Little Help Please
Newbie problem! Got a 2004 Lariat Supercrew 5.4 with 120K, have the run of the mill cam phaser ticking it does not bother me, but now I an actual metal knocking sound only on acceleration around 1500rpm when the truck is warm. Searched to no avail can't find anything on this topic. Any help would be greatly appreciated.

It's louder than your typical cam phaser sound and only there around 1500 to 1800 rpm if i accelerate above that it will go away ! It sound like a hammer against the frame and just as loud!
