Troubleshooting white smoke from exhaust of car
When the white smoke is notice to come out from the exhaust at any engine temperature such as when the engine is cold, warm or hot suggest a problem on the head gasket in which the gasket might be ruptured or have crack.

In case you are not aware, the engine is surrounded by water to cool down the engine. Now the purpose of the head gasket is to prevent the water that surrounds the engine from entering the combustion chamber. When the head gasket developed a crack because of wear and tear the water that surrounds the engine will leak out into the cylinder, this water will then be burned and become steam that will come out the exhaust as white smoke.
