BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate.

For your BMW's optimal performance, ensure the functionality of the hose connecting the oil dipstick to the crankcase vent valve. Positioned below the intake manifold, this hose is susceptible to clogging with oil film and condensation, leading to potential failure over time. Cracks and swelling in old hoses can result in oil and vacuum leaks, compromising engine performance.

Essential component for BMW engine functionality
Prevents clogging and potential hose failure
Minimizes oil and vacuum leaks
Convenient replacement when replacing crankcase vent valve

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!

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.

The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.
