What This Part Does

This repair kit replaces the failed internal diaphragm inside the oil separator / PCV system. When the original membrane breaks down from heat and boost pressure, the crankcase ventilation system can no longer regulate pressure correctly. Replacing the diaphragm helps restore proper ventilation and engine operation without replacing the complete separator assembly.
