I pulled the head on Patterson last night. I don’t see any cracks in the block nor do I see any obvious signs of coolant, though there might be a tiny bit of residue on the tops of pistons 1 and 2. My initial reaction is that coolant is entering the oil elsewhere. The engine does appear to have a recently replaced water pump. Anyway installing that incorrectly would result in mixing coolant and oil??
The first two photos show how the pistons and head gasket looked right after pulling it.
Then after pulling off the gasket and vacuuming up the dirt:
