Is white smoke normal?

Our answer:

Hi Sap,

A small amount at a cold time of year is to be expected, as it's moisture in the exhaust stream condensing, but a lot of it at all times is worrying, as it means water in the exhaust that shouldn't be. It could mean cracks in the head gasket or within the cylinder head. Either way, bring the car to a good mechanic to take a look at it for you.
