Default 5th gen prelude Engine Clunking and Cylinder 4 Misfire

Hey fellow honda enthusiasts,

I've been dealing with a persistent clunking sound coming from my engine. I've gone through all the usual steps to address a misfire, but the issue seems to persist.

I've replaced the spark plugs, wires, the ignition coil, distributor, and even the fuel injectors/pump/filter, but the clunking sound remains. (it is properly timed and has good compression across the board) Has anyone encountered a similar problem before, or does anyone have suggestions on what might be causing this issue? I'm attaching three videos to illustrate the problem, hoping that visualizing it might help identify the root cause.

Video 3: Noise when revving

Your insights and expertise would be highly appreciated! Thanks in advance for your the help.
