What This Part Does
The PCV diaphragm regulates crankcase pressure and controls the flow of blow-by gases through the engine ventilation system. On BMW N55 engines, the membrane can become brittle, crumble or crack over time, allowing excess air into the system.
A failed membrane can disrupt crankcase ventilation, change fuel adaptation, increase consumption and cause unstable engine operation. Replacing the damaged diaphragm helps restore pressure control while keeping the existing valve cover in service.

This PCV crankcase ventilation repair kit is listed for BMW vehicles equipped with the N55 engine.
