Go to another shop and get a second opinion. We cannot hear the noise and can only guess. Get a couple of opinions before making your decision.

Use a long screw driver. Put it to the timing cover. Then put the handle to your ear. Youll hear it. Then u can put it on different componites to trace the noise down.

When I take off the belt and run the engine the noise goes away.

Then it is an external pulley or bearing making noise. Spin all the pulleys to see if you can hear the noise.
