1998 Mustang Knock Help! Spun Rod Bearing?

[junkhead]

Hi, I'm a new member and was hoping somebody could help me figure out this knocking. On a cold start no noise at all but when it gets warmed up I start getting a loud knocking noise. I'm posting a link to the video I took today any help would be greatly appreciated! I tried seafoam already. 1998 v6 3.8l

If you disconnect the plug wires one by one, does it go away or diminish significantly on any particular cylinder?

Thanks for the fast reply! I'll give that a try first thing in the morning
