The most challenging part was disconnecting the old hose from the AOS body because of the pinch connection.

I only had to remove the throttle body which made running the hose pretty easy back to the AOS with the engine lowered.

Did smoke test after replacing one of the stainless steel hose clamp on the throttle body and no leak.

I did the smoke test through it but i didn't see any leak.
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.

Maybe coincidence but i did recently installed the UAOS and had filled up to max dipstick level.
The other day i noticed this drip on the right rear most side of engine. It appears and feels to be oil.
I am thinking leak from spark plug?
No engine light.
Seems to be very tiny amount of drip over past two days.
Ideas?
I guess there is always a drama to solve.
There is a pcv valve above that that connects to a aos pipe . If you look from the top right with the airbox out , it's behind the cooling pipe . It won't be the pcv valve but the O ring in the pipe .
be aware the size is wrong on the parts list for that o ring . It's actually the larger size it says for the other side of the pipe .
i had a go at looking for this connection but i couldn't find it
um maybe you can mark an X for me on the pic below...
i did notice quite a bit of oil at a ignition coil.
yea ok the damn ribbed plastic pipe (crankcase breather hose) i think has a crack.
I did the smoke test through it but i didn't see any leak.
probably not enough pressure to make the leak noticeable.
ugh. will it be a b*tch replacing this?
yay. but i do love working on my 996...yea i do.
I think it would be an absolute ****ing bitch to replace.
It snakes under/between the passenger-side intake manifold. Maybe you can remove and install it without touching that intake manifold, but I think the job would be much, much easier if you removed it. And the driver-side manifold needs to be removed. You�re pretty much doing the AOS install all over again.
But it will be easier this time because you�ve picked up the experience and confidence from doing it before.
Why don't you try to fit the 997.1.... 3.6 pipe onto your 996.....If it will fit will be much easier than snaking the other all up under and through the intake...
Part # 997-107-147-02 and connector piece Part # 996-107-047-01
This pipe circles around behind the intake then up the passenger side and straight down into the head....
Completed the cross over hose replacement this evening. I only had to remove the throttle body which made running the hose pretty easy back to the AOS with the engine lowered. Did smoke test after replacing one of the stainless steel hose clamp on the throttle body and no leak. Good to go I hope. The most challenging part was disconnecting the old hose from the AOS body because of the pinch connection. I found that this was best accomplished from under the car looking above to the AOS after removing that single electrical connector and its mount out of the way.
