These are really great discussions. A lot of knowledgeable people here. A few of us over on the M5 side have preventively changed our rod bearings out. I did mine at 50K and had sever cavitation on the top shell. All the top shells were just starting to get into the copper. Others have been in the 80k to 100k and were way worse than mine.
My BS report only showed 8 parts pb.

What I see so far is up to this point is:
1. I assume everyone used the BMW recommendation of 10W60 up to this point. We had no reason to do otherwise up to now.
2. 100% of the bearings that have been pulled, at least on the upper shell, were in bad shape. In fact we are starting to see spun bearings showing up on cars approaching 100k regularly.
3. No one has pulled a set out that has not been bad. I know there should be some wear but to me these are accelerated.

Over on the M5 board there is a guy in Germany that frequents our forum. He has been ringing the alarm bell on these S85 bearings as he changes them every week as a side business. He's got it down to a science.
