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!
