You're right. I thought I was careful taking it off and I thought I inspected it after I took it off, and before I put it on. Obviously a missing tooth points to the contrary.
Now that I'm about to redo my timing belt job, I have a couple questions:

1. Is there a way to compress the tensioner on the car so I don't have to take it off? One of the bolts is rounding, so I would have to take the A/C off in order to get at it cleanly.
2. I assume that I need to get a new crank pulley bolt even though it was new when I put the new belt on?
3. I'm also assuming that I can reuse the timing belt that I just changed? I don't need to worry about it being compromised from taking it off and putting it back on?

Once I get everything installed I'll update the thread (hopefully ending it with a successful conclusion).


I really appreciate the help from you @mtbtim and @LittleCaesar for all the suggestions and feedback, and of course everyone else that offered advice.
