Does anyone have a pic of the oil separator bellows?

[AUDIOGUY]

I am curious where to find the hose for the Oil separator bellows. I had my 1128 1130 codes come on yesterday. I will clean the MAF this weekend but was curious where to find the bellows and check if that is leaking...

Also, after clearing the codes, is it normal for the car to run crappy till the DME adjusts???

Thanks!

Hi,

Here's a few links that might be helpful:

Also, after clearing the codes, in my experience, it's a normal occurence. (e.g., after I changed out all four of my O2 sensors). Maybe a few of the other folks out there can give you some input.

Anyway, good luck with that! Hope the links are helpful!

bellow are just inside the right rear wheel. Tough to see unless the wheel is off and vehicle up on lift/stands. Find the AOS from the top side... bellows directly below. If you have had the AOS replaced once or your car is '00 or newer, the disc on the top of the AOS will be vertical not horizontal.

even if bellow aren't leaking, doesn't mean AOS isn't bad as it fails internally too. Pull the j-tube (connects to the throttle body) and look for more than a misting of oil.

Here are instructions on how to R&R from Mike's Focke's page:

PLEASE PLEASE PLEASE listen. I DYI'd the AOS last year and did not change the bottom tube because I was told it was always the top the had the issue. Recently the car had been dumping oil on the ground. I just had a friend of mine who is a Porsche cup car mech. dig into it to find the root of the issue. After removing a ton of oil from the engine compartment we found the bottom tube had cracked and split and was indeed the issue in question. So if you do do the AOS PLEASE change that piece also. Trust me otherwise you will not drive the car and the drop another grand into finding what the problem is.

Hi,

I'm thinking about purchasing AOS items for DIY this Spring and would like to know w/c tube you are referring to?? Do you (or anyone else) have a picture of this tube? ...a part number would be very helpful as well.

Thanks in advance.

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.
