What This Part Does
The crankcase ventilation valve regulates pressure inside the engine crankcase and controls oil vapor flow through the PCV system. When the diaphragm fails, oil mist can enter the intake system and crankcase pressure can become unstable.
Replacing the failed PCV component helps restore pressure regulation, reduce oil vapor issues and support stable engine operation.
