All of them seemed decent, and rebuildable. Not 1 of the 3 were good. Everyone I've sold bottom ends to are from another forum. They source their own pistons, S50's, M52's, etc

I like to do everything ONCE the RIGHT WAY.

I see

It seems to me for a guy who has recently done these engine tear downs you are/just have gone through the same stuff. So why are you so hard on this guy?
