cause so times if you crash in a rock or a tree . then the oil comes out of the pipe
Maybe a blown head gasket
its when you have either mixed your oil too rich or you need to ride more on the pipe.
Is the smoke coming out the exhaust pipe or from under the car? If its coming from under the car there could be something like oil getting on it. If its coming out the exhaust pipe you have engine problems and you should first check the oil level on the dip stick before your next oil change to see how bad its using oil.
You may have oil on the exhaust, once this has burnt off the smoke should stop.
if it's coming from the tail pipe or an exhaust leak, it means you have a blown head gasket!
it could be an oil leak.. my boyfriend had that happen to his s10 and he had oil leaking into his exhaust system
Serious trouble. It usually means a broken oil (piston) ring. Another possibility is that your exhaust valve seals are bad/gone or valve guide is worn in excess. Another possibility is it is condensation coming out of exhaust mixed with black residue from exhaust and only looks like oil.
Oil is coming out of the tub but what is that a sign of
there is no water mixed with the oil but have antifreeze coming out of the exhaust
Your oil is (most likely) not leaking into your exhaust but rather through the head gasket into the cylinder(s). You have to machine your head and replace the gasket. (I don't recommend trying this on your own if it's your first time) I'm assuming of course that you have BLUE smoke coming out of your tail pipe.... if not clarify...
The burning smell from the exhaust pipe may be caused from oil or transmission fluid leaking into the exhaust pipe. For example, if your turbo is failing on the car, then that can cause leakage from the manifold into the exhaust pipe. There may be other reasons, too, which other people will be better articulating.
Probably that you're burning oil. This could be for several reasons, the most likely being that your piston rings are faulty/worn.
