honda also decided to use wet timing belt in Honda City 1.0 turbo which is one of the best selling here in Thailand. Timing belt de-lamination has becoming commonly found problem in this model as it older.
This problem costs a lots money from the users since the pieces of de-laminated belt usually clogged VTEC solenoid strainer or engine oil pump strainer which caused oil starvation problem and broke the engine.
BTW, Thank you for good video!
I think they also used this "technology" on the Honda Civic 1.0 Turbo sold in Europe
But i would expect Honda should react better and repair all of them at no cost.
was going to say this, it's also sold in EU and ofc with the sames issues. Engine code P10A2 for thoses interested.
@@stefanmargraf7878 Yes if you pay for their expensive extended warranty. No otherwise. I had a month to go on my extended on a civic when mine destroyed itself for a 2nd time.
I think they only used that belt in the 1.0T not in the diesel engine. The diesel had a chain.
Man, I watch a lot of your videos (M.E. here) and I just want to let you know, I appreciate your passion and bluntness immensely. You don’t try to fake reality in any way, I don’t know a better way to put it. Love from California.
Great video. Brilliant explanation, easily understood and I'm completely amazed these manufactures are still producing these and not recalling all their engines to refit a decent timng system.
Thanks for the video. Many people owning these cars aren't aware of the wet belt peculiarities. PSA reverted to timing chains but kept the wet belt in the oil pump.
Yeah, makes sense for non-critical and easily replaced items like oil pumps to save a few bucks
WHAT !?
Just looked it up, i cannot find any pictures of the gen3 engine with wet belts, only chains on the valve train and the oil pump.

Regulatory Powers sadly can't keep up with changes or updates in the industry, so sometimes it's the customer who need to force changes for the better, by voting with its wallet. But the regular consumer isn't qualified enough to overview things like this. That's the reason why unbiased reviewers and journalists like here on youtube are so important.
In most cases consumers are just to damn lazy to get an overview, they will just buy any ugly crossover with ridiculously large wheels. I'm still baffled how people will buy a >30k€ car without searching google for 5 minutes, take the Peugeot PureTech engine for instance, they have been notorious for belt failure for the last 12 years yet people will buy it without any hesitation or personal research.
My relatives had a Fiesta where the timing belt broke at 48,000km. Vehicle was 4 years old, maintenance only at the dealer.
After a bit of back and forth it went under warranty, but they then sold the car and bought an older Toyota Yaris.
I have a 2002 toyota yaris. The engine runs fine.
I have a 2004 Toyota Echo. 380,000km. Still running good. No timing chain noise.

What's your point?
@@ickebins6948Your 2004 model is a pre wet-belt engine so you won't have the issues discussed in this video or comment.
This is simply the best RUclips post I have seen. Every point you make is spot on and makes complete sense. Thank you for this although it was too late for my son's 2017 Fiesta Ecoboost which died due to oil starvation because of this "feature" in 2023. The only saving grace from this was that he got a good scrap valuation due to the demand for second hand prices for ECUs.
Our company had a fleet of vehicles from a rental company who managed the fleet, and most cars had engines with wet belts. There were numerous cases of engine failure with 60K km because of debris from the wear of the belt clogging the oil ducts, pumps and so on. To make it worse, the maintenance was performed by third party workshops (not the car brand workshops) selected by the rental company, and the oil approved by the rental company was not the correct specification as the car's manual...
You left us on clifhanger, whats happened next?
This sounds like 1.0 Ecoboost or PSA Puretech
Oil type doesn't matter. That's just a Ford lie to attempt escaping fault.
@@MiGujack3 It was a 1.5 3-cylinder from Ford. Overall a good engine, with good power and fuel economy, but with this terrible maintenance issue
@@AndriusKamarauskas The rental company had to replace engines on some cars, but eventually due to several other problems with maintenance of that car model, the management at my company demanded an action to avoid lost time and ensure safety for the employees, then they anticipated the renewal of the contract to replace the fleet with another model (fortunately, the new car uses timing chain instead)
12:50 Our Insignia gave us the "Stop Engine Immediately" message on a freezing cold morning start. It was the pump 'O' ring. We got it replaced straight away before damage could be done.
thank god i did not buy an opel, i dont get how they could screw up an o-ring after this many years of knowledge
You know; that is actually a Fiat engine, which they used on their (GM) cars!
You're one of the very few owners to recognize the emergency convaid by that simple warning light. Most people would put time considerations ahead of the state of their vehicle...
@@jayasankabandara4792doesn't matter who design or built the engine. It was flawed from the start.
Sell it,, don't waste time with that car. Not only the O-ring will fail, but also the oil pump and many more. Remove it till it still works, those are nightmare engine to rebuild after that and with big chance of failing again.
Please remember that most of those engines were mostly developed before the diesel gate. At this time, European emissions standards were hitting hard, with regular and stringent updates, even if some cheated or interpreted it in some edgy ways. Bean counting design has been applied to so many engines back then, especially on the emission side of the spectrum.
Also, the market was more lively than it is today, and all manufacturers were trying to avoid echoing those development costs to the customer.
I worked as a machining engineer in camshaft/crankshaft manufacturing in the late 2010s. We had to cope with some design updates for like, -0,2 grams of CO2 per km.
Now, imagine if you follow the same search for minimal gains for a totally new design. If a design project leader was able to demonstrate he could maintain the same engine on the market for the next 2 or 3 euro emission updates, he would most certainly take the cake. So they generally stacked cheap, unproven, quick to develop solutions to obtain their results, without thinking of the aftermath.
Those consumption reductions were never meant to be perceived by the consumer, their intent was to develop a new euro compliant engine as cheaply as possible, that could be sold for many years without much updates, no matter the long term reliability. Small downsized 3 cylinders are just a plain example of their own.
What worries me the most is that they somehow have to compensate back the emission gains another way around if they bring back more reliable solutions.
Any ICE update or ground-up design is incredibly expensive for a manufacturer, and nowadays this will most definitely impact the selling cost.
in norway we have cold winter's. and a lot of ppl by these small cars to do short trips. the engines never get hot and the fuel dilution gets to be high. i have NOT seen a 1.2 PSA engine make it to 60k km without failure in those conditions. The belt start to fall apart and then clog the oil pickup and the engine is run 10-15k km on low oil pressure before the lamp comes and and ask you to stop. by then the damage is done.
I think there is a significant chance that these manufacturers promoted their accountants and gave them the title of "engineer" instead.
Financial engineer??
Ford's engineers come from the accounting department. Italian and French engineers are just stupid.
Ferrari's engines for example were designed by idiots. Every single part is terribly designed and put in awful places. You can't even access the crankshaft without taking the entire engine apart. I'd be ashamed to to sign my name on those projects if I was them.

@fladave99 "This growth can be attributed to sales of full and mild hybrids, which grew by 21% in Q2 2024 vs. Q2 2023. Hybrid sales growth was particularly apparent in France (40%) and Spain (27%). The hybrid market share in the EU top 5 now stands at 32%, meaning that almost one in three vehicles now sold in the region are hybrids."
They just want to sell more cars and they are incentivised to do it because idiots keep buying these cars after companies crap on them.
The process you describe at 10:40 is exactly what happened to a friend of mine who had purchased a very young Ford Focus estate 1 litre. It had less than 60.000 km on the clock when a blocked oil strainer left them stranded.
The engine survived but the cost of cleaning up, replacing the belt was close to 2k, on a car they had paid close to 30k for a little over a year earlier….
I heard in the medias that those engines were having issues, and thought that it was probably badly maintained vehicules, or just a bunch of people with bad luck.
It was very interesting to hear the actual technical explanation behind that.
When I first heard about a wet belt in an engine my immediate reaction was - what a stupid idea. Thanks for validating my reaction. Excellent analysis.
Toyota used dry belts on non-interference engines such as the Camry. Belt breakage caused no engine damage.
We can conclude that engineering exists to make an engine last 500k miles. Engineers now focus solely on timing big failures just outside the warranty expiration. The closer they get to the expiration date, the better the engineering job. Kudos to the folks at BMW - you are at the head of the class!! 👊
A Yamaha XJR1300 Timing Chain only lasts up to 498kkm. Must be a weak design............ for a Motorbike.
...engineering USED TO exist to make an engine last 500k... Yep, now they want things just barely good enough to outlast warranty, aka planned obsolescence.
Don’t assume malice when incompetence is a good explanation. A lot of the oldtime grease-under-the-fingernails engineers are gone and companies are stuck with CAD monkeys that couldn’t even change the oil in their lawnmowers.
😂yes....Original Lexus LS400 engine. Pure silk designed to basically run forever, for instance. Or the original red block Volvo with a timing gear/sprocket....
Been like that since the 90s if not mid 80s.
I am working daily on the 1.2T Pure Tech from Peugeot. It is absolute shit. We had more than 100 instances of premature belt replacement in 2023. And by premature I dont mean like you said around 100k km, I mean 35-50k km. The earliest was around 20k if I remember correctly. Peugot has in time done four things to combat this:
The service interval was reduced from 30.000km to 20.000km, the belt interval was reduced to 60.000km, checking the belt is now a point on the yearly insepaction, with the tool you showed, the wet belt design was replaced by a chain in late '23.
And you must use a special Oil for (in Germany) 30€ per litre. Every service.
😂, enjoying the diagnostic? Thoes engine came new 2017 ish, engine problem starts not even reach 10000km.
Had this engine, serviced by book at the dealership. Even had the belt replaced prematurely due to cracking. Still, at 110k km the engine was done due to running dry (pieces of rubber blocked the oil pathways). THe dealer was quite frank by telling me they could in theory get me a new short block and fix it but in practice I should get rid of the car and get something else because the engine is total crap made for 100-150kkm. It was at time when they stopped selling diesels in EU and only had this engine in their lineup so they basically told me to buy car from someone else.
Have the car with that engine. The belt failed around 60kkm and engine was repaired under warranty.
5:27 Renault 1,2 and 0,9 tce engines have timing chains.
1,5dci has dry timing belt, i have 2 from different ages and power. Dry belt.
Indeed, Renault has only dry belts and chain engines to my knowledge. Great video though!
Yes, the engine in my Dacia Logan MCV 0,9tce has a timing chain.
That's correct, but the 1.2 TCe is also known for segmentation issues, which also catastrophically broke the engine early. At least they fairly quickly fixed it around the end of 2016 and moved on to the pretty good 1.3 TCe after 2017.

With good maintenance they serve us quite well. Only 1.5dci, 2.5dci and old D7F have dry timing belts but that is not a problem, they are not sensitive.

My ford Ranger 2.0 Bi-turbo use this timing belt belt dip in oil engine. The manual said to replace it at 240,000Km but I heard that a large number truck of the same model have issue of timing belt break before reaching 200,000Km. So, on my 165,000Km oil change, I decided to have the timing belt change as well. And sure enough, the old timing belt the coms out of my truck had a lot of crack on its rubber. My mechanic told me I made the right called, the original timing belt wouldn't last another 1000Km.
My neighbour just bought a new Citroen C4 with a 3-cylinder wet-belt engine and it runs so hot that the tops of the front wings become almost too hot to touch. His new car replaces another wet-belt C4 for which he was quoted £1200 to replace the belt, and yet he bought another. He's a Citroen devotee since the days when the Peugeot Citreon made pretty good diesels.
Ah yes. 2.0 HDi. 136kms (or 110 in 8v head). 5L/100Km and it does over 500k kms without much problems. And they can be easly remapped (136km -> 170km) with even more fuel saving. I was able to get... 4.3L/100kms doing constant 90km/h.
The Xantia was the last car Citroen made that deserved the Citroen name 😞.
He will get the Puretech curse sooner or later.
I've reached this video after I did a relatively random timing belt check on my 1.2 Puretech equipped Citroen C3 Aircross before a 200km trip and found that it had formed cracks. That belt is no older than about 50-60.000km in an engine that receives full synthetic oil on a relatively regular basis but that does see a lot of stop and go traffic. An absolutely terrible idea for any engine but especially for a city car. Thank you for making this video.
One of the worst things with the wet belt on the Transit van is it sheds particles which block the oil feed to the vacuum pump - the result of this is the vehicle brakes fail when you don't expect it. One of my neighbours nearly had a very bad accident when trying to stop.
That doesn't make any sense. Vacuum is created by the intake.
@@JHe-f9t The vacuum pump on the transit has a oil inlet with a hole about 1mm in diameter. Doesn't take much to clog it - then the pump stops working and has to be replaced.
@@JHe-f9t Diesel engines use vacuum pumps.
@@AndyFletcherX31So ford in their infinite wisdom took an existing vacuum system that has worked for forever that has no moving parts and is free and put in a vacuum pump?! And it's $500 to replace?!
And I thought ford from the early 2000s were bad...
@user-yu8ur9yi9e turbo engines don't make consistent vacuum, the intake is pressurized and the vaccum infront of the turbo isnt enough on even gas engines now. So they fit mechanical vacuum pumps to run the power brake booster no matter the engine boost level, this isn't a ford thing it's a all turbo engine thing. Diesels have had them forever and now gas engines have them.
I have owned two Ford products, a Lincoln Continental and an E-150 van. While both had steel oil pans, they apparently were painted with a coating which allowed road salt and moisture to work it's way under and eat through the pan, causing the oil to leak out. I repaired each in turn with a material from an auto parts store which reduced the leaks to an occasional drip and got rid of the vehicles. Part of the price we pay to live in the rust belt Thanks, Ford
I used to work for a major European car manufacturer. They released a new engine in the early 2000's, which had a timing chain that wasn't designed to be replaced. Instead, I was told the engine was designed for 100,000 miles (with regular scheduled servicing) and anything after that was a bonus. The point is, for any manufacturer to keep selling cars, they don't want long lasting cars that keep on going.
TBF, 100k miles on a car back then in Europe was a lot.
@@Okurka. And ironically it also is now.
@@Okurka. It really wasn't. Basically every EA827 VW motor except for the G40/G60 would do 150k+ miles no problem. Which is also why they were available dirt cheap on junk yards for ages - VWs were scrapped because they rusted out, not due to engine wear.

8:08 DING DING DING DINGGGGG. This is why car manufacturers consider wet belt a success.
Exactly, they want people to buy new engines
Planned obsolescence.
Ford products are garbage this is one more reason why. Even if you wanted to drop the oil pan and clean the pickup tube the Oil pan are "single use" . Ford robs people blind and they would be out of business if they didn't have fleet accounts.
IMO, any vehicle that has a rubber timing belt should be a non-interference engine.
traditional belts are very dependable, provided you change belt and tensioner regularly. Belt kits are inexpensive, and the job is no big deal.
@@jmbpinto73eh, accessing the belt to change it is a pain in the behind, especially in modern cramped engine compartments, and particularly in small cars with even less space. Of course there's experience involved, and I'm not a mechanic, but let's just say I do not look forward to when my car will soon need its belt changed - and I believe I've heard from plenty mechanics that they don't like the clearance around modern engines' belts, either.
@@mnxs That's not a problem with the belts though, that's a universal problem with engines becoming more complex and compact. If you think a timing belt with bad access is bad, try a timing chain.
Agreed. My Camry has a non-interference engine. The timing belt snapped at 180,000 back in 2015. Belt was replaced for $500 and the car is still driving at 250,000.
Interference engines are more and more the standard type as they squeeze out another 1% in fuel economy. As this is the case, the vast majority of engines would have chains of the manufacturers cared. Honda uses only interference engines these days and went to chains when the numbers showed that customers were replacing heads prematurely. They care and make the best performing and most reliable engines on the planet. That’s a tough combination, but they manage to pull it off.
Exactly what I have been thinking since I heard Fords Ecobust motors were running their belts in oil.
Just put in a much clearer and coherent manner than I ever could.
Great video.
Only the very small engines. The 2.0, 2.3, 2.7, and 3.5 liter engines have chains.

“Garbage technology“ - so true! This was the deciding factor I had when I selected Mazda CX-3 over the Peugeot 2008.
Hah I thought bout buying a Mazda Cx3 but it was too cramped for me.
Long story short I bought Ford Ecosport with 2.0 duratec(basically mazda engine xD) and 6f15 gearbox. Ohnestly the best combo for this small car and I would not touch ford 1.0 with 10m pole.

5:27 the Renault 1.5 dCi uses a dry timing belt, and the 1.2 TCe and 0.9 TCe use timing chains.
5:34 the VW 1.5 TSI uses a dry timing belt
5:40 the GM/Opel 1.5 turbo petrol engine has a timing chain.
16:42 the Honda 1.6 iDTEC uses a chain not a wet belt (you can even see the chain in the photo you used). It was the Honda 1.0L turbo 3 cylinder petrol engine (P10A2) which had the wet belt!
Was going to say this too, among the small displacement turbocharged engines, the 0.9tce from Renault must be one of the more reliable since it has a timing chain and multipoint injection, so less chance of admission carbon build up. Who knew old tech can still be good 😁
Correct, Renault didn't use wet belts on any engine afaik. @d4a maybe you should update the misleading info. Thanks for the video.

In this one here you raised a very important point. Thanks!
In 40 years driving front engined Porsches, I’ve changed dozens of belts, both cam and balance. A good belt was a dry belt - period. Those belts were a big deal to replace and tension properly and of course, interference engines. I got pretty damned good at it. If I could detect any sign of oil on those belts, I knew I had much bigger issues and that they were NOW issues.
If it's not leaking it's either a Porsche or it's not an old German car😂
@@finleymakee4850 Well, it took a second to parse your odd wording, but it looks like “only Porsches do not leak” which is close to true but old German cars all leak, which of course makes no sense.
@@artysanmobile If any old car doesn't leak at least a little that's how you know you gotta add some oil or you've got a bigger problem😅
You just did a great job of laying out the facts. As a retired mechanic it greatly disturbs me that the manufactures seem to not care once the garbage they produce is out of factory warranty (Ford Motor Company). Now also GM with their 3.0 liter Duramax Diesel that uses a wet belt to drive the engines oil pump. To replace this belt the transmission has to be removed! This is why we as consumers need to do a lot of research before buying. Your video is an important part of the information us consumers need to make an informed decision. Thank you.

honda came out with the GC160/GCV160 mower engines in the early 2000s, rubber timing belt that rode in the sump. I got out of the industry by 2012 but even to this day, I've never heard of one failing. Those were good little engines. After going through honda training school on them, they explained to us all these little things they had thought about. Like, for example, the choke lever had a nub made onto it so you could plug the fuel line with it. Everything was really designed as much as they could to make it easy to work on. I inquired about timing belt changes and while they did make the crankcase come apart in such a way you could change the belt, they said most would never need it, as it lasted the life of the engine. And, they were right, like I said, never saw one fail.
Of course, Honda was also making riding lawnmowers with timing belt driven engines back in 1985, which is just insane haha.
10 years on the wet belt in my gx25. Crazy how good these things are. Regularly see them with 25 years on them on fbm. But i bet it has something to do with the hp:belt ratio. Probably much better on these than cars.
It goes along with Ford's business model of "Fix Or Repair Daily", and "Found On Road Dead".

i work as a PSA mechanic and this problem with the 1.2 PureTech engines are a big problem at my workshop. alot of cars go under 100k km and still have cracking belts. also when the belt starts to crack the fibers in the belt starts getting loose and ends up in the oil pump and in turn the engine blows up because of no oil pressure. we have atleast 10-20 of these engines with broken belts/no compression sitting scrapped outside haha
6:23 cue my dad getting a €4300 bill because the vacuum pump of our B-Max (with the 1.0 EcoBoost) locked up and jumped the timing (and that's with a 25% discount because the bill already exceeded the market value of the car!)
Likewise with non servicable parts used in domestic appliances, parts that are 100% sure to fail just outside the warranty period. It's all very carefully planned. It's all down to profit margin.
We need mandatory minimum reliability and repairability standards for cars and appliances. I have a whole list of proposals.
@@gregorymalchuk272Yes, very hard agree. If you're unfamiliar, check out the "right to repair" movement.

That said though, Bosch/Siemens is surprisingly willing to continue supporting even their ancient machines from the late 80s onwards. You can still buy parts directly from BSH. Take that, Miele.
Sadly it'll never happen. There's no money in it products that last. It makes me sad that there's so many greenwashed initiatives while at the same time, so many products are designed to be binned after 1-5 years.
When I ran a business selling kit we designed and manufactured, we prided ourselves on the longevity and on going support for our products and built a reputation on it. It wasn't cheap though! It was great to see version 1.0 kit coming back for refurb 10 years after selling it...
Yeah. Always bought Zanussi front-loaders. When the drum-bearings failed, you could dismantle the outer drum and replace the bearings. Other manufacturers used a plastic outer drum, welded together at the factory.Don't know about our current one.
one thing that I find amazing is that f1 (pinnacle of motorsports engineering) is using timing GEARS instead of belts and chains for the last 20 years and no one even mentions it as a possibility to solve this problem once and for all.
There are engines with shaft drive instead of geers and belts.
There were engines made with timing gears, like the 3.0 liters diesel from VW used in the first generation of Tuareg. It basically never has to be serviced.
Super noisy and ineficient. Race cars usually have timing gears to be robust, but chains/belts are way more reliable in the long run because they make up for small changes im clearences and wear.
Like the 2CV !
A lot of race car engineering is inappropriate for road car applications as the goals are so different. NVH, cost and long-term reliability being the obvious ones. As you can imagine it's a lot more difficult to tightly control the position and precision tooth form of a series of gears versus a few gears connected by a much more compliant chain/belt.
Yeah, I had a ford ranger pick up that had a rubber timing belt.
When it fails, it takes a few valves with it.
I agree the idea of wet timing belt is endlessly stupid. So many people told manufacturers it is a bad idea. Yet they still did it. Obviously for profit, but not only, because they were able to whitewash this stupid idea with ecology (while in fact it is not).
Nevertheless, the problem is that we do not have enough competition on the car market (with the exception of Tesla and some of the chineese manufacturers, which bring other problems to the table). This is due to the fact that manufacturing entry level is exceptionally high and industry is over regulated. The second thing is, I am glad that there is a class action lawsuit against Stellantis for 1.2 Pure Tech, but other manufacturers should be sued as well. We need to bring back the consumer market by increasing the competition and increasing the consumer awareness - and this is something this great video does. Thank you!
I’m a mechanic and am not surprised as humanity is greedy. Technology moves on but humans never change
F-150 2.7 ecoboost, oil pump is belt driven, belt is inside the engine oil lubricated.
Worse still, its at the back of the engine block, where the transmission must be removed to access the belt.
Probably the most reliable wet-belt engine on the Planet. That thing is an anomaly.
2.7/3.0 EcoBoost and the 1.5L 3cyl EcoBoost, as well as the 2018+ 1.0L EcoBoost all have wet oil pump belts and timing chains for the cams
@@YZJBi have a 20 focus with the 1.5 😬
And the 2.7 is somehow a very stout and reliable engine
Thanks for your honest and objective presentation. I've been a victim of failed timing belt in my old Honda Accord 1986 model several times then, I vowed never to buy any Car that uses belt anymore and I maintained my stance till date.
As a sixty-something ex-engineer i was dumbfounded that a welt belt was used in a colleagues engine (Ford 85K). Upon removing the head just about every valve was bent and an entire top end rebuild was necessary + some re-modelling of the top of the pistons! (Engine was still smooth to turn over and work colleague could not afford bottom end rebuild so we informed of possible bottom end failure and repaired/cleaned up to the point where it would run. Sad fact is a lot of younger people these days are buying vans for recreational use in the second hand market with around 100,000 miles on them - just around the mileage when these belts fail....... They have already spent most of their money on the vehicle and cannot afford garage prices on a complete rebuild = Screwed. As this Great Video suggests, AVOID!
As far as I know the k9k 1.5 dci Renault diesel engine has not wet polymer timing belt. In all its variants , is polymer but not wet.
I have a 2016 K9K engined Dacia Logan MCV car, fantastic on fuel and it is indeed a dry belt 👌 I work in agriculture and the wet belt scam mystifies all of me and my colleagues. A tractor manufacturer trying this blindingly obvious planned obsolescency would lose generations of customers overnight - by trying to fleece them this hard! So, so, so very dumb!
Ironically the only real solution to combat planned obsolescence is consumer awareness, this video being a prime example.
Now it's up to us viewers to do our job and tell all of our friends and family to boycott wet timing belts.
Hahaha. Bro every car is fcked. Cars have thousands of parts. If they don't get you in one area they will just get you in another.
We as consumers have very little power. Auto manufacturers have the USA by the balls.
If we don't have cars our society crumbles because we don't have good public transportation. We are completely and utterly dependent on them, so they can do whatever they want and get away with it. We have no bargaining power.
Or extend te min warranty for things like cars to 10 years. 2 years is a joke for something like a car....
@@faustinpippin9208But then the manufacturers think of terms and conditions like the car has to be serviced by their own dealerships or refuse people who went over their service interval distance by a small bit. It's better not to buy any of the cars that have one.
Isn't it fun chasing the tail of reactionary economic pressures with moronic manufacturers?
we could legislate quality standards you know
