this will depend on whether the white smoke is just when first starting or after engine warms up. if it only occurs when weather is cold and engine is cold. it could be just burning off condensation which is normal.
if it occurs when engine is warmed up:
white smoke = coolant being burned in cylinder.
cause = bad head gasket, warped head, cracked block, leaking intake manifold gasket, cracked intake manifold.
also check for coolant in oil.
the first step would be to determine which "cause" you have.
pressurizing the cooling system will help to narrow down the cause.
cooling system stop leak products won't help in fixing these problems. once you have determined cause fix that problem.

White smoke from your exhaust could be several things. If it is just one little puff when you start the motor for the first time and the day is chilly it may be nothing to worry about. However, if its all the time it could be a blown head gasket. I strongly suggest taking your car to a qualified machanic and having it checked out.

White smoke is usually caused by your engine burning coolant. It is usually a bad sign and is normally a head gasket that needs to be replaced if the problem is caught in time.

If it's a large cloud of smoke then water is getting into the cylinder. You probably either have a blown head gasket or a cracked head. Did your motor overheat? If so you probably have major engine problems. My sugestion is to put Gasket seal into your radiator and get rid of the car. If you want to keep it, get a new motor. If it overheated so bad it caused this trouble don't try fixing it, get rid of it.

If it is a thinner white smoke then your burning antifreeze.... it could be a head gasket and this will cost a good amount.
If it is thick blue white smoke then your burning oil, I would check the oil level, other than that it could be worn valve seals.

It's probably steam... If so, you will need to replace the head gaskets and/or the intake manifold gaskets.

If it's white smoke be happy. Black smoke bad. Oh yes if you live where it's cold there will always be white smoke.
