I think the bearing issue is way over-stated on this forum.

I totally agree, one or two guys hear a noise in their engines and all of a sudden we have a bearing issue. I think people are just gun shy after the bearing failures on the 2001 E46 M3's. As far as I am concerned there is no bearing issue with the S65 at all and it has proved itself as a pretty reliable engine.
