The BMW N54 Inline 6-cylinder twin-turbocharged engine featured in many of BMW’s production automobiles suffers from carbon build up on the intake valves as a result of direct injection. Positive crankcase pressure combined with a common crankcase ventilation system when used in conjunction with direct injection technology leaves intake valves defenseless from oil accumulation on the back of the valves and valve stems.

If you own a BMW with an N52, N52N, or N54 engine you can almost be assured that at some point you will be replacing the oil filter housing gasket seal. The seal in question is a soft rubber seal that sits in the filter housing and seals it to the engine block. Over time this seal due to exposure to heat and oil will become hard, shrink, and eventually lose its seal. What then results is a nice oil puddle underneath your vehicle originating from the oil filer housing.
