Intake seat let go. Ended up resting at angle to valve (odd location, usually they sit flat if loose?) which ended up taking a chunk from top of piston and scuffing cam lobe from pressure created. Much work ahead of us this weekend :-(

How do the other cylinders look? It's possible that just one hole had a clogged injector or something that caused that pinging but it's unlikely. I think it's just the valve seat falling out and the resulting carnage that caused all that piston damage. Detonation erosion that I've seen usually shows up in the ring lands and sometimes gets so bad that you can see the top piston ring with the head off because the piston wore away.
What's the head look like? Is the exhaust valve burned? |
