 Again, I apologize for jumping in here.
TIA!

No problem....I like learning about this stuff also. Bobs the oil guy has a good explanation of what all the ingredients represent under oil analysis, I would post the link but I've been having a hard time letting the site let me post and don't want to leave this page now, might not make it back.
The cams ride on aluminum journals so I don't think there would be any copper with the cams. I was in denial that it could be the crank bearings.....but it's about the only thing left, I think. Unless valve guides have any copper in them.
The lab stated the higher copper readings were "unusual" because nothing else was higher like tin, lead, if the crank bearings are the problem. But they said the copper wasn't too high to be a problem yet and said overall everything looked good.
