OK. I'm running through a general health check and decided to pressure test the engine. While testing, I found that air is escaping from the power valve area into the tranny area. The pressurized air is passing around the pinion shaft (the shaft that passes into the tranny area and engages behind the water pump) and passing out the tranny vent tube. BTW, the power valve is in the "L" position. The leak made me think there was a crank seal leak, but the crank seal appears to be tight as a drum.
During a pressure test is an air leak around the pinion shaft into the tranny area normal?
BTW, the pressure in the crankcase leaks down immediately.
