The fluids can mix one way or the other or both. Sounds like you have a Failed headgasket.

you might want to check your timing chain cover, if the chain is loose enough, it will rub the cover right at the oil passage at the water pump area and the oil pressure being higher than the cooling system pressure, it will pump oil into the coolant & it is very difficult to detect without pulling the cover.
