My pickup started making a knocking noise this evening. I shut it off when I got to walmart after I let it cool down and when i got back out, started it up and drove home I noticed a kncoking noise. It only does it at idle when you first start it up and slowly fades away, but hwen you rev it up anywhere above idle it knocks. It it coming from the top of the motor as far as I could hear. I don't run my H&S on anything but stock and its only been deleted about 500 miles, only 4,700 miles on the pickup. Any experience with this? it's not the typewriter noise, I've got that too.
