The BMS N54 Upgraded Replacement PCV Valve is a high-performance upgrade designed to enhance crankcase ventilation and minimize excessive blow-by in BMW N54 engines. Unlike the stock PCV valve, which can degrade over time and lead to oil consumption or boost leaks, this upgraded version provides superior sealing and long-term durability. ### Key Features: - **Direct-Fit Replacement** – Designed for an exact fit, ensuring hassle-free installation. - **Optimized Ventilation** – Improves crankcase pressure management, reducing oil blow-by and deposits. - **Enhanced Durability** – Constructed from premium materials to withstand high-boost applications and prolonged use. - **Boost Leak Prevention** – Delivers a tighter seal than the factory valve, preventing power loss. - **Ideal for Tuned Engines** – A critical upgrade for N54-powered vehicles running increased boost levels. Upgrade your N54’s crankcase ventilation system with the BMS Upgraded PCV Valve to ensure maximum performance, reliability, and engine longevity.

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. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

N54 powered BMW vehicles have two of these tanks, one for each turbo. They accumulate and hold vacuum/air to be used on both turbos. The factory plastic N54 boost vacuum tanks tend to leak and cause problems. If vacuum can't be stored the wastegates will not function, leading to common low boost or overboost faults. We have the solution, the all-new heavy-duty BMS tanks. Specifically made for stock to high-boost N54 engines. Each tank is made from 100% aluminum and features two CNC machined aluminum end caps and are anodized black to complement your engine compartment. Featuring BMS logos, metal barbed vacuum fittings, and integrated brackets for solid mounting in the factory location. Not only do these look awesome under the hood, but they will also last forever.
