When doing any sort of repair or maintenance there is no replacement for genuine factory parts.

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.

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

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.

BMW Oil Separator Valve | E38 E39 540i 740i 740iL M62 4.4L Engine is an essential component designed to maintain optimal engine performance by purging oil vapors from the engine block into the valve cover. This valve features four hoses connecting it to the dipstick, valve cover, and air intake system, ensuring efficient crankcase ventilation. BMW engines, especially in colder climates, are known to experience issues with oil separators freezing if the engine isn't properly warmed up, leading to symptoms such as howling noises followed by oil leaks.

  • Effectively purges oil vapors from the engine block to maintain clean operation
  • Designed for BMW E38 and E39 models with M62 4.4L engine
  • Helps prevent oil separator freezing in cold weather conditions
  • Features four hoses connected to the dipstick, valve cover, and air intake for optimal ventilation
  • Reduces engine sludge buildup, preventing potential damage and maintaining efficiency
  • Durable construction to withstand high temperatures and the demands of the engine

Replace a worn oil separator valve to maintain the proper ventilation and efficiency of your BMW engine, preventing oil leaks and other performance issues.

It's no secret that 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 and the higher the mileage, the more apparent these problems become. The solution to this problem has finally arrived. The Burger Motorsports 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 systems, while others have internal baffle systems that are too restrictive. Some even bypass the PCV system altogether, 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 2025 and newer Gen 3 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 the atmosphere. The mounting locations are selected to minimize the line length, allow more efficient operation, and retain a stealth look. Installation 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.

The Pressure Control Ventilation (PCV) valve is designed to route high-pressure blow-by gases from the crankcase into the intake manifold, relieving excess pressure while recycling gases back into the combustion process. When the PCV valve fails, it can lead to excessive oil consumption, rough idle, and stored engine fault codes. Replacing a worn or faulty valve restores proper crankcase ventilation, smooths out idle, clears codes, and helps keep your engine performing at its best.
