Do you have a clear look at the base gasket and are you sure the oil is coming from there and not something above the motor?

How old is the build?

It seems a low probability that if the motor was assembles correctly and there was no damage to the surfaces that there would later be an issue with the base gasket. (Did some of the 3.6 motors have this issue?)

Also, how much boost are you running?

Might check your blow by at the oil cap (BMW has a pressure tester I think but you might just look to see there is suction w the cap off) and do a leak down to see if you might have something going on that might pressurize the crank case?

It should be under vacuum because of the dry stump design I believe.
