Exactly what I was working on today. I made the mistake of buying the wrong o-rings. Now I see I should change the big thin one on the top also. I'm off to order more parts. Thanks for solving my problem.
Thank you for sharing. I performed a smoke test on my ‘83 and it looks like I have vacuum leak at the bottom o-ring. Guessing I need to remove the intake to get to it. The leak is keeping me from having fun with my 944. Thanks again and take care!
Thanks for the video, I was surprised how simple it was when I took mine apart: have you a part number or description of the o ring for the top of the body? I cant see this in the spare parts catalogue.
They’re made by a company named Parker. Part number on the package has been obscured but starts with S1138 AS5...8 - 151. Very close to 80 mm in outer diameter and 3 mm wide.
My race car has an oil catch can that attaches to the top of the AOS so that oil vapors go there instead of to the Jay boot. That keeps my throttle body and intake manifold much cleaner.
@@TheTr0uble No, a single dedicated hose to the catch bottle which has an air filter on top of it. May need to adjust your mixture, since it's like running with the oil filler cap off. Keep in mind, mine is a full 944 Spec race car
Not the easiest thing to remove that brittle plastic top cap to replace spaghetti seal. I broke a small piece of the edge of the cap but thankfully it's not part of the sealing surface. Also some of the 6 locking tabs got beat up during removal. I'm thinking that if I can get at least 4 of the tabs to re-engage with the bottom part of the canister then I should be able to get an air tight seal with the fresh new o-ring installed. It should be an improvement as I know that air was getting past the original black oring.

You're welcome, dude! Keep having fun with your 944.

Any part numbers for the internal seal?
Would it be beneficial to add an Oil catch can after the AOS to the Throttle Body???

So you “T” off the top of the line to the AOS a return on the Throttle Body???

Sounds like a good plan.
