Every week I release a new video tearing down a blown up, core, or thought to be bad engine. I don't always get details on why, what, miles, etc, but we always tear them down to try to figure those questions out.
Here are a few of my favorites!
Escalade 6.2L L86 V8 W/Major Damage • EXPLODED! GM 6.2L LT1/...
Ford 1.0L Ecoboost, The Lawsuit failure: • JUNK Ford Ecosport 1.0...
F150 3.5L Ecoboost Catastrophic failure • 2019 Ford F-150 3.5L E...
How do you blow up a Prius!? • BLEW UP A PRIUS?! 2010...
Today's subject is a VERY destroyed Ford 2.0L Ecoboost from a 2014 Escape titanium with 164k miles. Its quite clear this engine needed replacement, with massive holes and damage throughout, but why did it fail the way it did?I've been doing this for quite some time and its rare that I run across an engine without a clear reason for failure. So why do you think this failed? What was the cause? Let me know in the comments!
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 up, bad, and failed engines to salvage the good parts for resale. We do not rebuild or fix engines, merely supply parts to those that 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!

Why do you think that your mildly amusing? you are really not!
Who said I'm amusing?
@@I_Do_Cars I do, I laugh at your waterpump antics every time!!
@@I_Do_Cars I do.
Nobody is forcing you to watch.
He's not mildly amusing, he's **extremely** amusing.
I think you had a metallurgical failure, freeze at 23:51 where you have the two rod halves in hand. The bottom one, look at the split on the right; it comes in from the outside, and it's not shiny. Then it kind of crests, and there's an abrupt transition into shiny metal. That's a traveling fracture. Basically the rod broke in "greenstick" fashion and stretched enough while it was doing it to hammer the piston into the head.
Still ecofail
I think you are correct. It's the only way the piston makes contact while having a good rod bearing.
By Jove, that's _just_ what _I_ was about to think!
But seriously, when it turned out that the #4 big-end bearing was good, I immediately thought of a "rod-stretcher" event like overrevving on a downshift or a missed upshift.
@@OgamiItto70 but it was in a Flex, so no manual transmission.
@@socmonki That's right. It had an automatic money shift machine bolted to it. hehe. But no seriously it is possible for these modern transmissions to "money shift" if it fails to shift the right way at high rpm. Certainly not a common occurrence and far more likely to happen to something like a 10r80 but still possible.
I love how they considerately included a rebuild kit inside the oil pan for you. It's like a spare tire for your engine!
These are Mazda based engines, hence the black plastic; Any questions?
I laughed way too hard at that 😅 Great way to put it 💯👍🏻
😆😂
@flies don't be Mazda fanboy
I've learned so much from this channel. This is by far, my most favorite channel ever.
Same here. He's taught me so much about engines and what their common failure points are. Plus, it's interesting the different ways people could completely destroy them
I’ve learned the importance of checking and changing my oil
@@rleger123 Yet the vast majority won't 😮💨
Yep never ever buy Ford sh!te.
Almost died laughing when you reached into the bore and grabbed your 10mm socket through the hole in the block!
Right! I couldn't stop laughing when I saw him reaching out to grab the socket through the gaping hole.
The waterpump removal...fu*king brutal...LOVED IT!
Dude I have to know each week, what's gonna happen to the waterpump! 🤣
Should see what I have to do to remove them in vehicle when their that stuck 😂
Based on the fact that the wrist pin is pristine, which it would not be had the piston failed first, my guess is going to be that the rod failed first. Not the bearing, *the rod*. I'd have to put the fragments under a magnifier to spot the fracture point, but I'm confident that the rod had to have failed first, and then the remainder of it bludgeoned the rest. This kind of failure was essentially unknown in engines of the past, but I see them happening more often as time goes on. I blame the engineers' reliance on materials perfection and the relentless drive for reduction in mass (with the goal of increased "efficiency") as the source of this tendency toward failures. As for why this specific engine failed, perhaps over-revving might have been involved,. but if the seminal failure point shows stairstepped fracturing, then the final-failure break could have taken place at almost any speed.
I agree, this seems like a material defect in the rod -- an inclusion that weakened the rod. A key clue here is the longitudinal fracture through the thinner part of the rod -- I have never seen that type of failure before.
Pre-ignition could have done the piston and rod in at the same time with lateral forces, but I’m with you: that piston split and the rest is collateral damage.
Exelente lo suyo señor 👏 👏, bielas de material sinterizado con escaso margen de seguridad, antes a los motores se les daba un poco más de robustez por las dudas, hoy todo se calcula al mm..... y puede fallar
just an other example of how cheap and incompetent car manufactures are getting. its all about making a dollar and cars have become disposable now . drive 3-5 years car dies buy new one dealer makes more money! remember when we used to drive cars for like 20 years? now your lucky if u get 5 years
@@somejoe7777 I agree.
I think it was a parts failure! I think the connecting rod failed first. Look at the way the rod fractured. Engine looks well maintained and no sign of coolant intrusion either!
Ecofail
The early 2.0s didn't have the intrusion issue. The 2015 and up Escape did, because of a redesign in the cooling system. Why they redesigned it? No idea. Should have just kept the original design. 264k still going strong in my ST.
Nothing like an order of piston nuggets with a side of wrist pin on a Saturday night
‘Not fully hatched’ 😂
Water pump subtlety…your true gift Eric! We need a tragic water pump opera music suite. Great job Eric.
He was being gentle the entire time. Sucks that the pump is so fragile

I think Eric was bullied by a water pump in the school yard in 3rd grade. Never forgave them
You broke it! Now how will you sell it?!
Ecoboost engine's make the most impressive sudden engine disassembly kits on the market!!!
They’ve just been doing it the longest. Toyota and Ram, particularly Ram, are making strides. I bet the 500 hp 3.0 SST will do a great job ejecting wrist pins
I have built/stripped engines for 50 years and I love watching you strip engines. Your production skills using time lapse are excellent integrating comments, love it. I also like reading the comments from the "desktop mechanics", they don't even know how obvious they are.
Keep up the good videos!
When the 3.5l EcoBoom blew at 19k miles on my 2013 F150, the bearing was perfect. I bought it brand new and always changed the oil religiously. Always used Amsoil in it.
The rods Ford uses are weak. Think it’s the same rods used in a Briggs and Stratton.
My lawn mower just got insulted 😂
The con rod in my garden tractor is 4-5 times thicker than that ferd's ever were 😂😂😂😅😊
@@johnathanedwards9054 They're saving weight. After all it is an ECO engine don't cha know?! One of them thar turbolated racer enjines.
It seems like you either get a really good one or a really bad one, not much in the middle with those engines.
You definitely did something wrong
I am not sure if they changed something but my 3.5 2020 F150 is 96K and didn't have any issues except some electrical stuff
Doing your maintenance prevents you from having a huge ass bill in the end
When (if) a wrist pin deforms in ANY way, the piston stops pivoting on the pin & the piston from pin bore up gets yanked away from the bottom of the piston. This happened to the SuperStock AMXs back in the late 60s early 70s when the wrist pins went oval at high Rs (stock rods & cranks are forged steel, 8500 RPM capable). Fix was tool steel .200" wall pins. I got mine from JE for $200 in the previous century...
Any chance of you recording the conversation between you and your tool vendor when you request a warranty on one of your tools? "Hey, it's a lifetime warranty, right? I'm still alive, ain't I?"
Due to the lack of bore damage, that Conrod failed first. Piston to head contact is key here. Bearings are fine, no excessive wear on the wrist pin or bores. Only thing I can think of that could cause piston to head contact like that is rod stretch at high rpm. If that rod isn’t cast, hardened, and tempered properly, it may not have had the tensile strength to hold up long term to the stresses leading to a fatigue failure. Luckily cylinder 2 seems to be suffering a similar fate but stayed intact. It would be nice to see a closer look at it, and measure it to see if there’s any distortion in the rod itself.
Also, maybe injector stuck open? caused the cylinder to fill up with high pressure fuel, when the piston came back around it tried to compress against 1/4" solid and the conrod exploded down the middle, probably sounded like a HUGE knock. Then on the way down it ripped to shreds.
@@th3R0b0t that wouldn’t have caused the piston to head contact.
@@speed150mph yes, you are right...
Looking back at the head now. This is a crazy what-if... but it could almost make sense(since rod stretch was occurring on 4 and 2), 4 hit the head several times. What IF, that transferred into crushing part of that injector via the head crush and dumped fuel?
I know that's an extremely low probability.
Most likely (this is how I interpreted your OP), the rod stretched out, and the piston smacking the head would compress the rod back, and if we're talking weak rods, it probably started stress fracturing right then. You could test the thickness of the rod bearing and see if it shows sign of compression at it's peak.
But it probably filled itself with hairlines, and a few revs later, tore itself to pieces and swiped the inside of the block.
Why does conrod have a capital C ??
18:11 This was priceless! I had to laugh - the milk almost squirted out the nose! Love this method of removing the water pump! Thanks for the laugh!!!
Don't feel stumped; it's a FORD! Built to eventually break. OH, just replace the motor. No more problem.
Split connecting rod shouldn't happen. Slight flaw in the material combined with 164,oo0 miles and a high rev equals equals boom.
My only guess is the piston head cracked and let go, too much friction? Ran too lean? Engine lugging or detonation perhaps? It doesn't look like a super high RPM explosion. I don't think it was an oiling failure it looks more like a defective piston rod/head or a bad air fuel mix for an extended period of time. It could also be possible the wrist pin or some of the control rings seized up, but the lack of cylinder wear kinda indicates otherwise.
I lean on the side of weak piston head mixed with detonation, turbocharged it's high compression, it could have been cracked through bad driving habits and at a later point let go at a lower RPM, maybe the next warm up cycle. Maybe a defect in the cast that decided to finally rear its ugly head 160k in.
So nice that Ford provides a spare parts container underneath the engine.
Eric, you're just THE best man. I've been watching you for years. I never ever get tired of this.
The only thing besides a trashed rod bering I've seen that allows a piston to hit the head is trashed wrist pin bushings. If allowed to knock long enough they will hammer the piston to pieces. When the piston finally came apart the rod was free to fly around and destroy the block. Someone should have heard that knock they just ignored it.
What do you do with all those timing chains? I’m dying to know.
Mystery blow up is usually high water and hydrolock. It can be over revving from time to time.
I'm guessing LSPI (low speed pre-ignition) that small GDI turbo engines have experienced. They call it super-knock. Premature ignition shattered the rod and lower piston allowing it to kiss the head on compression stroke. Cause could be as simple as wrong oil. This condition is why the API developed the SP classification and reduced the calcium content.
I don't think this was anything the owner did. Over-revving the engine is a possibility but modern engines have rev limiters that kick in to prevent this exact thing from happening. Sure it can be bypassed but that's only possible with a manual transmission and not a lot of cars have those these days. There's little if any evidence that points to neglect. Normally with neglect you see things like chewed up camshaft lobes, sludge buildup and the rod and/or main bearings will absolutely be smoked if the neglect was bad enough to cause total engine failure. Instead they're all in perfect condition even in the cylinder that grenaded itself. This leads me to my one and only remaining sound conclusion: that the engine blew up due to a factory defect. The way the rod broke (something I've never seen before) is what points to this. My theory is that the stress of normal engine use eventually exposed a weak point in the rod and caused it to break. With the rod broken, the piston struck the cylinder head causing it to break and shatter. The crank then pulled the shrapnel down with it causing it to saw its way through the engine block sending shrapnel and debris out the side and down into the oil pan.
It's the owners fault. The owner bought an ecofail
@@mann_idonotreadreplies I mean...you're not wrong 😂 this engine is a ticking time bomb if I ever saw one
After 164000 miles a sudden factory defect?...quit hating and be real .. hydrolock from some source much more likely
Nailed it! Every wrench turner laughed out loud when you "chased" the infamous 10mm deep well, LOL too good. Thanks.
I can’t imagine how the convo went in the ford engineering department when the new kid suggested keyless chain sprockets. Somehow he won the argument 🤯
That engine is based on a design from the early 2000’s when ford still owned a very large portion of Mazda. The engines were keyless then.
"We'll save 50c and one machining op per unit" .... "Well, you've sold me!"
My dad have none turbo 2.0 engine from Ford. I had 2.0 Ztec engine from the early years of focus.
In defense of the engineers, id wager it was the bean counters who said with the right jig we don’t need keys and can save 40 cents a unit
Jag used that forever.
That's not an oil PAN. That's a pinyata.🎉😮
Thank you so much for removing the water pump the correct way, by smashing it off...
Whenever you get a engine with holes, water pumps need to be removed this way as it makes fantastic viewing...
I really enjoy your videos and what you do... Thank you so much.
High speed catastrophic event by rod or piston breakage.
The snap sound of torqued screws loosening is sooo satisfying, it's always the best part😂
someone paid thousands of dollars for that junk at one time.
Another Ecoboom doing what Ecobooms do best.
When are people going to learn. Ford has never and will never build a decent turbo engine
the "Terminator " hammer and later the angle grinder to persuade the rod bolt, priceless!
"If you take the crank pulley off, you have to retime it!"
Heavens forbid they index the crank pulley and have timing marks...
Looks like a fatigue issue or perhaps a flaw or void in the rod, and that perpetuated a crack that became a boom. In the days before rev-limiters, rods would let go by over-rev and do the same type of damage you have there.
I had one of those come in in a Range Rover Discovery Sport that died on the road I found a broken/ stretched Bolt that was meant to retain the Intake cam phaser to the camshaft, scoped all the cylinders, found no valve marks on the pistons and all the valves moved freely. All new timing set from Ford, plus the timing tool kit as there are no keyways holding the sprockets in time. Engine fired right up and the customer was happy we were able to save his engine for less than 20% of the Range Rover Dealer quote.
Looks like the owner took very good care of that Escape. No carbon build up or oil sludge. And she still blew at 160K
Having a good old time with blue! Great video for my Saturday night
I think that the broken rod had a flaw put in it when it was made, as indicated by the split. Instead of pushing the piston up while connected to the wrist pin, it pushed up on the skirt instead and pushed into the head, where it broke apart, falling into the block. This is a material failure, not anything else, in my humble and not expert opinion.
Over 100 yrs of engine building and things are worse than ever. Turbo disposable Trash motors. Ford and all the manufacturers are building Disposable Trash on purpose. I haventbought a new vehicle since 2004 and no intentions ever again. To expensive and pure outsourced Trsdh. In my 62 yrs I've owned 34 vehicles. 6-7 Brand new.Never had an engine failure cause i always bought vehicles thst have great Longevity records. Ill keep my current 1996 Buick Lesebre with 132k forever.
Small displacement forcing induction!!
To make usable/ daily use power.
Manufacturers are forced to meet government regulations, while trying to keep customers base happy.
Can you please just give the federal government the middle finger, give us bigger displacement, with less mpg?
I’ll take that every day!!!
Exactly why I just purchased a v 8
Mustang.
I would guess that there probably isn't a whole lot of demand for this engine "per se", but have you seen or came across any 2017-2022 GM 3.6l LGZ motors by chance? Those were in the Chevy Colorados and GMC Canyons for those as mentiomed. I know they likely have some architecture similarity as the LLT's, LFX's, and (other 3.6l GM engines not aforementioned). Im just curious as to if anyone has happened to replace one yet. From as far as I know, they have similar issues as to timing problems and the good ol' GM Tick.
Same engine that land rover used. Turbo, Turbo, Turbo.... intake cam VVT actuator failure. Rinse repeat. Been hating ford since the early 90s
Just a slight crack on side 1 , a bit of jb weld ( and top ramen ) it'll be good as new 👌🏻
Will never buy another Ford ever again, low compression on a 2.0 ecoboost ST engine after 63k miles and Castrol oil changes every 4k. Shockingly under-engineered.
I would suggest doing a dye-pen or macro acid-etch of a cross section of the rods. Basically cut it in two, polish it up real nice, and look for cracks/porosity/metalurgical problems. Because metallurgy is the only way I can see something suddenly failing like that, short of hydrolock or something. Maybe the rods started to stretch over the years, and it struck the head hard enough to crack.
I have a fusion with the 1.5 eco I get nervous flooring it because I’m afraid the engine might explode 😂, think my next car is gonna be a crown Victoria because 4.6 reliability
Due to coriolis force in the northern hemisphere, you should always turn your engines over clockwise, seen from the accessory end of the engine. That is why they spin this way, with the exception of some odd Honda engines.
I have a 2017 2.5L that just crapped out, turns out it was number 3 piston oil scraper crapped out scoured side of cylinder, the entire rest on the motor looked like new, 77k miles😢
Turn the vice grips around and put them on properly. You were putting them on backwards. Vice grips work better when you turn on the other way just like a pipe wrench.
I see this so often but give the guy a break ,he is not a mechanic ,more of a destructor reconstructor
@@davidkettell1073 And vise grips aren't usually part of the rod removal process...
Escape Titanium? Only if that's what the rod was made of (though maybe it wouldn't have escaped if it had been made of titanium).
Does Mommy and Daddy have a Teenaged Son who thinks he’s Ricky Racer? OK boys and girls… can you say… Over Rev?
I had a focus at with this pile of shit engine. Blew ring lands at 35k miles on number 4. I guess the crankshaft flexing usually means number 4 is the one that blows on these. Looks like it still the same lol. This is and will ever be the last new Ford I buy.
My carnal thirst for mechanical destruction can never be sated.
Don't judge me. 😊

And lo Jesus said unto his people. "Change your oil regularly."
There’s one mystery which remains unrevealed (unless I missed it…. =/). We all know the water pumps and chain guides end their days via rapid forced disassembly or binning, wrist pins have infinite life, but what happens to the cam drive chains? There’s always a compliment offered regarding their condition (uniformly excellent), then… nothing. They just… disappear… with nary a mention, nothing to see here.
Everybody wants to know - what happens to the chains???
They are gold plated, and sold... TO RAP ARTISTS.
I asked a couple of times, no one answered, I even searched the internet "chain meme" etc. to no avail.. A mystery ;D
I bet Eric is using them to build a throne, like the one in "Game of Thrones", except it's made of cam drive chains. Somebody tell me I'm wrong!
I'd assume they wind up in the bin much like the water pumps and guides, no resale value on a stretched chain. Only other thing would be their own bin if the scrap dealer is willing to purchase separately if they are some specific alloy.
The crank turn was genius this week. Loved the view from the crankcase “window”
I got rid of a 2014 Ford Escape with the 2.0 ecoboost. En%I expected issues.

Crap… I got 70k on my 2.3 Mustang before it started sucking coolant.
Just finished replacing one of these engines in a 2016 Edge with 64K for coolant intrusion into the cylinder. Looks like a broken piston on this one. Rocket Sockets will help with bolts like the rod bolts on this one.
SAD
If the coolant intrusion is found early, do you think a new head gasket could solve the problem?
2 liter eco boost. I’m surprised Ford didn’t put that into an F-350.
10:15 That, alone, would guarantee I never buy a car with this engine in it. I HATE that sort of anti-shadetree andi-third-party special-tools-required bullshit.
Yes, the rod failed, here's what I think factory defect, it fragged when the piston was on it's way up allowing the piston to hit the head
Now that it's officially a 3 cylinder engine, think it would work in a Fiat?
When I worked at a Ford Garage, had a 5.4 throw a rod, tore it down and I couldn't figure out why it threw a rod either, bearings were great, same with the cams, timing components were great, 2 valve so no phasers. I can only suspect it was some manufacturing issue.
It was an overrev. People think that you can't blow up an engine with an automatic trans because of the rev limiter---sure you can. If you're going down the highway and the trans goes into a low gear (either by mechanical failure of the trans or an oopsie), the torque converter or rev limiter won't save you---it's the auto trans version of a money shift. Thanks for the carnage, it's always appreciated
I love these videos but I was thinking that the power of JB-Weld is just unrated. Most of the parts could have been easily fixed.
😂😂 just kidding! 😂😂
Well there's no mystery there to solve that is what Ford's are best for, leaving motorist stranded.
I don't work on cars or in the industry. But, I watch a lot of videos on these types of things. My theory, from my armchair, is a metal fatigue / imperfection. Unless there is a way where FOD can enter the engine, IDK any other way this can fail.
That's just all the extra wear metals that Ford throws in to keep the engine running like new.
How do these engines keep failing like this while idling in the drive thru waiting for coffee?
Wow. Poor little engine huffed and puffed and blew itself up.
Wrist-pins rarely die, they just get launched into the great unknown...
And of course this all happened while idling at a stoplight on a Sunday afternoon trip to the grocery store.
fast food drive thru
That was one of the most generously filled party pans we've seen!
I actually laughed when the oil pan came off.
One of my old fleet 3.5 Ecoboost V6s ran low on oil (very quickly apparently) and did this. The driver said he turned it off immediately, got it back to find no holes in the block so we started taring it down to find 3 and 6 rod bearings bad, clearly a loss of oil issue, but interestingly the piston, wrist pin and about 1 inch of rod was up against the head in great shape, the rod had obliterated itself almost just like this between there and the crank.
I have a theory that it was a manufacturing issue with the considerable heating cycles the rod cracks then snaps, hammering the piston into the head. After a few combustion cycles the piston is non-existent and the rest is what we see, PARTY BOX
I'm an aviation engineer and metal fatigue cripples aircraft
You need to get a 22-24 Toyota 3.5 twin turbo v6. But I expect they are keeping them out of the hands of people like you. :D
It’s the most requested engine on the channel and all dealers are sending them back
Elvis has definitely left the engine.
Before watching fully, I'm betting the PCV got plugged up and caused over pressure in the crankcase...and now to watch & see if I was even close. 😁
Well I was close after all...too much crankcase pressure. 😅
I hope that engine was free, or better yet, someone paid you to take it.
Hey, I found a part my buddy was looking for on your website. I sent him a link.
Why? because it's a ford and engineered to fail.
Ecoboost engineer went on to design the Hatchimal toy.
18:45 I'll give you $30 for the water pump
Thanks for the Saturday Night Specials. 😃
My guess is it was run at redline for an extended period of time.
Could have been a casting defect on the piston rod.
Air hammer in tool list for water pump replacement, I learn stuff every day.
You should run an engine on a stand and drain the oil out and see how long it lasts.
Would make a great video.
Titanium? It had a good radio. Thst didnt make a noise. Probably didnt realize it til they got home. Awesome video brother
AHHHH! You RUINED that maincap by grinding on it.
I was going to get that, the tensioners, guides and timing chains along with the bearings and water pump.... JEEEEEEZ!!!
The only thing I can think of for a cause is that connecting rod on #4 had an "inclusion" in the steel. Combine that with the mileage and you end up with a fatigue failure and they kept on driving in spite of the clattering it was making.
Ha! Eric! I have European ecoboost 2.0T in RR Evoque with total malice in cylinder 4. Piston broke and uncle Rodney got ripped off of crankshaft but did not make any punch holes though. @74k miles.
I thought I'd see this kind of stuff on your chanel but not in my garage :) but no...
