With 60,000 original miles on a bullet proof motor with known reliability, it was not on my mind. Can't believe it really. I will have him take off valve covers and take a look. Just is case all heck broke loose up there. That's a long shot but has to be checked before teardown. If he does not have a double chain I will have him convert. Any other ideas before teardown????
