A big part of my business is parting out core engines. Well we got something REALLY exciting in. An LS7! The only problem, its locked up. I rarely get a story with engines as to why they are bad. So I decided to make a video of the tear down in real time so you can see what happened, and what parts are salvageable.
If I get some positive feedback on this video I'll do more as we get ~200 core LS architecture engines in a year, as well a 6.1L Hemi, Cummins, mazdaspeed3 and 6, etc.
If you are in the market for Gen3 or Gen4 LS engine parts, we usually have lots of 5.3, 6.0 and 6.2 builder short blocks, 243/799 and 821/823/5364 heads available! Feel free to call us at 314-502-3104 during normal business hours.

Dude, Just stumbled on this vid. A+. why? No annoying music, No shilling crap, this is a simple to the point video, the way it should be done.
HUGE ditto for the absence of "music." Why is it so hard for creators to understand that the music you like may not be the music I like?
@@yanwo2359 A great video like this doesn't need music. I think the music is just to gloss over videos that are no good. Usually have to mute the annoying music (shouldn't even call it music) just to watch those videos, or better just don't watch them and have to close them quickly.
@@yanwo2359 im the one when I hear music on a video, or shilling some scam game or vpn is it an automatic dislike from me.
@@Dratchev241 it helps those people make money. You understand what a sponsor is, I hope.
@@Creesic If they need to shill scams for money maybe they need to just get a real job.
I don't know why but watching you tear down a motor to discover the cause of someone else's misfortune is highly relaxing for some reason 🤔
It's relaxing because somebody else is doing the work and you don't have to get it sorted for Monday morning to get to work
ommmmmmmmmmmmmmmmmmmmmm I agree
Its because it ain't our money that just went down the tubes.
I agree I love watching these
It's good because it's not your motor LOL
This is so much better than a lot of the crap out there on YT. No excessive/unnecessary cuts, no long, self-aggrandizing intro, no music over the top of everything. Great job- very enjoyable to watch.
FWIW, here's my take on what happened:
Since I didn't see any anti-freeze color in the milk shake, I'm going to assume the owner was running straight water in it for whatever reason. Winter came, it sat outside and got below freezing, and the water froze. When the water in the water jacket froze, it cracked the block and the sleeve. When it does this, it usually pushes in on the bore making it more oval shaped instead of round. Water ran in through the crack and filled the cylinder. Owner started car and hydro-locked that cylinder which caused the bent rod and the locked up condition.
Why would someone run straight water though I could see this in some old clapped out Honda but not a Corvette most of those people are anal about everything including the leather Vette coats all of them wear lol but anything possible I guess
Classic Hydro-lock
Old guy must have owned it, “water” is usually the only thing they say when it comes to “coolant” issues lol they never use the word coolant for some reason
...possibly-(!)
Who's running water in a Z06 for coolant? Hard one to buy/sell, but some people don't deserve shiny things! Mine runs quality glycol!!!!
A breakdown video...that actually ...dare i say..BREAKS DOWN...the BREAK DOWN...no corny music..well done algorithm..well done
Yes man!
Dude for real!
Boomer moment

Yeah his videos are legit
That milkshake brought all the blocks to the (junk) yard!
Damnit i was going to post this
There car is better than yours...there vette is better than yours
He can teach you, but he'll have to charge.
What causes that milkshake????
@@markbraid4433 coolant and oil mixing
Biggest surprise of them all was when his 10mm was exactly where he expected it to be.
Amen, the video was believable up until that point
Exactly, Mine would have been in another parallel universe.
All 10 mm wrenches turn up near the battery terminals in random customer's cars.
Isn't that why mechanics buy them by the box? :-D
Always the 10mm
Your commentary has gotten much more ‘interesting’ in the last 2 years…‘adjustable rods’, ‘malice in the combustion palace’….’piston McNuggets’…great videos.
Really enjoyed your vid. No fluff, no awful music, good camera, lighting, and audio work. Getting to spend some virtual time in the shop. Cool. Subbed.
Thanks, that's quite a genuine compliment. I'm not one for all the unnecessary stuff.
Agreed. Been a long, long time since I did any engine deconstruction. Back before I realized that having the right tools makes all the difference. Thanks for the tour.
Neil Reid: Ditto! Subbed also!
"Something very seriously un-right here"
My new fav quote
You can't help but admire someone who knows what they heck they are doing. Very enjoyable to watch.
Some of my best hands on education from senior mechanics in life was tearing down something considered not repairable.
Usually the shop boss would put it on a workbench near the end of shift and the apprentices would tear it down a little at a time each day. The shop boss & journeyman would unlock the beer keg cooler and drink a beer together discussing days events when we disassembled something.
Like the cracked block in the video, sometimes shop boss would buy parts for a trial repair if we had a use for it.
Great video, no music , liked the fast forward through repetition.
Been 50 years since I took an engine apart and this brought me back to my teenage years. Nicely done!
Back in the day did a 375 HP 396, couple 350's, a Lycoming io-360...and a bunch of Harley's. Would love to tinker with an LS lol
That block would make a bad ass coffee table base.
What a beautiful engine, all that clean aluminum! I drove a Z06 fro three years; what a fine machine. A shame this one was ruined.
User name check out.
Great Channel for all of us old guys to watch a young guy work and playing with engines....
You're attacking that LS7 the way Richard at Precision Transmission attacks a 4L80E trans!!
No... This guy isn't bought by Milwaukee.
@@king0cans he is using a Milwaukee driver, and Rich only just recently started using Milwaukee tools.
@@king0cans Wait what's your point?
@Diego Adame The owner used cheap oil and filters. Probably didn't ever change it either.
@@king0cans So you're saying Richard and Trent have been influenced, in a negative way, by gaining a sponsorship? I've been watching their content for over 2 1/2 years now. A few Milwaukee cordless tools has not impacted their integrity. TH-cam is a business. I wish PT's channel had MORE sponsors.... or in your terms, more companies "buying them out". 😐
Casey Jones sez: "The block's got a crack in it the size of the San Andreas."
Is that the same Casey Jones that said "Just one more bump before a take my shift at the train yard"?
I get to see all these engines and disassembly procedures that I would never get to on my own. From one motorhead to another, I love it all and thank you brother man!
The ls7s are hand assembled by one person at the GM Assembly factory those marks are from the factory
@_Schwalbe_262_ insane, like 25k crate... They're bad ass though!
@@jesterokjones4954 I believe that price is with the ecu and harness. Correct me if I'm wrong. Really isn't a bad price when you consider what you are getting and if you had to build it yourself.
@@scottgas1299 yeah, an aluminum 427 block by itself is nearing 10k...
@@jesterokjones4954 yep, try to build and tune it for the same money, not gonna happen. Then consider that the LS7 is epa friendly, if that matters to you
@@aw11man26 not here it doesn't matter, these stupid fuckers will have ICE's outlawed in a decade or so anyhow, so build'em to run rich and nasty! Big white spark while dumping as much fuel and air as you can with most advanced timing at the highest compression with forced induction and LET'ER EAT because it'll all be gone soon, another relic ...the very thought makes me want to puke and cry all at once....
Don't know anything about engines but watching the teardown and diagnosis was really interesting
I've never torn down an engine, never been that far inside one, never even seen how a non-overhead cam engine is arranged! But I was impressed I spotted all the problems along the way just as you did.
The greatest Chevrolet V-8 ever made and they do this to it. All LS7 engines deserve to be restored and end up in something cool. They are museum pieces regardless of condition. Hell, I'd take one with a hole in the block and turn it into a coffee table.
Looks like cylinder 7 hydrolocked the piston bending the rod. The crack in the block was likely from an overheat, due to a steam bubble that forms when the coolant is low, which I assume that would be the first thing topped off when the driver sees the temp gauge. If a hot car sits off with the crack in the block enough water will leak into the cylinder so that when the driver goes to start it back up for the next run, cylinder 7 gets the adjustable rod mod. The head may have survived only because the gasket tends to fail first(Ask Cleetus McFarland) which may also explain why the head gaskets were not put back on the previous teardown.
2 minutes in and I subscribed. All meat and potatoes, no julienned squash with slivered almonds..
I like that way of putting it
I’m stealing that phrase
Same here it was a recommendation since I do a lot of motorcycle and automotive repairs love the absence of background 🎶 just straight chat and knowledge 👍
I have a Corvette Z06 with this engine. I loved watching this video and I know these are hand built and those markings are from the factory. Beautiful engine.
Great video, No *Rap Crap Music* No *Clickbait* , Good Camera and good Lighting .this is how all TH-cam videos be,straight to the point!
No stupid jokes or singing eithet
Or stupid rock n roll music
I love this guy. He's like the Quincy of engines. These tears ol autopsies are great
Great video. Appreciate the LACK of music. Thank you for sharing
Cracked block.
"It's dead, Jim".
A dab of epoxy cement and six cans of rad-weld will fix 'er right up! Trust me! ;-)
Throw a new sleeve in it, tack weld/JBweld the crack, and call it "rebuilt"!
Pass the savings onto your customers!!!
...all sarcasm by the way, this is why you dont trust any random person selling a rebuilt engine
Mike Harris Aaah, I see you know how to do a Craigslist rebuild too.Haha.
I do believe you single handedly created an amazing and new video genre with doing this. I love it so much!
Great work with your videos ,they really help us understand the problems we my come face to face with in our daily projects.
It's fun to imagine the last guy who put this back together watching
What do you do with all the cores? Recondition? Part out? Cool business!
Kudos repeating previous posts. I don’t watch a lot of auto mechanic video, but you brought me back. Stick with this format. Liked and subscribed.
Great video, no junk, nothing to waste my time, just a fun tear down of a seized up motor, I'd definately watch more of these.
Great video, don’t worry if it was bad or not... great work and plenty of knowledge through your showcase.. keep posting and we all know you’re a great mechanic
Love see more teardowns like. Thanks for doing this.
"Did you pull out?"
"Yes."

Super video. I am learning a great deal from your efforts to break down these engines.
Really enjoying these videos. Great work. Bonus points for no cheesy music!
Thanks for sharing.
Breaks my heart to see an LS down for the count. I love those engines. Running an LS1 in my Trans Am, making lots of power. 23 years old and strong as the day it was built. I take major good care of it. Big Al.
youve been driving that ls1 for 23 years? 🤣
@@thephantomzoneboxing yes sir, makes 800 h.p. For the last 20 years.
@@allenbeaulieu7077 how many miles on it? how many rebuilds?
@@thephantomzoneboxing 29000, 0 rebuilds
@@allenbeaulieu7077 290,000 thousand you mean?..29,000 in 23 years what you just drive it around the block and back 🤣
Can’t believe how clean the inside of that engine was.
No idea why I watched this whole video, but it was cool to see your discovery with no fluff. Nice work
This was the most Zen video I've ever watched. So relaxing just watching you pull that motor apart. Awesome.
You're right, especially when someone else helped loosen the bolts. It wouldn't be so Zen if I busted my knuckles which I'm very inclined to do.
That is a nice block being a LS7. Could you save it by TIG welding the crack shut then redress the block bore to accept a new sleeve? That block is too valuable to call junk.
sleeves would be the answer and a few new parts.
:) back in the day, I pulled my 455 to fix the rear main seal leak. Rope seals. I pulled the sheetmetal off the front end, cleaned and painted everything, pulled the engine, turned it upside down on the stand yanked the pan...and saw two broken pistons. The damn thing was running like a champ too, I was just sick of the oil stains. You never know what you might find lol.
Pontiacs have all the durability of a potato chip. 😀
@@drippinglass lol how would you know? You can't even guess whose engine it was so what means you know jack about shit?
@@bbb462cid well which 455 was it?
@@juliennacer8871 Buick. '74 block with the enlarged oil passages. The cylinders were scratched from the pistons so I had it bored .030 over, and then I put on TA Stage 1 heads, aluminum intake, split duration version of a Stage 1 cam, 10:1 forged pistons, roller rockers, adjusable oil pump with thrust plate, 7/8" primary tube headers to a 3" collector and 2 inch pipes.
@@bbb462cid sounds badass. which intake did you opt for?
Love these straightforward videos so much. Absolutely well done!
Excellent. You are not an arrogant person like so many other people are.
How does this man only have 21k subscribers? Dude's awesome!
Not many engine guys say disgusting over and over
He's got 270k now but still a little on the low side given some of the crazy subscription numbers out there.
It hydro locked when the block cracked.
You mean the block cracked when it hydolocked
@@redline9579 Beat me to it!
@@redline9579 well if the crack let in coolant then....
@@nyplantingsgardendesigners5645 nope. as u can see the oil is a milkshake witch means blow head gasket. water come into cylinder and hydrolock bent rod and crack the block.
Head gasket failed. Coolant leaked into cylinder causing hydrolock. Bang, crunch and another one bites the dust.
I was shopping for a Corvette 427 with the LS7 engine and this video was recommended to me. Thank you very much!
This kind of videos deserves more attention. No annoying music, just the point of the video, tearing appart an engine and find why failed.
I’m ready to see that viper engine come apart.
I must admit I said spun bearing at the start of your video, but after your autopsy of the bottom end, bent con rod caused by hydro lock seems more fitting to what happened to this poor engine. Great video!
Well, that’s the usual death of an LS motor.
I know nothing of cars/engines, but love these videos. Very informative, well done..
Very good video, actual breaking down an engine no music just listening to your diagnosis was comforting. New sub here
I like the speedin up of the vid, thanks for that, subscribed for sure. This kinda stuff interest me.
Nice job...I enjoyed this tear down.
as an owner of a c6 ZO6 I was impressed the the LS7 engine is a beast and in the ZO6 slamming gears is fun. nice that you get right to the point.
Change oil more often
This has got to be one of your earliest engine tear-downs, the genesis is there for what it will become by 2023. Great start to a fab channel!
i always see your ad updates on fb. we appreciate you
Great vid, an easy watch, ur a natural. Fun to see what happened to the engine, be interesting to find out why it happened, perhaps it was a first time for someone putting it together?
Absolutely the best engine strip down in trying to diagnose a fault. .
Have been subbed for about a year and this popped up in suggestions. Nice to see how you have grown your presentation and shtick since this video.
Really good breakdown of engine. I would love to get into this. My projects are normally a lot simpler
Man! Those motors are straight up and to the point.
No wonder they're so popular.
Great video man.
I’m building a destroked 6.0 right now. An easy 1400hp and 1000ft/lbs.
No overhead cams, hence the pushrods
This is oddly satisfying. Kind of reminds me of troubleshooting mechanical issues on my RC cars. You never know what might cause the strange noise you are hearing until you tear that thing apart and find all kind of surprises...
You have come a long way Eric.
Great videos
Love the to the point video format.
Very professional. Professional as in to the point, no crap music, nothing to distract viewer. Like we are virtually with him doing the break-down without getting our hands dirty..

I remember watching this when you first uploaded!
Outstanding job!
It has been a long time since i tore an engine down. Was curious to see the differences in newer motors. Awesome vid thx.
Definitely a hydra lock , block is repairable and well worth it .
Not worth it to fix a block that has a crack in it. Maybe if it was just the sleeve but it cracked the water jacket too
Yes and no. Hydro lock but too risky to repair. 7L have thin walls to begin with.
@@kyleyoung5754 clean that crack up and fill it with jb weld and run it.
Correct. Wet sleeve it and send it.
Is the block a wet sleeve design?
Cool teardown! Glad this video is doing so well for your channel. Must be really exciting. :D
That engine is SO clean inside and out I'm guessing someone already did a stock rebuild.
My thought is maybe they missed the crack thinking it was a head gasket issue instead?
Put it back together, ran it, ingested coolant, locked right up. Just a theory maybe way off.
Stock bottom end LS7, factory LS7 cam, cracked sleeve & block, bent rod…. My guess is that it had a bolt on supercharger. GM has plainly stated that the LS7 block is designed for no more than 550HP. I’d never risk a $12k motor with a slap on supercharger without totally building the bottom end to handle it. New Darton sleeves and all.
At 07:00 you were seriously contemplating if it's worth it anymore...but you pulled through and found some more. I would love to just video tearing engines apart like you. 👍 you are indeed on of the most experienced mechanics for sure
Although I really enjoy watching the destruction I would like to see this guy score a win once in a while. Seems like a lot of bad ones coming through.
Well I expect people to sell their junk, who sells a good motor?
This _was_ a win. He got two good heads, a good crank and seven rods and pistons, probably the cam was all right too.
It'll make a good coffee table
Or engine. Really easy to fix.
Nice work. Good presentation with no hystrionics just calm delivery of relevant info.
👍🏿🇭🇲👍🏿
Really appreciate the work you do. I also find the videos educational and relaxing.
Saw that rod slop/drop when you pulled the cap. Knew something serious was on the way.
Didn't know Adam Sandler worked on cars.
Almost,lol.
8 Crazy Cylinders?
Exactly what I thought.
I dont know anything about Engines. I get into my Car every morning to go to work- How it works is a mystery- this video was very interesting.
I dare say that this video is more entertaining than anything sandler has ever done on his best day(except punch drunk).
@@pgtmr2713 Nice one.
I really can’t say thank you enough for all of this.
Love watching you taking them apart
It's cool seeing people that you knew growing up having a good interesting channel.
"You've got a bent rod. - I do cars
"Yeah, but what's wrong with my engine?" - Me
"Aww, nothing really. You can drive it home. Here's the keys."
All I can say is Superman working on breaking down engines. Awesome.
Just found your channel with the viper tear down. Really enjoy the engine tear downs, had to subscribe. Thank you for sharing
Haven't torn down a small block (do we consider a 7 L 'small'?) For 15 yrs or so but holy cow they sure have progressed.
After seeing the teardown, looks like hydro-locked. Was that the cylinder that cracked with bent rod?
i believe so
Yes. At 6:57 he shows the crack in #7 cylinder wall, and at 17:58 he shows piston and rod #7 as the bent one. Good eye!
Exactly my thoughts. They blew a head gasket, kept driving it until that cylinder filled up with more water than it could compress then boom. Cracked cylinder and bent rod. Question is how long did it continue to turn over with a bent rod in order to scorch those rod caps like that?? I'd say that block could be re-jugged and fixed.
@@adamcrux6829 it could NOT compress any of the water, liquids don’t compress. Air or any other “gas” is compressible. 😉 Therefore the liquid had nowhere to expand, so it bent the rod and broke the weakest link, in this case the cylinder.
@@adamcrux6829 just to be clear, “gas” or “gases” NOT gasoline 😁
I know little to nothing at all about engines but I have spent a few hours at this point watching your videos.
I found this video and thought it would be interesting because I have heard about that specific engine was seizing up with such low milage on it. Well now I have seen and heard what you have said about it. This has been very interesting and I did learn a lot from it. So this is the first video from you that I have ever watched and I really think you did a fantastic job at presenting it. It's too bad that the engine had already been torn down previously which is probably why it was for sale. So you are correct about just selling parts from it. Great work!
As soon as I started watching I said it’s the number 7 piston. They’re famous for that. Especially if there’s been a power adder bolted on. Did it have have a blower installed on it?
Now that you mention it I always had trouble finding out that the #7 lobe on the cam was flat. Talking with others found out it was not so rare.
So what makes number 7 so special?
@@cantdestroyher7245 it’s not special Per se. but they were known for the rod in cylinder 7 grenading especially when guys started putting blowers in them with too much boost. Need forged internals when approaching 700 horsepower.
@@remnard1 sad thing is it has titanium rods from the factory. I think people see that and think they can boost it like crazy. only thing is those titanium rods I think were because it revs so high, for a stock 7 liter production engine. I don't think they were selected for ultimate strength. I remember seeing a new, at the time, C6 Z06 throw a rod on the dyno because of a 250 shot of spray.
@@scottgas1299 true but I don’t believe it’s a forged crank either.
Love the titanium rods they used on these. Fancy
But they rub each other...
@@corvetteZ3r the wrong way.
It was worth the wait to see that last pushrod. Looks like modern art.....awesome....!
I can’t stop watching your videos
I wouldn't part it. Well worth the machine work
this guy is like a demolition worker. He tears em all down. He not machining or building it seems.
Thats a really well put together motor that would be a dream to work on. With all the water oil milkshake mix could it have been a hydralic lock that caused the issues?
Love you videos, so informative….. keep up the GREAT WORK……..THANK YOU FOR DOING THESE…
A very nicely engineered engine. Thanks for the vid.
