SOURCE: clouds of white smoke
Dense white smoke usually indicates coolant/antifreeze getting into the combustion chambers. This can be from a "blown" head gasket or from a crack in the cylinder head or the block. In either case, this involves some major work on the engine. Replacing a head gasket is preferable cost-wise to replacing a cylinder head or the entire engine (block).

The white/grey smoke is steam (water). (from the cooling system)The engine has either blown a head gasket or there is a crack on the engine block.
Stop as soon as safely practical at home or wherever you will work on it.
Before you spend lots of money, try an engine block sealer, less than $15. Bar's Block Seal, for example. Read and follow directions carefully. You may need to apply twice. May also last for a couple of months or several years.
Otherwise, replace head gasket on affected side and/or replace engine (block).

If the engine is using oil then first remove the dipstick and run the engine, check to see if heavy smoke is coming out of the tube, this would indicate worn piston rings,if it is not so dense, yet you are using oil and it smokes bad from the exhaust, then its likely the valve seals are worn. either way, unless you have mechanical knowledge, tools etc , you need to take it to a mechanic for the engine repairs or live with the oil consumption. There are no quick fixes for engine wear.

white smoke is usually burning oil but if the catalytic converter was clogged then it could just be a build up of carbon and is normal though you should get the converter changed as soon as possible to prevent further damage.
