So I am in process of building an Ls2 Rx7. I was able to pick up a 2006 GTO LS2+T56 with 28k. Today, I started taking the parts off to inspect, clean, and prep it for the install. Unfortunately I didn't get far since I ran into something not good.

The first thing I did was I pulled the plug and noticed that there's some oil in the #7 cyl(rear driver side). Then I realized that valve cover has a crack. So I pulled the valve cover and it was downhill from there. I will let the picture do the talking. Please let me know what you guys think.

This is what I noticed please confirm if you can
a) Multiple cracks on driver side valve cover - Does not seal up against the head from being so concaved
b) Unseated exhaust valve spring
c) Misalignment on roller & valve assembly
d) Large amount of debris under valve cover - both dirt/oil mixture and unknown broken pieces
e) Oil leaking into chamber thru valve stem seal which is why the spark plug is wet from oil

I never seen this type of issue before. So could someone please help me identify some scenario on what the hell happened, how bad is this, what is broken(head and piston contact?), and what should I do next? Anything helps at this point

Maybe the engine is out of a car that got rolled and it got smacked by either the brake booster or strut bar?

I would start by pulling the head off

That is wild. Hard to say with out pulling the head something got in between that piston and valve or maybe a casting flaw?? Keep us updated.

Something hit it and broke it during the wreck.

Pull the head and the valve and try to figure out if the head is salvageable. If that valve is bent above the valve seal, it may never come out without destroying the valve guide, which could be sleeved or replaced.

Either the valve is bent above the seal, or the rocker arm mount is bent.

edit - actually I'd pull the head and have it pressure tested before wasting alot of time on it. In hindsight it looks like both the valve and rocker arm mount are bent towards he intake port. Never seen that before, but I guess it's possible.

If it fails pressure test, time to buy a replacement 243.
