Oil can come out of the exhaust of your lawn mower when it is tilted to the extreme, especially when the crankcase is overfilled with oil. A clogged air-filter can cause the oil to spill out of the exhaust vent, so simply replace it if this is the case.
Oil leaks are relatively common in the area where a gasket is placed between the cover and the cylinder head, which keeps the engine oil from leaking out. The engine also has a valve train, which is covered with a rocker or valve cover, one cover for an inline engine, or two for a V-style engine.
Oil leak to outside of engine: Oil leaking down the side of your engine likely means the head gasket has blown between an oil gallery and the outside of the engine. Even though this type of head gasket failure isn`t as immediately severe as others, you should still look into repairs before it gets worse.
This very often happens when the tractor has just been left ticking over or engine idling at low revs for a long time. The reason is that oil is passing the rubber seats on the exhaust valves. Give the tractor a good hard days work or drive it up a steep long hill for an hour and get the engine hot.
Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
Cracked Gasket: The Core Culprit in Most Engine Oil Leaks

More often than not, a sudden oil leak after oil change is caused by a malformed or cracked gasket. Gaskets are usually made of urethane or rubber, and they can harden over time.

SOAP is often the best answer, especially for oil tanks, jam solid soap into the crack, best applied like you would grate cheese, push the soap across the crack forcing soap to block the gap and stop the leak.
