Loud Squealing Noise Civic!

I have a manual 93 honda civic with a d16z6 engine in it. Lately it has

been making this really high pitched squealling noise and I can not
figure out what it causing the issue. If you are in the car and have it

in neutral and give the car gas you don't hear the squealing. Plus if
you sit there and turn the wheel back and forth figuring it may be the
power steering pump you hear nothing. The only time you hear the noise
is if you are driving the car and give it gas. For some reason the only

time you hear the squealling is while applying the gas pedal and
moving. The squeal is very high pitched noise that almost sounds like
something is rubbing or slipping.

I applied belt dressing to all the belts and they don't seem to be
loose at all. What else could be causing this issue? Any help would be
greatly appreciated! Thanks!
