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!

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.

Can I just take a minute to thank you for all the effort you put into not only finding these engones (typo, but they're gone alright!), but also all the technicalities of actually making a video about the disassembly. That would be hard enough for some of us, but you make the video amusing too. :)

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.

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!

If your taking about the cyclone then clearly you’ve never owned a rwd and awd/fwd. have fun doing the water pump then

Watching vids like this explains why I have a profound respect for automotive technicians.

The tear down is half the process. I wouldn't have known where to start on a Ford V-6 until I saw your video. Thanks for a complete, Every Nut and Bolt, Wiring Harness Connection and even some mechanical know how for the inevitable fastener issue. TORX head. Thanks for being straight forward and not having a "know it all" attitude. Just observing is a pleasure. This gets me interested in the complexity of the modern engines. I'm a SBC 70's era guy coming out of retirement interested in current power plants. If your other videos are this complete, your helping a lot of us Gearheads. Thanks again.

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.

Likely the most valuable part of that engine, intact injector plugs are worth money as replacement parts when they break. This engine likely lots of idle, and really long oil change intervals, and the final straw likely wearing bearings from poor oil pressure, then the crank breaking from a sharp edge left in manufacture, or a flaw in the steel casting.

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.

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.

Great Video, shared this with my good buddy who has a similar Ecoboost 3.5l.

Our Ecoboost just blew. This was helpful to see what could go wrong. This was crazy. Nice job.

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.

The pro mechanic that worked on it beat the crankpulley back on with a hammer like a hack and cracked the crankshaft... it was just a ticking time 💣... I'll bet money !!

As an Ecoboost 3.5L owner in a F150 I can say that if you change your oil often and keep up on all of the required maintenance these engines are long lived. Mine has 157K on it and runs like new. However they do not tolerate neglectful owners.

Agreed. I love mine. I had the notorious oil leak from the vacuum pump but other than that it's been great. Even that I did myself for 150 bucks. Good oil every 5k or less. Oil is cheap. Engines are not.

I could listen to this guy for ever! 24/7

Thanks for explaining the motor's breakdown. I know nothing about car engines, but I learned a ton from this video. Thank you again.

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 KZread 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 KZread. 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!

The flats on the cams are for a timing tool that holds both cams in place for timing services

While watching you tear down this engine a random thought ran through my mind. For some reason I would like to see you make a Halloween episode. Where you systematically tear down and creatively destroy every part as you go. Using such proper tools as saws , grinders, hammers, hydraulic press and whatever else seems fun. Just treat everything like a water pump. Put on a monster costume and have fun with it. While laughing maniacally. Just a thought. Hmmmm.

25:00, I like how you used your Special Cam Tool to remove the oil filter. Great Content, Thank You

10:07 I like when the rattle gun sounds like a laser pistol!

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.

I LOVE YOUR CHANNEL!!!!! Every Wednesday and Saturday night I look so forward to watching your teardowns. My mom and I used to watch your every episode, and now that she's gone I watch and remember how she would laugh at your jokes and your water pump shenanigans. I have learned a lot about engines from watching you and have laughed so hard at some of your exploits like "safety tote" and burying and running over "perfectly good" water pumps. I have a joke for you about the crankshaft on this one~It's a new feature Ford is trying, Bluetooth crankshafts. Love your new Ford slogan too by the way. Keep them coming Eric.

I had the same thing happen to a European Ford V4 back in 1978 . Started it one morning and bang ,no warning ,just bang . Once i got it disassembled i could see it had been cracked for some time before it let go. Ford quality is some where around JOB 96.

Oh gee, we changed the oil every 30,000 miles, give or take.

You changed the oil ???

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.

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.

I liked the video. Especially the complete take down of all the parts that need to be removed to get to the next component.

An excellent video. I am glad I found your KZread channel.

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.

Dude how tall are you ??????????????

Thanks for the video!

LOVE this channel. It's like a murder/mystery!

That was very interesting. Thanks for the video.

I had a customer come in with a beetle that ran perfectly until you lifted up on the throttle then BAM BAM BAM.... Crank was broken just like this one. Crazy that it still ran well.

I watch these vids with my kids and the dog. The kids star out enthusiastic but soon get bored and move on but the dog stays and gets real interested, triggering on any unusual noise. When you got to the busted crank he stood up, walked to the TV and barked. Recon he was saying, I knew that was a busted crank. Smart mut.

IVE BEEN WAITING FOR YOU TO DO A GEN 2 3.5!!! 🎉🎉🎉🎉🎉🎉🎉🎉🎉

Thanks! Good discoveries!

You wiggled that crank and I channeled Eric O, "There's your problem, lady." Catastrophe!

Great video. Appreciate it.

Secondary crankshaft.... love it.

A catch can works wonders. I installed one on my 2014 F-150 3.5 ecoboost after about 15,000 miles because of carbon issues. Never had another problem with stumbling, stuttering, and No cam phasers issues ever. I emptied the catch can about every other fuel fill up….about 1,000 miles. It was nasty gas, oil, and water usually.

Woah!!! What kind of force did that take to break the crank there. I was expecting it to have snapped under one of the rods. Never a shortage of interesting finds on this channel. Well done Eric!! 👍👍

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.

Thank you for this information video very interesting!

243k on my 1st gen 3.5 ecoboost. Original timing chain and guides, turbos. Waterpump changed at 190k , a couple cop rebuilds. Its been tuned since new also

Like your sense of humour nice and dry , a clean break all the way through. Could be a metal flaw and possible a forging issue . Amazing video one we don't see much of . Thanks Eric

Great informative video, thank you sir

Been sharing these videos with a friend across the country and he's loving them. This video got us into a whole discussion where he thought EcoBoost meant diesel and it was a teaching moment (think he was crossing Ford EcoBoost with RAM EcoDiesel; anyway) but that got us into a whole diesel conversation and made me think...wonder if you can ever get your hands on a VW/Audi V10 TDI!? Super rare I'm sure but would be epic!
