I am replacing aos on my 2003 Boxster-S because I had oil dripping from intake plenum (tee) and resonance tube and plenty of oil in the top breather hose.

Question: have you changed that seal whiling changing aos and what’s the best way to get the old one out as the access is very limited.

btw...you do not want to have to replace the lower hose, it isn't an easy job with the engine in the car.

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.

POST 1 / ORIGINAL POSTEROriginal post

Hello, I am replacing aos on my 2003 Boxster-S because I had oil dripping from intake plenum (tee) and resonance tube and plenty of oil in the top breather hose. There was no smoke or hunting idle. The lower breather hose connection to aos is quite wet and I found that there is a seal (not o ring) 996-107-122-00 that can be replaced. Question: have you changed that seal whiling changing aos and what’s the best way to get the old one out as the access is very limited.

POST 2Original post

I have replaced both the top & bottom breather hoses that connect to the AOS. The both have o-rings on them. Never replaced the o-ring unless it was bad and dont believe any of the writeups suggest it either when doing just the AOS. btw...you do not want to have to replace the lower hose, it isn't an easy job with the engine in the car.

POST 3 / ORIGINAL POSTEROriginal post

What year is your car. Does the seal goes in the breather tube or on the aos and tube goes over it

POST 4Original post

He said it's a 2003. The oring is on the hose side both for top & bottom, there is no seal or oring on the AOS for either hose.

POST 5Original post

Stl, I believe that the AOS hoses have their O-rings on the internal side of the connector, I remember lubricating them prior of installation, but that was several years ago..

POST 6Original post

Nope, there are no orings on the inside or the outside. The upper & lower hoses connect on the outside of the male end. O-ring is on the hose end.

POST 7Original post

Yes, the o-rings I was referring to, are are the ones inside of the accordion hose
