I recently tore into my 440 because I found some scaring on the exaust side of on piston. When I took the pins out, I noticed that both ends of both pins were blue-ish/purple. I haven't noticed this on others, but that is not to say that it doesn't happen. Can anyone confirm if this is normal?
Also the top(I think) ring of both slugs had some odd marks on them. Sort of like pitting, only on one side. It deffinately has texture to it. Almost like electrolosis? What in the hell causes this?
