The dampeners have failed. Ask Trips.There have been a couple of long threads on them. If you want to install an aftermarket dampener. Get an ATI dampener from MA Motorsports. The Z motor is dampened. That why you see the rubber between the ring halves on the dampened. Remember the oil pump is mounted to that end of the shaft. And there have been oil pump failures at high rpm. Some believe it's caused by harmonics.
