on days that it rains, or when it's cold i sometimes get white smoke that i can see out of the back. i was driving home from work last night, and my friend was behind me and said a big cloud of white smoke came out of my exhaust when i gunned it, but from only one side. my sisters boyfriend said a long time ago it could be an 02 sensor going bad, but i REALLY don't trust his opinion. is something clogged do you guys think?

i know white smoke = coolant generally speaking, but it only happens on certain days, and i don't know if it's normal or not for the car to smoke. i do have the dual exhaust btw.

that's just the way our exhaust's are routed. almost all the flow ends up coming out of the driver's side.

white smoke is coolant and or moisture burning i belive so if its when its cold or rainy that could be it.

our cars aren't TRUE dual exhaust... it's a single exhaust, Y'd into a dual near the rear of the car. So at idle, and sometimes during driving, most of the exhaust comes out the drivers side.

As for a big puff of smoke... if your car had been idling for a while before hand, or if you hadn't driven it in a while, it will puff from moisture, if your valve stem seals are going bad (to check if this is teh case, drive the car, park it, let it idle for a little while, then give it gas, if it smokes, it's more than likely your VSS).

Well the stock system doesn't Y towards the rear. It runs into the drivers side muffler, and then back out the passenger side muffler, at least on the TT's, I assume NA's are the same way.

Also, VSS smoke will be tinted blue.

Yes, but 99% of people call it white not knowing any better.

well that cleared up a lot. thanks guys!! yes, i did let my car idle a bit before i started driving. i started it and was running through my mp3 player to find music. it's not a repetative problem, so i dont think its VSS.
