Fuel: 91 Oct
Driving Habits: Mostly highway/street driving, no track use
Oil Analysis: None provided
Notes:
This particular M3 was fully serviced under scheduled maintenance and meticulously followed thereafter with oil changes every 7500mi.
Here's a recent inspection on a 2008 M3 with ~53K that came in. When engine was warm, a "knock" was heard at 3500+ RPM. Upon inspection of #5 journal, the bearings were discovered to be in terrible condition:
Crank also shows severe damage, engine will need to be pulled and crank/bearings replaced. With this much damage on the journal, there's really no need to inspect the others. Higher resolution photos can be found here on our Flickr page.
Engine is relatively stock other than aftermarket exhaust, vehicle has never been tracked. An oil sample has been sent simply to see what numbers are present in this type of situation.
We'll update the thread as soon as the results are received.

will he be opting for coated bearings or just OEM bearings?
