'99 Box: Replaced AOS still looks like a fog machine! - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Ok, I did spend about an hour and a half searching this forum to try to find an answer, but couldn't find anything that matched exactly what mine is doing...

I just bought the car (always wanted one) with smoke (LOTS OF SMOKE) comming from the exhaust. There was no knocking, ticking, water in the oil, milky oil ect. So, I thought it would be an easy fix with the air oil separator! I just changed it out today and it is still doing the same thing as it did before. It may be idleing and reving a little better. I let it run for about 15 minutes and there is no change and it does not overheat during the time either. I would shut it down for a few mins and then let it run again for several minutes... the smoke never improved!

I also unplugged one end of the j-tube while it was running and it died. So then I plugged up the j-tube and cranked it back up...still blowing the smoke! What else could this be? I'm at a loss. I sure thought it was the AOS! The new AOS that came in did look a little different. Mine (at the top) was more horizontal and the new one was more vertical. I assumed this was only an update? Please help!

Also have a couple more issues I'm not sure of. 1) I cannot get the windows to work. 2) The radio stays on all the time. I have to manually turn it off..even with the key out! 3) The MPH, and odo and the gear indicator (automatic trans) stay lit all the time as well.

Oh, the car only has 79k miles on it....

Thats seems like a very bizarre issue you are having. I would have also guessed that the smoke is due to the AOS. Do you have a CEL? As for your electric problems... Does the button click for the windows? Do you have the becker radio (stock)? Maybe your battery is no good? I can't see how but try to unplug your car for 10 minutes and then reconnect battery. I'm doubtful but hey it's worth a shot.

Here is a little update:

Oil level is fine (1/2 way up marker)
Coolant level is fine
Tried driving down the road, made about 6 city blocks, way too much smoke to continue, turned around, came back to the house.
No Check Engine Light...

Very confused about what to do next. I'm about 2 hours from a porsche dealer and really don't want to go that route!

For the electrics:

It acts like it this a key is still in the ignition. When you open the door with the key out, it still dings.
I cannot get the remote to arm (may need to re-learn the key?)
It's a stock radio.
You can hear a faint click when you push the window down button (they are already down). You hear nothing when you try to make them come up. I've tried with the top up and down.
The top open warning light is on, even with it's closed. I heard there is a sensor for this?

It's possible that you did fix the problem by swapping the AOS, but that there is still a decent bit of oil in the exhaust that needs to burn off.

How long should this take to clear all the old oil out? Is there anything I can do to speed this up? I am not very good at being a Porsche mechanic yet, so please help me out with the details if you know anything!

The leading suspect in many electrical issues is the ignition switch.

I'd try and drain the oil and then refill with new. Also clean out maf and throttle body.. When I changed mine out took about 20 mons of running to clearnout smoke but u might have more oil in there..

The intake as well as the cats and muffler will have residual oil inside them.. It'll take a few days to get that all out of the systems..

cliptfc · 01-28-2010, 02:25 PM

ok! I think the smoke is fixed! I think it just had a ton of residual oil left in there! It took about 35 miles of driving 60mph, but no more smoke! It was the AOS all along!

Also, I replaced the ignition switch but it still acted like a key in, even after it was removed. Found out the actual key socket was extremely dirty and not popping back out like it should. I cleaned with brake cleaner, then oiled it, now it works fine!

But the windows.. ahh the windows.. they still won't roll back up! I'm going to post a new topic on this.. maybe someone knows?
