wired sound from engine ?

[pla748]

this sound has been there for two several months, I am not sure if it's normal.
every time when I stop in front of traffic light, I can hear cranking with whistling sound.
Then today, when I got home, I keep the engine running, then open the hood. the sound is loud. Is there anyone has the same sound? is it normal? mine is 2018 model with 47000 mile. Thanks.

driver side with hood open

shut the engine, restart with remote fob

Sounds perfectly normal to me. Every ecoboost we have owned has done that. Expeditions are even more prounounced whining. I kind of like it

Sounds normal. The high pressure fuel pump makes the under hood ticking noise.
