Now I know most of you are probably gonna say right off the bat, "rocker hitting the valve cover" or somewhere along the lines of that, but I'm almost positive it isn't. What's happening is ONLY
when I go down the highway, there's a faint ticking noise that gets louder with acceleration. Doesn't do this in town or at idle. Reason I don't think it's a loose rocker is because it did this before I even touched the motor back in June. I don't know if it's just a normal thing for these trucks or if there's something loose hitting the rotating assembly. Has anyone else had this happen before? I'm at a loss
And note that the noise hasn't gotten any louder or quieter before or after the engine modifications. Also doesn't affect the way it runs because this thing is getting faster the better the weather gets
