So I could save $20 towards my next Porsche.

JFP,

By any chance do you have the P/N for the PCV valve for a 987 ('07 CS)..?

Thanks again!

PS I tried looking in Pelican's but they show everything else but a PVC...

I'm not sure as I am away from the shop at the moment, but I think your car uses a different method than the M96 engines did, which may be why you did not find it on their website. Perhaps check with a dealer tomorrow.

They stopped using this valve on the Boxster I believe on the 2003 models. They switched to an open fitting. This is what they look like.

Porsche still lists this part as a valve ? is it valve or just an open fitting ?

Two days ago, I finally replaced the two accordion hoses that connect to the AOS and cleaned the engine as the bottom hose was leaking underneath the intake plenum and the top hose had a pinched o-ring where it connects to the AOS.

Question: I noticed that the engine runs smother and has more power, however is this indeed by the fact that the engine vacuum helps the piston rings seal better, therefore makes more power? Or is just my imagination..?

This part is inexpensive : 996 107 047 51
Connection Piece for Oil Separator Vent Line 99610704751 - Genuine Porsche - 996-107-047-51 | Pelican Parts
BUT it is very tedious to replace. Cleaning it may be foolish because of the R&R issues.
1. We really need a Test Method to determine if it is malfunctioning.
2. The later open valve 996-107-047-00 - is it considered an upgrade/substitute for pre-2003 cars ?

3.We also need to decide on the while-you-are-in-there list .As Gilles mentions- the Accordian hoses or their O rings are also problematic.

I just got mine changed thanks to wawa and Jager. The bolt was real easy. It popped out of the hole easy too. I used hose pliers for that but you can probably just pull it out. The trick to disconnecting it from the hose was to turn it 90 degrees so you can grab the vent and hole with your left hand and squeeze the tabs with the right hand. Getting that grip was key because it is so tight in there. I also warmed it up with a heat gun and lubed it with silicon spray to help with removal.
