Engine knock/rattle
My engine recently began knocking/rattling at lower RMPs (
), anyone have any idea what is going on? I recently replaced the intake manifold, but I have no idea why it is doing this. Thanks in advance.

I'd like to say it's something simple, but from that video, it almost sounds like bad crank bearings. I hope I'm wrong, as it is hard to say without being there.
How's your oil pressure at an idle with a warm motor?

that actually sounds like the typical 4.6l timing chain rattle when the guides start to get worn.
You could also have a sticking lash adjuster , or even a bad cam follower.
