5.4 knock
I've got a 2007 HDPP f150 with the 5.4, it seems to be making a knocking/slapping noise, not sure if it's a piston, connecting rod, piston bearings or some else. My 5.4 doesn't have the cam phaser issue, just changed the spark plugs and coil packs and did an oil change, same noise as before. Truck has 278000 on it, just want to figure out what noise it is so I can replace the parts sooner than later
