I bled them according to my shop manual and put everything back the way it's supposed to be. Wouldn't you know it, the tick is still there. I have no idea where to go from here. Is it possible that the valves are damaged or the clearances are out anyway? I really have no idea what the sound could be. If anyone has any ideas on what the problem may be they would be greatly appreciated. Thanks Matt
