Can you tell if the smoke smells like oil? If it does, and it does not clear up after running for about 10 to 15 minutes, then it could have serious internal oil leaks and bad gaskets, rings or other seals that can be very difficult and expensive to fix.
If it doesn't smell like oil near the car, then it could just be water turning into steam in the exhaust. Even then, if a coolan leak inside of the engine is causing it, then it could be a problem, or could be as simple as water getting into the gas from sitting a long time.

Persoanly, just because there are too many things that could be wrong with it and because Cavaliers do not hold their value very well, I would not risk $500 on it if it's more than 6 or 7 years old in any case.

SOURCE: Nissan Sentra 2000 model. Thick White smoke coming out of exhaust

White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event.

Let us know how it goes or if the problem persists. We're looking forward to how things go for you.

SOURCE: white smoke coming from exhaust, smells like gas

Check the fuel pressure regulator. It should have a vacuum line attached to it - disconnect the vacuum line and turn the ignition on - if fuel come out then that's your problem. DON"T do this while the engine is hot or you could start a fire!

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.

SOURCE: thick white smoke coming from exhaust

I would think this will be a blown turbo.

These are fed by a small oil pipe and if the unit overheats (due to wear) - this oil fill feed directly into either the inlet manifold - or the outlet - exhaust.
If it is spilling oil into the hot exhaust - you will get a thick white fog. You can confirm this by placing a clear glass bottle or jar in the exhaust stream - and see if it gets a thick coating of oil on it. If it evaporates - it's water, if not - or feels oily - new turbo or overhaul.

Best get is sortd sooner rather than later - as you may be able to save most of it for an overhaul rather than scrap it if badly worn.

SOURCE: car is blowing white smoke from exhaust when i step on gas

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.

White smoke coming from exhaust,need help


White smoke is condensation from a buildup of water from within the exhaust system - if it was blue smoke then it is burning oil ... let car sit for a few minutes and take the dipstick out - wipe it clean - then re-insert dipstick - take it back out and check level against gauge at bottom of dipstick if you think you may have overfilled the oil

My car has white smoke coming from the exhaust


he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

Will only stay running on revs over 2000rpm if I take foot of peddle it cuts out also white smoke from exhaust


What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

What causes white smoke or steam to come out of the exhaust?


white smoke is an indication of coolant in the combustion chamber. I would suggest having a compression test done as there may be a gasket problem or cracked head.

I have a nissan sentra eccs with automatic transmission 1993 model, the exhaust is releasing a lot of white smoke, is this normal?


sorry but if you have white smoke coming out your exhaust, most likely you blew a head gasket. antifreeze is leaking into your exhaust and out the tailpipe. check your engine oil dipstick and see if the oil is a milky color. your local auto parts store sells a temp fix for it just ask for a head gasket sealer. good luck

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.
Thanks. you can rate this solution and show your appreciation.

My 2002 cadillac deville white smoke from exhaust


Head gasket. There is antifreeze seeping into the cyllinder when it's not running. When you start it, it won't fire properly until that water is blown out the exhaust. Once it's gone, in a few seconds, just like you describe, it'll run fine. The antifreeze is then being blown out the exhaust. Re - white smoke.
