How about a bad or missing valve stem seal on the exhaust valve? Oil could leak down the guide and get blown out of the head on each exhaust stroke. You would need to pull the valve cover and then remove the valve spring and such to test, but better than pulling the head or even the exhaust manifold to see what is going on. I wonder how much play is in the valve guide.
