Help me identify this noise please!

So here’s the deal, 2012 Raptor 24k miles. When it’s cold, it has this annoying, difficult to distinguish noise that is mostly heard in the cab. After 25 minutes or so it seems to go away or atleast faint enough that I can’t hear it. Under higher power settings it also goes away. Difficult to hear at idle unless really cold. I stabbed the mechanics stethoscope everywhere and can’t seem to find the location.

I told ford about it twice and got the same old “could not duplicate“ saga.

checked coils, no arcing that I can tell.

I thought manifold leak but no obvious signs.

Cam phasers.

But seriously, I can't hear anything abnormal. Listened to the video over 10 times. Are you talking about the wi e after you hit the gas as it is spooling back down? Maybe an idler pulley is starting to go.

I wish I could upload the whole vid but it’s a tapping noise especially noticeable when it’s spooling down. between 1000 and 2500 rpm spooling up

I remember @FordTechOne had mentioned the 3.5TT has a tapping noise from the injectors. Not sure if the 6.2 does the same or not.

I recommend listening on an iPhone for best results. Sounds different on my iPad

The injectors I’m used to from my X5m. This is not the injectors. the noise is a touch deeper than the injectors. Thanks for troubleshooting with me though!

Does it change with engine speed?

it gets louder but the hertz value doesn’t seem to increase all that much.

Pop the belt off and see if the noise is still there. Don't run it too long, but long enough to get a good listen.

It really doesn’t seem to be the belts, not that my belt doesn’t need attention. It can best be heard with doors closed at 1000 rpm.
