What causes oil to mix with gas in crankcase?
Fuel dilution in oil is a condition caused by excess, unburned fuel mixing with engine oil in an engine crankcase.

If you have a pressure tester, connected it to the fuel fitting. This will tell you if the seat will hold gas or not. If the seat can hold 5 P.S.I., then it is ok. Install the fuel bowl and nut.
What causes crankcase dilution in an internal combustion engine?
Crankcase dilution is a phenomenon of internal combustion engines in which unburned diesel or gasoline accumulates in the crankcase. Excessively rich fuel mixture or incomplete combustion allows a certain amount of fuel to pass down between the pistons and cylinder walls and dilute the engine oil.

Where does gas go when it goes into the crankcase?
Any leaking through or around the needle valve or seat should just run out on the ground through the overflow if its not blocked. If the fuel is getting into the engine anyway, then the diaphragm in the pump is probably leaking directly into the intake through the pulse line.
Why is gas going into my crankcase / bad petcock?
But if the petcock is good and turned off when parked as it should be that shouldn’t happen. Any leaking through or around the needle valve or seat should just run out on the ground through the overflow if its not blocked.
