Is it all the time or just sometimes?

Does it smell like raw fuel or coolant? If it does it all the time it's one of those. Did you do any recent work to it?

Does your car idle weird, if so you might wana do a compression test on all 6 cylinders... If its white smoke its most likely coolant leaking into your cylinders which means bad head gasket....

you sure do drive fast lol

my car does that every once in a while too. sometimes from under the hood/behind the motor, and sometimes from under the car, but close to the front. hasn't done it from under the car since i got my new exhaust on though. i've been wondering what it is. it usually happens after driving on the interstate.

If it has been sitting for a while things are going to dry up and fluid will begin to sit. After restarting it and driving it... sometimes faster than other times... you are going to get everything flowing again. Seals and metal are going to swell and contract from the heating and cooling. Watch fluid levels closely for a week as you drive it constantly and if the smoke goes away and levels are okay then good. If not then you are going to have to dive in and figure out where you are leaking from. My guess is most likely the headgasket.
