White smoke is usually caused by water in the ignition system(blown head gasket or water in the gas tank due to condensation. If it clears up after running for a while, you should try a gas conditioner in your fuel tank. If its constent, then do a compression test and to check your head gasket. White smoke is water; Blue smoke is oil; and black smoke is flooding or too much gas. ADDED NOTE: I have had an occurence where a brake fluid leak(at the master cylinder) allowed the vaccuum operated BRAKE BOOSTER to suck in fluid into the intake manifold, causing WHITE SMOKE..

White smoke from the exhaust is a symptom of moisture in the combustion chamber. If you see it after that initial startup, then suspect a blown head gasket. A compression test will verify this.

White smoke that smells sweet, is coolant in the combustion chamber, normally caused by a cracked head or a blown head gasket Blue smoke, the engine is burning oil.

Why does my 2003 4-cylinder Toyota Solara have white smoke coming from exhaust 5-10 seconds after startup regardless of temperature though less likely when cold does not smell like antifreeze?

White smoke at startup (when the engine and exhaust have completely cooled down) is usually caused by condensation. It's especially noticeable in cooler weather when the car is used for short trips. The engine never really gets totally warmed up, existing condensation in the exhaust isn't completely evaporated. In short, what you may be seeing is simply steam vapor. If the smoke isn't white but is more gray or blue/white it's oil. A few seconds of oil smoke at startup is usually caused by leaking valve stem seals. Oil drips down the valves and onto piston tops when the engine is idle. On startup the oil is burned causing a few seconds of smoke. The puff of burning oil is most noticeable after the car has been sitting awhile, like overnight. Unless the seals are really bad not enough oil drips into the combustion chamber during shorter stops to notice any smoke. Cheers


Porsche 944 has heavy white smoke on startup?

Heavy white smoke is indicative of a blown head gasket or cracked head/block. Coolant is probably leaking into the combustion chamber. Run a compression test to further diagnose. Another reason is that you might be burning a lot of oil. does the smoke disappear like steam or say in the air?


Is it normal for white smoke to come out of the exhaust at startup of a 2000 Rav 4?

is there a sweet smell? Does the coolant level drop in the overflow tank and/or the radiator? if so, you might be looking at a bad head gasket. if there is slight white smoke(usually condensation) and no loss of coolant, then it is normal. once the engine (and exhaust system) gets hot, there should be no more smoke.

What would cause you to have a puff of white smoke at startup or stopped at a red light from time to time?

or it could be worn valve stem seals. which causes a little bit of oil to build up on the valves when you shut the engine off or stopped at idol. this is burnt offon startup or when you takeoff.


What does white smoke mean when you start the car?

A very small amount of white smoke at startup is normal and is nothing more than condensation in the winter. However combined with a loss of coolant with no apparent leak, overheating, white foamy substance on the underside of the oil fill cap, or overfull oil level, means you have a blown head gasket and or cracked head.


1988 Silverado 12 ton 150000 miles when running a lot of white smoke comes out of tail-pipe It does this when you start it or when driving what causes this?

White smoke is an indicator you have a head gasket leak. The white smoke is actually water or coolant mixing into the combustion chamber with the fuel and air. Have you noticed a bit of a rough idle? Have you looked at your coolant level lately?


If the engine light came on at a stop light and it is sputtering and white smoke is coming from the exhaust what is wrong?

White smoke is a good indication you have a blown head gasket. And/or a cracked head. Did you noticed, when it happened that the engine started running rough? Best i can do with little info.


How do you know if the head gasket it blown?

White smoke from the exhaust especially at startup. Coolant mixed with the oil. A white foamy substance on the underside of the oil fill cap. Loss of coolant with no apparent leak. Engine overheating with possible miss.


Why is your car smokimg from the engine when you start it up?

My car isn't smoking, but if yours is it would indicate that it is burning oil. You may have to stop at a gas station and fill up the oil and check the gas. My first guess would be valve seals. If there is white smoke on startup it could be that the feul mixture is too rich on startup, that is for gasoline /petrol engines in a diesel engine it could be from a low grade diesel ir faulty injectors Sorry, white smoke is oil, black smoke would be too much gas. white smoke could also be water, but it would heed to warm up some before you see that.
