Default Help identifying this noise

Anyone with experience, do you hear the slight squeak/chirp? Any idea if this is the beginning of a lifter roller?

Only thing I can hear, is what sounds to be a idler or tensioner pulley bearing starting to go dry for about a millisecond of noise.
On the main belt, you have the T with is the tensioner pulley, while the I is the idler pulley.
On the inner belt for the Ac compressor, you have another T pulley on the bottom of the page, that you can pull get to once you remove the outer then inner belt.
As for removing the a/c tension belt, the pulley to re-grease it, standard 12 point 15mm wrench, with it U side cut off, and a piece of 6" 1/2 EMT as a cheater bar works get in the tight space. Just keep the bar tight against the box end of the wrench as you get it on the bolt flats from the top of the motor downwards, then pull the cheater back back out a touch to get a bit more leverage on the wrench.



Here is how to re-grease the bearings (while still in the pulleys) once you have them in hand.

All I hear is a healthy engine.

Likely, idler pulley. Very common.

I hear the sound you’re referring to but it doesn’t sound like anything serious. Where does it seem to be coming from? Does it sound internal?
