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.

But when I did the 105K maintenance back in Dec, I replaced the AOS as my engine/trans was out.

Suggestion · Original poster

I did the AOS check of taking off the oil cap and the engine seemed to run fine after a second of initial rpm changing with it off, there was a little suction but not to much.

I had no oil consumption that I could detect and I had very little idle change with the filler cap off.

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.

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

  • Rennlist: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 2Original post

not sure maybe a air conditioning hose I can't tell

POST 3Original post

It may be the seal on the cam position sensors.

POST 4Original post

That's one of the breather lines from the AOS. Mine was leaking a some oil from there when the AOS was bad. Rick 99 996C4 87 944S

Did you also have extreme oil consumption? I did the AOS check of taking off the oil cap and the engine seemed to run fine after a second of initial rpm changing with it off, there was a little suction but not to much.

POST 7Original post

+1 for an AOS tube IIRC - AOS failures cause differant symtoms on differant cars for some reason. Oil consumtion is one thing it can lead too as well as noises, white smoke, small leaks, poor running or nearly any combo of these. have you had yours changed? - Its a fun job !

POST 8 / ORIGINAL POSTEROriginal post

Quotes source post: 7645037

havn't had it changed and it sure looks like a $$ job to get at it.

POST 9Original post

I have heard some shops can do it in ~4 hours (for C2 6 speed) - it took me longer it can be a good DIY if you have medium skill and some tools. Costs about $100/150 for the AOS.. you might need a new line or two

I had no oil consumption that I could detect and I had very little idle change with the filler cap off. But when I did the 105K maintenance back in Dec, I replaced the AOS as my engine/trans was out. I later opened the AOS with a BMFH and there was a 1/2 inch split in the rubber diaphram. I have pictures I can post. Rick 99 996C4 87 944S

POST 13Original post

yeah pictures.... You can see in the bottom 2 pictures the small split in the diaphragm. Rick 99 996C4 87 944S
