5.4 3v has a knocking sound
I just replaced the oil pump, timing chains, cam phaser deletes, cam followers, lash adjusters, I use mobile 1 synthetic 5-20 and motorcraft filter. Finished it up truck sounded great driver about 200-300 miles and boom now sounds like an old 7.3 at idle. Not just start up.

I had same knocking issues....tensioner had broke and chain was slapping front cover. Used the 4 part series on YouTube that had all links to parts, torque specs ect. FLAWLESS! You must use all Ford parts, high volume oil pump. Yrs it is a little more cost but well worth it when it comes to frustration. These are the links
