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.

I was replacing my oil filler tube on my 2000 996 cab, and I broke one of these hard plastic lines off of a 3 way split.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi everyone. I was replacing my oil filler tube on my 2000 996 cab, and I broke one of these hard plastic lines off of a 3 way split. I went to see where is was connected and the whole line came out in my hand. can anyone identify what this part is, where it goes, and any part numbers to fix them? thanks so much in advance!

POST 2Original post

I believe that one is part of the SAI (secondary air injection system). It goes from that "T" in the photo to the SAI valve which is under the left bank plastic intake manifold. You may be able to get to it by removing the alternator and leaving the intake manifold bolted in place. Otherwise it's impossible to access.
