• PCV system are notoriously failure prone, leading to high oil consumption, burning oil, loss of power, misfiring, and high carbon deposits. Signs of a failing PCV include: whistling noises in the intake, blueish smoke in the exhaust, high oil consumption, and thick white or yellow gunk under the oil cap. When it happens on your BMW cars, you can take this PCV Hose Kit for direct replacement.
• The crankcase vent system separates liquid oil from the air inside the engine and intake. When working correctly, oil is removed from the intake air and returned to the oil pan. Oil vapor remains and is burned up in the combustion chamber. Every car has some form of crankcase ventilation, also known as a PCV, CCV, oil separator, and a cyclonic separator.

• BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. Crankcase breather valve is used to purge oil vapor from engine block into valve cover. However, sometimes condensation can cause it to freeze, causing entire oil separator system to fail, crack, and disintegrate. Replace all components of oil separator system together to prevent damage to all aspects of engine.
