Hi Duane, sorry about your troubles. With genny engine off and pressure on the crankcase, and "fresh" water....is your genny coolant water connected to hot water heater? If the hot water heat exchanger failed it could exploit failed head gasket or crack to allow the fw pump to slowly push water int engine....
