What This Part Does
The crankcase ventilation unit controls the flow of blow-by gases and helps regulate pressure inside the engine crankcase. A worn or damaged membrane can cause incorrect crankcase pressure, oil vapor issues, unstable idle, and pressure-related oil leaks.
Replacing the membrane inside the ventilation unit helps restore proper crankcase ventilation function while keeping the original housing in service.
