This means that water is passing through your exhaust system which usually means that either a head gasket went bad or crack or warped head.

AnswerDid you repair the car first? Because if not your engine is probably hurtin' (blown head gasket or warped head). The most common leak in a blown head gasket is the anti-freeze.

White smoke is anti-freeze burning (or boiling) and you probably noticed you're losing anti-freeze from the reservoir. Also check your oil for overfilling and a greenish additive that YOU didn't put in. You can try STOP-LEAK but be aware this DOES NOT provide a permanent fix.

If you have the money have a professional look at your car and fix the head gasket and/ or the possibly warped head.

AnswerI had this problem with a 1975 Honda civic......turns out a cylinder burned a hole and the water mixed with the oil making white smoke come out of the exhaust.

Reason: Improper maintenance. I never got oil changes or added oil. or checked the water or checked for leaks.....Etc...

Repair: Change the cylinder. Very expensive $?

New Engine $500.00 rebuilt (already more than the car was worth) plus Labor$?

the smoke that comes out of a exhaust pipe is supposed to be white

If there is no overheating or loss of coolant, most likely it is due to condensation in the exhaust system (pretty normal in cool or rainy weather).

White smoke from the exhaust indicates you have a blown head gasket or cracked head. Stop driving the car until this is repaired or you will do serious damage to the engine.

white smoke can be either your car overheating, or smoke from an electrical issue

Is white smoke coming out of the exhaust? Is the oil milky? If so then you could have a blown head gasket. You can also check by getting an exhaust gas checker at Autozone to see if there is exhaust in your coolant. HTH.

White smoke from the exhaust means that coolant is entering the combustion chamber. Normally caused by a blown head gasket or cracked head. STOP driving the car until this is repaired as severe engine damage will occur.

I'm not a mechanic / technician , but if white smoke is coming out of the exhaust on your gasoline engine when the engine is warmed up : ( it sounds like engine coolant is getting into one or more of the engine cylinders ) * bad head gasket , warped head from overheating , anybody else ?

White smoke from the exhaust indicates that your car is burning water in the combustion chamber. This is an indication of a bad head gasket.

Yes, and it probably is. When it is cold you will always see a small amount of white smoke from the exhaust as the hot exhaust meets the cold air. That is normal and nothing to worry about. However, white smoke from the exhaust can also be a symptom of a blown head gasket. If the smoke smells sweet that is burnt coolant. If you are loosing coolant with no apparent leak, your oil level is overfull, or the engine is overheating, you may have a blown head gasket. If you have none of these symptoms then you have nothing to worry about.

White smoke is a sign of excess fuel or running "rich".

White smoke means head gasket, cracked head or equivelant.

corsa 1.5 diesel lumpy at start up with white smoke from exhaust returning to normal after a couple of minuets

User Avatar

I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.

if there is white smoke ur vehicle is either burning oil or it is moisture in the gas chamber

White smoke exhaust usually means either a head gasket leak or an intake gasket leak. Both are cheaper to repair sooner than later.
