I had my tensioner pulley bearing go and my pulley ate a hole through my timing chain cover before I got home. When I took the tensioner off the round piece of my timing chain cover fell into my timing chain cover. The truck still ran fine before I pulled the tensioner off and I do have 06 f150 out in the yard. Will the timing chain cover work on my 2000?

 

No. The 2000 is a 2 valve, the 2006 is a 3 valve. Completely different. 1997 through 2000 5.4 in any vehicle are compatible, including the V10 in the Super Duty. Doesn't look like 2001 and newer will work.
