Bad piston rings and/or bad valve guides or seals , 4 stroke engine. The oil and gas mixture in a 2 stroke engine. Or it could be left over gasses that are being expelled from piston chamber after the engine is shut off.
cause so times if you crash in a rock or a tree . then the oil comes out of the pipe
The fumes are most likely coming from an exhaust leak. The leak could be at the converter, or somewhere else in the exhaust system.
Sounds like engine coolant is getting into an engine cylinder
The three things that could cause black smoke which come to mind are: 1) You have a belt or pulley problem which is causing the belt to slip and burn. 2) You have an oil leak that is getting on to the exhaust and burning. 3) The mower is running rich. Which means it is getting too much gas. The most common of these is choice 1. Oil leaks don't normally get onto the exhaust since most exhausts aren't under the engine. The running rich problem also does not normally come from under the mower. It would typically come from the exhaust unless it has an exhaust leak.
You need a head or intake gasket. Coolant is getting into engine. Head more likely.
White smoke out of the exhaust means that there is coolant getting into the combustion chamber. Usually due to a bad head gasket.
your exhaust may be jammed
there is no water mixed with the oil but have antifreeze coming out of the exhaust
Is white smoke coming out of the exhaust? Is the oil milky? If so then you could have a blown head gasket. You can also check by getting an exhaust gas checker at Autozone to see if there is exhaust in your coolant. HTH.
It could be condensation from hot exhaust gases on the cool exhaust pipe.
