My buddy has a Harley F150. and he had a ticking sound when ever it was idling. He let it go and he was driving down the road coming home from a trip one time and the engine misfired and started running like crap. It turns out that a spark plug wiggled itself loose and shot out of the side of the engine. I hear this is fairly common with the 5.4s. I do not know if this is your problem. you will have to be the judge of that, but if I were you I would check the spark plugs to make sure they are in securley.

One way to minimize your risk of launching a plug is to change your plugs with the engine cold, torquing the plugs to 12 - 15 foot pounds of torque.
As for the ticking noise, when a plug is working it's way loose, the sound can be mistaken for an exhaust leak.
p james, like the webmaster implied through his questions, we need a lot more info if we have any hope of helping you diagnose the problem.

PS - What country are you in, and what octane of gas are you using?

My Lightning launched a plug almost two years ago.
One Timesert insert, a new plug, and a new COP and I was good to go.

Ok. Well, those heads can have inserts put in them while they are on the truck. No need to pull the engine or pull the heads and especially no need to replace the head. Some people get scared off from inserts, but most of the aftermarket head companies like Patriot put those inserts in every spark plug hole to prevent blowout. My old Lightning had 2 inserts put in it. I did them both. Nothing you can't do in an afternoon with the Kit from Timesert.
Agreed...my brother blew a plug out in his Expedition/5.4. He installed an insert and replaced the COP, with the heads on the motor. He did this about 6 months ago and no problems thus far.
