The only clicking that motor does is the stupid check ball in the Pcv valve, it bounces up and down constantly but no other unsettling clicking or similar noises. This morning I grounded a spark plug on the exhaust manifold and had someone start the truck (wasn't starting well as normal) and it was producing a big fat yellow spark and after shes running it goes back to a nice barely visible skinny blue spark so I'm confident that it was the coil (I put on new plug wires and a rotor as well). Only a couple of cold starts will tell if my confidence is grounded in reality lol
