The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition.

The factory hoses offered through BMW are plastic and will yield the same results of becoming brittle and damaged over time. Our solution is a premium replacement that will outlast everyone of the OEM replacements. Our Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to ensure your S54 is free from vacuum leaks and performing properly.

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.
