Balancers are prety common on that engine. Mark the inner and outer with a crayon, then run it and see if the marks still align. It's not hard to change if you have the puller.

Loose torque convertor bolts will make a bearing knock type noise.Could you describe the noise if it's not the bolts or the balancer?

noise

My wife was driving the car when it first started making the noise.And she said at first it sounded like the belt slipping. When I checked it sounded like a valve tapping and now sounds like motor is adout to come apart.Three people has listened to it and two said it was the main. One said mains just dont go out like that and said it was the balancer. Oil pressure is good and it has not been ran low on oil.I haven't drove the car, but my wife said it seems to not want to go like should when she gives it gas. We're not driving the car now. Would the balancer cause that to happen.

I marked the balancer and ran the motor for awhile and the marks was still lined up.

Just to be sure, put a socket on the center bolt of the pully and slowly turn the engine in both directions and make the the belt moves with it immediatly.
