The crankcase oil vent system on the N52/N54 is one of its weakest and cheaply designed systems. We see crankcase vent issues on even stock engines but with more boost the problems are exponential. This Vargas upgraded PCV valve, and an oil catch can, are what the N54 engine needs and may alleviate most of your oil and boost leak issues. The PCV valve is supposed to let oil either return to the oil pan or pass through the intake manifold and get burned up in the combustion chamber. However, BMW used a weak plastic vent valve that doesn't seal well when under boost. Instead of closing and venting the oil out of the intake, it's forced through this valve and into the intake and coating your valves with oil residue and carbon. Most boost equals more oil forcing its way by. This upgraded N54 PCV valve uses higher grade materials, including aluminum, to provide a better seal and prevent oil from entering the intake. It's an easy install and a must-have item when considering any turbo work.
