HAS the short block been replaced on your car?? BMW used a different type of aluminum alloy on the 1993 thru 1995 M60's & ALL of them will erode the cylinder walls and create all kinds of problems!! Check engine codes for O2 problems show up FIRST!!
Also on that engine there is a plastic crankcase "breather" plate on the rear on the intake that causes simular problems.
