Just got my first Blackstone used oil analysis on my '01 boxster S. Everything came back great except for over double the universal 3.2L boxster average for copper. Blackstone suggests a possible bushing/bearing issue. I found a post Jake Raby made many years ago where he said that only the main and rod bearings have copper, and that copper is alloyed with manganese, of which the UOA found none. Any thoughts on what it could be? If nothing else, I'm probably just going to ignore it for now.
