Oil Separation & Breather System

Every car has a crankcase vent system that is supposed to suppress oil from making it into the intake ports and combustion chamber. A good functioning system will separate oil from the atmosphere and return it to the oil pan (or collect it in a catch can) while allowing the leftover vapors to burn in the combustion chamber or recirculate through the system. This has always been known as a PCV system (Positive Crankcase Ventilation) but BMW has several other names for it - oil separator, crankcase vent (CCV), and cyclonic separator. Failures in the system will allow raw oil to enter the intake and eventually into the engine itself which can have disastrous effects on engine performance and longevity. As emissions regulations on oil and gas venting have gotten more stringent the PCV systems have gotten more complex and failure prone. And because the CCV is intertwined with other systems you could experience rough running, loss of power, higher oil consumption, misfiring, stalling, or other annoying issues. There is no replacement interval for these so we recommend inspecting your crankcase vent system as part of your regular maintenance routines. Symptoms of a bad crankcase vent are: whitish or yellowish film on the underside of the oil cap, whistling/squealing noises (not caused by a belt), suction on the oil cap that makes it hard to unscrew, large amounts of white smoke from the exhaust, and excessive oil consumption.

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 all the components of the oil separator system together 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. Don't forget to order a valve cover gasket, throttle body gasket, and a new intake boot to make your separator change easier and more comprehensive.

After the introduction of the M52TU/M54 engines, BMW observed an uptick in CCV-related issues, especially in cold regions. Vehicles operating in extremely low temperatures often encountered a blockage in the CCV dipstick hose, leading to elevated crankcase pressure and visible blue smoke from the exhaust. To address this issue, BMW introduced cold climate-specific hoses with foam insulation, preventing condensation and facilitating quicker oil warm-up. This kit incorporates top-notch reproduction cold climate hoses to ensure optimal CCV performance across all weather conditions.

The crankcase ventilation valve, known as the oil separator, PCV, CCV, or crankcase pressure regulator valve, plays a vital role in redirecting oil from your vehicle's intake system back into the engine oil pan. This system comprises numerous plastic and rubber hoses, prone to damage due to prolonged exposure to chemicals and heat.

Designed to tackle or prevent impending CCV system failures, this kit includes four foam-insulated hoses made from durable plastic capable of withstanding heat fluctuations and chemical exposure. Additionally, a new ventilation valve is included for a comprehensive and long-lasting repair solution.

Signs indicating the need for crankcase ventilation system replacement include:

Whistling sounds from the intake manifold, caused by crankcase pressure venting through holes in the CCV hoses. Blue smoke emitting from the tailpipe, indicating oil consumption. Excessive oil usage. Milky or yellowish buildup under the oil cap, suggesting condensation due to ventilation valve malfunction. If you're experiencing misfires, lean fuel codes, decreased fuel efficiency, or noticeable oil consumption, it's advisable to overhaul your crankcase ventilation system. Opt for this reliable system from Febi-Bilstein for a repair that meets factory standards and ensures consistent performance.

Rubber breather pipes in various BMW applications are susceptible to cracking. Over time, engine heat and weather conditions can weaken these hoses, leading to breaks or leaks. This results in significant vacuum leaks that can severely affect engine performance.

Moreover, BMW faces a problem with oil separators freezing in cold weather, particularly if the engine isn't adequately warmed up during driving. Typical signs include a howling noise and subsequent oil leaks.

On M52/S52-equipped BMWs, the factory crankcase ventilation (CCV) system is a notorious weak link. Between brittle plastic corrugated hoses that crumble from heat soak and an internal cyclone diaphragm prone to tearing, a failing CCV leads to massive oil consumption, vacuum leaks, and that dreaded "howling" whistle.

This kit addresses these issues with all new components and hardware. Both oil separator hoses, the cyclone separator itself, the mounting grommet, and the retaining bolts are included. Servicing this system is guaranteed to restore performance lost as a result of worn CCV components.

Kit includes:

Cyclone Separator/Crankcase Pressure Regulator Valve High Performance Silicone Breather Hose Return Hose Mounting Grommet Hex Bolt (3)
