Anyone want to take a guess at what the noise/noises are in this video before i pull the oil pan to check the rod bearings? And yes. It sounds exactly as bad in person as it does in the video.

sounds very much like rod knock. but then again the intermittent knock seems like it has very recently started knocking?
you're going to have a fun time pulling the pan if your rig is 4wd

I can't tell much from the video, but you have a lot of high-frequency noise (clicks) that could easily be something else. Did you try a "stethoscope" (I recommend the inside of a roll of paper towels) to try to localize (locate) the sound?

Just an update for anyone who may be curious. I pulled the pan on my 1990 v6 4wd runner today, and I found this.



Looks like I found the source of at least some of the noise. I'm still pretty sure something else is causing the higher frequency tapping sound though.
