ticking or clicking noise

[kennyhammond]

When I drive it or hold the brake and give it has you hear the ticking or clicking noise increase with rpms but you put it in park and rev it to 3k or so and not a noise one... It increases with rpm when in gear but nothing when there is not a load ...ibran two cans of sea foam thinking maybe it was carbon build up ... Any ideas. I checked exhaust for leaks no signs ..
