[Camaro ZL124]

All in need of some help very frustrated right now. When I drive around and the car warms up it goes away. Here is a video of the car onhttps://youtube.com/shorts/bW11a-JJ6F4?si=lGo7KUL9LPX6Jc4c

My zl1 is making a chirping and squealing noise and I can’t figure it out. Please read list below of things vibe tried to diagnose:

Change spark plugs
Changed oil
Motor flush
Injector cleaner
Took off serpentine belt and ran without them on
Took off supercharger belt and ran the car without them On
Turned all the pulley with my hand
Took off the valve cover and turned the engine on
Checked for loose rocker arms nothing loose
Fuel Pressure rail is at 68-72 with idle
Checked header bolts the are not
Loose
Drive the car and refill the tank so all the e85 can get out of the fuel
Tank
I did not take Off the alternator belt because that thing is hard to
Put back in but I did spray wD 40 on it and still
The same sound.

Its hard to tell from the video. And your rail pressure should be much higher.
