But I am also gonna get a brand new short block and install it. I understand the 2009 engines are much better in terms of main bearings and linings.
I think the 08 M3 engines dont seem to be as well made as the 2009 ones. The 2008 ones have Main Bearing issues as well which SnowsM3 and Knifegun's car had. Of course not all, but its still a cause of concern.
Yikes an M3 not to be driven hard. What else!!!!
