No it is not good. Coolant is getting into your combustion chamber and burning. Check for oil in the cooling system if so possible head gasket

Hi wite smoke from the exoust wen under compresion and then exalarate it is gone . have done the rings ,velve stem seals and turbo kit and stil smoking .


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 you still see white smoke when the engine is warmed up then you probably have coolant leaking into the combustion chamber. Possible causes are warped head, blown head gasket or cracked block. Do you have unexplained coolant loss?
Good luck.

First start with making sure the engine is purged of air, and you have no thick white smoke coming from the exhaust in back. 2 sure signs of a blown head gasket are, thick white smoke. next is , leave the cap off the reservoir/radiator. If it throws the coolant back out at start up, it's bad. Not there, next is to do a compression test on the cylinders. Low or no compression is bad gaskets also. These are the first things to check and do. Before just throwing money at good parts.

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.

I have a 2005 jeep liberty that has white smoke coming from the exhaust when idling and it smells like burnt firecrackers after driving it when I turn the engine off. Any ideas?


If it is the v8, the most common cause for greyish, white smoke is bad valve stem seals. True white smoke smells very sweet and is caused from coolant being buring in the combustion chamber.

Excessive white smoke from tail pipe


White smoke:

White smoke is caused by raw, un-burnt fuel passing into the exhaust stream. Common causes include:
·Incorrect fuel injection timing
·Defective fuel injectors
·Low cylinder compression

Low cylinder compression may be caused by leaking valves, sticking piston rings, ring wear, cylinder wear, or cylinder glaze. When white smoke occurs at cold start and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing.
Continuous evidence of white smoke indicates a mechanical defect, or incorrect fuel timing.

White smoke from exhaust


The white smoke you are seeing is steam. From your description, sounds like you have coolent seeping into the combustion chamber, mixing with your fuel/air, and exiting out through your exhaust as steam. 1, blown head gasket. 2. cracked head or block, 3, warped head due to overheating. Most common is #1.

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.
