motor was running fine, went fishing for hours. then it started to smoke white and died. seems to be flooding out, pulled the plugs to find milky oil, checked the pressure and both around 120. pulled head to find the gasket was damaged, didnt see any cracks in the head, replaced the head gasket and still running rough and seems to be getting some but less water in the cylinders. could this be the exhaust gasket or plate? or could it be the thermostat?
