Squeaks on cold startup + light throttle -- Solved...bad Dorman harmonic balancer

[lobo411]

Just got back from a test drive...no squeaks/chirps. Here is the Dorman balancer...notice the shaft-scoring. I'm thinking that the balancer must have been a bit off balance, and eventually the wobble led to squeaks.

Think I found the WOOO sound...I must have tightened one of the ignition coil bracket mounting bolts wrench-tight before tightening the rest of them finger-tight. As soon as I released the torque on one of the bolts, the bracket kind of sprang up. I figure the bracket actually was the source of the sound--at idle, it was vibrating at the frequency that created the hum.
