I thought that as a possibility when this ticking first started...Until I added a half bottle of Ceratec, and the ticking was suddenly quieted down. Then, after adding an A/C compressor belt tension arm, the tick has been subdued even more. To me that indicates whatever it was, is definitely internal, and not related to the DI system. Unless oil circulates through the DI injectors to lubricate them, I just don't see how.If the tick/rattle is what I think it is I come from the High performance Duramax world, truck has dynoed over 1100hp. Being a diesel we have had direct injection though it is at much much higher pressures. We have what is known as injector clatter/rattle where you can actually hear the injector solenoids resonating at certain rpm and to me this "rattling" sounds almost exactly like that. On a diesel if you are running high Pulse width and lots of duration which is essentially causing the injectors to really "work" you can hear it like crazy. One thing to note is if people have removed the huge engine cover on the 5.0, it could be heard on the coyote engine a bit more as you don't have something to really absorb the sound. However this is just my theory I could be completely wrong on the subject I was listening to my buddies 5.0 which makes the same sound.
