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.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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

I need help with understanding where some vacuum lines go on my 1999 Porsche 996c4. In the attached photos I have indicated the numbers of items that I need help with and some that I think I understand. I have looked at all the YouTube items that I could find, diagrams from suppliers and the manuals without much luck. 1. Not used 2. Connect where? 3. Top of AOS goes to T near coolant container 4. Goes to the Intake Manifold 5. Connect where? 6. Connect where? 7. Connect where 8. Goes to the Intake Manifold

POST 2Original post

Hello Today im changing my coolant tank, and im almost finished, but when i was about to fasten the innlett pipe i discoverd a vaccum line i dont fint a place to put. Can somebody here help me figure out where it should go?

POST 3Original post

Having the same problem but 1/10 of yours...I only need to know where to connect one hose. So I'll wait with you on this hoping I'd get some help as well with my 1 single hose....

POST 4Original post

My guess is probably the line off the plenum tk this check valve. Here is a pic that may help

POST 5 / ORIGINAL POSTEROriginal post

There are three lines. One goes to the back side of the intake manifold, another to a vacuum source and a third that goes to the white piece that goes to the front of the intake manifold. At least that is what people have told me. Good Luck

POST 7Original post

Thanks Bill99. Did some more research and found this YT Video. It basically shows how to dismantle the whole 996 engine so it may help you figure out where those hoses go... You Tube My question / issue was answered in Step #9 5:20 sec. in the video.

POST 8Original post

Looks like it goes to your diverter valve. this would explain your boost issue..

This is a source reference. Confirm exact model applicability in the original material.
