What This Part Does
The PCV diaphragm regulates crankcase pressure and controls the flow of blow-by gases through the engine ventilation system. When the original membrane fails, the valve cover PCV system can lose correct pressure control and cause unstable engine operation.
Replacing the failed membrane and cap helps restore crankcase ventilation function while keeping the original valve cover in service.
