Ok, you have the CRANK PULLEY which is held in place by a 17 or 19mm bolt (depending on the year). Crank pullley has belts that run from it to the alternator, AC, an on certain cars Power Steering (PS)

Now you describe taking the bottom end apart, but the CAMSHAFT pulley is located up top, on the side of the head. and theres only 4 bolts taht hold it in.

Sounds to me like its your alternator pulley, the bolt is probably loose and the belt is squealing, pretty common, replace it, its a $3 part.

IM me on AIM and ill send you the COMPLETE CRX service manual , ditch the haynes, it sucks donkey balls
