2000 Blazer 4.3 Tapping noise in engine

I noted a jumping motion in the fan belt tensioner and with a screw driver steth i find the noise loudest in the pulley. I expect to hear "its normal" when i take it in for other items and would appreciate an "experts" opinion (knuckles). thank you.

Sounds like a bad pulley.

Document them telling you it's "OK" in writing this way if there are problems later on, you can take them to task with "told you so".
