Part Type
- crankcase ventilation valve
- PCV valve
- engine breather valve
- crankcase pressure control valve
What This Part Does
The crankcase ventilation valve regulates pressure inside the engine crankcase and manages the circulation of blow-by gases back into the intake system. When the valve fails, crankcase pressure can become unstable, which may lead to oil leaks, increased oil consumption, rough idle, and reduced engine efficiency.
Replacing the failed valve helps restore normal ventilation system operation and supports stable engine performance.
