Well, I joined the party... I've tried to replace the membrane as well without success.  I couldn't get to the last triple square, and maybe somewhat stripped the middle one. I may attempt it again with moving the coolant hoses..  If not, I'll be taking it to the dealership for the valve cover install.   I have no codes, but the whistling seems to be getting worse.  I like the 957, but this job is a pain for sure, gone are the days of Autozone 10.00 PCV valve pulled from the top of valve cover, 2 min install..

Here is a follow-up and a few learnings from that job. First, never use electric tape to temporarily fix the crankcase  breather hose while waiting for a new one to arrive...tape melted and I got a huge vacuum leak on my way to work. Duct tape is the way to go 👍

Secondly, despite replacing my PCV valve which I knew was bad, the CEL came back with the dreaded P12A2 code. Now, to think I did all that work for nothing was a bit upsetting to say the least. I ordered a new fuel pressure sensor that I have not installed yet. Meanwhile, I checked my fuel tank cap and noticed it did not close tight, because the o-ring seal was all shrunk and cracked. Knowing this too can cause a P12A2 code, I swapped with the gas cap from my 911, just to try. I cleared the CEL code and went to work with the Cayenne. And bingo! The CEL light did not turn in on my way back as it usually does. So, before taking off your intake to change your valve cover, check you gas cap first would be my advice 😎.

      My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?

      Hi there, my Cayenne is telling me my driver's side door is open when it is not. This is causing the dome light to stay on. Not sure what the issue is and if can be fixed easily. Any info given is greatly appreciated, thanks!

      Hello everyone,
                Does anyone have or know where I may have the bolt torque specs for a 2008 Cayenne Turbo? I need pretty much the specifications for all the bolts and nuts that would be included in a block replacement. I'm getting the back rebuilt by 928 Motorsports and reinstalling with an experienced friend. However, it's nearly impossible to find the specs for these motors. Additionally, if there's a place where I could find a complete 957 workshop manual, could someone please advise? Thank you.

      Just wanted to say thanks to the community helped answer some questions about the scoring on my 2008 CTT 957. My next question is, does anyone know where I may purchase a complete engine seals and gasket kit for a 2008 Cayenne Turbo? Or if these are unavailable as a whole unit, had anyone rebuilt their engine from the cylinder scoring or something similar and have a parts list of required seals and gaskets which need changed? Additionally, are there any other suggestions on parts that I should change some I'll have the motor apart? Anything would help at this point. Thanks
