What causes crankcase to fill with gas?

What causes crankcase to fill with gas?

Causes. Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. Another way that the fuel oil can end up in the crankcase is because there is too much wear on the piston compression rings.

Why is there gas in my oil on my Generator?

A generator will typically have gas in the oil when the float needle valve is not seating properly in the carburetor and gas works its way by the piston and into the crankcase. Generators with external fuel pumps that have a hole in the diaphragm will suck gas into the crankcase with each stroke of the piston.

What to do if you have gas in your generator?

Undo the clasps and remove the filter, and then remove any of the bolts holding the air filter assembly on to the generator.
