hello and greetings.
dropping belts was savvy !! way to go.
There are many sounds, possible. some are simple others not so.
It sounds like rod knock but i cant hear the double knock of it. a rod like to knock twice, as it changes direction bottom and top of cylinder.
mains like to know lugging and engine up hill.
it can be piston slap, that is not a big deal. (if not piston cracked cause)
use %5 stethoscope and listen all over engine. Everywhere, even engine mounts. take your time,...

1: the exhaust header end loves to fail.. if the doughnut gasket there, is bad , it sounds just like rods or mains bad. scary.!
SO I took my cave man stick or board and jammed it at header, and frame and reefed it over and bam, dead silent. (the cold chills ended )
2: then on the 97 the thing made this same class noise. found the rear mount on the huge aluminum MAIN AIR pipe mount broken, huge sounds. there.
this pipe ends up at the MAF. the head has a mount to it, that can fail at head mount or like mine broke the aluminum pipe tab mount. off, and even sucked air there
a double trouble failure.
that is my best idles here.
lots of places Noises can source. in and engine. IN ENGINE or anything connected to it. this engine shake it has no Silent shaft, tech,. off crank.
cheers.
