To elaborate on what the machine shop told me when they looked at my engine. A scored piston as previously mentioned will transfer heat and discolored the skirt which is like I said is not the case, its clean. Plus to add the cylinder is holding pressure. I hate doing this but per their advise. I will be installing the engine so that I could make a more elaborate synopsis of the engine noise. Instead of going by hear say, or simply by some other persons ears or interpretation. That and plus there aren't any parts for this thing except for the hi end speed shops which would break my wallet and might not offer any solution.
