New engine noise

So on my way home tonight, my truck started to make a clicking, tapping, ticking noise (depends on who you would ask.) I noticed that it only happens when I'm in gear and hitting the gas. In neutral or park with gas applied, no noise. It's coming from the driver's side. 2001 f-150 5.4L, 150K. My bronco's motor just went out and I can't afford to have this vehicle die on me.

Any help? Thanks.

Or the internals of the cat are breaking up? or the EGR pipe is letting go? Might be the spark plug has worked it was loose and not completely ejected yet?

Does it do it more when cold? and silences/ diminishes after warmed up?
or doesn't matter & does it all the time warm or cold?

Are you low on engine oil? How does it run otherwise?

You'll need to get a length of hose or long screw driver or mechanics stethoscope and try to narrow down where its is come from.
