If it is a ticking, I don't think plugs will help. I hate to say it, but it takes a trained ear to recognize sounds like this. To me, I feel it is most likely a lifter that is collapsing. Are you able to take the vehicle to a mechanic and have them listen to it? It should only take a second or two so they shouldn't charge you for it.
Let me know.
