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.

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.

BMW Oil Separator Valve | M60 3.0 / 4.0L is a vital component that ensures proper crankcase ventilation by separating oil vapors from blow-by gases, preventing excessive oil consumption and maintaining engine efficiency. Designed for BMW models equipped with the M60 3.0L and 4.0L engines, this oil separator valve helps reduce carbon buildup and extends the life of essential engine components. For optimal results, it is recommended to replace the valve cover and crankcase ventilation system (CCV) when changing the separator valve.

• Effectively separates oil vapors to prevent excessive oil consumption
• Helps maintain proper crankcase ventilation for optimal engine performance
• Reduces carbon buildup and prolongs engine longevity
• Direct-fit replacement for BMW M60 3.0L and 4.0L engines

Ensure the longevity and efficiency of your BMW engine by replacing a worn oil separator valve with this high-quality replacement.

Connecting the cyclone oil separator to the engine valve cover, this hose is crucial for maintaining optimal engine performance. Over time, exposure to heat from engine components can cause the plastic hose to become brittle, resulting in cracks, tears, or splits. These issues can lead to vacuum and oil leaks, triggering a check engine light.

• High-quality replacement for BMW crankcase vent hose
• Ensures optimal engine performance
• Resistant to heat and wear
• Helps prevent vacuum and oil leaks
• Easy to install

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

This tube runs from the oil separator to the lower dipstick tube.

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.
