Thanks. I just drained the oil. No metal on the magnetic drain plug and no glitter in the oil. Surprised to find zero coolant either. Only had 2.5 quarts in the thing, holds 12 plus 1 for filter. Radiator is full of empty nut has that mustard paste in it and the overflow. No signs of external leakage, so it had to blow between the cylinders some where. Maybe two different failure points. Just doesn’t make sense to not find coolant in the oil but yet have both be pretty much empty.
