Just rebuilt a 312 everything is fine except a I developed an oil leak that comes out the out side bolt of the oil pump. It is not a bad leak but a constant drip . It developed after about 50 miles. the first time and now right away after I change the gasket. I have replaced the gasket twice and the same thing happens. everything is torque to spec

Any suggestions would be appreciated
