The PCV becomes leaky over time. Inside is a membrane that becomes porous and then ruptures. Consequence, charge pressure is lost.
Leaky PCV valves cause the charge pressure to escape into the crankcase, which not only reduces engine performance, but also creates excessive overpressure in the crankcase. This can lead to further leaks in the engine. Furthermore, it can lead to rough idling. A new PCV prevents creeping loss of boost pressure via the susceptible standard crankcase breather valve.
We always install a new gasket, therefore the PCV always comes with a new gasket. We recommend the control every 10000km and in the ideal case to replace the PCV also directly.
