Default white smoke??

Today I turned my car on and very very thick white smoke began to come out of the exhaust, I let it idle for a few min and it kept coming out. The smoke was extremely thick and covered the first floor of the parking garage I was in. I left it off for a couple of hours tried it again and its fine. I had just changed the oil a few hours earlier. Anyone know what this could have been? By the way its an 06 sti w/ 7k miles, w/ a tbe.

White smoke is usually from burning coolant eg blown head gasket. But the recent oil change and the car being fine later makes me think maybe you just spilled some oil on the exhaust. Are you sure the smoke was actually coming OUT of the exhaust? Was it really white or more blue-grey?

Was it unusually cold there? Maybe it was just condensation.

If you use car video game logic...

white smoke is okay... your car still has a few hits left...

but BLACK smoke.. uh oh... Ditch the car, its about to explode!!!

and if there's fire under the hood, i don't think you need video games to tell you what that's all about ...

White smoke= Water, or coolant
Blueish white to Blue smoke = Oil
Black smoke (upon acceleration) = Incorrectly burned fuel, AKA carbon.

'extremely thick' sounds like oil smoke. Steam dissappears as it cools.

Did you run it RIGHT after changing oil? Did the engine idle crappy? Any CEL's? Any smells?

I might not be much help, but these details mught help other more knowledgeable folks out.

overfilled the oil?

keep an eye on your coolant/oil levels, i too notice on every car i own that has a tbe much more steam/water vapor and even water dripping out of hte exhaust on a cold start, sometimes "heavy" but not as heavy as oil/coolant burning in the combustion chambers... water is a byproduct of combustion though and old guys will tell you it's a sign of a properly running/good condition engine

If it's smellign sweet it could be a Head gasket...I had thre same issue a while back went driving one night I didn't think much of it wasn't driving hard but hit detonation and exploded 2 plugs and the ceramic damaged my Head gasket...Woke up the next morning and white smoke poured out...Once it got warm and sealed the gasket it went away...But what a pain..
