Injector cups will leak fuel into the coolant not oil. Cavitated block would most likely leak coolant into the crank case therefore coolant into the oil. I can't think of anywhere in the head that coolant and oil run side by side where a crack would dump oil in the coolant but I guess there are a couple places where they don't usually crak that could possibly leak hpo into the coolant. But you'd probably pump all the oil into the coolant pretty quick that way. So most likely it would be the oil cooler.
If you look in Docs pic the oil cooler is the horizontal piece just under the exhaust manifold. The rearward end is the part the oil filter attaches to. Could be as simple as a blown seal between the two so you might get away with a cheap o-ring fix rather than having to replace the whole cooler.
