- If this is the first teardown you are finding, there are over 20 others I've done! Lots of LS's, A viper engine, rx8 rotary, and a couple SRT8 Hemi's to name a few. Check them out here • Blown Up Engine Tear D...
My name is Eric and I own and run a full service auto salvage business called Importapart located in the Saint Louis MO area. Part of our model is dismantling and selling parts from rare and niche market engines. If you're interested in buying parts from other engines I've torn down, email us at Importapartsales@gmail.com.
In this video I complete teardown a 6.2L GM L9H V8 which suffered from some pretty spectacular failures. A few firsts in this video for me! This is a flex fuel Gen4 6.2L V8 without DOD, with VVT found in 2009-13 Escalade and Denali, and the less common Tahoe LTZ.
I appreciate all of the comments, questions, and even the criticism!
Thanks for watching!

I know almost nothing about the internals of a car, but I can't stop watching these. No bs, no screaming, loud techno or that stuff, just a man who really, really knows what he is doing. Great videos, hell, I even managed to impress the old man the other day.
Engines arent too complicated especially LS's but these videos are a great way to learn if you have a basic understanding of pushrod engines
@@fiji3591 I have the slightest understanding of engines, but only the superficial stuff, like what the BIG parts are called, but seeing it all connected, and the walkthrough on those teardowns, have really learned me alot. Not even sure Im ever gonna use it for much, but that must be a testament to his videos, that Im still watching, and who know, hopefully I get to use something :)
@Kim - You can’t stop your brains thirst for learning…carry on!
Great way to learn about em for sure, helps me out a lot to learn about anything taking it apart and also shows you how something so complex like an engine isn’t as hard as it seems to figure out (or isn’t even as complex as it seems often)
Except for automatic transmissions, watching that taken apart has the opposite effect 😅
The sound of the carnage when this happened must have been impressive.
Light knock, I think she will still pull 😅 owner probably gave it more gas lol
I couldn't imagine how deafening it must have been when that rod broke free.
That oil change due light had only been flashing for maybe 25,000 miles
Did you see last weeks vid, the Mercedes diesel? That oil was like grease, just don’t understand some ppl.
The driver might have even heard the failure over the volume of their sound system.
“Good parts?” Who cares! Entertainment value! Gotta love it.
@Repent! that is a good start - but don’t you need to make him your Lord and Savior?
That windage tray is a contender for your next "Broken Counter Piece"
It’s a wall hanger!
It needs to be stuffed and mounted on the wall with an appropriate caption; such as “Redline, schmedline” or “Once we get over this hill, we’ll have no more trouble towing this loaded cement mixer to the garage.”
@@Mightion lol
This whole engine could be put on the counter 😂
@Repent! Get off the Jesus garbage. This isn't a Church.
Whenever I see this much pandemonium, I'm reminded of our '88 Ranger that started sputtering a couple miles from home. Dad knew this was The Time.
He put his foot to the floor, saying 'Oh no you don't, we're getting home one way or another'.
Much smoke and a short while later, it did, and we got home another way.
Keep up the great work, Eric!
Love ya work!! Especially the terms, like "engine set plug gap", "piston McNugget" and "aftermarket block inspection ports" Keep em coming please!!
Don’t forget “this engine sounds like a piggy bank”
“7 spark plus with human set gaps, and 1 plug with an engine set gap” 😂😂
I love these disaster teardowns.
I wonder if that knock sensor may have sensed something when this happened 🤣
It was the knock sensor that shut this engine down. That’s what they’re for isn’t it? haha
You know if I had one thing I didn't like about your channel it's that you don't post more. I can never get enough of your teardown videos!
At a mountain log cabin with .5 mb wifi throughput but still somehow managed to tune in to our boy. Another great Saturday night video!
17:02 More proof that this thing was still running full power after the rods failed. This is the sort of failure I would expect to see from an engine that's being intentionally killed for shits and giggles, or an engine that's in a police chase.
EXACTLY! The fact that a whole piston was reduced to chunks says it was run with full throttle for as long as it would still run. That failure would have instantly stopped an engine that was running at anything less than full-foot-to-the-floor-throttle. Somebody was really mad at that engine. LOL.
lol police chase.....when you try running from them and still managed to escape but with a blown engine...
@@White_Night_Demon You dont get away. They either let you go because they dont want you to kill an innocent and follow you with the helicopter/have officers waiting at your house, or they dogpile your arse until the fucking Dunkin catering crew is involved.
I'd guess stolen and then used for donuts.
The old-time Nitro racers would have an engine like that back together as a running V6 in time for the next round of racing.
Don't know why but this comment made me bust out laughing!
When I was 16 i was the teardown guy at a junk yard, loved it.
Did you put them back the exact same way is the question. Tearing down anything is easy lol (except rusty bolts) but engine compartments have no contaminant intrusion.
Key phrase: "this thing sounds like a piggy bank." Great! Thanks for the great vid.
I don't believe there is any give up in you, and I hold you in high esteem for it. I cannot think of a better way to spend a Saturday evening than watching you wrestle with a destroyed Chevrolet. Bravo Sir.
Eric, if I were you I would turn that entire shortblock into a corner display for your front office. The deck surfaces being 90 degrees apart will make it fit into a corner nicely. The way the broken rod simultaneously speared the cam tunnel, locking up the cam and breaking the cam bolt, almost perfectly sliced the windage tray in half, and nicely windowed both sides of the block makes me want to call it art. This would allow your customers to see the full destruction caused by the other broken parts on your counter.
Thanks for the awesome videos, as someone in a similar line of work with a similar passion for the inner workings of the internal combustion engine, I thoroughly enjoy them, keep up the great work.
I see most of your replies are very well versed in this industry so I could tell. I wish I could just cut a 6” sample cut of this engine where the rod is stuck and put it on my counter.
Thanks for watching and commenting!
It is a great idea. And maybe the art piece could be placed on a layer of some "engine gravel"? He would have plenty of it, if all of it is saved.
Too bad that you never know the mileage on any of these engines. It would be awesome to see how many miles any of these engines had on them when they exploded.
Mine had 60K
@@johnmclean2010 crazy. My work truck has 230k doesn’t even burn oil. I have however disabled DOD
The thing is, i’ve been a professional mechanic for 40 years and seen it all. Brand new failures, with 60 miles on them, the same brands engines going 475,000.
Haven’t found one brand that doesn’t break yet in all these years. Yet people have brands they love to hate and brands they love to love.
@@JimmyMakingitwork The active fuel management systems in these truck is destroying GM's reputation...
@@johnmclean2010
They have reputation?
Luc from Sweden here! You guy has such a nice and pleasant attitude in your performance and tone that makes, for me then, I find extremely instructive to see and listen to you in your movies! Thanks! Mvh Luc
"This engine is more window than door." I almost burst out laughing.
The engine carnage is fabulous. I love when you can figure out why the failure. Also makes you appreciate regular oil changes!
Don't think it was oil related since the bearings were OK, I own a GM and GM likes to program it's PCM to run as lean as possible, problem becomes that if there's any carbon buildup you get engine ping, I have to run mid-grade in mine to avoid it, throw in towing a load up a grade and BAM, piston lets go, like he said, these particular engines were known for it.
One of the best tear downs you have done. The carnage is amazing.
I don’t know if it’s the content or the commentary that makes these so satisfying to watch! Keep ‘em coming. The greater the catastrophe, the better.
Trick from Nicks Garage: take a plastic milk basket and cut out part of the sides so you can bridge over the leg of the stand and place a plastic container directly under the engine to catch fluids. Love your work.
Great video man !
I'm a certified powerplant mechanic and really appreciated your time and effort .. !
Thanks for sharing sir !
Hey buddy, another great video. That must have made some kind of noise when the connecting rod broke. Catastrophic damage. Another good engine bites the dust. Thanks for sharing. Big Al.
I'm a Honda guy. I respect the fact that most of the trucks I pass on the highway cost more in maintenance than my car costs. And that they try to drive fast. I do appreciate the attempt. I've owned some trucks, and they rock. My favorite engine was a 400 Ford I tore the side out of. But when I need a truck, I rent one, and drive it like I stole it.
That was stunning. That was an explosive disassembly I’ve never heard of being possible before let alone seen the aftermath of. Interesting analysis about the scenario being high load-low octane.
Why would low octane contribute to the piston overheating?
@@jberschi Low octane fuel would cause severe pinging and the knock sensor should adjust the timing to prevent engine carnage but maybe the owner put wrong fuel into tank...instead of premium unleaded vs regular. The piston melted or shattered under severe load from less desirable fuel. I am sure the noise it made prior to kaboom would have been heard. Seeing a conrod embedded in the block is crazy and timing gear bolt sheared is also totally nuts.
WOW ... the carnage on that head was knarly man! thanks for sharing. These are a lot like a train wreck ... you can't stop looking!
I watched a guy take apart motors for 4 hours on UA-cam while taking apart a motor myself. Love my life.
My 2015 6.2 L86 Silverado 117k miles just collapsed a lifter. Not catastrophic, I'm going to do a AFM delete myself. Great video for me to get familiar with this engine. I'm freaking out about doing this. I have built many old school engines , but this bad boy is on another level. Thanks for posting this video, very helpful. 👍👍
The engines that will get your channel amazing views are any LS’s, VQ’s, JZ motors, KA’s, RB’s, Cayotes and Hemis.
I’d put any of those you have as property, if you don’t believe me watch your view counts. Those engines always get massive interest in UA-cam videos haha
GL this is a great video series to have. Probably help a lot of new engine builders as well
Love engine autopsy videos, interesting no nonsense approach and entertaining commentary! Keep up the great work and hope more destroyed engines come your way, they sure make good videos!
11:59 That one threw a rod and the driver kept their foot in it 'cause it was still running on six. No doubt in my mind.
hey bud, i appreciate what you do for us sitting behinds the screen. its a good insight and i love how you dont go overboard explaining every little detail
You can’t let that little chunk of rod beat you! I expect a follow up where you pull out a die grinder and start removing block until you can get it loose!
I would have drilled it out.
Bigger hammer!
@@bsekisser I thought the air chisel was heading the right direction, but the chisel being used wasn't the right size/shape for that job. A torch would also have been fun! It's only aluminum, so it wouldn't have taken too much to soften it enough to punch the rod chunk out.
Better than Netflix on a Saturday night! Yes, I have no life.
I just returned from a fishing trip yesterday and in my old age, I just tow my travel trailer right at the speed limit (55mph). Going up a long uphill grade, I was barely doing 50 mph when a Toyota Tacoma went blasting by me towing a comparable size travel trailer. A few miles further, and that Tacoma was on the side of the freeway. I guess slow has benefits.
A couple of statements that made me lol:
"Those must be quarters"
"A piston Mcnugget"
That's what we call a "ventilated block." Wow... through both sides, nice. Sweet looking touring you got there. Looks good on those CSL style kicks. 🤙👍😎
22:50 The crank has contact craters covering the counter balance coming from the connecting rod's catastrophic collapse. Or in short... "There's your problem lady"
Love these on Saturday nights!
Do the v12 next! I don't think I've ever seen one of those torn down.
Please never stop doing tear downs i seeing what happens to the motors more the merrier i enjoy the videos
Breakdown the 7.3 next pls
^this
My only question is how did a 7.3 end up as a core?
Yes sir 7.3
I second that
Regardless of next engine I'll be watching. Still voting 7.3L . 99-03 or 94-97?
The comedy in this was awesome. I love Eric's sarcasm and his insights. Totally awesome video. The sheer destruction of this is insane! HOW...IN..THE...HELL...DID...THIS..HAPPEN? I'm glad you can discern what took place.
I agree with Dan in that the windage tray is a major contender for your next "Broken Counter Piece"
'it's a pissed on mcnugget' Yep , I worry about that possibility at most restaurants.
You called it right! Pre Detonation caused by low quality or low Octane fuel, usage non Dexos 2 approved oils. Which have a lower Calcium additive package to prevent Pre Detonation on piston crown edges.
I'm running an escalade (07), already changed the engine out because my older one had a bent crank shaft..... I wonder what else was wrong with it before that happened.... it had an oil sensor failure that put the vehicle in limp mode right away... had to tow it to the local cadillac stealer to do the remove and replace.
I absolutely love your video, thanks for this.
That windage tray has to go up on the wall. This was a great tear down. Watched almost all your engine breakdown videos and this is one of the most impressive. Keep them coming!
When you're disassembling an engine for entertainment value, "Sometimes you win; sometimes you still win!" :-D
Halfway through the video so far and you've had me laughing more than the last week. As for the piston mcnugget it has no sauce because it window-blocked. You *can* substitute the coolant you poured off but it's not the same.
piston mcnugget was funny as hell!
Making my covid quarantine educational and entertaining..... thank you for your time making these videos
Hope you feel better soon!
great vids, your comments about what you think caused it and the probable sequence of events are my favorite part.
I like the effort you put in, and I can't really think of any other YT channel that you can also buy from.
I think you got it right - high load / low octane. I imagine the scenario was the pop, then they weren't making progress on the hill, pulled over to see why there was smoke coming form the engine bay thinking they just overheated it, and then they were calling for a tow ruck because the engine wouldn't start. I can't imagine it running for any longer than a couple minutes after the piston went.
Debri(s), I wonder how many people you piss off when you say the S. Awesome video.
I would be VERY interested in seeing you tear down the Toyota 5.7L! I'll be watching my notifications closely!
Great video, I love watching you tear down engines, explaining what you find along the way. A few people actually get to do what they love and love doing it, you sir are one of them. I am lucky enough to be a subscriber to your increasing content and look forward to anything you upload. Keep up the fantastic work. Please tell me, is the tool box called Old Blue by you and your guys?
Excited to see the 3UR teardown. I'm a Toyota tech in the faraway land of Columbia Mo and the number of people I have heard saying the 5.7 design was stolen from the SBC is incredible.
love watching these engine autopsies and learning why they failed
Love your teardown vids, especially the ls destruction.
That intake manifold that you plan on selling definitely has metal in it and you can't get that all out.
I’ll get it all out. We’ve done it before
Great job. Good analysis too. I bought the l9h because I do not like dod/afm, but I always run premium and fuel and dont tow because of the fractured piston deal. Like you said, alot of the 6.2's break pistons. Great video.
Okay first things first, please! Tear down the 7.3 I can't wait to see what you find. As for this engine, if you made a dime on this engine congratulations you deserve it and then some... Loving your never say die attitude. By the way you should write for Hollywood some of the stuff you come up with is better than anything they have. Keep up the good work brother!
"It actually turns over good....... Until it doesn't actually." Not sure why but I laughed at that a bit more than I think I should have.
Sweet! I was waiting for this one! Have a L9H in my ‘12 GMC SIERRA SLT EX CAB w/ 134k still going strong!
( *5 MILES LATER* ):
Keep changing your oil on time and you'll be fine
Got an 2011 Silverado L9H powered. 295k miles. Still going strong 💪.
The 821 LS3 heads have hollow intake valves. 823 heads always have solid valves. No casting differences between them, aside from the part # of course.
Actually only 0821 from ls3’s have the lighter valves. I’ve seen several pairs of 821’s on SUV’s and truck engines that I bet don’t
@@I_Do_Cars That's what I said, but I had no idea that other LS engines could come with the 821's, so it's great to learn that. Thanks for the comment! Love your videos btw! Keep up the great work.
Those heads still bring in some good money as core heads. I wish i could get cores as cheap as u do. Ive had ls heads that look like that. I usually take a dremel and clean it up. Replace valve seats, guides, mill and as long as no cracks are found after the dremel phase.. cuz thats required in order to clean it up and see the magna Flux... then its good. Its amazing how much abuse a head can take and still be repaired. These ls engines are stout. I know a guy who can repair these cast blocks reliably after filling with cement for drag engines and sleeving them. So you can even sell these blocks still and make money. Cam journals can be repaired
That knock sensor got the knock of its life!
Knock sensor to connecting rod “ok ok ok stop taking my name literally”
Mate - that was awesome! Learn do much from you doing these tear downs! Nice job! 👍🏼😊
Win win!!! I want that stuck rod chunk!!! That’s a keeper!!! Keep tearin em down!!!
i think if he would get it out that would be a great desk piece!!!
I would love to know how long the engine continued to spin after the initial piston disinegrated to create all the small parts and gravel ? The nearly torn in half windage tray was the greatest along with the "peyronie's disease" push rods.
thanks for keeping us entertained
Open atmosphere cooling engine block very nice...
Thank you for taking the time to make these videos. I really look forward to Saturday night and watching a new tear down.
Is anyone else laughing maniacally watching (and listening to) this teardown? Or is it just me?
yup I'm laughing like a madman. I'm in a bar watching and I'm getting some confused looks
real excited about the 2uz 4.7L and 3ur-fe 5.7L Toyota engine teardowns!!! Can't wait to see whats wrong with a Toyota million mile engine!
I love seeing these blown up engines! Even if they arn't, it's great to see the tech used to make these engins.
What do you do with all the screws, nuts and bolts you pull from these engins?
When I go to a salvage hard I love to pick up loose bolts and stuff as well as pulling good fuses and such for my spares kit. The bolts nuts and all are great for project building and stuff.
Thanks for putting these videos up!
I save about 50% of the hardware, usually just off Japanese and domestic engines. I do save some of the euro stuff too, just depends on what it is
"Ah there's one, Oh crap I got my tool stuck"
Best word ever from a my working on an engine lol
Thanks Eric
The extra circular block ventilation and samurai sword action on the windage tray was an awesome sight to see.
Sometimes I wonder wtf people do to these engines to make em blow up this bad 😂
I loved that rod jamming itself between the cylinder and cam.
i totally am now addicted to your humor
good videos no loud rock music just words explaining things you could teach auto shop
I love the diagnosis and theorizing on the failure mode. really fun stuff Eric! is that windage tray going in your collection of masterpieces?
It absolutely is!
It is totally about the entertainment. And I like watching what comes next so I like how you choose your next videos.
You mentioned in other videos that you have bolt boxes for different brands. I would buy a box that had entire bolt set for an ls engine. If its something you could sell reasonably.
I would absolutely. But, what’s a good quantity?
@@I_Do_Cars one about the size of a large fist! Any assortment of useable metric sizes is what I'd purchase!😃
Seriously!
I was thinking one engine. So like average dude in his garage loosing or messing up a bolt can still finish and not have to go hunt for a replacement. Personally I want a spare set on my airboat so if crap vibrates out and is lost I can fix whatever and get home.
But I dont know if its worthwhile to sell and hassle with. I would think $20-30 range..
I’ll figure something out. I’ve had a lot of requests for things like that but every engine is dressed differently so the quantity and selection of bolts would vary wildly.
It's amazing the amount of negligence and misuse
ALL AMAZING! Can't believe the chain survived.
This is pure bliss. So relaxing.
Your quick little assessment at 22:51 was hilarious.
The driver of that vehicle must have thought the Apocalypse had arrived when that thing let go. That tear through the windage tray is unreal!
Yes!!!!!! The ones we love. Carnage Supreme! Here we go with another episode of CSI:Engine Lab. Eric standing with his sunglasses in his hand 'it's a GM guys...and that doesn't stand for Great Motors. Today...it's General Mayhem'' Sunglasses on and theme music. Except no theme music exists for this channel.
Love watching this stuff man. Would love to see a TDI tear down in the future
Piston said "no", crank said "the hell you are" and the rod was like "bye!"
But seriously, that rod must've been goin Mach jesus to do all that!
Awesome coffee table base!
Nice same ls in my Cadillac Escalade. And I have a lly duramax. Can't Waite to watch the lly video
Wow, Just WOW! I have see a lot of damaged engines. This one was unique.
Zipping the main bolts out it sounds like Space Invaders
I am picturing an Aquarium with 'Piston Gravel' in the bottom, a pickup tube for the filter system, and some stacked pistons to make an artificial reef.
Always amazing to me to see you pull fist sized chunks of metal out from around the crank where they shouldn't be, and there isn't (normally) room for anything that large.
I have to remind myself when I see something like this, that while it's entertaining for me, it completely ruined someone's day.
Put that Block on display until you find one with even more carnage....I love this stuff.
