Not sure if that engine is direct injected (The 3.5L Ecoboost is), but sounds like the normal sound of a direct injection engine. Fuel is hi-pressurized and injection system has a sound like diesel clatter. I'm still getting used to it on mine - I really only hear it at idle; always sounds to me like valve or lifter problems but I've been assured it's normal.
It's perfectly normal
