If the white smoke comes out when the engine is warm, then you have a head gasket leaking. Give the warm exhaust a smell, if it is a sweet smell then you deffinitly have a head gasket leak. Pull the dip stick out and check to see if there is any foam/ frothing on the dip stick. This will tell you if the coolant is leaking into the oil passages and if it is, do not drive the car. The coolant will wash your rod and main bearings causing the rotating assembly to fail. The proper fix is to replace the head gasket and have the head checked for warpage. Do not use coolant system repair compounds as they will plug your heater core and now you have that to replace also. I hope this helps.

It could be a blown head gasket, or intake manifold gasket leaking. give the car a compression test to check the readings on all the cylinders, the 1 with the lowest reading is in the area of the blown head gasket, this will have to be replaced.

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: 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: 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?

If your not overheating or losing coolant, its more than likely engine oil burning. If it is coolant related, possible blown head gasket.

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.

White smoke coming out of the exhaust when starting?


Hello;
Volumes of white smoke is an indication of water in the exhaust. A certain amount of vapor will be present on start up, but if it is different than what has been the norm for this vehicle then a check of the cooling system is in order.
