In the final stages of assembly after a valve job among other work. I can't find the torque spec for the intake manifold to intake riser on a 1999 996 C2. Thanks in advance!

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.

Not sure if this is what you need- circled in red

Thanks, yes I have a copy of the work shop manual and that specification. I believe that is the intake riser to the head, which I've already fastened. I actually need what goes on top of that. The black plastic manifold (with the green o rings) to the intake riser. Thank you.

I thought that is what you were asking, I can't find the spec either.
POST 5 / ORIGINAL POSTEROriginal post
What is annoying is the section in the fuel manual that covers the intake distributor lists the bolts just like it does in other parts of the manual. But under install notes there is not a torque value listed, just blank. Perhaps I should just treat it like any other generic M6 fastener, and torque to 7.5 ft lbs. I don't want to damage the green o-rings.
POST 6Original post
If they have o-rings, than yeah, you wouldn't need to torque them that much anyway. I would stick with the 7.5
