If you are changing your AOS, order new clamps...

[suburban99]

I removed my 2 year old AOS from my 1997 Boxster to replace the seal that goes between the AOS and the engine block.

Also ordered a new bellows, and 2 new clamps for the bellows, I ordered 1 top and 1 bottom clamp. The bottom clamp comes with a small plastic appauratus the holds the clamp open until removed. Makes changing the AOS much easier. The last time I changed my AOS and the bellows and clamps I did not get one of these. I clamped a small pair of vise grips to the clamp to hold it open...maybe they have been around for years...? anyway here's a picture.

When you order an AOS, it comes with the bellows and the clamp (w/ the blue contraption that holds it in the open position. I'm surprised your last AOS didn't come with the bellows.

Were you getting P codes associated with a torn bellows?

No, the seal for AOS to the block was leaking. I removed it to change the seal. Replaced the o rings in the j tube and decided to change the bellows as well.

I used pipe clamps instead of porsche's style; tons easier to get into place and tighten and will be a lot easier to replace in the future if my AOS fails again.

Hi, is the new seal that you are referring to between the AOS and engine the orange one? And does it come on the new AOS?

Does anyone know if part # 996-107-926-00-OEM (the Air Oil Separator, High Performance Version) will fit a 2002 Boxster S?

If not, is there another high performance AOS that will fit?

I have a 3.2 that has been punched to a 3.8 getting transplanted into my 2001.

Thanks,

David

No it won't fit. It will only fit the 03-08 Boxster/Cayman engines. I custome make a solution for my customers, but have nothing readily available. Tell your shop to take a look at how the new 9A1 handles the AOS. This will give them a good idea on how to come up with a solution for your M96 based engine.
