Hello i have been in a battle with a random ticking at idle and its driving me crazy. I replaced the following, valve cover gaskets, Iridium Bosch Plugs, changed the oil, and wiped clean the coil packs. The wires were still in very good shape. It does not have a mis fire, i do suspect a vacuum leak but im not concerned with it right now. It runs great and idles smooth as can be, but the vacuum leak makes it rise up and down slightly. BUT I AM MORE CONCERNED WITH THIS TICK! I have a video i will upload and post the link.

Thanks for the help, I owe it to the forum for saving me hundreds in labor.
