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.
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…
Why would white smoke come out from your tailpipe only when accelerating hard and your car shows no signs of overheating?
This could be due to a number of reasons. The fact white smoke is emitted has nothing to do with overheating. The most likely reason is the burning of an oil based product by the engine. This could have been introduced via the gas tank or carbuerator. ie, an engine or carb cleaner. If no products have been introduced it is possible that the rings in the engine have failed, allowing oil to enter the…
I'm not a mechanic / technician but if white smoke is coming out of your tailpipe with the engine warmed up it sounds like you are getting engine coolant into one or more of your engine cylinders . ( bad head gasket / warped cylinder head ) Is the coolant / antifreeze mix also going into your engine oil )
What would cause black smoke to come out of one of the exhaust pipes as the truck has duals on a 1993 Chevrolet Suburban with a 5.7 L engine It does not do it all the time however.?
What would cause white smoke to come out of a muffler if a car was not run for a few weeks but was fine prior?
White smoke out of the exhaust is a sign that the head gasket is bad and is allowing water (coolant) into one or more of the cylinders. If the smoke decreases when the engine warms up, this may mean that the gasket is expanding when the engine warms up. Check for coolant in the oil by looking at the oil on the dipstick. A sure way to tell is to tell is that the oil…
What are the different symptoms between a cracked exhaust manifold vs blown head gasket and a very reliable mechanic said the car backfires and blows smoke and that it is an E. M. but is this accurate?
A cracked exhaust manifold should not cause a backfire, unless your engine is running extremely rich. It would, however, cause the engine to sound very loud and smoke to come out from the engine compartment. If your car is newer than 1996, than a cracked exhaust manifold would turn the Check Engine light on. A blown head gasket would cause coolant to leak into your cylinder head, which would cause large amounts of white smoke…
What would cause the service engine light to come on the heater to not work puffs of smoke to come out of the heater vents and the anti-freeze to blow on a 2004 Mazda 3?
That is not good, at all. That could be a blown head gasket, or even a crack in your engine somewhere not visible. The only way to tell is to tear your engine down and find the problem. It would just be best to take it to a certified mechanic. To be sure it is coolant and oil, does your exhaust smoke come out Light Blue?
