Can anyone help me, this morning all of a sudden the car started give out a lot of white smoke. What would be the reason. Is it because of cold or something went wrong overnight. Thks

 

White smoke indicates burning coolant, but if it's even a little bit bluish it could be oil. The coolant will smell more sweet; the oil will smell like burned oil

Burning oil will generally not cause too much harm right away, but burning coolant can. There should never be coolant in your combustion chamber, and if there is it is likely due to a headgasket issue. If the coolant is also getting into your oil, you can destroy the engine pretty quickly by breaking down the oil film on the bearings.

 

First, does the white smoke go away? I blew a headgasket on my Mazda once and it smoked like that all the time and consumed antifreeze. But my Audi smokes in the morning and it does go away as the car warms up. I chalk this up to condensation in the cylinder heads over night. It has been cold here lately -20C.

I would look at your oil if it seams cloudy then I would suspect Head Gasket.

 

exactly what cheeba said. Probably would be a good idea to minimize running until you have a good understanding of the problem. Buddy blew his motor because of the coolant leaking into it.

 

i agree, however, i have noticed in the few weeks i have owned mine the exhaust does seem to have more water vapor in it. and until the entire exhaust system is warmed up it will condense the vapor to form the "white smoke" you see. If you have a head gasket issue, it would look like your car is still running when you shut it off, especially after you have been running it for a while. also another tell tale sign of a head gasket issue, if thats what you suspect, is a boilign sound from your engine after you shut it off. coolant will leak into your hot cylinders and boil, producing the steam and the boiling sound.

 

Man, that is scary stuff. Wouldn't your vehicle start to overheat if your headgasket is leaking?

 

depending on the extent of the leak. my brother had an 89 toyota pick up that blew the head and it drove fine till he parked it. a small drip will produce vivisble smoke, with little antifreeze loss. if you truely think your headgasket is blown(cracked, warped, deteriorated, ect.) watch your coolant level and check your oil. if your not loosing any coolant, and theres no "cream" in your oil, probably not your head gasket.

 

I can recall of only one time when white smoke blew out of my exhaust, but it only happened after two days of sitting without starting the car and the exhaust cleared up right away.

Nadeem, you should get your car checked out. Does your car throw any codes at all? How's it been running lately? Any recent maintenance?
