Oh, this is a "Second Time Round" fast food motor! See the chisel marks where they felt "Steaking in Place" the galley plugs would keep them installed! Oh, what a bunch of Idiots. You have no idea how many of these "Staked in Plugs" I have found in Oil Pans! Most of the time the motors could keep running for a small time. Other times complete oil pressure loss and cracked crankshaft or broken rods!
