Well,i think BMW engineers that designed these motor are much better and more experienced to put out a motor that's having problems since some are saying that these motors are put together too tight.
and regarding the bearings in the 08 motors,they were never replaced in the following years or upgraded.All bearings are the same,from 2008-2012.I have one of the first production cars and when i broke down the motor,there were some wearing on the bearings but it was very acceptable coming out of a motor with 49k miles and being blown for 35k miles.
i will post some pics in my build thread soon !
