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.
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
The two combine to produce smoke.
It could, if it's leaking.
what is the worst for your health breathing in tobacco smoke or exhaust fumes
Bad valve guides or seals
emissions and exhaust
It depends on how bad the smoke is. If the vehicle doesn't run, it could be a blown head gasket or a cracked head.
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
you could be leaking engine oil onto the exhaust or it could just be rusty water that is evaporating and causing the smoke.
If you nicked the oil pan it could cause it to smoke from engine area. Is the smoke coming from the exhaust or engine bay? If exhaust, then I highly doubt it was caused by the curb incident.
the smoke that comes out of a exhaust pipe is supposed to be white
how can i get black exhaust smoke stuck on my dual exhaust
If the smoke is black it could be caused by a faulty fuel pressure regulator which could be causing the engine to get too much fuel.
If the smoke is coming from the exhaust then it's coolant. If its not turning over then it could be hydrolocked from a coolant leak.
grey exhaust smoke is caused by your engine burning oil during the combustion process. this could be caused by a piston ring that doesnt properly seal, or another leak in your engine.
smoke poured out of the exhaust of the car.
Water condensation coming from the exhaust is normal when the vehicle has been sitting in a wet area, but should stop once it is warmed up. Water from the exhaust after it is warmed up and white smoke from the exhaust is an indication of a blown head gasket.
It is buring oil this is a wrong answer whe engine burn oil to the exhaust smoke is a heavy white smoke no black
In a gasoline fueled engine, blue smoke is a sign of oil being burned with the gasoline. This could be from rings allowing too much oil by the piston, a leaking valve guide or even oil being mixed into the gasoline. Two cycle engines, which have oil mixed in with the fuel on purpose, will often produce this light blue smoke at the exhaust. This would be a natural condition.
Blue smoke is from the engine burning oil. You could have too much oil or an internal engine failure.
It means you have a leak in your exhaust line, the exhaust should be completely vented away from the car by the pipe. Since your lungs pass carbon monoxide, one of the components of exhaust smoke, as though it were oxygen, into the bloodstream, but your cells which should be receiving oxygen can't use carbon monoxide, you could die from it. Immediate suggestion, get it towed to a company which repairs or replaces exhaust systems and have it fixed.
What colour smoke?
The answer depends in part on the color of the smoke.
it could be a blown gasket, cracked head or water in the exhaust
Yes, it could. What could happen is it leaks as you are going down the road and leaks onto the exhaust manifold and creates the smoke.
