Porsche Cayman Gen2 987.2 AOS valve change. In this video I show you how to replace your Air Oil Separator Valve. Part number P0PB115099A and costs approximately $75 inc vat from an OPC Porsche Centre

This is fairly straight forward and you don’t need that many tools.

First you will need to remove the top and side engine covers to gain access to the engine.

Step 2 is to remove the breather hose, there are two points at the plenum just after the throttle body and then the main connection at the valve.

Step 3 is to remove the two E10 bolts that hold it in place.

Step 4 pull the valve up, it’s quite though and will come out with a pop.

Step 5 is getting the valve out, this is a bit tricky and you need to get it out in a particular way. Turn the valve upside down and while bringing it out, turn it anti clockwise.

Fitting the new valve is the reverse order, just to note when pushing the valve in, it is rather tough. I started the two bolts to help line it up so it was correctly positioned and started to wind them in by hand. After that you can push it into place.

Job done... :)
