The long story short is that I got this car (2000 Accord 4cyl) from a friend awhile back, he got rid of it because it started making this noise (nearly instantly) during the short time he owned it. I don't blame him, I would of gotten rid of it also!
Anyway, I have driven this car over 13K miles in this condition. It has not gotten worse. Here is a list of what it is NOT-
-It's not valve adjustment as I have checked/adjusted it twice.
-It's not a timing component as I have replaced the timing belt, water pump, etc.
-It's not the balance shafts, as I have removed the belt and it did not change. It may of gotten a little better with the belt removed but that is probably in my head.
-I do not think it's a rod bearing, as it does not change at all when removing spark plug wires one at a time. I have even run the engine without a spark plug at a time, no change.
-It does not change warm or cold. It may be a little worse cold, but not much at all.
-I have had a UOA done, and it did not show wear that suggested something is failing.
-It's not the camshaft loose.
-The flexplate to tq converter hardware is tight.
Honestly, I think it's a wrist pin, bad piston slap, or perhaps flexplate/tq converter related. Not too worried about it as it's not worth taking stuff apart to search for it (the car is not worth that effort), but it is hard not to wonder.
Anyway, here is the video.
