I can not think of any reason why you should be leaking oil out of the exhaust manifold. You are right, everything would just burn up if any oil was in the exhaust gas. So look for another problem. See if the oil is being blown onto the manifold. You have an exhaust leak. If the oil is deposited there, the oil bubble would form like you described. when i did the head on my car, I had the exhaust manifold decked because it was leaking. The shop set it is very common to have a warped manifold after a exhaust leak. You may have to remove the manifold if you want to fix the exhaust leak. Look around for an oil leak elsewhere. make you a bet that it is coming from somewhere else and being blown onto the manifold.
