You have bad, dried out valve seals. When the engine is off, the seals dry up and allow oil to leak into the cylinder, which burns off as the somke you see on startup. But when the car warms up, oil gets back into the valve seals and they swell up enough to keep more oil from dripping into the combustion chamber, so the smoke goes away.
What else can I help you with?
What causes gray smoke from the exhaust?
Blue/grey smoke is usually oil. White smoke is usually coolant in the exhaust. IE: blown head gasket or something. note: if the smoke goes away after it runs for a minute it's oil runnung down the valves when it sits. Common problem, won't hurt anything.
What might be the causes of intermittant smoke from your exhaust Goes away after a few minutes?
White smoke = Coolant entering the combustion chamber, most likely caused by blown head gasket. Black smoke = Overly rich fuel/air mixture. Blue smoke = Engine is burning oil.
You have white smoke coming from your exhaust?
White "smoke" in the exhaust usually means there is moisture in the exhaust stream.If the "smoke" appears while you're driving away shortly after the car is first started on a cold morning it is likely the condensation boiling off the inside of the exhaust pipes (steam). This is normal and goes away as the exhaust warms up. The condensation is also normal; it usually happens after the car is shut off on a cold day and the water vapor in the exhaust gases is allowed to condense as the exhaust system cools down.If you have white smoke all the time, you may be leaking coolant into the cylinders which could mean a head gasket leak. Usually there is oil residue in the exhaust as well, which would be a tell tale sign of a blown head gasket. Then the white smoke would have a hazy blueish tinge to it. Also, certain chemical engine cleaners and fuel additives can create a white smoke. Have a mechanic check it out if necessary.
How do you spell chiminney?
If its that vertical tube that smoke goes up , from burning, then it is 'CHIMNEY'.
Is it normal to have oil to come out tailpipe when head gasket is bad?
no. when a head gasket is bad coolant goes to the exhaust pipe and causes the car to smoke alot all white smoke.
If after you take off from sitting at a light you get smoke from the exhaust but it goes away could this be the valve?
Most likely the valve seals. They allow oil to seep into the cylinder(s) when idling. After you accelerate the oil is burned and the smoke stops being visible. Chrysler 3.0 engines are famous for this, watch some Chrysler mini-vans at the stoplights.
I have water running out the tailpipe of my jeep?
If you see water on start up, and it goes away this in only humidity in the exhaust system. There is no danger. If on the other hand, you continue to have water or white smoke all the time, have a pressure check on the radiator to check for leaks or blown gaskets.
Why does your car smoke when you turn?
only smokes when i put in oil, after about 3-4 days goes away.
How do you know when a vacuum modulator goes bad?
When the vacuum from the engine sucks in transmission fluid from the bad modulator and shows up as heavy blue smoke out the exhaust.
How do ATV exhaust systems work?
the spent exhaust gas goes out the exhaust
Why does your 2002 Saturn Vue v6 3.0 have a humming noise in the mornings it goes away after a few miles?
The humming noise can be in your exhaust system. The exhaust will heat up and seal the area where there can be a leak. The hot exhaust will cause the noise to decrease.
What is causing 1999 GMC sierra to put out white smoke when first started and lots of white smoke when driven but smokes goes away after driven for awhile?
If you're sure it's "smoke", then it's probably burning oil. But most likely it's water vapor. When an engine is first started and the air is cold, the water vapor in the exhaust will create visible steam. Automotible exhaust primarily consists of carbon dioxide and water vapor. If the engine and exhaust system are cold, the exhaust will be cooler when it comes out and it can create a cloud of water vapor. However, if it's not water vapor, as I mentioned above, it could be oil smoke. If that's the case you need an engine rebuild since you probably have bad rings. For the record, I haven't seen many newer GMC's that burn oil.
