The OEM plastic PCV valve does not hold pressure well even when brand new. What this means is that when the turbochargers are making boost, pressurized air can become forced backwards through the valve and back into the crankcase. Depending on the condition of your PCV valve this can range from irritating to dangerous as a pressurized case can cause all sorts of issues. Additionally, if your valve cover is cracked due to age or has a bad gasket you are more than likely experiencing a pressure leak either internally or externally. These two features can cause even a low-mileage N54 to run like a tired elephant, sometimes even unlocking a special bonus function known as "Limp Mode". The solution is to replace any failed components and upgrade the PCV valve to something more capable withstanding the abuse of a turbocharged environment. FTP Motorsport has you covered with this solid aluminum valve assembly. It is essentially the same thing that came in your car from the factory, made out of aluminum. The internal components have also been made to fit tighter and outlast the life of an off the shelf replacement. No, this won't be the very last PCV valve you buy, but it will most certainly alleviate a lot of headaches common to N54 owners. And if you're tuned, big twin or single swapped you need one of these yesterday.
