It looks cheaper than I would have anticipated, so I wanted to double check here before I order it.

To replace the AOS, you should drop the engine a few inches to increase access and also remove the coolant expansion tank and the driver's side manifold.

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

Hi, I am going to replace the infamous Air Oil Separator in my 2001 996 convertible. The car is smoking like it's burning, and the symptoms all point towards the AOS. Question is what I need to buy and where? Only part I found here at Pelican is this one: Pelican Parts - Product Information: 996-107-080-54-OEM Or part no 996-107-080-54-OEM if the link doesn't work. It looks cheaper than I would have anticipated, so I wanted to double check here before I order it. Any advice would be very appreciated! Thanks, Johan

POST 2Original post

Does not look right. Maybe this one 996-107-023-55-M100 Oil Separator, 996 Carrera 2/4 (1999-01), Each Brand: Genuine Porsche [More Info] some DIYs AOS 2002 Porsche 996 - Rennlist Discussion Forums replace from top So I replaced my Air/Oil separator - Rennlist Discussion Forums

POST 3Original post

Is the replacement AOS an improved part or will it eventually fail like the old one?

POST 4Original post

They will all fail eventuality, it made up of plastic and rubber.

I believe it is an improved version but have never had to replace one. Google it and you should get a number of past posts on the subject that will confirm the changes made to the part over the years. The early versions were particularly prone to failure due to weaknesses in the design.

POST 6 / ORIGINAL POSTEROriginal post

Thanks, that looks more like the right one. It's only one of them, right? Regards, Johan

POST 7Original post

1 of these per engine, behind driver on left drive cars.

Since you have a convertible, you already have less access to the engine from the top. To replace the AOS, you should drop the engine a few inches to increase access and also remove the coolant expansion tank and the driver's side manifold. It's kind of tricky to replace. I jhave a write-up on how to do it. Email me and I'll send you the info. [email removed]
