Has anyone heard of this malady? Making a terrible clicking or thumping sound. Driving me nuts. Mechanic says he can't do anything more. He is 100% confident that is where the sound is coming from but he also just replaced two cylinders on the LE and installed the new tachometer cable also.

Surely this aggression cannot stand !!

Is there a Seneca II or III devoted maintenance wizard out there ? I will be glad to pay for help.
