I'd suggest pulling and cleaning the oil pan, replacing the pan gasket and
reassembling, then flush with 75% oil and 25% kerosene. Just enough revs to get
oil
pressure. Run about 15 minutes and drain. Replace filter, refill with oil, drive
about 500 miles (800 km), then change filter and oil again.
