Why would smoke come from behind the engine?

Bend over a little farther... doesn't that feel good to see the oil leaking leaking out of the valve cover? Probably not, but those are common for leaks, I think it may be a valve cover gasket. Get a neoprene one, not cork if you plan to change it your self. Could be leaking from anywhere back there I have seen them leak from the distributor. Check and see if you can spot the leak you may have to power wash the engine first if it is very dirty and greasy.

I agree, oil leaking from the valve cover gasket will seep down the engine and burn away when the engine is hot enough. That's why you will probably notice smoke coming from the engine (in your case the back).

I suspect that when you come to a stop in city traffic you see the smoke leaving through the grill or from under the car, and a small wind might even help it move into your cabin if the windows are open. Valve covers aren't that expensive to replace on older cars, but on newer cars labor can be more.

This is not that uncommon. Some oil is so hot that it will start to smoke. The smoke can escape through this opening to the engine.

White smoke coming from the engine can mean many different things. One such thing is that your car may have a blown head gasket or that oil is burning in the engine.

Yes, if the the engine is a steam engine or a diesel engine. The diesel engine smoke should be almost invisible when the engine is in good condition. Electric locomotives are not typically called "engines", but these do not produce smoke.

blue smoke is oil. white smoke is water. black smoke is unburnt fuel

The drivers side of what? The tires? The brakes? The engine? Please be more specific.

the engine is burning oil. blue smoke oil white smoke antifreeze black smoke excess fuel

The smoke you see may be moisture/steam. The heater core is probably leaking engine coolant. If the "smoke" has a sweet smell to it, it's engine coolant. More info about the vehicle such as model and year would help.

Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.

the smoke comes out the rear of the car in a pipe. the smoke comes out only when the engine is on. you do not have to be moving to have smoke come out. just the fact that the engine is on creates smoke due to the byproduct of the fuel and energy.

No, the engine exhaust is what comes out of the tailpipe.

If your block is cracked engine coolant may be leaking into the combustion chambers.

White smoke will come out of a vehicle's exhaust system when the engine is cold. This is because of condensation build up in the engine and exhaust. The white smoke should go away after several minutes of idling. If you engine is always blowing white smoke, regardless of temperature, then it might be burning oil. Check the levels of your engine oil and your transmission fluid (if you have an automatic) and have the engine compression checked for blow-by.

I was told that it originated in WWII. When the field artillery guys had extra ammo that they had to get rid of, the platoon SGT was in charge of disposing of it. He would most often go into a field to do this. As he would come back, there was a pillar of smoke behind him.

Smoke can come from several things. White smoke when first starting on a cold day is normal. Black smoke indicates the wrong fuel/air mixture. Blue smoke indicates that the engine is burning oil.

A fire would be the main cause but if there are no flames you should have the engine checked for problems under the hood. There maybe a leak of some sort and it may be burning on the engine.

If that smoke is more like steam, you have a leaky heater core.

If it is really smoke, then it is almost always caused by burning of oil that enters the engine due to bad seals and rings.

No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.

Blue smoke is burning oil.Blue smoke is burning oil.

well the smoke takes four days to actually come out the body.but i would advice you NOT to smoke after that again.
