This can be caused by a cracked head or blown head gasket.
It's fuel exhaust, like the exhaust from a car. Like a car the largest component of rocket exhaust (at least from the combustion of its hydrogen fuel) is water, The white "smoke" you see is essentially steam like you get from a hot kettle/.
have a mechanic check your turbo.most will tell u that a turbo blows black smoke but can aslso blow white smoke when turbo is malfunctioning
how can i get black exhaust smoke stuck on my dual exhaust
You car has an exhaust system attached to the engine. The exhaust can get to upwards of 300o and then because of that, water that touches that hot metal turns into steam resulting in the "smoke" you are referring to. This also applies to the engine when wet.
oil leaking onto something hot like an exhaust manifold
Considering that if you have black smoke your car is running too rich. Blueish white smoke from the exhaust means it burning oil. Depending on exactly where this white smoke is coming from it is most likely transmission fluid that is burning. A bad seal or gasket on the trans will cause it to leak. Especially when your car is hot and the tranny is shifting, this will cause more pressure on the leaks thus forcing out more fluid. This form of excessive leakage shoots out the fluid which then hits the exhaust manifold or exhaust pipe and burns up very quickly producing a thick white smoke that if your driving it seems to be coming from the tailpipe but actually is coming from the front center of the car. A good way to check is to go to a quarter car wash, spray off the bottom of the car, and any parts of the exhaust manifold or pipe. After driving for a while, and it still smokes, you should be able to see freshly burnt on stains on the exhaust system. Also don't forget to check your trans, fluid lvels. Mark H.
Most cars have a little white smoke on start-up, but a consistent plume of white hot smoke is caused by antifreeze leaking into your combustion chamber and being expelled as steam. This is a bad thing.
That smoke is steam. You have a leak in the radiator or a hose. Take it to a mechanic.
Yes, and it probably is. When it is cold you will always see a small amount of white smoke from the exhaust as the hot exhaust meets the cold air. That is normal and nothing to worry about. However, white smoke from the exhaust can also be a symptom of a blown head gasket. If the smoke smells sweet that is burnt coolant. If you are loosing coolant with no apparent leak, your oil level is overfull, or the engine is overheating, you may have a blown head gasket. If you have none of these symptoms then you have nothing to worry about.
you have a blown head gasket
just run engine until it stops smoking out of tail pipe. If it stops emitting white smoke and you move the car it may start smoking again because there is a possibility that some water in exhaust has been moved onto hot areas so just allow it to run more. Ensure no more water is leaking into exhaust.
Sounds like you have a blown head gasket. If you get white smoke out through the exhaust, you may also have a cracked cylinder head.
