Bearing Wear Question

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: http://forums.pelicanparts.com/911-930-turbo-super-charging-forum/902779-engine-rebuild-rich76-style-2.html

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
