One of the causes for unstable idle mentioned on the Brad Anders' site is a sticky or missing PCV. I have been able to reduce my hunting idle to the point where it slightly fluctuates after AAR warm up before the engine heats up. After it is good and warm I have a rock solid 950rpm idle. I have never investigated the PCV and have not been able to find any posts about it. Where is it and how is it cleaned/fixed/replaced?
Thanks, M |

Its on the oil filler tower. The white plastic valve, you can remove the tower and unscrew the valve and take it out. I got a new one from the porsche dealer for about $12.

If you have a 75-76, you probably don't have one.

You are correct, it is located on the oil filler for your year
Here is the part number: 022 115 542 Here is the lowdown on the PCV valve: http://members.rennlist.com/pbanders/PCV.htm Call your local porsche dealer, they will probably have to order the part. |

Found it! It really was not all that cruddy and the little disk on the bottom moves easily on the spring. Just cleaned it off and put things back together.
Thanks for the guidance. M |
