The harmonic balancer broke on my 1994 Buick Lesabre, it was replaced and now I have a lot of clicking in the motor. The faster the motor runs, the louder the clicking. What could that be? Thank you so much for your help.
I didn't see 3.5, saw a 3.8L. The crankshaft position sensor is behind that pulley, make sure it isn't hitting anything? Check oil pressure. You might be able to use a long metal piece, One end on the valve cover the other end to your ear or the bone behind your ear, It helps to magnify the sound. You just have to be careful not to get the metal piece caught in a belt--pulley--fan, something like that.
Another thought is a halfshaft joint, usually I only hear that at very low speed.
