Squeaking Noise - Help

[sharper410]

I've got this squeaking noise that I can't figure out so I'm hoping someone may have some thoughts. I assumed this was a belt or pulley problem but they all check out fine. I even took the belt off and ran it for a few seconds and the sound remained. Another thought was the secondary air pump because it is really noticeable from the right side intake vent. I pulled the relay for that and still get the noise, plus it keeps going long after the air pump should stop. The noise first occurred after sitting for a month or so due to non-stop rainy weather. Just looking for other things that might cause this that I can look into. I'm trying to get this 986 cleaned up to try and sell. Here is a link to a video of it. https://youtube.com/shorts/YdrPGtbv5vI?feature=share
