2019 Ford F-150 3.5L Ecoboost MAJOR ENGINE FAILURE! Full Teardown W/

For parts Email us at [e-mail] or visit www.Importapart.com!
Here's weekly dose of your catastrophic engine forensics! Every week you can find a new teardown of some abused, misused and/or poorly designed engine. Here are some of my favorites:
GM Vortex 8100 • LOCKED UP BIG BLOCK 8....
F150 5.0 Coyote Gen 1 • 11-14 Ford F150 5.0L C...
8.0L Ram V10 • 8 LITERS OF DESTRUCTIO...
Audi V10 • DEVASTATED Audi S6 5.2...
Today's teardown is a WILD one! This is the 3.5L Twin turbo Ecoboost V6 from a 2019 Ford F-150. This engine was a core return from a sold used engine, and unfortunately I do not know miles. It did still have the original plugs in it which Ford specifies to be changed every 100k miles. In this video I tear this engine down completely to try to figure out what happened and WOW, I was NOT expecting this type of failure! I wonder if this is a common, or an acute type of failure?
Why am I doing this? My name is Eric and I own and run a full service auto salvage business called Importapart. Part of our model includes dismantling blown and bad engines to salvage the good parts to resell. We do not rebuild engines, merely supply parts to those who do.
I really hope you enjoyed this teardown, as always I love all of the comments, feedback and even the criticism. Catch you on the next one!

Been at a Ford dealer in parts for 23 years. We do ALLOT of 3.5 Eco repairs. But NEVER any lower end failure, even on the N/A FWD 3.5 with water pump failures, I bet we've only done 2-3 engines due to coolant puking in to the crankcase. And I love the comment sections lol... POS Ecoboosts... We've seen many first gen with well over 300k on them, with maybe a chain replacement. When they're well maintained they will live. Eventually turbos will fail, tell me a turbo engine where they dont? On the other hand, no matter how well you maintain your Hemi, it will wipe a cam. No matter how well you maintain your GM LS with AFM, they will fail. Thanks again Eric for an awesome vid of epic engine failure!

[@pkt1213]

The addition of turbos, afm, and all sorts of tricks to meet mileage requirements. I was looking at used full size SUVs the other day and all the Fords had 3.5 ecoboosts in them. I ruled them out because I just don't trust buying a used turbo car for a daily. I bought a V8 Toyota with 230k instead. 😂 But those are all coming with twin turbo V6s now too.

[@garrettlombardi443]

Sadly your correct about the hemi and LS with afm but im a huge believer in maintenance it will treat you well most engine failures are due to daglect

[@pkt1213]

@garrettlombardi443 very true. My 230k toyota came with a stack of maintenance records. Also who I felt was a very honest seller trying to nitpick every little thing wrong, like I do. Both of my other cars have a logbook of everything, even every gallon of gas that has gone in. I would probably buy from someone like that. Adding turbos, IMO, just added complexity and additional parts to eventually fail.

[@rustbeltrobclassic2512]

That's why i prefer v8 toyota.. don't have these expensive issues..

[@pkt1213]

At least the UZ series are about the most reliable engines I have ever used. The URs are about as good. Although the belt drive 4.2 in my Audi is stupid solid too, just parts are more expensive to NLA. LS motors without active fuel management are dead reliable as well.

[@RobertSmith-le8wp]

My Dads 2012 King Ranch F150 5.0 cracked 3 pistons at 92,000 miles so it happens to all the engine options. I know a lot of people say the Coyote is the best option but who knows. My Dad is 70 years old and absolutely babied it and always changed the oil at 4k-5k intervals. I’ve seen some of the 3.5 ecoboost engines hit 500,000 miles so maybe it just depends on whether it was built on a Wednesday or a Friday

[@gernotritzau5948]

I would say, the Monday engine is probably the worst one, when they are still hung over from the weekend...

[@Powerstroke98]

Yes, I've heard many Gen1 engines coming out with high miles now, some having had to do the phaser/timing chains, but many haven't as well. I'm your dad's age, and I drive my 3.5 Eb for mileage, and every once in a while getting the turbo's to spin up good, but not very often. I do have a catch-can on my truck, and I'm surprised at the gunk that I pour out of it, so I'm somewhat hoping it's keeping the internals a little cleaner at least. With today's labour rate at the dealer, or even outside mechanics that know their stuff, it amazes me how much it costs to work on a six cylinder engine, but the 'fix-it' is still cheaper than upgrading the truck 'if' the truck is kept in good shape. Mine is paid for, so I feel fortunate it runs great, and will keep me maintaining it well of course!

[@jerryscott9598]

That was hilarious when I saw him do that!!

[@speed150mph]

I’m kinda proud that I figured out that the crank was broken within the first couple minutes of the tear down though I had to rewind a couple times to know I wasn’t crazy. If you look when he turned it over you can see the wobble in the damper as he overcomes the compression/ bind. Anyways, I took a failure analysis course on engines from caterpillar, and they spent a lot of time teaching us fracture patterns. The thing about fractures like this is they always generally start at stress risers. In this case, the fillet of the rod journal. If you look closely, there is a very smooth oval spot right at the edge of the brake where it meets the journal. This is the origin of a fatigue crack beginning at that stress riser and slowly working its way though. The crack reached a point where the structural integrity of the crank could no longer hold up to normal cyclic loads, and the crank began to transition from a fatigue crack into a brittle fracture with chevrons pointing towards the origin. This part of the failure rapidly accelerated until it finally snapped the remaining material. With only the front bearing supporting the front section of crank, it was free to move a large amount, exasperated by the loads placed on the nose by the timing chain and accessory drive belt. This movement was enough to overload the bearing, forcing it to spin, as well as damaging the oil pump thrust faces and breaking the chain guides.

[@AryelExMachina]

I'm glad I'm not the only one! The crank was noticeably off from the first rotation. Then the destroyed crank seal.. crank nose off centre in the timing cover.. I was shouting LOOK AT THE CRANK!! by 12:50, had to check the comments to see if anyone else had seen it too >.< .. Loving every minute of your content Eric!

@@ElectricSwordfish it really was. There was a lot of theory, but it got really interesting when they would bring out piles of broken parts that were turned in and we had to try and figure out what happened, what the root cause of the failure and what was collateral damage.

[@geobrower3069]

Great analysis, I wonder how long the engine was run after the crank failed. Amazing that the engine was still in tune!

[@speed150mph]

@@geobrower3069I estimate a couple minutes max. The engine ran long enough for it to machine down and spin the bearing, and for that material to make it into the oil filter, but not long enough after the bearing spun for heat to build up in the main cap or for the corresponding rod bearings to be damaged by a lack of lubrication.

[@MilitaryTalkGuy]

ford hate aside, my 2015 F150 has the 3.5ecoboost and it has been a rock solid motor for 140k and counting. The icing on the cake for me is the mileage. I get an honest 21mpg highway if I keep it to 70mph. My last F150 had the V8 and it only got 17mph although that engine was also rock solid. So over the life of my current truck, I have saved quite a bit on gas cost. I'd get another 3.5ecoboost any time. If you keep your fluids changed regularly, they are great engines.

[@Old940]

Trade my 14 F150 with 5.0 for a GMC 6.2 and get better gas mileage. But if you spend 70 plus for a vehicle and have to worry about the gas mileage you best stay home. Bought a 78 F250 with a 400 auto trans and got 12 to maybe 16 on the road at 60, and have had Ford Motor vehicle until I just got this 24 GMC just because Ford Dealerships did not want to deal.

Other maintenance Both front wheel bearings, rear shocks twice, and front brakes only. Have the service records to prove it. Still has every original light bulb in it.

[@doityourdarnedself]

How often do you change your oil?

[@richallen8742]

@doityourdarnedself as I stated above, this is a work truck, part of our fleet. We do not follow any scheduled maintenance other than recommended by the manufacturer, but we are asked to care for them as if they are our own vehicles. Oil changes I try to due at or around the 5K mark. Which is usually 4.5 - 5 weeks. The meter in the vehicle will say 77% oil life left??? I question that, This past Sat 4/6, the front and rear diffs were both serviced as well as the transfer case. Both diffs had the original gear oil since new, and so did the T-case. Diffs were very bad being original. T case was sampled and still generally clear fluid but changed anyhow.

[@ajgorney]

Similar story. 2017 3.5 with 310,000 miles. Always complete routine maintenance. lots of easy highway miles, don't drive it hard without need, plug changes every 60-80K or so, one new set of coils. The cats are shot now but I'm not in an emissions check area. Don't gun it and rev the turbos more than needed routinely, it will last.

[@Powerstroke98]

@@ajgorney After watching a few KZbin video's on the CATS, once they get plugged up, your fuel mileage will suffer greatly apparently, as the fuel to air mixture is thrown off, so the computer throws more fuel than needed. I saw one cat after being pulled, that had large chunks fall on the floor from the CAT, and they aren't excessively expensive. Just sayin', as I'm at 137K and I got my first check engine light, and the code was for the 02 sensor in the bank 2 catalytic converter. You can check by testing the heat going IN and OUT of the cat, where it should be hotter coming OUT, than going in.

[@fargenvonwitbier]

Dealer tech here: yeah unfortunatel this is becomign a decently common thing with these second gen 3.5 EBs.

Even had one where the thrust bearing left the chat and the crank had way too much endplay.

Likely the most valuable part of that engine, intact injector plugs are worth money as replacement parts when they break.

I thought this was the case when I saw you rotate the engine over. The left side timing chain guide moved in and out. Similar to a stretched chain. I love your videos. Thanks for your time

I had an ‘86 S10 blazer. 2.8L. It had a broken crank for what turned out to be over a year. First sign was the oil pressure dropping when I stepped on the gas. I didn’t know what was wrong. Just kept driving it. I was on my way home from school one weekend when it started “knocking”. I started tearing it down and I could wiggle the balancer a lot. After I got it apart I found the crank broken right in front of the second main bearing. It ran just fine but there were pieces of steel in pan the size of rice grains. No tunes or turbos. Just pure GM 2.8 power.

[@Pheonixco]

These engines are a shitshow, had a former coworker that had to take his new at the time F150 in 3 times in a matter of month because of various issues, and ended up trading it in a year later as they never were completely solved. I will say I appreciate you taking the time to unlatch the wiring harness on it, most of the used engines I come across, the yards just snip all of it off, which is a waste.

During my working life I only ever encountered 2 broken crankshafts. Number one was a Leyland diesel bus engine which lay on its side under the vehicle, it probably had done a million and a half miles for the Brisbane City Council, Queensland Australia. Bought by my employer very well used, no known reason for it to break. Number two was a Mazda 3500 diesel bus owned by the school I worked at in the 80s and 90s again outer Brisbane. It was found to have a loose pulley Harmonic balancer, I tightened it up but it worked loose again, so I fitted a new pulley but the damage had already been done, soon after the driver phoned to say that her bus was making a bad noise. I having had experience with a Toyota diesel making a bad noise with a clogged injector, went out and checked it out, loosened off the injectors one at a time, the noise stropped as soon as I loosened number one. Swapped number one injector to another cylinder but the noise stayed with number one, on further examining I found the front pulley to be out about 3mm. I was able to fit a new crankshaft without removing the engine from the chassis. Ted from down under.

ERIC: You had made a comment about the intake port angle being too steep to see the intake valves. Might I suggest a "probe camera" for you. You know the one, carried by any auto store, looks like proctology equipment. Just video the screen of that puppy. Valves, pistons (or lack there of) with the head on, up the nose... the possibilities are endless. Keep up the awesome job. Cheers man.

Bummer! I have a 2019 3.5 Eco with 78K miles. So far so good. I'm also a freak about all maintenance, particularly oil changes. Full synthetic every 5K or before. Hope nothing like this doesn't happen to mine. Now I'll be thinking about this all the time!🤨

[@yodasbff3395]

Great teardown, thanks for sharing your videos. 👍

[@manonmars2009]

This engine looks like it did not have regular oil changes, the massive carbon build up on the pistons and the second compression ring that cemented itself to the piston implies that this was a hard working engine that just did not get a lot of regular attention. I agree, the crankshaft had a flaw....a big flaw to be sure.

[@t-yoonit]

8/10 speed transmissions + EGR + shit fuel quality and short drive cycles will cause that as well.

[@hdrenginedevelopment7507]

Usually stuck/carboned 2nd ring indicates poor quality top ring seal. More than likely it was babied too much at break in. I drove mine fairly hard without too much rpm from new like you would break in a fresh rebuild and it doesn't use a drop of oil between 5k mile oil changes. It also gets the piss driven out of it daily. Most engines maintain much better ring seal with harder use, especially now with the thinner low tension rings. The combustion pressure helps push the top ring into the cylinder wall harder, which is super important when it is new and the cylinder still has some roughness to it from honing.

WAY back, I had a 283 in my old chevy, that I pulled out and rebuilt. It was a great experience, learning how everything comes apart, gets some new parts, some rebuilt, goes back together, and fires up again! Since that day, I've done most all of my own repairs and maintenance, and most often will check a KZbin video first, to have a clear grasp of things to watch for in doing a good job. I've gain a lot of tools over the years as well, so I feel fortunate now, having the ability and confidence to take on just about any job after seeing how it's done on KZbin. There's a few more tools that come make life easier, but I'm getting older now, and think it's time to hold up on buying more tools for the most part, and jobs 'under' the vehicle, I may be better off paying someone else. lol. I say this, after doing my oil change and fuel filters as well as a full lube job on my diesel pusher motorhome!

[@larrypelrine1799]

Wow, how do you crack the balancers on the crankshaft? And more impressively, how do you not have the pistons turn into a family meal of piston mcnuggets?

[@jimmyaber5920]

The machining of the "pork chops" of the crank can be stress risers for a break point. Most cranks have that, but crank failures are rare. Aggressive programmer tunes can make for stress that breaks things, especially high boost at low revs.

[@kevinscott8694]

We ar a Ford Specialty shop. At the dealer for 10 years and had my own shop for 12 years now. We have a 2018 3.5l eco with the cab in the air now that I told the guy 2 years ago, NO aftermarket oil filter and NO more then 5-7k on the oil changes. I have not seen him in 2 years until it got towed in last week. Now 2 years and 60k later (its a work truck) and the inside wanted to be on the outside. Broke a #6 connecting rod, and the rod punched a hole in the Block. Hes been going to Valvoline, Jiffy lube for LOF's of course... The Mighty oil filter (Like most other aftermarket filters) on the engine you had torn down are to restrictive. They put to many pleats in the filter element which opens the bypass and basically puts the oiling system in 'limp mode' all the time. Like running around with no oil filter.. Lack of flow and no filtration equals bearing failure... 5w30 SN+ certified oil (Whatever brand you'd like) and a Motorcraft filter if you want your ecoboost bottom end to get to 500k.

4 years into owning my 2020 F150 and the gen two 3.5 has been flawless, with the exception of a crush washer leaking coolant on one of the turbos. Great fuel economy, stupid torque, not really that hard to work on. I added a Ford Performance catch can to try and keep the intake tract a bit cleaner, would've loved to see how the intake valves looked on this engine. I bought my truck with the intention to own it as long as possible so I'm hopeful it won't need an engine replacement for a good long while, not sure if I'll be able to say the same about the 10R, but time will tell. At the very least I know I won't have to worry about the cab and bed rusting out from all of the salty midwest winters we have :) The gen three 3.5 is pretty similar to the gen two, I think both are considerably better than the gen one in many regards (better valvetrain design, beefier timing components, oil squirters, port injection, better rod and piston). The gen three gets a bit more complex because Ford added an EGR system including an EGR cooler to the gen three (similar to the 2.7) which I'm willing to bet will be a problem point once those trucks start getting into higher mileages. Midway through production (par for the course with Ford) they also changed the spark plugs on the gen three to an indexed plug that uses a flat washer seat instead of a tapered seat which I'm sure will lead to confusion in coming years.

[@davewilkirson2320]

I have seen a few of your teardowns. Great job you do. A 2020 Explorer 3.5 was the beginning of my divorce. Nothing but trouble. Electrical trouble. I'm an electrical engineer. One of those book nerds (retired). One of my hobbies is or was rebuilding small blocks for my Camaros and Vettes. Mostly Chevy 283s and 350s and a few 454s. But I never found a broken crank. However, with Ford, I found many tiny, little gauge wires, that feed various components, such as the fuel pump, to be...well...too tiny (and melted). The wifey was eventually in Dallas traffic and the vehicle stopped running. She blammed me, as some wives will do. Divorce aside I am happier these days with the Ford and wife gone. However, I must say, I will never, never, never go back to Ford. I was a believer of Ford in the 1960's. Great 6 cylinder pickup trucks with Charles Bronson ads about the toughness of Ford. Heck, one ad was an F-150 pulling a 747. Ford's 302, 351, 390, motors were great. The FE engines were great. The crap Ford creates today is.....crap. That crank appeared, in your video, to be porous cast iron with the strength of a cedar tree. And to think Ford won Le Mans in 1966 with the GT40 surprises the hell outta me. I suppose Shelby had a hand in it. But, I was 9 that year and Ford was good.

Those rings! I've been reducing the oil change intervals on my 2.7L F-150 more & more. I'm currently down to 4k mile oil changes. After seeing this, it just became 3500!

[@rmkilc]

Any modern engine needs 3k-4k oil change intervals no matter what the manufacturer says. Between the tiny clearances, the small pathways in the VVT solenoids, etc. it is a must. Throw in direct injection and/or turbos, and it's downright required. I guarantee most of these failures would go away if people would just change their oil.

[@amschind]

The gen 2 3.5 is a solid engine. First, the 3.5 EB out of a stock F150 was a Le Mans engine 20 years ago, save for the forged steel rods vs aluminum in the racing application (where longevity means 24 hours). A tuned version of the 3.5 STILL IS a Le Mans engine. It is an absolute monster, and the few weak points are gone since 2021 (phasers finally fixed, chain stretch, intake ports, turbo cooling, et c). It has oil and water cooled turbos. It has a forged 4340 crank and forged con rods. It has monstrous 6 bolt main bearings. The only major remaining shortcomings are the exhaust manifolds that would be at home on a model T and Ford moving back to EGR. It is a racecar engine, and if you treat it like a beater Toyota, you will kill it, exactly like the yahoos who destroyed the truck above. Tolerance of abuse is only a virtue for the foolish and irresponsible; such people are better served with the cheapest vehicles that they are willing to tolerate.
