Genuine BMW Crankcase Vent Valve PCV

The Genuine BMW Crankcase Vent Valve, also called a PCV valve or positive crankcase ventilation valve, is an original equipment part. It helps manage crankcase pressure and routes blow-by gases from the crankcase back into the intake system to be burned in the combustion process.

Key Features:

• Genuine BMW original equipment part built to factory specifications
• Regulates crankcase pressure and ventilation
• Helps reduce harmful emissions by recirculating crankcase vapors
• Helps limit oil contamination and sludge buildup in the engine
• Helps prevent oil leaks caused by excess crankcase pressure

A worn or clogged PCV valve can cause rough idle, increased oil consumption, oil leaks, and a check engine light. Replacing it with a Genuine BMW part restores proper crankcase ventilation and supports engine performance, efficiency, and long-term reliability.
