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).

SOURCE: exhaust blowing white grey smoke lots of it and

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).

SOURCE: Car is smoking on start up, a lot of white smoke

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.

Excessive exhaust smoke on the first start of the day


Sounds like the valve guides are leaking oil into the cylinders, or there is a coolant leak somewhere. Usually white smoke is coolant but could be oil.
Are you adding either fluid often ?

When I start the car especially after sitting for 2+ hrs I get a very shaky rough start and white smoke. I does however start on first turn so far.


ther may be a problem with the valve guide seals, allowing oil to drain into the motor as it sits, when you start is it runs rough until the oil is burnt (the white smoke)

generally your problem can be traced to a faulty anti-drainback valve in the fuel pump. After sitting for an extended time fuel must be re-filled and pressurized before engine will start. Second primary cause is a leaking fuel injector which does the exact same thing from the other end of the system but, this is also accompanied by a puff of smoke after starting.
Other causes can be low comrression from engine wear, or, a weak ignition coil but these are far less common.
