2005 F150 5.4 ltr tapping/knocking sound
2005 f150 5.4 just shy of 89k miles. Maintnanced regularly with 5-20w motorcraft and motorcraft filters. I suspect cam phaser but recently as you will see the knock happens at all RPM's. was not that way a few days ago. Been to three dealers. Two say cam phasers and the third was 50/50 on what it could be. One mechanic said he did not know and a second said Cam phaser for sure. Oh, the check engine light is on because I had unplugged the VCT and reconnected prior to the video,that was not the issue. It will probably take a couple start cycles to turn off....hopefully. Anyone with experience or a trained ear have any Idea?

I need help diagnosing this noise. Any help would be appreciated! If I left anything out that would help than just comment or PM me and I'll be sure to add it. Update: We had the truck taken to a mechanic a week or two ago and he replaced two or three coil packs, a couple spark plugs, and it runs like new. The ticking is gone and it's gained power.
