Hi
Yes a bad damper will cause you grief.
Years ago i put new front tires on a Frieghtliner with a 3406 Cat.
I had the hood open,and was changing the tires on the rims without removing the rims.At one point while the engine was running with the hood open and you could see the damper was shot and the engine wasn't idling smooth.This truck had just been bought by a sawmill.I told the owner about it.The truck broke the crank on the first trip with the new tires.
It got parked then sold,new owner replaced the engine the block got damaged too.
