I have the same clicking problem. I was told by the dealer that there is no fix but not hurting the engine (do not believe). I was told by an owner of a Lincoln Navigator that had the same problem and told the same thing b Ford but went to another service center and they fixed it by replacing the 7 and 8 plug. No more ticking. I think I need to try this.
The noise sounds like lifters, but since there are none in this engine, I initially thought that it was an exhaust leak. The other day, I pulled up to a friends house and he said, "I didn't know that you had a diesel."
