After nearly 2 years, I've finally replaced my AOS!

[CJ_Boxster]

Well at about the 3rd month of ownership 2 years ago, I realized I needed a new Air/Oil Separator because of 2 reason; 1) Puff of blue smoke every month or so. 2) leaking lots of oil from the bellows tube/accordian tube at the rear of the engine.


Between the time i noticed and the day I finally replaced the A/O Separator I've had a bad vacum leak and idle became progressively worse as time went on. So I bought the newest A/O S and J-Tube... Reset the cars computer and started her back up and BAM....... smoothest idle I've heard & felt from this car in over a year. And i can feel alot of lost HP come back in the Hi RPM's that wasnt there due to the vacum leak. I've driven it 98 miles since i did the AOS replacement and no CEL's and idle is still smooth and always just acouple hairs below 800rpm mark on the dash.

I've also noticed that Im not blasting through fuel as quickly.

Replacement took me about 40 minutes counting placing the top in service mode and replacing all the covers when i was finished.... I also pressure washed all the year in a half of oil and dirt stuck to the right-rear side of the engine as a result of the leaky AOS.

Glad it fixed all of that for you!!

Sounds like a new car.

First, Have a shop to your disposal that has a lift! Without that, your in for a fun time reaching under the car for those 2 bolts, hose clamp and lower AOS snap-on hose.


Also, i was trying to rush alittle so i can post a good time

Ouch! I took my time and didn't have a lift and it only took me about 2 hours... maybe I should open up an independent shop? Sheesh.

Dayum! talk about taking it up the @$$. You should've researched it on the forum before.

Where is this AOS located? Do you gain access to it from underneath the car or from on top? I thought I read somewhere that it was accessed from underneath?

Well you have to widdle your arm through the right rear suspension over and under the rear axle and remove 2x 10mm bolts, then unclamp the bellows/accordian hose from the engine, then unsnap the plastic hose that snaps into the side of the AOS.

Once your done with that, goto the top of the engine and unsnap the jtube and start pulling the AOS up out of the engine and move the wires and hoses out of the way with your other hand as you carefully pull the AOS up off the engine.

The AOS is a topic we'll be covering in our instructional video series that we'll be shooting in February... No more 900.00 charges to do this job from Porsche! I'll show you how to do it in less than 20 minutes, go over tools needed and share a few tricks.

Same thing goes for brakes, oil changes and all the other service related items :-)

^ sweet. those are all items I would like to address on my own with the boxster.

CJ, Thanks for posting. I think I am going to pick up a new AOS soon and swap out to old one this winter.

Jake, will this be available through your web site? What other goodies have you put together or is it all yet to come? I do NOT like working on my cars, but will take on whatever I think I can figure out just to not feel foolish with my money. I crave information and instruction because otherwise I stare at photos and wonder what I am looking at and just where is the gizmo that I am supposed to be seeing.

On a side bar, what are your shop hours? I think it would be cool to come take a peek, but I probably wouldn't be able to get away during the week.
