How to Fix White Smoke on the Porsche Boxster 986
Vložit

- The air oil separator or AOS is a common failure part that leads to white smoke coming out of the exhaust when you first start your car. Fortunately, it's a relatively easy and cheap repair.
In addition to the white smoke, symptoms may include a check engine light with codes P1128 and P1130. This is how I solved the problem on my 2000 Porsche Boxster S. For my Boxster, this was part number 99610702304. - Auta a dopravní prostředky
Ben, these old videos are pure gold. Thank you.
5 year old video gave me some help today. Gotta love CZcams and your submission. Thanks!
SMOOOOOOOKE on the BOXSTER and fire in the sky
it just came to me!
Thank you very much for the video. I did it myself (took between 1h15 and 1h30). It saved me some cash... And indeed taking the tire off is the way to go (as James mentioned).
Thanks for video. Great tips.I am doing mine in a couple weeks.
Well done and quite helpful. Thanks for the assistance. God bless....
unbelievable that porsche wanted to charge me 1500 and mentoined me totally different problem yesterday, now i am ordering from ebay genuine part £105 and most probably i can do it myself :) you are the god
Well done video, Sir! Thanks for the info...
Great! Thanks for this informative video. Just cleaned the throttle body, lot of oil in there! Next job.
For me it’s the oil separator but I get the code P1141 or P1140 which leaves me dumbfounded.
Love your video! Really helped
It's my turn to do this job this spring, I have the special clamp for the bottom hose it's like clamp with an extension cable. Thanks for your help!!
Happy to help. Since doing this video, I've found it's a little easier to access the underside of the AOS if you remove the right rear wheel.
Your videos are most useful. thank you!
Very welcome, Rob! Glad I could help!
Beautiful work
thank you, i will definitely check it in the morning again ,i felt that the tube that goes from the oil separator to the truttle body wasn't so tight ,but didn't tought it might be it
That could definitely be it. It takes some working to get it back in place, and when you finally do you'll hear and feel it snap into place. Let me know how it goes!
This is a one hour job with the car on a lift or stands. You need to remove the transmission skid plate for access to the AOS from underneath. You can get to the mounting bolts, crankcase hose, and bottom vent hose much easier than from the top. Doing the whole job from the top multiplies the time, scratches to the paint, and lacerations by four.
nicely explained. thanks
thank you so much again
Putting it back together, a little WD40 on the part that slips into the block under the bolts will help. Same with the bellows. Thanks for posting your video, It will help, I hope. This is supposed to be easy, I guess. Also some other videos suggest using a screw clamp instead of a spring clamp, might make it easier next time.
Thank you i will go over the fuel lines and thw fuel pump, the air lines i think i went by all of them
It sure seems odd. Let me know what you find... and feel free to message me on fb (facebook.com/Burnerscars) as that's a little easier for conversations. Good luck!
Did that orange part sit flush against the engine (no orange showing) or did you have a bit of the orange showing? I am having same exact problem that you were having with that orange part and its frustrating. I have it all bolted up but I havent connected the hoses because of the slight orange im seeing
Burner, Thank you for the explication and the great video. My Porsche dealer simply said that if the white smoke only occurs at startup there is no real issue. Is this just a precursor to having to replace the oil air seperator or can i trust that is not a "big deal"??? Cheers. David
It could be normal--particularly if it's cold or the car's been sitting for a few days. If it's not a lot of smoke and you don't have any of the other symptoms, I wouldn't worry. When they go bad, they can create A LOT of smoke. Of course if you notice it getting worse, well, definitely the AOS.
Thank for the video...saw it AFTER I had the dealer$hip do it for me. Question... after driving 10 or so miles home after work, I see smoke coming from the mid section when waiting at a red light. After another short trip he me, it's gone. Am I burning something up? Transmission? Oil? Not a definite white or black smoke. Just kind of steamy. Thanks!
Now you'll be ready the next time it goes out! As for the smoke, I have two thoughts: 1) has it only happened one time? If so, it might just be that a little oil spilled during replacement process and just burned off. If that's the case, then it's nothing to worry about. 2) Could it be an unrelated coolant leak? "Kind of steamy" makes me think coolant. If you haven't done so already, you can check the coolant level to make sure it's not low.
i checked the hose that going out of the oil separator, disconnected them and conected from new bit no success to start the engine
Hi ,first of all want to thank on you videos they are very helpful, I have 2001 Porsche Boxster s wanted to ask is there any differents between the original oil separator and the after market once,thank you
Thank you, sir! As I recall, the only after market oil separator is the URO one, right? I haven't personally used it, but I know people who have. It seems to work well, but based my experience with URO parts generally, I find they are a little lower quality. I think you're good to use the URO, as long as you're prepared to replace it a little sooner than the Porsche AOS. It's pretty easy to tell when they go bad, so you'll be able to catch it and swap it out if the URO AOS dies an early death.
Thank you
Awesome video.. Just changed mine! How long did it take after you changed out the AOS for the smoke to finally subside?
hey burner found a quick easy way..start by taking off tire..get long extension and swivel for 10mm..take two bolts out first then all hoses come off easy..took 45 min
Great tip! I'll try this the next time I do the job.
wish me luck Im going in today if that manchester rain holds off...got no garage :-/...any other tools necessary?
Awesome video, thanks for posting. Please confirm the size of pretensioned clamp.
35mm, I believe. For my Boxster the part number was 99951263000
had a tough time finding the pretensioned clamp specifically online, ordered through dealership. Both the clamp and separator about $150. Thanks again!
Thank you for video! Is it necessary to drain the oil before changing the oil separator?
hi ,i did change the oil separator to origin variation which bought from ebay amd from some resom my car didn't start since then,i do have a crank but it's doesn't start
tried to put some starter fluid and it started just for a second and turns of right away
checked the fluid pump relay and it looks working fine but no success to start the car,
any idea what it can be the reason
thanks
I've got a pretty good idea that you've got a vacuum leak. Check all the hoses you removed. Are they all back on the way they came off? are all the connections secure?
What part do you recommend OEM or other?
"You are fumbling around blind in the nether regions of you car." Yep, been there. I know my cars a bit too intimately. Usually at that point I am letting loose some choice curse words.
yes i did checked them all ,when i spay start fluid to the air filter the car doed start for a moment and turns off again so o need its something with the fuel not sure yet
It seems incredibly unlikely that you would have an unrelated fuel problem at the exact time you replace the oil separator, but it's possible. Realize, however, that the symptoms would be the same for a vacuum leak and a fuel problem. If you have a vacuum leak, air enters the engine downstream from the MAF. The engine doesn't expect this extra air, and so runs lean. When you spray starter fluid, it compensates for this and starts momentarily... at least that's one possible scenario. These things can be hard to troubleshoot, but it might be worth another check through the area where you've been working to make sure nothing got bumped / disconnected / damaged. Good luck! Let me know what you find.
Hi brotha ..I had my mechanic change this part but now it has some type of oil leak I think ..I found that in my garage ...pls advise
Vladimir Marley might b a rear main seal.
Thanx
Should i wait for mine to fail...or should i swap it out as a preventative measure..?
As long as you watch for the warning signs you'll probably catch it early. If you don't catch it early it can foul o2 sensors and such, but if you're paying attention, you'll probably notice it long before that happens.
My wife's 2006 boxster purchased new has smoked sometimes on startup since new.
Did you end up changing it? How was it? Im about to start it :-)
I cleaned mine with 99% iso propanol then WD40 and blew it with air. Hasn't smoked for 6 months now
PS thanks for the video!!
hi i tried to take out the hoses that goes to the oil separator and put the back in till they stap on but still no success to start the car ,so i guess its a different reason that the car crank but not start cant understand why
Weird... it seems unlikely you have an unrelated problem at the exact same time you replace the oil separator... You checked all the hoses? even the ones that are hidden underneath?
I pulled off hose while car was ticking over once..a massive implosion sound car cut off...scary moment....I think maybe be one of the hoses wasnt seating properly?....what actually happened?...3years ago?
Oh by the way mine has the old style separator so I bought the top hose so it would reach.
Hey Burner, where did you buy the new part and the clamp? Was it OEM or aftermarket? Thank you!
I had a bad cam sensor..so I replaced it..but now car runs but no throttle at all just idles then dies again
totally missed this comment when you posted it. Did you get your car sorted?
The aos was toast on the cheap 996 i bought a while ago. Also try not to drive with a bad some for a while since it can burn up the cats.
How did you the the hood open so far? Lol
Did you scroll under the vehicle to get the two bots out ? at video 5:15 I did not see this part in the video. Also could you tell me the tools used to take out the old one and put the new one. I was wondering if you have to use jack stand to do this job?
+RK RK I did the entire job from the top of the engine. It's tough and cramped to reach down in there, but I think it would be nearly impossible from the bottom. There are a couple bolts down there... metric sizes and a hose clamp. Feel around to remove each.
Thank you for quick response. I was wondering where did you buy the part(s) and the approx. time took to replace it. Some websites are offering aos + a hose (i think it is pelican parts). And other places OEM part running about $125.00
***** I definitely bought the OEM part. I think there's a cheap URO part running around, but I don't trust it. Bought it online from Pelican parts or somewhere similar. I think the whole job took under an hour. The only difficult part is reaching in to unbolt the bottom of the AOS.
Dammmmn you look like Sebastian Vettel
There are better videos for this project. An "E" for effort.
Let's see your video ...camera access is extremely difficult and the created dialogues really help.
What a g
Well done and quite helpful. Thanks for the assistance. God bless....
