Klifex Oil Separator Membrane Compatible with Porsche Cayenne 4.8L M48.51 94810723653, 94810723652. Diaphragm diameter: 85mm
Please note that this diaphragm is not suitable for M48.01 motors (if your oil separator has 1 outlets for the crankcase ventilation pipe, then you have an M48.01 motor).
Over time, the Porsche oil separator membrane dries up and breaks. A damaged cayenne oil separator diaphragm enters the engine, which is not accounted for by the MAF. As a result, the engine runs unstable at idle, does not start well, and misfires are possible. At the same time, dust from the road enters the engine, which increases the wear of parts and mechanisms. If a whistle is heard, in the area where the Porsche oil separator is located, then the membrane is torn. The manufacturer sells only the assembled cayenne oil separator, which costs about 250 usd. We manufacture and sell Porsche oil separator membrane separately!
Repair instructions:
1. Remove the cayenne oil separator.
2. Install a new membrane to replace the torn one.
3. Reassemble in reverse order.
At the first start, after replacement, the motor may not work stably (this is due to the need to adapt the fuel cards).
After the repair of the oil separator, the valve is restored to operability, and the leaking of unaccounted air is eliminated. The ECU needs some time to correct the fuel maps. Let the engine run for a while and then restart it.

my PCV gasket blew, this was one of the few online options. Slightly larger than oem, the edges need to be trimmed for it to fit into the housing. The support bracket is already integrated into the new gasket. So far its been 500 miles and no issues. Installed on 2010 Porsche GTS, 4.8L V8 non-turbo.
