Notice when it starts, the ticking is not there but comes on about 3 seconds after it starts. When the engine is reved the ticking goes away. Notice in the video that the center section of the SC pulley looks off balance. The noise has become a bit louder in the last 10 miles. I have not driven the car in a month but around the block 2 miles. Any ideas.

Turn your volume up a bit.
