It is weird how in all these oil analyses, we see bearings showing a lot of copper, and it doesn't show up in their report. Could it be the copper doesn't wear from the bearing the same way the lead wears away? It seems like there would at least be a little rise in copper, but it doesn't happen.
Agree, your bearings look good in comparison to others. I'll be doing mine very soon. I've been honing my mechanical abilities on my son's 330Ci.

Good question. Wondering the same thing too.
