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.

It's no secret that the B58 BMW turbo motors can suffer from oil control problems causing the oil to blow through and coat the intercooler and charge piping, gunking up intake valves and the VANOS system, lowering the effective octane, and generally degrading engine performance. The higher your boost levels the more apparent these problems become. The solution to this problem has finally arrived. The BMS oil catch can. While there are other catch cans on the market they all fall short in various areas. Some are mounted on the hot/turbo side of the motor preventing proper vapor condensation. Others utilize hoses that are too small and runs that are too long to allow proper PCV ventilation causing internal motor/ring sealing issues. Some have insufficient or no internal baffle system while others have internal baffles systems that are too restrictive. Some even bypass the PCV system all together venting crankcase gas and odor to the atmosphere. Most are simply repackaged oil catch cans from smaller/lower power motors shoehorned into place in the turbo BMW engine bay. To solve these problems Burger Motorsports designed their oil catch can kit from the ground up specifically for the B58 turbo BMW application. It features 100% CNC machining with zero welding for a precision fit and long life. The can itself is guaranteed for the life of the vehicle. The hoses exceed the OEM PCV piping in diameter and that flow rate is maintained throughout the entire oil catch can ensuring no excessive crankcase pressure buildup. The BMS OCC retains the factory fully closed loop PCV operation preventing any PCV vapor from leaking to atmosphere. The mounting locations are selected to minimize the line length, allow more efficient operation, and retain a stealth look. Install takes around 20 minutes, includes all required hardware, and is 100% reversible. Simply unscrew the base of the can or use the drain plug to safely dispose of captured oil with the rest of your used motor oil during oil changes. Made in the USA. KIT INCLUDES (1) BMS N54 Oil Catch Can (1) Billet B58 bracket (1) 90º billet fitting/nipple (1) Custom Silicone inlet hose (1) 3.5" Straight hose (2) Stainless steel bracket screws #10-32 x 1/2" internal hex socket head Includes BMS intake silencer delete for installation with factory intake.

An integral part of the emissions system, the PCV valve lets the crankcase breathe. This allows proper intake and exhaust flow, resulting in proper running and operation. When the crankcase vent valve fails it can cause excessive oil consumption, engine fault codes, and poor idle. 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.

Keep crankcase vapors in check and your intake air clean with the BMS Oil Catch Can Oil Filler Cap Dual Vent Connection Kit for the Gen2 B58. This upgrade ditches the flimsy factory venting in favor of a precision CNC-machined billet oil filler cap and dual-vent fittings engineered to handle increased crankcase pressure under boost. By diverting oil-laden vapors into a catch can instead of back through the intake, this system helps minimize carbon buildup, reduces oily contamination, and promotes more consistent performance as power levels climb. High-quality hoses and fittings ensure a secure, leak-free install that won’t collapse under pressure and maintains a clean, OE-plus appearance in the engine bay. An easy, effective upgrade for B58 enthusiasts looking for cleaner operation, improved engine longevity, and proven performance-focused design

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.

Each tank is made from 100% aluminum and features two CNC machined aluminum end caps and are anodized black to complement your engine compartment.
