Hey Guys,
I'm in the process of rebuilding my 1987 930 engine. Tear down has gone really well, with only one broken head stud. You can follow along here:

That said I have what seems to be strange bearing wear.
The front of the bearings look fantastic.
The back of the bearings however have some pretty significant wear, as seen here:
These appear to be the original bearings with date codes of 06-86, and the car has done about 95,000 miles. Is this normal wear or is it something I should be concerned about?
Thanks
Rich
