are you stock? if it was just a little bit when you started the car, dont' worry about it. If it's excessive, and thick, that's different... but a little puff on a cold start is nothing to worry about

im all stock didnt notice when i started it noticed when i built up boost

Your car is racist...why does it have to shoot out white smoke? Why can't it be black smoke? Thats descrimination!

D4u2s0t

it's not discrimination!! the car just knows that white smoke is better than black smoke!

i think thats normal. my G5 did that the other day. i hit the gas and my friend was behind me and he said he saw white some come out the muffler when i hit the gas. nothing to worry about i think.

But everyone knows that black smoke is thicker than white smoke LOL

haha... can't argue that!!

Technically "white" smoke is blue as far as actual smoke goes. But if its white then its moisture

At about 7100 miles, I had to have the head replaced. There was a defect that in a water jacket by the seam. When it was originally blasted to smooth the casting seam, the person or machine got a little thin. Keep an eye on your coolant level. If it starts to go down, take it to a dealer.

Were you in an "alcohol fog" and didn't really see any white smoke to begin with...

blown07

ok... here goes - again.

white smoke, early startup, cold day = condensation in exhaust evaporating. you're actually seeing steam.

blue(ish) smoke, anytime = lean or indesperate need of an oil change!!! usually accompanied by knock followed by BOOM or *SIEZE*

black smoke, anytime = rich, you're ok but losing power like mad - get tuned.

bigd2114

with the black smoke one....tune or smaller pully

keep an eye on it.. if it speratic then whatever but if it is a continuin problem.. check your head gaskets.. you have a coolant leak somewhere then

bc3tech

yeah i s'pose that'd do it to... bottom line is you're rich and need more air

D4u2s0t

yea... i'm thinking it's just moisture.... like i said earlier, as long as it's not all the time, or extremely thick, i wouldn't worry about it so much... my car always smokes when it's cold out untill it's all the way warmed up... don't forget now that it's cold, your pipes are going from 20degrees to 200 degrees in a few minutes... when it starts warming up, the pipe collects condensation, and when it gets fully warmed it starts evaporating.... /end science class

GOT BOOST?

Check your flux capacitor !!! Don't worry it is nothing just getting cold

i know about moistier but this was enough that i would call it a large amount any time i hit the throttle heavy it done it and it lasted for several blocks not just on craking and initial rev i have built a lot of hot rods in my day and i know all the basics i thought it my be where it was cold and it sent fuel to accomadate for the air sent by sc and couldnt burn the fuel or what i havent delt a lot with fi engines as far as sc and turbo so im not sure what is a problem and what isnt but i do respect all honest answers but i dont need to be talked to like a child please i understand the whole cold start up and moistier thing but this was enough to be a noticable cloud around the car behind me several bloks from where i started thanks

blown07

my last remark was left in reply to the one that begins with here goes again im not trying to offend but i understand the basics

biohazard

head gasket maybe.... if your burning coolent it will be white... would make sence that it happens whenever u boost, probably a small coolent leak into the cylender

bc3tech

the reason i said that is because i know for a fact this has been brought up on this forum before. searching ftw.
