Squeaky noise
1990 jeep cherokee.
So I just replaced the P/S pulley and idler pulley also. I started hearing a whinny noise that sounds like its coming from the exhaust of #1. Here's a video i took while running. I pulled each individual plug at a time to try to determine if its a piston issue but sound never stopped. Read that from the haynes book. Sounds strongest when my ear is over the first exhaust/intake port.
Please let me know what it is if you can hear the noise on the video. I haven't a clue.

Power steering pully bent ? Noise is deff a rubbing issue it timed perfectly with belt circulation.

Given your other thread, I was wondering whether you were going to address the squeeks as well.
sound very pully. You could remove belt and spin them by hand to narrow down...

Weird result. I just flushed the engine after a3 day prestone engine treatment and the squeak is practically non existent. I'm starting to think perhaps it's the water pump from being clogged but it's only around 2 years old. Thoughts? Didn't even touch the PS pulley

I would still look to the pulley, as the water pump theory doesn't sound as likely. If its a new belt and the sound suddenly went away, it could be that enough of the belt was rubbed off that it doesn't rub as much and isn't squeaking. You can also get a pulley alignment tool to check alignment (attaches to the pulley and has red laser style LED's that shine on the adjacent pulley). Here is the Gates one:
