Your ticking noise could be from the valve train area, but I'll bet your fan clutch bearing is going south. Take out your fan shroud, grab the fan, clutch and pulley assembly and pull upwards. Now watch the bottom fan blade distance from it and the harmonic damper. If that bottom blade deflects more than 3/16" to a 1/4", remove the belt and spin the whole thing. If its very noisy and its run out is excessive, change the bearing bracket assembly. Also order a new belt, tensioner, rod adjuster, and damper. Ill also quarentee you that the belt tensioner is shot too.
