Sounds like the HPDIP (High Pressure Direct Injection Pump) that is fired off the cam on the passenger side. It is loading the injectors at 3,000 psi so it’s a bit noisy. Normal id say. Also could try turning your defroster off, sometimes A/C compressor clutches make noise. Mine for reference if the video loads:
Totally normal 5.0 sound. They all click or clack. I have owned three of them and have friends who also own them. Some with over 170,000 miles. All of them make noise.
Totally normal. Mine also makes some Ticking/Tapping noises and it freaked me out at first too. Ford has referred to these sounds as Coyote-isms before. These are just loud engines nothing to worry about.
