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.

The OEM plastic Positive Crankcase Ventilation (PCV) valve does not hold pressure well, even when brand new. This means that when you are in boost conditions, the highly pressurized PCV valve leaks charged air back into the crankcase. Depending on the condition of your PCV valve, this can range from irritating to dangerous. Additionally, if your valve cover is cracked, loose, or has a bad gasket, you are likely experiencing a pressure leak either internally or externally, as well as potential oil loss issues. ECS Tuning now offers a solid aluminum PCV valve upgrade designed to address these issues by preventing leaks and outlasting the standard BMW-designed PCV! The internal components of this aluminum PCV valve fit tighter than the OE design and can withstand significantly more abuse, perfect for high mileage N54s, N54s that have been tuned, or N54s with upgraded turbos (larger twin or big single turbo builds). This may not be your last PCV Valve, but it will certainly outlast both the Genuine BMW and other common aftermarket alternatives!
