  1. Yes yes thought it could be a duff AOS even though it was brand new. I researched 'definitive testing' of the AOS and found that crankcase negative pressure is the only real way to find out if it's ok. My crankcase pressure is exactly what it should be when the AOS is healthy - hence my uncertainty now on what is causing this.

  3. Greetings. I think you will enjoy reading about your car. But don't let everything drive you crazy. Strongly consider getting the IMS fix from LNE no matter what. You will have peace of mind. I found my 2003 C4$ with about 13k miles. Clearly under driven. This can often be the indication of problems to come. Really. Others will tell you this as well. I believed I was gifted with a C4$ with a good IMS. It still looks good sitting on my workbench in the garage. Next to the timing chain tensioners from my 911SC, and the really interesting internal oil pump from the 3.0 engine. I had to fix a main bearing at 130K. Sold car with 325k. All these parts look great, although the IMS bearing is not all that interesting. You need to have one of these things on your bench as well. Most seriously, all kidding aside, if you are thinking about the IMS fix just do it and get over the worries. Just because. Get a bearing for your desk, do the LNE fix and get many more good nights of mostly worry free sleep. Good thoughts. You have a great car. Mine's a 6-speed, clearly my last manual trans. You might put up a pic, the compliments will no doubt be gratifying.

  4. Most likely yes. http://www.pelicanparts.com/techarticles/Porsche-Cayenne/67-ENGINE-Repairing_the_Air-Oil_Separator/67-ENGINE-Repairing_the_Air-Oil_Separator.htm You can buy the membrane for 30 dollars from https://vanos-bmw.com/membrane-94810513107-porsche-cayenne-45l-450ps As for the misfire it's more likely a coil issue try swapping the coil from 7 to 8 and clean both plugs and see what happens, if 8 is OK and 7 is now fouling then you know the coil is the issue. More unlikeky is the no' 8 injector (dripping/blocked) or piston rings worn or cylinder scored or a valve not closing and not sealing properly.
