Does anyone have a pic of the oil separator bellows?

The bellows (circled in blue below) come with a new AOS when you order part #996-107-023-04 ($76.50 last summer from Sunset). The newest j-tube (not 100% required if yours is clean) is part #996-107-145-06 ($24.22 again last summer from Sunset).



Here's a link to the DIY I used for replacing mine.
Mike Focke's AOS Replacement DIY

I definitely recommend doing this a preventative maintenance. Took me under 1.5 hours to DIY at a total cost of $110 (including shipping on the parts). Dealers are known to charge $500-800 to r&r. Definitely DIY.... as long as you know how to take a wheel off and put the back end up on jack stands (not in that order though )

Incidentally, You can order the bellows on their own (don't have p/n). However, if you're going to all the trouble to replace them, it's in your best interest to replace the entire AOS. The bellows do fail on their own, but the bladder inside the AOS is much more likely to fail.... first.

Hey BB,
I appreciate the response...hopefully, that's the same tube that JP-in-St. Louis was referring to also.

It is - you're good to go.

As mentioned, it's possible to get the AOS w/out the bellows. In fact one of the previous iterations (Porsche is currently on 5th version, 4th revision based on the .04 part # ending) might not have automatically included the bellows. Not sure but could be possible.

Bellows are known to go bad on their own w/ or w/out the AOS being bad. Thus why you can buy them separately. Just order the part # I listed above and you'll have what you need (plus a dab of grease for the rings) to do the job completely.

Go to it

when i had those codes it ended up being a faulty MAF...
swapped that and its back to normal, although the Jtube wasnt secured good once i opened the engine compartment for the first time, so double check that, its also hard to put back in place.
Good luck

How does the plastic fastener work that connects the j-tube to the AOS? Does it twist or do you just pull it off? I've not seen a connector like that and don't want to break it.

Anyone know the answer to my question below?
Thanks.

squeeze where it's not filled in on the ring and pull outward wiggling it back and forth. Don't worry, you won't break it.
