BMW E46 Crankcase Pressure Regulator Valve | S54 3.2L Engine is a crucial component that ensures proper crankcase ventilation by regulating oil vapor flow into the intake manifold, preventing excessive oil consumption and buildup. Designed specifically for BMW E46 models with the S54 3.2L engine, this valve helps maintain engine efficiency and performance. BMW engines are known to experience oil separator freezing in cold weather if not fully warmed up, which can lead to howling noises and oil leaks. To ensure a thorough repair, replacing the valve cover gasket when changing the separator is highly recommended.

  • Regulates crankcase pressure to prevent excessive oil consumption

  • Reduces the risk of oil separator freezing and associated leaks
  • Direct-fit replacement for BMW E46 models with S54 3.2L engine
