Coolant in the oil - 15 gallons of liquid in the engine crankcase. Detroit diesel 671 towed in

This GM 4104 detroit diesel 671 powered bus was towed in with coolant in the oil. About 10 gallons of coolant was in the engine crankcase. An ejected valve bridge guide caused the issue. The engine seems to be ok after the event. Cleaning out the oil system is going to take a bit. The heavy rains from the hurricane made towing the bus up the hill impossible.
