White billowing smoke?

[venturawildes]

The past two days a large cloud of white smoke has come out of the exhaust when I start my 2002 996 up in the early morning. We live in Ventura and it has been a bit chilly at night. It had done this a few times in the past, but I attributed it to water in the exhaust from rain or the sprinklers. No sickly sweet smell of antifreeze, antifreeze isn't losing level, no water in oil.

Any idea what's going on?

with the latest weather (cold and damp) my hopeful response is that as water condensates in the exhaust and cats its blown out as you start it up as water vapor. If it goes away quickly, it would lend more creditability to my suggestion. crossing the fingers.

Yeah I'm thinking so also, however it seems it may be AOS also. Great news, I was thinking intermix issue. I love this car. 75K on it, bought it with 40K. My little schnitzle runs just fine.

+1 AOS..

I just replaced my AOS. One of the symptoms was a large cloud of white smoke at startup that lasted about 3-4 seconds each time. The white smoke occurred only about 4 times over a 2 month period, but I started to notice a little puff of blue smoke more regularly at startup. So +1 on the AOS too.
