SEIZED LS7 7.0L C6 Corvette Z06 Core Engine Tear Down. What will I Find?

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.

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 🤔

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.

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.

A breakdown video...that actually ...dare i say..BREAKS DOWN...the BREAK DOWN...no corny music..well done algorithm..well done

Biggest surprise of them all was when his 10mm was exactly where he expected it to be.

You can't help but admire someone who knows what they heck they are doing. Very enjoyable to watch.

That milkshake brought all the blocks to the (junk) yard!

Been 50 years since I took an engine apart and this brought me back to my teenage years. Nicely done!

Your commentary has gotten much more ‘interesting’ in the last 2 years…‘adjustable rods’, ‘malice in the combustion palace’….’piston McNuggets’…great videos.

"Something very seriously un-right here" My new fav quote

That block would make a bad ass coffee table base.

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.

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.

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.

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!

You're attacking that LS7 the way Richard at Precision Transmission attacks a 4L80E trans!!

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.
