You can really here it in this one. When I built this truck and got it running. It had this crazy "tick" to it. So I let it sit through the winter and tore it apart again. Did everything over cause we couldn't find what it was. Put it back together. Same freaking noise. I was fed up with it by then so I said the heck with it and ran it. Never had any issues with but was always curious what it was. Still to this day I don't know. Anyone else have an idea? Valves were not hitting, I do know that.
