anyone ever replace the PCV valve?

Its probably easy with the manifold removed, but I defenitly didnt want to remove it.

I accessed the PCV with the firewall panel and the engine cover removed. There was evidence of oil on the manifold top around the PCV. I cleaned the PCV with carb cleaner and the spring loaded valve seemed to be working ok after the cleaning.

I worked from behind the drivers seat to remove the PCV. Thru the firewall, I had to disconnect an electrical connection and remove a bracket and carefully move a hose out of the way but the part was not too too bad to remove. I reached both thru the firewall and down thru the open upper engine cover. Going down thru the upper engine cover, you'll need long extensions for your 1/4 drive sockets to loosen the bolt holding the PCV. As always, the stupid two tab squeeze fitting was a mother to release.

To reattach the PCV, I used a long extendable magnetic "wand" or part grabber to put the bolt holding the PCV in place back in the threaded hole.

It is a hard to get at part.

I found this thread intriguing, I did not know there was a PCV valve on these motors. I have replaced the AOS four times on the Jӓgermobile over the years so I decided to search, remove, and inspect the PCV today. Thanks to wawa and rem503 I was able to find and remove the valve.







It was definitely plugged-up on the spring valve side, I could not get air to move in or out of that side of the valve. I placed it in Mystery Oil for about an hour, hit with some carburetor cleaner, then I soaked it in Mystery Oil again for about 30 minutes. After cleaning I could get pressured air to flow through the spring valve.

Why not just replace it, it is a $20 part at retail............

JFP, how often does the PCV valve has to be replaced..?

I am on my third AOS (80k) and after reading this post, it seems that this could be cause for the short lived AOS.

I already bought the two accordion hoses that connect to the AOS, perhaps may be a good idea to buy the PCV valve and replace it at the same time.

Question: Does the lower accordion hose connects the AOS with the PCV valve..?

Thanks in advance!

We do it when they start to look nasty, or to stick. If someone has suffered and AOS failure with lots of oil in the intake system, we always change them out after cleaning everything else.

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...

So I could save $20 towards my next Porsche.
