Have you ever had this problem with your Porsche Cayman, Boxster or 911? White/Bluish smoke on a cold start, and it makes a giant, embarrassing and smelly smokescreen in the driveway or on the street… That was exactly what happened to my 2008 Porsche Cayman. Although this problem seems more common among 986 Boxster and 996 911, some other Porsche sports cars may have the same issue. This, in my case, was caused by a broken AOS (Air Oil Separator). Fortunately, I got it fixed in its early stage of failure, otherwise, it would have been way worse…
Watch today’s video to see if this issue is what you are facing and see if my solution can help you. Good luck!

Great video. Great Presentation. Great explanation. Great editing. Great car! You deserve more subs.
Thank you!
Agreed
Great video with simple explanation and examples! Big thanks!
I have the same problem with my bmw petrol 3 series. All started after bmw did my oil and filter service. So I think its a similar cause. Booked in now to take it back to bmw. This video helped me narrow down my problem. Plus when I lift the oil cap i think i get suction too. Not 100% sure. But it sure makes a funny noise when i do.
Thank you _ I have a 2006 Porsche 997 and the exact thing happens to me EXACTLY - I appreciate you
Thank you buddy, your video help me a lot. I have a 997 Carrera S with the same white smoke problem.
Thank you for this video! I have the same Cayman 987 with identical colour of your car! I was following your videos as the car looked so good 😀 and then found out I have the same whitesmoke problem!! Also, after seing a lot of Cayman videos, it eas you who find out the trunk lid is easier to close if the door is open! Props for that.
Ruby red metallic is such a rare color and it is nice to know someone with the same Cayman. Glad you enjoyed my videos. I will be uploading a tutorial on how to change the rear brake on Porsches very soon. Please stay tuned! Thank you!
Well produced video and very helpful!
Nice job explaining everything! Thank you.
Thank you for watching and commenting!
Thanks dude......great vid.....I appreciate your efforts. Subscribed.......my 986 just started up with white smoke today.......Will try your tests
Thanks man. Just moved to a new place and am trying my best to squeeze out a new video... definitely give it a shot, hope the car can do well soon
Great video my dude helped a lot !!!
Very we'll articulated answers and explanations without all the time consuming unrelated "fluff". I had 2 Porsche's both had this problem.
I did tons of research and never came up with a valid answer, Good job. Also liked your Asian accent!!
Great information and well presented. I own a Boxster S, but have a friend who just purchased a Cayman.
L Alva essentially the same car :)
Great finding!
Excellent video, thank you very much! happy driving!
Thank you!
Hi, great video thanks 👍🏻... question, did you have smoke on every cold start?
I have a 2017 Kia Optima that does the same thing but I need to check the oil opening to see if it does the same thing......and this was by far one of the best presentations....keep up the good work
Thank you very much!
This is what I’ve been looking for. My ford edge was having this issue after they replaced my oil pan. The cap trick is a good test.
Great explanation my 987s Boxster has this problem got worse after last summer I'm in the process of doing it this weekend
Thank you for watching! I hope your car gets better. Comment here to keep us updated!
Good video, thank you.
What an informative vids man. Excellent.
Thanks！
Thx for posting. I have the same problem. Mine blow out 10 times more smoke than what you have shown. I thought it was catalytic converter which is much more money.
Brilliant video. Thanks!
Thank you for commenting!
Well made video!
Great video, well explained and nicely presented. My 997 only smokes very occasionally. If the car is started from cold and then goes on a journey it's perfect. It only seems to smoke if the engine is run for a couple of minutes then shut down, (let say the time it takes to remove the car from the garage to the drive). Jump back to leave and the smoke sometimes appears, after that nothing. stop / start as much as you want and the exhaust is clear. Not sure if this is the same issue but Porsche tell me it's not uncommon for this to happen due to the engine design but I will get this oil separator checked if it gets any worse.
Thank you, and nice comment as well! Let’s hope everything goes well in the future.
Oh man... hopefully you’re right ... I gonna try see something for my C63 AMG 2008
Thank you! BMW X5 edrive 4 cyl , experiencing the same symptom. I will have to replace the whole valve cover due to the pcv integration into the vc.
Awesome video dude 👍
Thank you!
Well done 👍🏻
Thank you!
Good job and well explained...?
Dude you're awesome
Very very good thank you. Jon
Thank you for watching and commenting!
Lots of cars will put out white smoke on cold start due to condensation. But it shouldn't smell like burnt oil. It should stop after about 30 seconds.
I have this on my 987 (07 with 28k miles). Can't wait to see this!
Well now that I've watched it I'm confident the AOS is exactly the issue. Thank you for the video!
I just replaced the thermostat sensor (it was giving me a warning and the gauge would instantly drop to zero then randomly come back up to show normal temp). But it fixed it.
Now I'll take it back in for this... Once I set aside about $425 apparently lol.
What color is your 987?...
The color is Ruby Red Metallic. Quite a rare color today and I strongly recommend that you come check out my new video about the options on my car. You will be able to see its full glory. And thank you for commenting!
@@WhatWeDrive Oh yeah that's a PTS special order color if I'm not mistaken?
You might explain it in your video you suggested. I will watch it now, I'm interested.
Nice 👍🏽
excellent vdo, keep up the good work.
Good job
Nice explanation and also bear in mind by diagnosing the fault yourself correctly and logically you were then not overcharged by the repairer , 3 hours labour is correct so your bill was fair and reasonable , sometimes its easier to just do a bit of overtime on your own job and earn some money to pay the mechanic to do their job
I'm curious if that vacuum condition at the oil fill went away after the repair....
Great result
I had the same problem, had code p1128 and p1130, changed the AOS and the code went away but I still have white smoke on startup with gasoline smell from exhaust. Any idea what can be wrong?
I bought my 06 cayman s less than a week ago no problems at startup until today it was smoking a good amount. It might've been a one time thing because I refuse to believe that it just completely broke in 1 day (it was fine yesterday). I guess time will tell.
A sooty exhaust tip is also an AOS failure sign. Tracking your 987 is harder on an AOS than just street driving, as the high RPMs can cause the diaphragm to tear.
Great tip. I remember 987 having a Motorsport AOS that’s designed for track use so that will probably help those who wish to track it.
@@WhatWeDrive Yeah, those work well but I can buy a dozen+ factory AOSs before it equals the price of one of those. I'll spend $100 on a spare and put the money I save into tires or brakes. YMMV.
If i hear motors sit the piston rings shrink as they cool and allows a slight bit of oil to enter the combustion chamber. so when you start up it burns it out. Totally normal for a horizontally opposed motor. Subaru motors do the same.
My Boxster just whacked out massive smoke like this at cold start, nearly had 7 simultaneous heart attacks
I feel ya
Great Video clip! Sorry for the intrusion, I would appreciate your opinion. Have you tried - Peyvery Phrenic Prevalence (probably on Google)? It is an awesome one off guide for get your original hair color back and look young without the headache. Ive heard some pretty good things about it and my friend Sam after a lifetime of fighting got astronomical success with it.
Even though the AOS was the issue, many times it can be the valve seals going out, which can be cured by adding product every oil change.
Product?
Thanks! Did you check if the vacuum suction was reduced at the oil filler cap after the new separator was fitted ?
Yes, there was still a bit of suction, but not nearly as "sucky" as before
@@WhatWeDrive Thanks. Mine appears good and ok, though I’ll now feel how much suction is at cap and check again if I ever get smoke. Cheers 👍
Hello brother, is the function of this part similar to a PCV valve?
I had the same problem a few months ago, changed the oil separator and the problem disappeared.However after 3 months the same problem has returned..Not sure what is causing the oil separator to fail. Has this happened to anyone else? Can anyone shed more light to permanently resolve this issue?
Great details and video, exact issue I am having, bluish to white smoke on cold start I am having, but have no vacuum found at oil filler cap. Were you consuming oil? I am going change AOS, maybe it will fix my problem.
Huh... actually maybe check if there was any oil on the inside of the intake? My car wasn’t consuming oil though, I think because I caught it early enough.
Is that Pcv value? The smoke is was smile?
So this is what happens with my GTI and I think since they share parts it might be the similar for me
The only thing I'd like to add is that the AOS is a badly designed part and is prone to failure. I'd expect the new AOS to last 3-4 yrs and the smoke will slowly start to return. That was my experience anyhow and I'm assuming that's the reason why owners don't replace them and just suffer the smokey start up.
mine is boxster 987.1 and I also got white smoke at cold start. I replaced AOS myself and no white smoke afterwards. AOS parts only cost around 120USD. If you go to dealer, they charged you service fee around 180USD. The service fee is more costly than the part itself. Unbelievable
Exactly, after all this is just a plastic part at a tricky position
That problem can happen in mercedes engine also?
I just had AOS replaced on my 2009 cayman 2.9l base and 2hrs of sitting after the repair boom still white smoke? Does it take time to burn off old residual oil from failing/failed AOS???
Did you solve your problem?
Might want to inform your vehicle specs as just the base 987 not a 987.2 the AOS is not in the same location, Also With the time spent doing that install it took roughly 2 hours with a pair of extra hands. Im surprised the shop didnt advise to clean the intake or change spark plugs because the broken AOS will let oil bypass to your spark plugs and intake..
They indeed cleaned the intake, they found oil in it
My AOS is not sucking in but its pushing air out.
Is aos the same as a pcv valve
Ok Ok Ok .... guys how can a pcv/ccv/sep not work on first start ? I just can not understand it. Have the same problem + rough idle on cold.
Beautiful colour...do you still have the car?
Not anymore 😢
Good job
I change my AOS but it came back after 2 weeks, any idea why?
Check installation, if everything looks proper then checking with a mechanic is probably a good idea.
Mine literally just did the same thing. I'm wondering if off brands suck and break quick?
Update: apparently your trip distance also matters. If you drove… let’s say… only a mile and shut the car down, leave it for a couple of hours or overnight, you may get smoke again (but nowhere near what I had in this video). Maybe avoid driving extremely short distance if you are doing it.
Hi everyone! My new video is here. I have taken many suggestions and am happy to share my latest review video with you all:
E89 BMW Z4 sDrive 35is review, filmed at Angeles Crest Hwy. th-cam.com/video/HdrrB1-8jfI/w-d-xo.html
Please feel free to check it out and give some support. Thank you! 😉
I don't think that oil cap test really proved anything. You should check if the oil cap is still getting "sucked back in". I bet it is, because like you've been alluding to this entire video, the crank case is connected to the intake manifold with this oil separator in the middle, the intake manifold will produce a vacuum as long as the car is running.
Thank you for the comment. You are right about the vacuum while the car is running. I just discovered that when the AOS failed, the vacuum was significantly stronger. I think there is a difference. The mechanic who worked on it also told me about this so I am happy that you brought it up.
I replaced oil separator still white smoke
Change the AOS. Can be DIY. Not end of the world. Got it.
Thank you very much!! ... little story for you...
Exactly the same thing happens on my 07’ Cayman.. not every time on cold start, but occasionally.
There are no dealers nearby me, however.
I have a guy who is very good, mind you but sometimes I feel like he tells me what I want to hear.
“Oh that’s normal ... all Porsche’s do that”.. Bullshit! ..I don’t buy that! .. I even mentioned the oil/air seperator and was told no.
Going to a dealer is not an option for me (many miles from me, and I’d be basically robbed blind if I went there)
Anyways... speaking of Porsche in general .. nice car... BUT! Later year models? .. like mine? A ticking time omg, money pit! ... I can’t wait to dump it... piece of junk! ... fix $800 fix $800 fix$800 fix $800 fix $800 ... ever own a boat? ... same thing.
Mine the same I just bought the cayman
WOW, only $100 per hour? Around the San Francisco Bay Area it is $180+ p/h
Not to mention CA has a much higher tax rate than where we are
Blue Smoke...
Dose your car consume oil??
Not really.
@@WhatWeDrive thanks for a quick response
3 hours is a long time to fit one of those....🤔
Oh don’t be surprised especially that this little thing is so close to tubes. I have friends who broke one of the tubes nearby. Though not hard to fix, but then it will take more hours before the three hours 😉
Let alone they kept your car for 2 days for 3 hours of work. Unacceptable
Didn’t work for me ..still white smoke at start up
Time to see a mechanic 👨🔧
Apparently your meant to wipe the oil out of the intake..plenum ..
you mean pcv?
Nope, definitely not. The AOS functions differently than a positive crankcase ventilation valve
Lucky it is not bore scoring ah nevermind its not an s 2.7 engines. Supposedly dont suffer
10 minutes to figure out it's the AOS?
He want you to waste your 10mins
Nice. Tk you. ? I’m. Goin to fix. Know my car
4-6 oz of marvel mistery oil every oil change will keep that from happening
Do you have a Porsche? This is a common problem. MMI won't prevent it or repair it.
Anyone that says its because its a flat engine has no idea what they are talking about
This isn’t something you would want to leave. If you get too much oil into your cats they will prematurely degrade
Absolutely agree! This is a small issue that can turn into a disaster,
Porsche..................never again!!!!!
Why?
@@ambitionsskyyyy AOS and IMSB problems. The IMSB will destroy the engine. They are lovely cars but money pits.
Same with BMW M3, I own one that i took delivery of in Munich. German sports car are unreliable POS. Reliability is a second connsideration to german engineers.
