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. When the valve fails, pressure imbalance can lead to rough idle, oil consumption, oil leaks and vacuum-related symptoms.

Replacing the failed valve helps restore proper crankcase ventilation and keeps the existing valve cover in service when the cover itself is still usable.
