How do I get to the internal ring? I have the whole unit off right now, and the top part where the hose connects appears to snap off somehow, but im afraid of cracking it....

I'd like to know how to get the top off too w/o breaking it.

You need a couple small flat blade screwdrivers. Just poke them into the slots on the lid and eventually itll come off. Mine took a fair bit of uhhh brute force so I might end up slopping some RTV sealant on there to play it safe.

 

Thank you Brian

anyone have a extra air/oil separator i could buy off of them.

 

The one I got to replace it has an ID of 78MM and its 4MM thick, just a plain donut O-Ring (its not "rectangular" like the original one).

 

will donut work on the other two? cause I cant find any "rectangular" in town...

 

The other two are Porsche parts, so it might be harder to find a GOOD standin. Porsche doesnt sell the oring that goes between the cap of the AOS and the body.

 

gotcha. Thanks!!!

 

Is there a good procedure out there that talks about how to replace the AOS seals? Currently have the intake off and I was wondering if I can replace these seals or if there are more things that need to be removed to get this done.

 

Actually this is pretty straight forward:

1. Disconnect the scavenve hose.
2. Remove 3 13mm bolts.
3. Pull the AOS out of the block.
4. Clean the AOS ports on the block
5. Remove old O-Rings
6. Clean AOS
7. Install new O-Rings
8. Install AOS
9. Reconnect scavenge hose
10. Have a cold one

 

i was pulling mine off when doing my rebuild and woops broke it so i need another one but no way i am paying the price of new for one.

 

daniel, sorry to hear that. Can you tell me what happened or if there is something that I should be on the look out for? And thanks for the instructions Cliff, almost makes this sound easy, which is kind of frightening.

 

well i feel like a dumbass doing it so it was my fault. U know the bolt that connects to the side that the hose is connected to the AOS. Well i was trying to take off that bolt and when i did it pressure on the hose and plastic of the AOS and snap it broke.
