Re: [T3] Gas in the crankcase


actually with our engines  ( well the carbed, mechanical fuel pump engines......
) the most common reason for Fuel in the oil is caused by a leaking/punctured
diaphragm in the fuel pump........  the leak is not always evident on the
diaphragm when it is disassembled.... if this leaks, the fuel has a direct route
to the crankcase.    I have seen this problem quite often.....
