Slight engine knock

Thanks in advance for the feedback guys!

This is what I'm hearing at idle when it's warmed up. Could this be due to low idle issue?

Seems way to inconsistant to be a engine knock. And also seems very hallow and plastic'y. Does it get worse with RPM's? Do you have access to a stethascope? would help pin point the noise.

Just from the short video i would guess something is hitting your timing cover. Would be worth taking the covers off and looking in there. At least the 2 side fronts.

Once those engine covers, front or rear, get oil on them they can distort and flex, maybe its touching one of your pullies? Just a guess

Yeah, I agree it sounds a bit too intermittent and would recommend taking the timing covers off.

Almost sounds like a belt slapping the timing cover... I'd almost gamble your hydraulic tensioner is either dying or loose.
