Torn through the membrane into the engine gets unaccounted mass air flow sensor.
As a result, the engine can be difficult to start, unstable work (especially at idle) can be misfiring, the same engine can get dust, which enhances the wear and tear of parts and mechanisms.
If the whistle is heard in the area of finding oil separator, then the membrane is torn.

The manufacturer sells only the valve cover assembly.

We produce and sell this membrane separately.

Replacement instructions:
Remove the valve cover.
Remove the valve crankcase ventilation (mounted inside the valve cover).

Over time, the membrane separator Porsche dries and breaks.
Through the damaged membrane of Cayenne oil separator to the engine air enters, unaccounted MAF.
In the end, the engine, unstable idling, bad starting, possible misfiring.
At the same time the engine enters the dust from the road which enhances the wear of parts and mechanisms. In the case if you hear a whistle, in the area of finding oil separator Porsche, so the membrane is torn.
The manufacturer only sells the oil separator appears in the collection, which cost about $200.
