I think its normal. We had a freak storm last week in atlanta. Smoke came and left with the snow.

 

Looks fine to me, just cold air temperature.

 

Yea that's definitely not smoke. Condensation ftw. Don't get scared.

 

HAHA!! I thought i was looking at my car! Yea it pours out when warming up...thats why i was shocked when i passed emissions.

Ok here is an update! I ran the car with the radiator cap open and no bubbles. So im guessing im safe with the Head gasket but will still do a compression test. Also like i said i know its cold, BUT i bought this car from an auction not knowing the driver of this car. It is a very good possibility that it was a KID raping this car every red light. I just wanna be cautious to prevent future problems But i thank all for comments ( By the way i tried the closed garage thing for 10 min, oh yea baby! ) I feel happy now)

 

Bro your fine Dont listen to the retards on here please do not go through the trouble of compression testing your car when its condensation. Take it from someone that knows what their talking about.

 

Personally, I dont think theres anything to worry about. With that said, the easiest way to tell is by smelling it. If it smells sweet, its coolant burning since its white smoke. If it just smells like gas (rich), youre fine.

 

mines smokes this bad but its winter and like 20 degrees here right now.

 

In the engine, gasoline and oxygen are burned to form carbon dioxide and water. Therefore, much of what is coming out of the exhaust pipe is water vapor. Combine hot water vapor and frigid air and get a big condensation cloud.

Here in Nebraska, where we are having a little ice age (was that a Mammoth?), calling this smoke would get a chuckle out of any motorist.

 

I endorse this message. For the love of all things holy, it's ****ing cold outside. End of story. It's not smoke. Put your face in the exhaust, smell it! Does it smell like smoke? A large Pizza from Domino's says it doesn't!

 

dude no its not because its cold outside your engine is totally blown

does this look odd to you? No one tore apart this airplane because some "smoke" was coming out of the engine while it was flying.

Cold Air + Warm exhaust = condensation.

 

Ha ha i wouldnt get on that plane lol

 

You people are throwing the term condensation around like it's some magical phenomenon that occurs when it cold. Its a chemical reaction that's dependent on temperature and moisture...e.g. water. When you breathe out in winter and you see ur breath, its actually the moisture (water) from the heated expired air from the lungs. The air expired from the lungs has high water content and thus, when it meets the colder than body temp air, it "condenses" into a visible vapor (cold temperature causes molecules to slow and become a more dense mixture...same reason why an engine likes cooler air...more dense air has a higher concentration of oxygen for better combustion). This is also the same concept as your cold beer on a hot day. The warm ambient air contacts the cool surface of the glass and moisture in the air becomes condensed into tiny water droplets. So with that explanation in mind, apply it to your car's exhaust. We obviously have the change in temperature from warm exhaust air to cold air outside. So where's the moisture? It could be coming from your car (water from your coolant mixture that is inside the exhaust...bad news), or the moisture is in the ambient air and is becoming condensed as the hot exhaust air comes out, which is dependent on water content in the air (humidity).

So which is it? Go check your coolant level in ur radiator once the car is completely cooled down. If your low, you may be leaking some coolant into the exhaust. The fact that its a new car puts some unknown variables in there. You would need a reference that the coolant was at a higher level and now its lower due to the loss. Chances are, if when you open the rad cap and you see no fluid, you have a leak. If you are leaking coolant into ur exhaust tract it becomes very obvious in a WOT pull, because the exhaust get really hot, and the increase in rpm causes pumps to push harder and increase pressure, thus increasing flow to the leak point causing water to pour out, and you see something like that picture of the jet above .

Here is a video of my car running a few weeks ago. I live in Vermont, where it is obviously freezing, but with moderate humidity (40-50%).

So what's different between my car and yours? My car has no coolant leaks for sure so we can rule that out. When this video was shot it was not snowing. By definition, in order for snow to form, there needs to be excess vapor (humidity) in the air. Warmer, vapor rich air contacts a colder area of air and the vapor precipitates as snow. So in ur case, while it was snowing, the vapor content in the air has risen.

My conclusion...could go either way. The most difinitive way to solve this is to look at your coolant level. If you are losing coolant, there's ur problem right there...if not, you're most likely ok....This was much more lengthy than I had initially planned , may have gone a little overboard with the chemistry lesson...hopefully this helps out!!! Good luck
