Insane that engine was functioning totally normal with a chunk of piston ring and skirt missing. Would have expected the oil control ring to come out as well missing that much support.
It would have eventually blowed a hole in the side of the block
From my experience with LS engines, turbos, and powdered metal rods, the rod on your failed cylinder looks bent to me. Right down near the wrist pin.
I've seen that happen to LS engines. Rod bends, then the skirt breaks off and you get that noise.
Pull that rod/piston and have a look.
first yaman LS forever .....and 2 hyperutectic and détonation very hard on piston skirt
I think you're right. I bent a rod on a supercharged 4.6 2v (powdered rods too) and it made similar noise and still ran. I cant remember if the piston was damaged at all or not, it most likely was.
Yes sad to say…anything mechanical can break down even when you follow all the maintenance requirements
Great video
Might have just been a piston with an internal flaw and it eventually let loose.
Glad to see you getting that content back out! We know you're busy. Thanks for all you do! PS, I never would have guessed that the root cause was "piston skirt failure". GOD BLESS, BRIAN!!!
Another Great diagnosis & video !
Now almost a Million subscribers that you have entrusted to your personal integrity.
Brian : WELL DONE !
Bad luck to get the one engine with the defective piston, but with thousands produced not surprising to have one bad egg.
People complain about things like this, but if you lived in a world where everything was perfect and lasted forever no one would have a job.
I saw an F150 3.5L Ecoboost with a hole in the block at 130k miles. Service history on the truck was perfect. Customer declined the long block. I was so mad for that customer that he did everything right and his engine still blew up. Usually the 3.5L Ecoboost is a reliable engine.
Keyword is sometimes
Hmm so strange.
what year is his truck?
@@bjornegan6421 I can't remember. This was a few years ago.
What a shame when the owner did everything right!
Filthy engine internally and high heat.
@@Ranger-vv2jvit's clean...that's not dirty
@@Ranger-vv2jvlooks like he’s probably got an aftermarket tune with all the stuff he has added on

Friends don’t let friends buy fords
Have a 2012 3.5 that just rolled over 200,000 miles, no issues at all
I barely got 70000 on my 2012 before the timing chain stretch. I replaced it with new VVT's, water pump and thermostat. That's with 3000 mile oil changes.
I replaced a 17 Expedition 3.5 last month with 80k on it. Main timing chain snapped and crashed the valves.
I'm hoping to get 300,000 K
I have a 2011 3.5 with 181,000 miles. Never had an issue!!
2019 expedition cam phasers timing chain 50k . POS
Keep making 4 cyl and 6 cyl do the work intended for a V8 and this will keep on happening
Yeah, pretty amazing that back in the 30's Henry knew he needed a V8 and today's morons think they know better. There was NOTHING wrong with the 351W engine. Nor the 4.9 liter straight 6. I own the latter in my 1994 F150 2wd 5 speed manual transmission. That truck is BULLET PROOF.
I love my 2018 F 150 3.5 It's been good to me never did me wrong. 257,894 on it now still going strong 💪
any leaks and how many miles have you put on it
I have no issues whatsoever... I run amsoil in it.
@@AllenStuckbut have you owned it since new or you bought it used
I purchased the truck brand new in 2018.
I've got the 2016 3.5L in a edge, normally aspirated. She's been good to me. I use Penzoil platinum 5W30, I will not use 5W20, Ford can get bent. The engine only turns about 1400-1500 @ 55 MPH. So why would you put light oil in a engine that is lugging all the time? Ah to wear out your main, rod, bearings and piston skirts. hmm. This is my opinion, but diesel uses thicker oils because they are lugging engines. I also use Motorcraft oil Filters since I know they have the Anti-Drain back valve. Which is extremely important for most Ford engines due to the fact the filter is mounted sideways.
As far as engine failures go, this was a best case scenario. It clearly ran good enough to get him home and not leave him stranded on the side of the road, like a LS would.
I've been seeing a lot of piston failures on all different makes and models. I wonder how many of these failure has to do with one of the largest piston manufactures moving all of their production to Mexico.
Funny, no one mentioned that, till now.
I’m impressed that piston ran as well as it did with boost!
defective casting most likely and eventually the piston would have disintegrated completely.
My dad's 1.0 Ecoboost did something similar, but the piston didn't completely shatter. Just a chunk of the skirt came off (I think it was Cylinder #2).
Because the entire block is cast iron, the cylinder walls had no visible damage, and the piston was mostly intact, so the head didn't have any damage on it as well. He threw a new piston in, new oil pump and belts, and it's been running great ever since.
1.0L Ecoboost is an engine I would avoid at all costs. Belt driven oil pump. I saw a bunch of those fail when I worked in a Ford dealership.
In the area of mass production, there’s always a small percentage of failures based on a variety of factors. Quality control is vital to the manufacturing process in any industry. It would be interesting what Ford knows about this issue and if their suppliers knew about this piston head.
More specifically, there"s a statistical distribution for all processes. Call it the bell curve. You always end up with some really good parts (right side of the bell curve), some lemons (left side of bell curve), and most are in the middle. Six Sigma processes seek to control the width of the bell curve precisely, not necessarily make it narrow, through process design and random sampling of produced parts. When you buy OEM parts, they generally have bell curves centered further to the right and that are narrower than aftermarket parts. But because there's always parts on the right side of the bell curve, even aftermarket parts do well sometimes. It's just that they end up back in the shop more often because of the wider bell curve leaving a lot of parts on the left (bad) side.
The problem is it 8snt a small problem this has happened to thousands of the 1 Gen 3 5L ecoboost motor. I own one and it has been the worst truck I have ever owned. Honestly I will never own a newer the. 2010 ford truck again. I currently have a 95 with over 250k on the clock and it is still running strong. However my 2011 with only 103k and was babied it's entire life blew up. Yet my 95 has been abused and used and keeps coming back for more.
Plenty of high mileage ecoboost engines out there with no issues.
@@MendicantBias1 based on who’s information? Our shop talks to Ford techs in our city. Issues with timing chains, tensioners and failing oil pumps on a weekly basis. Our independent shop has done what FMC did to the 5.4 3 valve and replace all of the worn components in the timing chain assembly area but upgraded to the Melling HO oil pump. There’s engine are great for shops.
YEAH and that's why they are *F O R D S* (garbage in - garbage out)
Mexican qality. We have same problems with those engines in Europe. Ofc made in mexico only
My guess is a micro crack in the skirt from when it was cast and over time it fatigued and let go.
Typical of what happens to airplane parts such as jet engine fan blades.
Looks like a high rev burnout.. and then suddenly your tires catch traction.. That sudden deceleration pulse at the crank.
He would have DEFINITELY heard it when it happened. I don't think he's giving the whole story. Maybe he let someone else drive it. but oh well
As someone who drives the non eco 3.7 it is ridiculously difficult to resist tromping that pedal on these vehicles. I kinda tense up when mine hits 6900 on the tach, but merging into 70 mph traffic is more fun.
I tend to agree with that. I have a '19 with the 3.5 and find that it is ridiculously easy to break the tires loose especially with the 3.55 rear end gears
@@jeffisaliar I drive a '12 Mustang, 3.7, 115,000 miles. It's making a similar noise now. I changed to 20W50 oil, and it helped a lot, but still there. Should I drop the pan for a peek?
What is this, I Do Cars Midwest style? Hahaha 🤣Can we at least get a water pump toss?
How many miles were on this engine?
Probably just a tiny casting defect that eventually traveled far enough to cause failure. Stuff happens. Bad luck.
I have a second gen 3.5 and had the cam phasers replaced under warranty. I have to say that it is the smoothest and quietest engine I have ever owned. The 10 speed transmission on the other hand is not smooth and it is going in for work soon before my warranty is up.
I will just keep my old 2003 4.6 sohc with 450,000 miles(1 timing set at 212,000 miles as precautions), never an issue and still runs like new...Great video....
Have the 5.4 2 valve and it’s got 318,000 still running flawless. All original internal
I just replaced my 1997 4.6, it only had 500,000 miles on it. 😄
Thought for sure it was a valve spring…bad piston manufacturing?
Thanks Brian for the great videos !!!!!
Or this was at the edge of "net fit" manufacturing. If that's true, how many engines are shipped out that have this kind of net fit.
EcoBoost was EcoToast! Guess: Original tiny casting defect kept getting gradually worse. ..... It's 10 years old, and cracks can propagate s-l-o-w-l-y in those piston skirts over time. When a jet engine blade or disk crack is present, sometimes it will take years for the engine to actually fail in flight (took 18 years for the 1989 DC-10 Sioux City crash to happen, from an oriignal manufacturing defect). So my guess is an original factory casting defect, and a "Fatigue Crack" propagation, making it past the warranty period.
Another great video. I learn something every time.
Question: I have a 2016 Gen1 (I think) 3.5 ecoboost and am starting to see some things go wrong, i.e. intermittent antifreeze leaks, slow, and a cracked exh. manifold causing the chirping on acceleration. When I'm ready to overhaul the engine, should I do a stock 1 for 1 swap with a factory crate, or upgrade components that typically fail? Or other option? TIA.
That would really frost you as an owner who tries to take good care of his engine and still has an indeterminate piston failure! All metal parts have a fatigue life, I guess that piston reached it's, a shame.
Thanks for all your videos! Have helped more than you know with our fleet of Fords!
Bad piston manufacturing . A flaw for sure.
Good ole Motorcraft oil , nice varnish. Not saying oil caused it but that's a lot of varnish, neglected it would be sludge . But he was using a cheap oil .
In todays world of vehicle manufacturing and other things as well,its all about profits and quality and durability takes the back seat.They analize and scrutinize every last single solitary component & cut every corner possible.
While we see a piston,crankshaft, camshaft, timing chain or whatever they see steel that cost money to manufacture.And if they can reduce the cost of that metal by lessening the makeup of it they absolutely will.
What we get is low quality metal that the engineers say "SHOULD" be able to meet the required specifications.And when quality is reduced to this point,failures will be numerous,reliability and durability will suffer greatly.
Its the same way with all these oils leaks we now have from all vehicle manufacturers. They can save money by using O rings and silicone rather than gaskets.
Its all about that bottom line & customer satisfaction is secondary.
I also feel that this green agenda also may play a role in why we now have so many failures. If the govt subsidizes the auto manufacturers to make unreliable, trouble plagued vehicles people will eventually get sick of the internal combustion, fossil fuel vehicles and purchase an equally unreliable E.V.
Meanwhile we simply have to soldier on through and do the best we can with what we have.
Why is there so much varnish in this engine at the front and oil pan? Everything else seems clean. Sounds like the owner was on top of the oil changes. Cheap oil?
And for a 'recent' oil change, that oil sure was dark.
Why not stay with this bucket design? Seems more simple
Had a gen1 eb farm truck for 7 years had the heck worked out of it never had major failures, 135k still ran strong.
I'm a 70's car mechanic and still going but working on industrial stuff. Back then most engine issues were due to the not so great oils and some people in small towns not heating up the engines enough to not created sludge and failures. But today, even with the best oils ever, I see all brands having issues that are destructive long before their time, excellent maintenance or not. Poor engineering and materials seems to not be specific to any one brand although some have way more issues that others. Like all the 5.4 3V with phasers. Other MFG brands that have VVT and all the extra and critical parts to try to make the engine get more gas mileage but then sacrifice on durability. Can't we got back to basic engines and just use the multi speed overdrive transmissions to get that extra MPG, because all these vehicles don't really seem to get the extra MPG and stay together for long enough to make it all cost effective. As here, a person can watch engine failure issues all day long and never run out of one to watch.
People drive these teucks like they are hotrods. I agree they are fast and fun to drive but constantly abusing any engine somethings got to give.
My buddy bought a brand new 2014 3.5 Ecoboost and it now has 400k and his finally did cam phasers and a turbo (leaking oil) around 350k. First time anything had ever been done to the truck.
245k on mine. Timing chain is out of spec according to ford
Is this why they went from, " Built Ford tough ", to Built ford Proud " ?
Today, it's 'Built Ford Diversely and Inclusively.
It's good to hear 'good' tapping and 'bad' tapping and know the difference. Thanks again.👍
Lesson? Don't buy into the new technology until it's been out for a few years.
Thanks for posting. Question how many miles were on this engine? And is it a rebuild able core?
Is it worth me doing the phasers and timing chain on my 2014 Ecoboost? 245K miles? Or should I just swap engine!
Looks expensive. Glad its not my bill.
15 k or so for a new one.
The piston is also cracked up beyond the oil control ring
You can't say great fuel mileage and Ecoboost 🤣🤣
I WAS a huge GM fan, 16 different 300,000 mile GMs in my family in the past 30 years all had the factory original engine.. I currently have a 2022 Silverado and it's a POS!!!
And why did he install an oil catch can??
If Ford felt it needed an oil catch can it would of had one from the factory...
Yep, the new 4 cylinder Silverado's are an absolute shame. Ask me how I know.
@@santaclause2875 I know!!
Garbage!!
I bet the owner has over reved that engine to death. It's no wonder it hasn't blown up in his face. I wonder how many burn outs he's done with it ! Once a hot rodder, you never go back.
Looks like rod is bent. Which can cause this failure. Wondering if the owner hydralocked the engine.......maybe doing an intake valve/engine decarbon cleaning or possibly sucking up water?
Connecting rod is bent. He probably had too much boost running through. Could be lying.
What do you think of 3.3 Seem to be pretty reliable
The answer is in the title wording . Its a ford😅😅😅
I wonder with all the aftermarket stuff he’s got on he most likely has a tune and that could have killed it.
Oh and Brian, thanks taking time out to show us the carnage.
I had an 1970 F350 in the shop with a 351, the reason it was in the shop was the rear axle shaft slid out, and the clutch was slipping. The rear main soaked the clutch so I dropped the pan and 3 piston skirts were in the pan. As per the customer do the seal, fix the clutch and axle and slam it altogether!
Back in the 1980's FORD 302 had "piston slap" on start ups, FoMoCo's response? "That's normal"
In the 1990's when FoMoCo owned Jaguar 4.0L engines had "soft" pistons. FORD has a long history of piston problems from my POV!
Good job getting to the bottom of this one Brian! 😎👍
I have 211k on my gen 1 running fine. Interesting he had after market coil packs 🤔. Just did my valve covers thanks to you!
Love my 2020 expedition, Ecoboost 3.5 for me from now on in all vehicles!
Yes!
I hope and pray that FoMo. is watching and taking notes... great content Brian, be safe pardner... 👍😎
Not much they can do about this issue, it was probably a defective piston from whoever makes the piston for Ford. The design of this piston looked to be rock solid. However in turbo applications I would've preferred forged pistons and crank.
Ford could give a flying F.
I would say that someone that uses Duralast ignition coils isn’t someone that treats their engine as they should. Obviously this didn’t lead to the broken piston (most likely a manufacturing defect) but just an observation.
Yeah, and why replace all the OEM coils with cheap junk anyways. Just replace the bad coil.
Had a friend do that (replaced all the coils and tossed the OEM ones, and then every 6 months to a year one of the duralast coils would fail when the OEMcs lasted over 10y before one failed. And it was only a 4 cylinder..
Were those duralast coils? They looked a little funny. Yeah why would you do that!!
Maybe a shop put them in and used Duralast to save money and charge more? We don't know and obviously it's a moot point now.
Dirty Last huh? 😅😅
If they were to make a movie about Ford's genius automotive engineering, it would have to be called "Shitty-Shitty, Bang-Bang"!!
I've been a loyal F150 owner for 20 years but this channel and my own experience with my 2019 5.0 has me looking at Tundras. Anyone feel the same or is it just me?
I would wait a year or two on the Tundra. They have been having issues with the new engines locking up. Wait for them to work the bugs out. I have a 2014 with the 5.7 I force. The engine is pretty bulletproof but not easy on gas. Too bad they stopped making them for that reason.
It's just the Internet. The bad stuff catches our attention. Millions of Ecoboost out there with no issues, but that doesn't make for good entertainment. That's not to say nothing ever goes wrong, but the major Gen 1 and Gen 2 Ecoboost issues have been identified, so now you know how much cash to set aside.
New tundras with turbos are having just as many problems as ford.
@@kineticchiropractic8268 They haven't been around long enough to see what percentage wind up with issues. Give it a few more years.
Keep what you have. The 5.0 is a beast.
Naturally aspirated as long as I possibly can
Sweet duralast coil
With turbos, could it have been a under load detonation, if it was a high load lean out and that cylinder blew the ring out? 5:11
How much does a new engine cost? Would it be worth rebuilding this one?
Love your channel. Has helped me alot with my 2011 Ford F150 fx4.
Wondering if I could pick your brain with some issues I am having with mine.
Quick version:
losing power ( think it's timing chain )
Random shifting or staying in high gear ( lead frame )
Turn signal stays on or won't fully engage
Rearview mirror backup will stay on for some time after shifting back into drive.
Tried scanning with forscan and Vlinker FS USB but keep getting connection issues and warning about not being able to read PCM DTS.
Here's the kicker: put about a yard of soil and sand in the back, and the truck ran like a dream for 2 days before I got the majority of it out. It was not in Tow/haul as when it was the issue came back.❤
I had the same noise on my 2015 3.5L. It turned out to be a broken skirt on #4 piston. My tech replaced the piston, re-honed the cylinder, while he was at it he replaced the water pump and timing chain and guides. All is good now. I have just over 220,000 miles.
When I worked for Jeep the 4 liters had huge piston slap issues. We would tear them down and find skirts in the pan pretty regularly.
The thing is they would run forever like that.
It was a poor design. The castings broke just under the pin holes. But they would just keep putting along.
Always on the thrust side
Perhaps it was caused by over exuberant acceleration cycles before the engine was warmed up. The piston being aluminum has to adequately expand and fill the cylinder as it heats up. A cold engine coupled with high turbocharger boost could have caused more piston slap than the casting could absorb.
To all the F150 haters, the fact that this engine ran and performed with this issue and didn’t fully come apart, is why Ford trucks stand above the rest.
Exactly what I thought of. Lots of clearance when cold, causes higher forces on the skirts. People don't seem to get that an engine needs to be properly warmed up before romping on it! Over time these higher stresses will fracture and break skirts.
I have a theory, when Ford did away with the 5.4L V8 and went with the 3.5L Ecoboost V6. Ford claimed the 3.5L produces more power and torque than the V8 and they may be right, but the bottom line is that you have a smaller crankshaft and 6 connecting rods and 6 pistons that are taking the stress load that used to be handled by 8 rods and 8 pistons. Could this added stress on the 3.5L Rods and Pistons lead to premature failure of the engine??
Jesus... bring back the simple, reliable and easy to work on single cam, one timing chain, pushrod engine.
Fu*k this over engineered complicated problematic difficult to repair and EXPENSIVE to repair bullshit!
I had a 19 transit with Ecoboost 3.5 it ran perfect like you said no mechanical misfire or anything. Did the teardown of the motor to discover problem and when the pan came off it was 5 out of six with same broken skirts the 6th was cracked. Wow right still didn't misfire. But knocked like crazy. Replaced pistons in that motor ran absolutely perfect and no more ticky ticky. Or "knocky knocky" I should say. Live your videos. You helped me through many problems over the years so keep it up and thank you.
Great video. It's very kind of you to answer emails my friend sent you about his mid 90's F150 with spark plug issues and torque settings.
it happened as soon i chnge the oil their moral NEVERCHANGE THE OIL .......loll
I'm suspicious of those coils
I think the question is why did “the” 3.5L Ecoboost F-150 fail? It might not have failed Ford but IMHO it certainly failed the automotive buying public.
did you pull that piston yet? I gotta wonder if 'just changed the oil' included air filter and FOD from something got sucked in- a small screw/chunk of cardboard/anything coulda got inhaled, pinched between piston/head, rocking piston, breaking skirt off opposite side...if so some damage to opposite piston crown should be visible...never heard of a skirt failing like that...interesting. suggest cheap rebuild- one new piston maybe a hone job on that hole, should be fine, long as filter didnt bypass, blowing ring bits into journals
I really need a Timing Job done on my 2011 F150. I just can't bring myself to do it again right now. I have already done it once and money is just too tight right now.
من الغريب جداً عدم وجود ضعف في المحرك او اهتزاز المحرك، برغم ان هناك كسور في المقبض
Change the oil change oil at 3000 miles not Fords internal clock. I've got a 2012 f150 ecoboost. Are u ready for the mils. 375,000 miles. Runs great only big repair is I did the timing chain and cam phasers a while back.
How many miles was on it?
Could just be a manufacturing defect, it happens in mass production. Hopefully he got some decent life out of it at least, I wonder how many miles.
Notice when you look under the hood of any of the “big 3”, it’s a mess; hoses and wires just stuffed together everywhere. Look at a Toyota or Nissan truck engine and things are routed differently. Made to actually last. Ford, Chevy, and Ram are built to just sell you a truck and then don’t care. Don’t believe me? Just try and get the dealership to fix anything under warranty. They act like they’re spending their own money. SMH…
I have a 2019 Expedition, 40k miles, making a similar tapping noise (as well as the cam phaser startup rattle), how to proceed?
I had my connecting rod nut let go on my 2014 3.5 ecoboost let go @89k
Lucky for me it was covered under a CPO warranty..Ford tried to deny me a full engine replacement but it ended up with a new Longblock..Ford dragged this repair out for 53 days..Im done with ford after this truck
I really like this guy, very informative. Watching his videos definitely keeps me away from any Ford products. I think he has good Job Security Specializing in Ford.
Sorry not sorry half my 6 cars are FoMoCo products and that ratio drops every year. I am a Ford guy to the bone but even I cannot bring myself to buy anything Ford after 2011. Just complete garbage. I replaced my trash Ranger with a Frontier. Up until 2 years ago I had FIVE vehicles and FOUR were Fords.
My 1999 F-150 with 200k and a 5.4 2v runs like a champ. Turbo charged engines have way more parts to fail and most 6 cylinder engines are not as good as a good ole V8. More parts mo problems.
Hi FTM, I suggested to Ford that they contact you and get your opinion on things Ford.
Engine is super clean
I had a Jeep 4.0 inline six that busted a piston skirt. Sounded just like that. I knew what your noise was instantly. I rebuilt the engine. That was the only thing wrong with it. Sounded like the old hydraulic lifter noise. Changed the oil regularly. It just happened. No idea why. Just like your customer's truck.
Catch Cans do not allow the oil to lubricate the top end! Stop putting catch Cans on. If they actually helped at all the manufacturer would install them. You're not an engineer so don't make changes you don't understand based on aftermarket nonsense.
Wow that comment is so wrong on so many levels it should be marked for misinformation.
@@FordTechMakuloco There is no data showing they work at all. As long as the egr system is running you will have a dirty motor anyways.
You mean the EGR function built into the VCT function?
Looks like metallurgy fault. When the piston was made, Maybe some porosity in the piston. Just bad luck. Kind of like the trans lines going to the cooler in the 6R80 transmission.
Bad design. OEM's want max power and min weight. Engine design suffers and so do vehicle owners.
Not oem’s epa.
Perhaps it was dropped before assembly and cracked; letting loose on the poor guy at X amount of miles 😢
I think it sounds like valve train noise because of the different pressures on the piston during the 4 strokes of a complete cycle, making it sound like it's camshaft speed.
I don't remember seeing this kind of failure on older 8 cylinder engines.
They don't make as much hp per cylinder and don't tow my 7k camper at elevations over 6,000 ft like an Ecoboost.
As much as I like to dog ford, the reality is that all manufacturers quality is going downhill. I have been a diesel mechanic for 36 years. I drive a gen 3 Cummins. There is no way I would buy a newer diesel with all the emissions problems they have.
damb clean engine for that, but every thing is made from the lowest bidder. bad piston from start,I have rejected parts before rebuilding engines and this is factory. QC obviously did't check that piston or it was dropped
He needs to change his own oil... He might have been Sabotage by the oil change places you never know. If that's the case..
The ford truck brand has become an overpowering cult. People keep buying these s....t boxes and dumping there money and heart in them.
