    Is this piston usable? Had a slight valve touchdown it appears..

    Was looking through my stash of motor parts, noticed this piston had a touchdown of some kind, wanted to know what the consensus was. To me I would think its just going to catch a valve where it has a "lip" now.

    Or will it be fine? Thoughts? Thanks!

    I think that it's going to depend if the ring grooves were hammered down and the rings don't move freely now. You may need to open that area with a small file... Ron

    Yea if the ring moves freely, I'd use it.

    Rings are fine, not a bit of damage anywhere else but on that valve relief. I wasnt sure If I could just grind/file that back down some, or If these pistons were coated in some way, and I wouldnt want to do that. Thanks guys, just wanted to check with "the gang" before I built an engine with that piston.

    Also, check that the wristpin hole has not been 'ovaled out' any. The impact looks light, but you want to make sure that the pin hole is not oblong.
