On the cheap yes. Drain the Oil, turn it upside down, remove the bolts, remove the oil sump carefully, scrap off the old gasket, clean real good. put the oil sump back on carefully so that you don't jack-up the position of the governor arm, then seat all the bolts and torque to (7.2 - 10.1 ft-lb). Also, something to consider being that the engine was manufactured in the late 80's and probably over 30 years old and going this far into the repair (which is almost half way to a complete tear down) why not rebuild?
