- 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!
-Eric - Auta a dopravní prostředky
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 to Jesus Christ
@@jesusislord6545 that is a good start - but don’t you need to make him your Lord and Savior?
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
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 to Jesus Christ!!!!
“7 spark plus with human set gaps, and 1 plug with an engine set gap” 😂😂
I love these disaster teardowns.
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.
Key phrase: "this thing sounds like a piggy bank." Great! Thanks for the great vid.
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!
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!
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.
"This engine is more window than door." I almost burst out laughing.
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”
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!
I watched a guy take apart motors for 4 hours on CZcams while taking apart a motor myself. Love my life.
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!
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!
A couple of statements that made me lol:
"Those must be quarters"
"A piston Mcnugget"
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.
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?
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.
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?
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.
One of the best tear downs you have done. The carnage is amazing.
Great video man !
I'm a certified powerplant mechanic and really appreciated your time and effort .. !
Thanks for sharing sir !
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.
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.
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"
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.
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
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.
Mate - that was awesome! Learn do much from you doing these tear downs! Nice job! 👍🏼😊
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!
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
'it's a pissed on mcnugget' Yep , I worry about that possibility at most restaurants.
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. 👍👍
Love these on Saturday nights!
great vids, your comments about what you think caused it and the probable sequence of events are my favorite part.
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.
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.
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.
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. 🤙👍😎
thanks for keeping us entertained
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 CZcams videos haha
GL this is a great video series to have. Probably help a lot of new engine builders as well
I like the effort you put in, and I can't really think of any other YT channel that you can also buy from.
Making my covid quarantine educational and entertaining..... thank you for your time making these videos
Hope you feel better soon!
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!
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.
Please never stop doing tear downs i seeing what happens to the motors more the merrier i enjoy the videos
This is pure bliss. So relaxing.
Thank you for taking the time to make these videos. I really look forward to Saturday night and watching a new tear down.
Do the v12 next! I don't think I've ever seen one of those torn down.
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?
Love watching this stuff man. Would love to see a TDI tear down in the future
love watching these engine autopsies and learning why they failed
It is totally about the entertainment. And I like watching what comes next so I like how you choose your next videos.
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!!!
Debri(s), I wonder how many people you piss off when you say the S. Awesome video.
I agree with Dan in that the windage tray is a major contender for your next "Broken Counter Piece"
When you're disassembling an engine for entertainment value, "Sometimes you win; sometimes you still win!" :-D
Great videos! You have the coolest job ever!
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!
I really like your channel. Very interesting for me. I just came here for your Exprit videos (a car I still adore - and I hope you will also do some additional content on). Also I love your comments, very entertaining! Like!
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 would be VERY interested in seeing you tear down the Toyota 5.7L! I'll be watching my notifications closely!
"Ah there's one, Oh crap I got my tool stuck"
Best word ever from a my working on an engine lol
Thanks Eric
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.
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.
Another Awesome Video Thanks Man 😀😊😊😊👍🏼
Great great channel...from Argentina with respect...
I loved that rod jamming itself between the cylinder and cam.
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
Wow that must have had to make one heck of a noise and lock up. Thank you for a great video. 🇨🇦
Awesome coffee table base!
I love that you mentioned Diesels 👍🇺🇲
That knock sensor got the knock of its life!
Knock sensor to connecting rod “ok ok ok stop taking my name literally”
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 💪.
Another awesome tear down! Total destruction. Cool stuff!
“that must be a quarter” you and your videos are awesome !! btw that was a LOT of Cs
The extra circular block ventilation and samurai sword action on the windage tray was an awesome sight to see.
ALL AMAZING! Can't believe the chain survived.
Always love your videos, of course! Only criticism I have is the camera quality, but I’ll admit I’m not an expert at all. Despite that, this is fantastic stuff. Until next time!
Piggybank!! Bwahaha!!! I love you’re show dude! Def therapy for me!!
I know nothing about cars and engines yet I look forward to these videos. I suppose there could be more people like me so we would be very interested in a video where you explain parts of the engine, how they works and what they do. Just an idea:)
My new favorite channel
Nice analysis.
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!
The tray will make a great piece for your display case
Great video
I love a bit if destruction
👍👍👍👍👍
Wow, Just WOW! I have see a lot of damaged engines. This one was unique.
Your quick little assessment at 22:51 was hilarious.
Nice same ls in my Cadillac Escalade. And I have a lly duramax. Can't Waite to watch the lly video
Open atmosphere cooling engine block very nice...
i totally am now addicted to your humor
I have this same truck here right now Great Videos
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
Absolute Mayhem sir!!
Another great video.
"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.
22:51 nicely done!
