I didn't have to pull the timing cover to see this.

Something is screwed up here. There should be a sleeve on the crank that the seal rubs against and this does not extend beyond the front cover. There should be no slot visible either.The key that holds the pulley is a about an inch long and should be fully visible. I have never seen a pulley break in this area.
