replace the crank shaft damper while your at it or it will do it again in about 2 years.

Hmmm you know ive been doing this for 18 years and ive never put 2 and 2 together to even think about the vibration damper causing this. We learn something every day.... Thanks for the input on that and it makes complete sense.
