possible blown head gasket.
I don't get white smoke from my exhaust! is it from yours?
If it is just after you start your car it is normal.
All cars blow white smoke when they are cold especially on a cold morning .Worst case scenario if it blows excessive white smoke all the time is a blown head gasket
Most cars have a little white smoke on start-up, but a consistent plume of white hot smoke is caused by antifreeze leaking into your combustion chamber and being expelled as steam. This is a bad thing.
Burning of oil in cars can contribute to blue smoke from exhaust. However, it is also possible for a car to make blue smoke if a turbocharger is broken or experiencing an oil leak.
Condensation
running rich (too much fuel)
Snow itself is always white. It can change color after it is on the ground. The main reason for this is the exhaust from cars and trucks turns it grey to black, depending how near it is to traffic.
The answer is smoke. Smoke is often caused by cars this is by hbw9999
yes most gasoline/ petrol burning cars will have more water vapor in a cold start situation
An Rx7 is a model of a car that Mazda makes. All cars can smoke lightly through the exhaust system. If the smoke that is coming out becomes excessive or black consult a mechanic.
The same reason a home fireplace needs a chimney. Cars burn fuel and air. The byproduct of this is exhaust gas. The exhaust gas needs to be expelled somewhere so it is piped out under the vehicle to the back where nobody will be breathing it.
blown head gasket. the easiest way to tell is to open the radiator cap while the cars running BUT BE CAREFUL! if theres antifreeze in there it will spray and burn you! but if you have a blown head gasket when you open the throttle the same white smoke will blow out of the radiator cap. white smoke is a sign of a blown head gasket though.
Disadvantages are, because of cars giving off exhaust smoke. Advantages are, cellphones in case of emergencies.
