Porsche Cayman Boxster 987.2 How to Remove and Replace the Air Oil Separator
Vložit
- čas přidán 23. 06. 2019
- My 2009 Cayman was idling rougher and getting smokier than usual at startup. Both tell-tale signs of a worn air/oil separator. Here's how I replaced it in my home garage. While this applies to both Caymans and Boxsters, note that this AOS is an updated design that's different from the 987.1 units.

Did this over the weekend and man let me tell ya you made it seem like a walk in the park with the AOS when you said rock it out and be patient lol, I had a helping hand with my gf and still needed both of us to he-man it out. Thanks for the walk through though!
Glad it helped. Cool that your girlfriend got into it!
I had a heck of a time getting the new AOS to seat properly on the engine. I found a tip on a forum to heat up the pipes and o-rings with a hair dryer...after a few minutes (and plenty of lube) the new unit seated with a satisfying "pop." Thanks for helping us DIYers to tackle intimidating projects.
Thanks for the tip!
always nice to see the how-tos. Suggested edit: show the startup before (with smoke and rough idle), and after.
Good suggestion...If only youtube would allow you to revise after posting ;). Will keep in mind for future vids...
So glad I found this video! I just completed the job on my 987.2 Boxster S and agree with @Happy Time that the Boxster is a bit more difficult because of the limited access due to the convertible top, deck lid and roll bar hoops. Thanks to your instructions of wiggling the old part out after turning it in the proper direction. Like you, I used a magnet to retrieve the back bolt, but to reinstall it, I used a rubber self-adhering tape and started the wrap at just below the bolt flange, then wound the tape up over the socket an onto the extension. It held the bolt nicely in the socket, but was easy to separate after tightening. I didn't have any super glue on hand (the Happy Time method!) but didn't want to take any chance of dropping that bolt into the dark engine recesses. Thanks again Ian, for the great "how to."
Thanks for the tips, Ken. Glad you found the video helpful.
Yep, just picked up my 2009, I've put 3500 on it and have seen the intermittent white smoke at startup. Thanks for breaking this down for me, I am going to do this soon!
I see you were successful. Congrats!
I just completed it. It was a fight like you said, but I won. Took a couple minutes over 3 hours. The shop was charging 3 hours + part for $860. I bought the part from Pelican for $120! The best part is I got to get a good look at the engine!
Thanks for your encouraging video!
Congrats, Bill! Glad it all worked out and you no longer smoke out the neighborhood on startup!
@@IanKarr I still get smoke sometimes on a cold start, but reading the forums some say its due to the flat six design. I wonder if its that or oil already in the intake.. thoughts?
Was very very helpful for me today. Thanks.
Thanks for watching!
Great video. Helped me out quite a bit
Thanks!
Great video!
Thanks Tony. Hope it helps the greater good!
I did it yeah!! Like you said the hardest part is juggling the old separator out and new one in what a game ! But it does come just be patient, a magnet stick is a good idea like you said not to lose the rear bolt , a hot tip putting the rear bolt in is to lightly super glue the bolt in the socket so you don’t lose it as the rear bolt is very tricky and keeps falling out socket ... the glue holds it just enough then easy break after done worked perfectly... the boxster access is a bit more difficult than the cayman but basically the same .... next job coolant level sensor !
Congrats! Glad I could help! Great tip about the super glue...
Thanks for the great video
Glad you found it helpful
Good video , will keep this in mind , doesn’t look a too difficult job to do yourself, I’ve got a 3.4 boxster 987.2 dfi engine , I suppose it’s basically the same ...
As a DIY job, I put it at about a 4 (with changing a tire a 1 and rebuilding an engine at a 10). Not sure about the differences between the 2.9 and 3.4...but should be easy to see if the part cross-references.
Thank you!
you're welcome!
Cheers for that
cheers!
Great video. One question, can you check the membrane without damaging the AOS? I had it changed about 4 months ago and was getting a lot less smoke at start-up, but now it seems to be back again (although not quite as much and quite as often) and a lot of vacuum at the oil filling cap with engine running, which make me believe that I'm having an issue again with the AOS. But would like to check the state of the diaphragm before changing it again, just to make sure there's nothing else going wrong. Thanks!
Thanks for watching. Not sure how to check the membrane. Did you recently do an oil change? Sometimes overfilling creates the same symptoms as a bad AOS
@@IanKarr Nope, oil change was done 5 months ago and I seem to have no oil consumption. It's strange, I haven't had any smoke on cold start-up for the last 3 cold starts, even though the car sit for 4-5 days.
@@west1785 Could just be where the engine stops spinning after shutoff. Some spots pool oil more than others?
Great video, Ian. Question, was there any code or check engine light? My 2010 Cayman smokes when cold and goes away a few minutes later. Could this be AOS? Thanks
No check engine light. If you're having smoke on cold startup which goes away, it might be AOS-related. What year is your car and how many miles?
2010. Only 29k miles
Do you happen to know if the Motorsport AOS version (987 107 926 00) is a direct fit to the 987.2? The only thing i can find when researching is people installing on 986s and 987.1s
Hi Jesus. Sorry...Im not sure. I used an OEM Porsche part. I do know that the 987.1 requires a different part.
@@IanKarr No worries, i appreciate the response and awesome video!
Overall good vid..but i wish u would have shown the complete step by step process instead of jump cutting to certain parts being completed.
Thanks
There is NO need to use power tools to remove engine cover since it's just a cover. Power tools can strip those bolts and you'll eventually need to replace those bolts. I was able to take off the engine cover with a Torx screwdriver.
You right. Lots of ways to approach the task. I just prefer using my power driver. Using low speed and caution I have never stripped a bolt
notices a puff of smoke for the first time today.. had started up and backed it out of my garage, turned it off and left it on the driveway (slight incline upward). when I went to start it again about an hour later and got a puff of white smoke.. Is that indicative of a AOS going bad? or should I just keep driving it until it happens consistently?
How old is your car? Doesn't sound like a problem if that was the first time. Just keep an eye on it...
@@IanKarr 2010 987.2 Base, Thanks, I'll just watch it to make sure its not a regular issue.
@@georgelouie5330 I have read that every 6 years is a good rule of thumb or 50K miles whichever comes first. I'm doing mine soon because of a puff of smoke. I'm at 52k but a 2009 and I have no records of it ever being replaced by the first owner. I have a big trip planned soon as well.
@@darrellsheldon1394
Yeah I'm coming up on 50k miles and every now and then on startup I see a small plume of smoke. I think it's time to consider an AOS replacement.
One Q how long did it take you👍👍
Figure 4-6 hours start to finish if you've never done it before. Half that the second time ;).
Is yours a 2.9 or a 3.4?
Slowbaru it’s a 2.9
what oils do you use ?
What the factory recommended...Mobile 1 synthetic
You still need a catch can. The OEM AOS still sucks.
I've been able to get by without a catch can, but yes...the design could be better ;)
