I was looking at a dampner the other day that was a two piece deal and the outer ring was held on by rivots, (just like the one on my motor) Well this dampner basically came apart while the guy was making a pass My question is, what would happen to the engine during this situation ? Alot of vibration, and maybe damage the valve train from all the harmonics ? The center piece was intact that is pressed on to the crank, but the outside ring was just flopping around w/ all the rivots in the bilge ! So, I ordered a new dampner today, so I don't experience this......but to what extent would this damage parts ??? By the way this was a Professional Products dampner.
