If you are having a lot of white smoke all the time the car runs then check for coolant mixing in with the oil,look for water in the oil when you check the oil or milky brown oil. This produces a white "steam" that is very thick to come out of the exhaust. If your engine temp. gauge is very high and over heats you probably have a blown head gasket. If it has a bluish tint look it may be burning oil. Indications might be how much oil is currently in the car i.e too much oil, or if there is a leak in the line you may be adding a bunch of oil over a short time. If it is only when you first start the car and the engine is cold, then it may be that your valve seals are bad and need replacing. Hope this might help or at least give you some ideas...

AnswerIt's coolant. headgasket, cracked or warped head, intake manifold or gasket, or cracked block are your sources. Take it to a care car service to have it checked AnswerAre you sure the smoke is white or is it a light blueish color start the car and have someone stand in a position to see the tail pipe and see if much water comes out with the smoke if it does and you have been running low on antifreeze i would say a head gasket if no water and not low on anti freeze look at worn valves or valve seals or worn rings good bet on these two items good luck AnswerBurning oil in the fuel would cause black smoke so it definitely has nothing to do with that. White smoke can be caused by water in the combustion camber or unburned fuel. If you've be having bad gas mileage you probably have a problem with your fuel or ignition system or timing. You can usually smell the fuel in your exaust when this happens. If you smell no fuel and you've had no change in fuel economy check for water like one of the previous posts said. AnswerTry the changing PCV, it work for me when white smoke(rock concert-like) would come out of the exhaust every time the car was turned on. That was the only time the white smoke would come out in my case. If it is a constant white smoke emitted from the exhaust, especially while driving, it could be something else. AnswerOne thing that I noticed, is that when valve seals get some years on them, a little bit of white smoke can emitted from the tail pipe when you first start it up or when you set at a stop light idling. But usually not that much smoke. Old valves could be causing you to run rich. AnswerSomehow water has or is being burned,check coolant level and temp if you have temp light put a guage in if coolant low there is your problem if not check egr valve and pcv valve also check oil level if high and milky there is high possibility that you have blown head gasket and or block may be cracked allowing oil to get into the oil pan. Answeri think it would be a blown head gasket or blown head

No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.

engine coolant getting into an engine cylinder from a bad head gasket , cracked or warped head

blown head gasket,it causes the coolant and gas get mixed in cylinder,that cause the white smokeyou also loose compression which in return you loose power

Yes. It also depending on what kind of stop leak and how much is used.

White smoke from the exhaust is a sign of coolant entering the combustion chamber. Most likely cause is a blown head gasket. Stop driving this vehicle until you have this repaired or you will destroy this engine.

no way your clutch is going to cause smoke from tailpipe i am a toy. tech 15+yrs you may have more than one problem one of them being your mechanic

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.

Blown head gasket. Or a missfire cause by a bag ignition coil, fouled plugs, too little fuel pressure, timing is off ect.

Blue smoke is burning oil.Blue smoke is burning oil.

If it is blowing white smoke out of the exhaust tailpipe when the engine is at operating temperature, engine coolant is getting into an engine cylinder from a bad head gasket or some other problem

I would say no. It sounds like water is entering the combustion chamber from maybe a bad head gasket.

There could be many problems related to smelling gas and seeing white smoke from your tailpipe. Some suggestions would be the head gasket. If the smoke has a blue tint to it, it may be oil related. If your car has a turbo, it may be the turbo needing to be replaced. To be sure, you can have a mechanic do a diagnostic on it.

I know the white smoke would be caused by coolant, which would be leaking into the combustion chamber.

If your block is cracked engine coolant may be leaking into the combustion chambers.

Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.

White smoke out of exhaust is usually indicitive of water or coolant in the combustion chanber/ chambers of the exhaust. Usually caused by a blown head gasket. A costly repair. clean pipes to and from intercooler and clean intercooler .and clean crankcase breather.

blow by through the turbo ,my truck did the same thing had to get the turbo rebuilt

Take it to a mechanic right away. The white smoke is from fluid mixing with the oil in the engine. Its probably the head gasket.

White smoke from a tailpipe is caused then coolant and oil are mixed together. Typically, this is caused by either a cracked block, cracked cylinder head, blown headgasket. Have engine diagnosed at a shop of your choice. It is not a cheap fix but driving like this for long periods of time will cause engine to overheat and cause more problems than you would like.

I had that happen to me with a V8 I was driving once. Turned out that I had a crook head gasket and oil was being sucked into cylinder head burnt and then out the exhaust. That is white smoke, You it might also be worn oil rings, (white smoke) Or if you are running on a rich fuel mixture you may be blowing black smoke.

White smoke usually means that anti freeze has entered the combustion chamber most likely through a hole in the head gasket and cannot be burned but is vaporized. too much and the engine will not run, which is good since running it in that condition would do more damage than just a blown head gasket.

it would cause overheating but the smoke is probally coming from some sort of water or antifreeze in combustion chamber
