Re: 93 Tempo harmonic balancer question
It could be a few things....
The belt automatic tensioner spring can become weak and the idler pully can be flapping against the belt because it is not holding tension. This could be the tapping sound you are hearing.
Could also be as simple as low oil pressure causing lifter tick.
Of course, the HB could be the problem again. I know you dont want to hear that. BUT getting the new one on is a pain and I have seen a few shops mess this up. Simply because you have to line up the key in the crank with the slot in the balancer and its almost impossible to see. The balancer gets tight on the crank before the key goes into the slot so its easy to be slightly misaligned.
Hope this helps you out some.
