Ok so I bought a set of used forged pistons which weren't in the greatest of shape but looked salvagable in my eyes, at least what I could see in the provided pics. Side note pics can be deceiving. Anyway one of the pistons shows signs of detonation to the point that it started to eat some chunks out of the top of it. My question is, which I think I may already know the answer but I would like some of your opinions is can the small crater in the top of the piston be welded back flush? If it can will there be any negative effects to the piston once it's welded, or should I just look into replacing this single piston. Thanks for your advise guys and gals.
