96 2wd 2.3 squealing like a banshee...help!

[JackieAnn]

I have a squeal coming from the engine bay. I removed the serpentine belt, started her up for a minute and the squeal remains.
I have replaced clutch, pressure plate, slave cylinder and pilot bearing.
The crazy thing is it's not all the time. It's squealing most of the time, but once in a while it will go for almost a day absolutely quiet, then it starts again.
The squeal sounds just like a belt or pulley is bad. It rises and falls with rpm.changes, and at idle is barely noticeable.
No problem starting or running, it shifts fine, I just can't seem to figure out what's squealing.
I took it to a buddy who is a tech for Ford. He listened to it and it sounded as if it was coming from the passenger side rear of the engine, and not the timing belt area.
When I get under the truck, it seems really loud neat the oil.pan area.
And advice would be helpful. I'm going nuts trying to fix it haha.

I too going nut trying to figure out the squeak on mine. First, I though it was the tensioner. Original belt tensioner, replace it and it goes away for a while. Idler, replaced it and go away for a short time. It is seem to be from the bell housing. I also did a clutch job. The only thing I didn't do was to replace the flywheel. It does have some "hot spot" but roughing it up with sand block, seem to do the trick.
