odd noise is driving me crazy.....please help.

[84LX89GT]

Heres my problem:
On my way to a friend's house today my car started making a weird noise. it sounds like what a weak belt tensioner would sound like, or something that's vibrating in the belt drive...or something like bearings (high pitched metallic loose/wobbly noise). At first I thought it was the tensioner so i took the belt completely off and messed with the tensioner and no stoppage of noise. It sounds more like it's coming from the back bottom of the engine (Definately from the passanger side) like the starter doesn't fully disengage or something.....here's the weird part: it ONLY does it with the engine rotating (while running or dead) on LEFT turns. Right turns there's no noise and it intermittently does it at idle at a stop, but doesn't do it coasting with the clutch in or out of gear with the engine off. On left turns it gets louder and with the clutch in it occasionally makes a little noise.
ANY IDEAS, PLEASE HELP!

-by the way, this is on my '84 LX 5.0L-
