There was no chunks. It was clean when I pulled it off. Weird. I think the chunk got shattered and exploded into a million pieces and went out the exhaust.

I knew a valve issue couldn't have been all there was, sucks to see this happen to you though. You've already had your share of problems from what I've gathered...

BTW- that head looks easily fixable. Just new valves, piston, rings and whatever else I can't see.

So what are you going to do from this point on? TTM fuel rail or sell?

I can't tell if that's actual damage to the sleeve. Benz_addict, can you confirm that the sleeve is damaged?

Regardless, if the option is between getting a new block and simply honing the sleeve, I'd hone the sleeve. Nikasil is nice and all, but it's not a deal breaker.

I have never seen the top of a piston break off like that before. I have blown a few ring lands off but not the top land. I have seen the top land burn off after ring failure but your ring still looks intact. Hope the cylinder wall is ok. If not sleeve it and go with custom pistons.

No way is that a fueling problem that looks like a purely mechanical failure to me,

Sorry to see this, I've just been through the same ordeal (only my piston damage was to the skirt).
I decided to rebuild the engine. We used forged pistons and modified the fuel rail. The car's been running great ever since and actually feels more responsive than before (possibly because the new pistons are lighter than the stockers).

Don't sweat it too much, its not as bad as it seems.
When it first happened I thought it was the end of the world. Looking back, it was just another hurdle.
