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.

POST 1 / ORIGINAL POSTEROriginal post

My mechanic is advising that I have a leak in the air oil separator and that it be replaced, which apparently is a very expensive repair. My car is a 1999 996 cabriolet with 40K miles on it; I'm the original owner. The car runs great and I have no smoke coming out of the exhaust. As you can surmise, it's not driven that often. I took it in because the convertible top stopped working and told him to go over the car since it's not serviced that often; the check engine light was on and he found a problem with the vacuum reservoir which has been fixed. Any recommendations on what I should do? My inclination is to just wait for something else to go wrong and which requires getting that deep into the engine, then do them both at once.

POST 2Original post

I would not wait - the consequences are too dangerous. Please replace it with the UAOS, it's upgraded and you won't ever have to replace it again. Search this forum for "UAOS", it's about $400 if I remember correctly.

POST 3Original post

A failed air/oil separator can (worst case) cause catastrophic engine failure. The repair isn't all that expensive, the part is cheap, and its about 2-3 hours labor for a skilled person to do it...

POST 4 / ORIGINAL POSTEROriginal post

Thanks, I'm definitely not getting a quote that looks like 2-3 hours of labor and a cheap part. I have another guy that I normally take the car to who's super-experienced but he wasn't available for the convertible top repair as he's on his own and backed up with work. I'll look up UAOS on the forum and then get him involved.

POST 5Original post

If its a tiptronic? I think the labor is more for them because u cant access a bolt. Double check this info i may be wrong.

POST 6 / ORIGINAL POSTEROriginal post

No, it's a 6 speed manual. I found the UAOS installation document and might try it myself since I've done work on the car before.

POST 7Original post

I thought I read on the UOAS install thread that it is doable on a tip without removing the engine, just a pain.

POST 8 / ORIGINAL POSTEROriginal post

Yes, the install doc I'm looking at shows it being done while the engine is in place.
