Sometimes white smoke is actually gray smoke. Does this white smoke disappear in a short amount of time (like steam) or does it linger? White smoke represents the presents of water inside the combustion chamber. A bad head gasket can allow coolant into the cylinder/s. If it is gray smoke. This is usually oil getting into the combustion chamber. Bad valve guide seals or worn or broken piston rings will cause this. You may want to check both the engine oil level and coolant overflow reservoir, Degas tank and/or radiator. Please let me know if there is anything else.

Hello!
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck

That white color is a tell tale sign of a bad head gasket, when the head gasket goes your coolant mixes with your oil and the burns off causing the white smoke. I hate to give bad news but it's not cheap or easy to replace.
Hope this helps

You are smelling burning antifreeze. likely a head gasket but only testing will determine that for sure...Do not drive it. get it to a shop or more damage is likely.

Yes, the best way to determine if you've blown a head gasket, it to use the diagnos # 4 gas analyser or smog test analyser- (the tube that goes up the tail pipe), place the wand near the radiator. if the wand reads finds CO in the cooling system ,100% blown head gasket

To begin with, check for fuel in engine oil and do a compression test. If fuel system is not functioning properly (running rich) that will point you in one direction (temp sender, pressure regulator , map or airflow sensor etc) If compression is low, you may have internal engine problem (burned piston, broken ring, or combination of fuel problem causing gas washed cylinders)
