What engine does your 2009 F150 have?
Is it a high pitched ticking noise or more of a deeper knocking noise?Have you been able to scan the PCM (Engine Computer) for any trouble codes?
The 5.4L 3 valve engine has its share of problems. We have found the camshaft followers (used to be called rocker arms) break and fall off the camshaft and cause a ticking noise. If it is an intake valve, you will not feel much of a miss fire, because the engine has 2 intake valves per cylinder. But only one exhaust valve and if that follower falls off, you will have a severe miss fire. We have also see the camshaft phasers cause driving issues and ticking noises. They advance and retard the camshafts with oil pressure. Also the valve guides are known to go bad and cause ticking noises, but not performance issues and the noise from them are louder under the fender well than on top of the engine.
