This is Project 9 from the 101 Projects for your Porsche Boxster book.
Well I finally did it… another right of passage as a Porsche Boxster owner. It was one of the more annoying maintenance jobs to date, but I’m hoping that this video will make the job a little easier for you. There are a few videos out there on doing this, but none had the details of HOW to remove the parts. I get into the details of SHOWING you how to remove each part of the AOS and help you with the checklist of MUST HAVE parts before you start.
BONUS MATERIAL: Stick around for the end where I cut the Air Oil Separator apart to see what’s inside.

The job is somewhat easier on a 2.5 liter. On the 2.7, there is another harness in the way. This is possibly the most unrewarding job I ever did on a car.
Did the same last week and used three nights to try to get the whole red seal on the AOS in the engine case. Could not do it despite all my efforts. Good to see that your AOS also left a mm of seal visible. Now I can let that go, it should be fine I guess.
Love the editing with the arrows to point out the bolts and the zooming in to point out the hose clamp!
Why didn't you just do that from the wheel well?
Been there and done that. The hose clamp would definitely help. Thanks for the video!
I found that using a vice grips to hold open the clamp really helps. You can get the clamp lined up really nicely and then release the grip. Those blue pin things are cool too. You can even reset them afterwards onto the clamp with a vice grips.
Great video as usual! I think your dog summed up the feeling of frustration pretty well too π
Apparently this part fails regularly (I believe the diaphragm inside eventually perishes/splits) so replacing it as a part of a preventative maintenance regime is a good idea, rather than waiting for it to fail, especially if you've just bought a Boxster and don't know if it has been replaced recently or not. Tough job though!
Keep up the good work π
great video I loved it
Been watching you vlogs, thanks so much. Itβs been very helpful
Done this. It was a pain in the Frickin' Wazoo! Instead of using the blue pin to hold the "pinch type" hose clamp open for installing, I purchased a regular hose clamp and was able to use a ratchet to tighten it. So how do you know when you need to replace it? With mine, I started to hear a loud noise, like a whistle or a squeal. It was difficult to diagnose the noise because it would come and go as it pleased, regardless of throttle, brake, gear, speed or anything. Also, there was also a much more frequent puff of smoke from the exhaust than normal. I believe I had a leak in the membrane that you revealed in the bonus video. That leak was causing the noise.
