OP - What bearings do you have installed in your engine? Older 088/089 or the newer 702/703? I'm assuming new 702/703. The newer 702/703 bearings do not have copper/lead in them. I was on the phone with Blackstone Labs for a good amount of time trying to explain to them that many S85 owners who are changing their bearings are putting in the new 702/703 bearings and that lead count cannot be used to indicate bearing wear anymore for those running the newer bearings.
It took them awhile to grasp what I was saying as they kept stating that e6x M5/M6s have the copper/lead based bearings, and yes, this is true during the production of those cars, but for anyone who is changing out their bearings after 2011 the 088/089 copper/lead based bearings are no longer available and only the aluminum based 702/703 bearings are available now.
I think it's best if you let BS Labs know in your next report that you aren't using the older 088/089 bearings anymore and are using the 702/703. They do know that from 2011+ the S65 M3s are using the 702/703 bearings, but they do not know that many of us are now putting in the 702/703 bearings into our cars.
