08 M3 Rod Bearing Replacement

Conekilla · 06-26-2017, 10:41 AM

My oil pan stripped out so I decided to have the rod bearings swapped out at the same time, for peace of mind. Attached are 2 pictures of the bearings and 1 of my latest oil analysis. Not really sure what "normal" wear looks like but my bearings look pretty good compared to others I've seen. The motor mounts however, were shot.

08 M3
41,800 miles
Replaced with BEBearings and rod bolts

Can you tell how many layers deep or if it is showing copper?

Not sure how many layers, but definitely no copper

No copper even along the sides or at the tops (parting lines)? If so, that is awesome and I wish we saw more like that.

I have an 08 with 42k miles. I've been very undecided myself on doing this. My last blackstone report showed low lead wear.
