Major white smoke out of pipes

[woodywoodpecker]

Hi guys an gals, I did a search on smoke and came up with alot of people seeing smoke on startup.

My car 01 Boxter S 45k, recently ( 1 month ago) did the white smoke on startup after sitting for 5 days pretty bad. Then mornings after nothing really. This morning it smoked medium to light. On way home ( 18 miles into a 20 mile trip) it smoked so bad you couldnt see behind you.

I pulled over. The exhaust tips has what appears to be oil in them smoking. It smells bad. A kid stopped had an opinion.

First a note : got the oil changed in it two weeks ago mobil one. After the first initial smoke issue one month ago

The kid and I checked the oil and it appears to be overfull, its above the lines in the dipstick. We didnt observe any water in the oil, it looked clean no white. The car runs good, the water temp light was blinking but never went above 190. The dipstick when pulled was smoking.The oil cap when twisted off did not smoke.

He thought maybe it was burning oil from being overfull but the car has been driven 3-400 miles since its change. Maybe a seal?

The bad part is its 9pm here and we leave tommorrow very early for the east coast where we are getting married.So its going to sit for 10 days. I will be monitoring this post while there, I have easy internet access.

Should I drain the oil a bit? And then bring to a shop?

I know it should go in but im looking for solutions.

I have been told it might be the oil air seperator. If so does anyone know what the procedure is to fix this, meaning. I have a shop in my small town that can work on it but cant communicate with the computer. So all he can do is see if the AOS has oil in it etc. Whatever the tell tales are I guess.

Also should it be towed, again it ran fine for two miles to my house and the shop is 2 miles away.

Thanks you

Thanks

The AOS is the culprit no doubt about that, do a search for the replacing procedure, it is discussed manny times. Oh and congrats with your wedding :cheers:

I have been told it might be the oil air separator. If so does anyone know what the procedure is to fix this, meaning.

If you can't find anything here the Pelican Parts tech site of Porsche Pete's Boxster Board will have how to's with detailed instructions and pictures. It's not a complicated R & R but access is tight at times. Good news is the replacement part has been improved since your model year end is less likely to fail in the same way the older ones did. To be on the safe side I wouldn't drive the car anymore until you've isolated and fixed the problem. Good luck and I hope the OAS turns out to be the problem.

Thanks, I did find a link on a how to with pics to replace this part. This is a very helpful forum. I have only used babblers.

Other than billows of white smoke coming from the talepipe, the telltale sign is oil in the intake after the throttle body.

Also note that this is posted in the wrong forum. You want the 986 forum.

OK, I had the AOS replaced. I expected there to be smoke till the oil burned off. I took it for a ride for 50 miles yesterday at speeds between 30-70. It was cool out. Had a little smoke. Then on way back I put it in second drove it up to 6k rpms then shifted into third big smoke came out for 3 seconds then stopped.I did that one more time and more smoke for 3 seconds, then tried again twice an none.

Temperature gauge remained normal but the red was blinking on the gauge. Only half the time though. I did make a mistake two weeks and again last night, I filled the coolant once two weeks ago with 100% antifreeze no water mix. Then after picking up car it was low again and t was some congealing on the top looking like mustard in color and texture. I filled it again 100% antifreeze. Then this morning it was very low. I understand it needs to be mixed was wondering would this cause it to burn it much quicker or the white smoke. When driving yesterday at times we did smell antifreeze.

Better check the oil to see if the coolant is there. Could be a blown head gasket.

Sorry to be the bearer of the bad news. :(

You didn't say how much antifreeze you added. If you only topped it off, there is no problem with adding 100% antifreeze. It mixes with the antifreeze already in your cooling system pretty quickly as it travels through the system.

Remove the air intake tube that leads to the throttle body and see if you have any residual oil remaining there, as well as on the lower part of the throttle body opening. You stated that you had someone else replace the AOS, so I guess it's possible that they did not clean out the oil that may have built up in those areas from your bad AOS.

Good luck!
