Air - Oil Separator Diaphragm
Porsche Cayenne Air Oil Separator Diaphragm
Check pictures attached to determine the correct diaphragm for 4.8L


 
This is the replacement diaphragm for the air oil separator on the Porsche Cayenne V8 engines. With time, this diaphragm will tear and cause a vacuum leak that will affect the performance of your Cayenne. Porsche does not offer this diaphragm as a separate item and you must buy the complete valve cover at a cost of over $600.

Note: We've discovered that there are 2 versions of the 4.8L engine. If the cap is closer to the front of the engine, it uses the 4.5L version (see picture #3).

If the cap is closer to the middle of the engine, use the 4.8L version (see picture #4).
