White steam from exhaust

When the engine is again started the exhaust system will heat up evaporating the water causing steam. As the engine warms up and the condensation dissipates the white exhaust smoke ( steam ) is no longer seen. This is generally steam caused by condensation. When it’s cold outside and you notice white smoke at startup, then you probably have nothing to worry about.

When the warm or hot exhaust gases meet cold outside air, condensation and steam is a result. After a short amount of driving, the white smoke should lessen. You may commonly see white smoke coming from the exhaust on cooler days upon starting. If smoke is being release then this is indicative of a problem.

HOWTO looks at all the possible reasons why white smoke is coming from your exhaust pipe. The smoke escaping from your tailpipe is actually steam and will appear more gray than white in color if examined closely. The water is the result of an accumulation of that same steam as it makes its way through the exhaust system and out of the tailpipe where it condenses from its gas form back into liquid. THere are 130K miles on it and I am the only owner.

I drive roughly 2miles a day mostly highway. When I start my car, a significant amount of white steam will come out of the exhaust after a few minutes.

Re: Steam coming out of exhaust ! I have the same white smoke on my 4mercruiser. I also have water entering the back cylinder. Running a compresssion test first though. White smoke occurs in a diesel engine when the diesel fuel goes through the engine and reaches the exhaust without having been burned. This typically occurs due to the engine being too cool to burn the fuel, often resulting from low compression in one cylinder, problems with the fuel injection timing or a defective fuel injector.

As a car owner you expect something to come from the tailpipe. Smoke coming from a motorcycle exhaust indicates the engine is not running correctly. Typical problems include fuel not being completely burne too much oil or coolant evaporating. If ignore such problems can result in significant engine damage, and being able to identify the origin of the smoke, as quickly as. On cold winter days, it is common to see white smoke from exhaust pipe as soon as you start the car.

Excessive White Smoke From Exhaust. When the smoke emitted is thick, white and billowing, this usually points to a crack somewhere within the internal combustion engine which is allowing coolant or oil to leak out of the areas they should be contained within. The coolant is then being burne producing the thick white smoke. Usually with white smoke you’re either spitting out vaporous un-burned diesel or steam. To tell the difference between the two is fairly easy, if your engine is making white smoke right from start up and the smoke sits on the water without disappearing you’re most likely looking at un-burned diesel.
