Daewoo Matiz blowing grey / White smoke from exhaust

SOURCE: white smoke coming from exhaust when accelerating

This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

The most likely cause is a blown head gasket,but it could also be a warped head,was the motor overheated prior to the problem starting? The white smoke is steam,check the underside of the oil fill cap and dipstick for a grayish brown residue,check the coolant for a low level and oil conatamination,either of these conditions verify that a head isn't fully sealed.Unless your moderately skilled mechanically this a job to be done by a shop.A good shop will perform a leakdown test to verify this.

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: White smoke coming out of the exhaust when starting the engine?

Its the problem of oil.The oil is getting burned out. The vehicle is either burning oil or it is moisture in the gas chamber if you notice white smoke from the exhaust. This is a common possibility.but in some cases this white smoke is not due to oil burning.In that case   White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Normally this is a sign of a blown head gasket or cracked head. And  this is not a common problem must be repaired immediately. You must STOP driving this vehicle or you will cause serious engine damage. you will have to get both this possibilities checked.
