I know that the 4.6L's tend to have loud injectors (most if not all of that ticking you're hearing) and there's a TSB on it worth diddly squat; Ford would say that's normal. My only suggestion would be to try a 5W30 in lieu of the recommended 5W20 and see if that quiets things down a bit. It won't hurt anything. IMO, that sounds pretty normal other than the 4.6L being known to be a bit noisy.
