Default Knocking while running and while foot on gas

Hey guys, I’m new to the forum. I’m having an issue with my 2000 XJ sport recently. I found the tube to to the back part of my manifold that goes into the block was broken. I replaced it but now I have knocking coming out of the manifold while it’s idling and why I push the gas. Anyone have any ideas what could be wrong?
