I'm rebuilding a 1935 chevy 216. It has new everything! I just put it together, cranked the oil pump to get oil to the lifters, and out comes oil from the rear main. (I had NAPA do the machining to crank and install bearings. He said no main bearing seal was used in these old engines). Well---I have oil comming out of the rear main. Any clues as to what went wrong?? I need help!! Thanks, Wayne
