SecosAutoparts Valve Cover Cap Repair Kit 94810513206 94810513207 Compatible with Porsche Cayenne 2003 2004 2005 2006 2007 2008 2009 2010 Vapor Separator Diaphragm Seal Membrane

Requires a bit of shaping a rounded section to clear the vacuum tubing but worked on my 957 v8 Cayenne. I used a dremmel with a small sanding drum. The plastic is not the strongest so be careful when shaping. The gasket portion seemed an exact match to the one I removed. All sealed well. No long term reviews as I just installed yesterday.Also, I was not able to remove the old cap without it cracking. Likely due to age and being brittle. Just be ready for it to break.

Bought this as it seemed like I was smelling some fumes on startup/idle with maybe some rough idle, and it so far seems good. Replaced my existing diaphragm, spring, and cover with this kit. Everything seemed to be the same essentially and fit as expected on my 2004 Cayenne S.I guess time will tell, but hopefully this holds up in the long run as it's not exactly complex/complicated.

Cheap alternative to buying the whole drivers side valve cover which is the only oe option.Cap is decent quality, pretty close to being an exact copy.The diaphragm which is what i really needed was a bit thicker in gauge, so not sure how that impacts how it works, and the spring was longer.I used the new diaphragm only and everything seems ok, although since replacing I have been consuming more oil, coincidence or something else?Oh, almost forgot, the round fluted plate that sits on top of the diaphragm, it was totally warped, garbage, so reused my original one.If you need a new cap this is fine as i think that's about all this kit it good for.

The media could not be loaded.  After install my car makes a farting noise or like a dude moaning when turning off the vehicle. Also now has a high pitch whine to it when runnjng. Probably due to the loose fitting cap. The original cap fits very tightly, but this one you can move around easily. Would not recommend this part. I installed this after my return window im pretty sure, so now im stuck with it. Everyone on the porsche forums say that buying this is a mistake and i wish that i would have listened.

The internal diaphragm and spring are perfect and fit like a charm. The black retaining cap that holds the diaphragm and the spring in place is too large. It does not securely fit on the tabs that hold it secure to the valve cover. I am going to have to see if I can order or find an oem one to replace this one because it just does not fit correctly and I am worried about vacuum leaks.
