84 sedan 4x4 with a auto trans,...there is a sound from the belhousing area when its cold, its kind of a knocking sound that happens intermintantly, the tach jumps when it knocks and there is good amonut of powerloss, however when the car warms up it runs fine and there is no noise and powerloss, and the tach works fine, its got me stumpped, i thought about the flexplate because i can stick a prybar in the timing hole and move it forward and back, so any ideas?

 

thanks dusty

anyone? im kinda in a bind here

symptoms point to bad bushings in the distributor

see if the shaft wobbles

 

connection to knocking?

maybe the drive gear is knackered

and it locking up

 

 

flex plate flex?

Well I can move it fore and aft with a pry bar, almost as if it was loose, I havebt checked the disty, that would explane the tach symptoms and the power loss and misfires
