My car has white smoke coming from the tail pipe...

White smoke from the tail pipe is moisture/water turned to steam.It comes from the air drawn into the engine and/or coolant in the engine.If you see excessive white smoke and your coolant level is dropping,you are most likely steaming coolant.Oil burning usually comes out as blue smoke.

A heavy presence of white smoke from the tail pipe is usually caused by a bad headgasket. If this gasket is bad, the vehicle may run rough as well as overheat.

Where is the white smoke coming from? Under hood? Out tail pipe? If excessive white smoke from tail pipe, suspect a head gasket failure which in turn will fill the cooling system with exhaust pressure forcing the coolant to come out of the reservoir and resulting in an overheating problem

Probably have antifreeze leaking into the exhaust system - head gasket.

Are you saying you have smoke coming out of the tail pipe ? Or is something dripping onto the exhaust pipe and burning ?
If the smoke is coming out of the tail pipe, is it blue, white, or black ?

Possibly a blown head gasket, letting coolant into the cylinders to be burned. White smoke is usually coolant burning. Have the engine's compression tested to verify.

You don't say what the make model and year is, but yes it could be an intake gasket.
It could also be a leaking head gasket among other things.

U have a blown head gasket the white smoke is burning coolant

cylinder head valve seals needs to change.
