I hadnt thought about the dampener but it is my understanding on 7080s and 8070s is a fluid dampener and they dont go bad

They do.

Keep in mind these tractors are 40-50 years old...

Im not sure what sound you are hearing with your engine or what rpm etc but the ambac injection pump leaves a bit to be desired. If its never been rebuilt its probably time. The governor inside them is very toutchy. My 8070 with the ambac pump had a strange sound i noticed when roading it at around 1600-2000 rpm. the governor would quiver and very quickly fuel and defuel causing some black puffs from the exhaust and a really strange sound from the cab. It was quick. probably 3-5 times per second it sounded almost like a misfire on one cylinder. turns out it was the injection pump governor quivering. Just a thought. Hope it helps

They are silicone filled but there is nothing that says they can't go bad. Have seen pics of cut open ones that the silicon was "dried" out.
