Wasn't planning on replacing the chain now since the car has only 76K miles. I just wanted to insure that I didn't break one of the rails because of brittleness or too much chain play.
I rotated the cam 4x and every time it came up at the 18 mark. I suppose the ringer on the damper could have rotated some back when I replaced the water pump last year. However, when I did that job I only loosened the damper but never fully removed it!
