I’m not an engine genius, but I would guess that’s my supposed to be like that. All the other pistons are straight. The only reason I didn’t just say it was bad is because that’s a pretty thick piece of metal, and in my mind shouldn’t bend like that and maybe it came from the factory like that. We suspect that this piston had a spin bearing. It came from an engine that I bought from a friend I’ve never seen it run and the oil was long over due for a change. It’s in cylinder 6 all the way in the back if that makes a difference. What I do know about the engine is it blew a head gasket after overheating. That’s all I know about it

it’s all good. I’ve got two engines to pull parts from to make one good engine. Just curious if it’s supposed to be like that
