I cannot seem the find the cause of my engine chirp.

I replaced the ider pully, scotch brite the pullies and checked the belt for signs of glazing but found none.

It sounds like it may be coming for one of the main pully?

Any tips and suggestions of what it may be or how to isolate the chirp would be great!
thank you all

Try a new belt even though it looks good.

 

Hey - mine had a chirp too, couldn't isolate the sound source(seemed like an accessory noise, but it wasn't)...got out the trusty auto stethoscope, turned out to be the distributor! The top bushing had went...100 bux from Advance auto.
