4-53 Detroit diesel, 2 cycle engine? Fuel in the crankcase? Caused buy leaking injector lines or injectors. If you remove the rocker cover and crank engine, you may be able to see the leak. Or you can plug the return line and pressure the inlet line to head, and pressure check to see leak. It needs to be repaired. The diesel in the oil will ruin the bearings and cause crankshaft failure!
