Yes, he told me to put a little extra in the donation plate at Church to thank the higher power that the valves weren't bent or it would have cost us a lot more. Apparently a bunch of teeth (?) got sheered off of the belt at the bottom, I saw it and yes, the belt was in pretty rough shape. The mechanic said it looked like it had never been changed (remember I have 200k miles on this Xterra!) I am very happy with this old-school mechanic and will certainly go to him from now on.
