11127565284 Crankcase Ventilation Valve for BMW N54
This crankcase ventilation valve is designed for BMW N54 engines using OEM reference 11127565284. On the N54 engine, the PCV valve is built into the valve cover and is normally replaced only together with the complete cover in the original design.
This replacement valve is inserted into the valve cover and secured in place, allowing targeted repair of the crankcase ventilation valve area without replacing the full valve cover assembly.

- engine breather valve
- valve cover PCV repair component
- BMW N54 crankcase gas ventilation valve
What This Part Does
The crankcase ventilation valve regulates pressure inside the engine crankcase and controls the flow of blow-by gases through the PCV system. On BMW N54 engines, this valve is integrated into the valve cover, so failure of the PCV valve can affect pressure control, oil vapor flow and engine stability.
Replacing the failed valve helps restore crankcase ventilation function, reduce vacuum-related symptoms and keep the existing valve cover in service when the cover itself is still usable.
