Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Since I'm in the process of putting my engine back together I had to trace the vacuum lines working on the pics I took during dis-assembly. The pic is too big to load onto Rennlist so here is a link to the labeled composite picture for anyone that needs a vacuum line reference for a 99 C2 Manual. http://www.oz951.com/public/emmypics/enginedrop/vac.jpg

POST 2Original post

Thanks. Looks and sounds like you are making some headway with your Porsche projects, well done.

POST 3Original post

That's nice and easy to see thanks! One point, I have a 99 and the three way connector is actually a four way. To add to the photo: the fourth line goes to a change over valve seen here:

POST 4 / ORIGINAL POSTEROriginal post

Ed is that changeover valve something to do with the aux air pump (I don't have one on my car)?

POST 5Original post

Yes it goes to a hose connected to the air pump. See here: Diagram from thread: AOS replacement I've seen both, thought it would be good to let people know in your thread they're not nuts when some might see the four way connector. Because I went nuts when I was finding three way connector photos. Either I'm up late or you're up early.

POST 6Original post

thanks for posting this excellent diagram. a couple hoses disconnected when i was playing around in there and i didnt know which went back where. kudos dude

POST 7Original post

Hi CDLVancouver, i see you just done some work on your 996. I'm replacing my AOS now. I have a broken hose and a couple of other issues. Tell me, from the diagram, does "30" goto the front rubber sleeve plenum and "29" go to the vacuum tube on the rear resonannce tube?

POST 10Original post

the image that helped me the most was the first one attached. very easy to figure out. i only had to reconnect A and B in that image to the back of the plenum and by the vaccuum cannister. bit of effort to get there though
