Desperate to identify chirp that has stumped multiple people

[Jammer24]

I did not read every post. Luv will suggest that you have a cracked flex plate.......happened to me one time years ago....

Does the chirp go away when you put it into gear?

I am sorry I posted about manifold bolts being loose. I should’ve been more specific. Intake manifold bolts, not exhaust manifold bolts.

There is clearly a very pissed off parakeet in there. Let it out.

Unplug the coils or injectors one at a time and see if it goes away.

I’m not sure if this is the right thread but I own a 20 ram1500 Laramie with orp so that being said it has fox2.0 and 1” bigger springs from the factory and running 33/12.50r20 motos with -2 offset I developed a intermittent chirp and grew progressively louder over a 40k time frame while trying to pin point the cause at 105k it was evident the fox 2.0 coil over and springs were done so I upgraded to eibach pro truck 2-3.5 lift system witch included struts ,shocks,and springs. If equipped with off road package you minus 1” due to factory springs are bigger I also purchased ksp forged aluminum upper control arms and precision lower arms with zerks and servicable ball joints. Long story short no chirp anymore I’m replacing the sway bar bushings and sway bar to eibach also in near future will post pic soon if wanted but if I had to guess the actual part chirping I’d say lower ball or control arms bushings but not percent!

Pull the inspection/dust cover off the bottom of the bell housing and look up in there real good, a bright light and a bore scope or other long flexible camera would help here.
Spin the motor by hand, listening, and looking for any shiny spots on the convertor and flex plate, indicating rubbing. Look around the inside of the bell, possibly a loose convertor bolt rubbing, or foreign object in there.
Inspect flex plate real good. I cracked one in a racer once and it sounded like that.
Tap the cats with a hammer, possibly a heat shield or an internal issue.

Nope, it is consistent no matter what, as well as stationary or moving.

Thank you all for the help. I am a bit swamped right now with a family situation and I have 2 finals next Wednesday so I cannot do much until after then. Then I can really check some of the things you all have been so awesome to suggest. I have no ran it full throttle yet either as I have been paranoid it would be engine related and just didnt want to put any unnecessary strain on it. But it runs smooth as butter, effortless power, shifts seem smooth and rides super smooth. Thats why this is so damn odd. This thing drives and rides better than much newer trucks. I couldnt be happier with it, other than the gas mileage. That is a real kick in the **** at the pump, but its a truck, so cant complain, I knew what I was getting.

My was running the same way. Smooth with no misfires, and it didn’t matter the speed of the truck. It was the same constant chirp. I do believe it was the loose intake bolts because I found nothing else wrong with the engine.

You can get an endoscope for 20-30 bucks that plugs into a laptop or phone. I'd use that to look up in bellhousing through the torque converter inspection plate to see if there are any rub marks inside. Engine off of course.
Also, rotate the engine by hand and see if you can hear the sound being made. Might be able to pinpoint it easier that way.

It sounds just like a compression leak, i.e air leak or possibly an exhaust leak. I have heard and seen that on engines that are now antiques or older. To find the air leak location use a strip of paper or yarn and a long handled needle nose pliers. The paper or yarn will wave at you when you find the leak.
