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.
Hope you enjoy!

[@corvettejohn4507]

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.

[@derrickwoods2803]

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.

[@thomasmiddlebrooke1012]

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.

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.

[@madog1]

@@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.

There are some companies that won't credit a core return because of too much damage... This purchase - that the host who made this video probably was not a core, as most cores are sent to places that overhaul / rebuild the defective product. This was a purchase of something that was in unknown condition, but of potentially high value because of it's rarity and was probably made without the potential of a return, from the seller.... His video was of great value, which helped his ratings as a KZbin producer and participant...

Yep, lots of guys would buy/repair and run it.

[@ashcosmo3854]

@Eugene Foster I'd trust it enough over spending $15k for a new one but then again it depends how much a repair job would cost. If it's not that far off a new crate engine then I'd just go new.

@Eugene Foster I e had it done an ls1 years back and it lasted 100k and far as I know still being driven by the guy who bought it.

Love these straightforward videos so much. Absolutely well done!

[@darkechoproductionsllc9559]

Love your videos as just a tip, to get better actuate human voice sound. Take the lav mic and put it right in the middle of your chest. You get the best sound possible and use an eq sweep to clean up and good to go. Use a strip of medical tape place on chest, then take the lav and place another peace on the mic not covering the top end and place on the tape you put on your skin. Then make a triangle and place on lav and shirt and no russel sound. Good luck

18:00 That cylinder Hydrolocked... Too much water in the cylinder and the rod bent trying to compress it...

[@Broadpaw_Fox]

I disagree. That crack is too far down in the cylinder to be hydrolock. What it looks like is that someone was running that engine HARD - like boosted hard - and just had a knock situation develop. Enough pressure to twizzler the rod, but not enough to shatter anything (and if it was hydrolocked, that piston would have shattered). That's my $.02, anyway.

[@nathan.brazil780]

@@Broadpaw_Fox The crack is what caused the hydrolock not because of it... The cylinder cracked and the piston went down to draw in fuel / air and drew in a large amount of water instead (through the crack) then tried to compress it... Damage from forced induction normally causes the top piston ring and piston edge to blow out not crack a cylinder...

[@Broadpaw_Fox]

@@nathan.brazil780- I see where you're coming from, and I also understand the ring gap issue (splitting the piston crown because you ran out of gap). I guess it's how you look at it - I'm pretty sure that cracked cylinder (liner) was from hard use. Now whether that allowed a hydrolock situation or they just had catastrophic knock that cracked that cylinder and bent the rod at the same time is harder to say for sure. But that's what I'm seeing/feeling out of this. Basically, someone got greedy and ran out of luck/fuel/whatever.

@@garyfischer4357 - why not? Cam and lifters is a big job, strapping on boost is a less invasive job (heads can stay on). It seems you haven't heard about Sloppy mechanics here on youtube... he the face of 'easy boost. ;)

[@robinmurphy3085]

The blocks totally repairable! For racing your going to replace the sleeves anyway as well as milling the block. So a good tig weld, new sleeves and some machine work and your better than new! Then cut for fire rings and BAM! Racing engine!

As a self admitted mechanical novice, I've always found it much easier to take things apart than it is to put them back together. 🤨

[@jeffreywhitlatch1409]

Excellent tear down video. Very high video quality and excellent narration. Just makes me wonder how that rod got bent.

[@supercharged1303]

Great video. Everyone who understands what in engines knows that the LS7 is a bad block. Much too thin-walled. The best block is the 6.2L from Corvette

[@shadowopsairman1583]

Grab a 4.8,5.3, 6.0 iron block. Also bad Ring Gap, overboost can cause detonation next to hydrolock. If he knows the art of shot peening this engine can be restored.

Excellent common sense tear down of that LS7 wondering if anyone would fix the block weld it then re sleeve it. I didn’t look to see if those are Siamese liners. Great video thanks for sharing.

As an owner of an LS7, hoping this was a externally caused hydrolock (deep puddle drive through, etc.)

Me too,for all the "issues" you hear about,this isn't one I've heard of although you can get a cracked block on any engine.My ECU went out last year but being G.M. it was $140 (not including programming) for a brand new genuine item,imagine that on a Ferrari or a Porsche!!
