Nc engine knocking noise. What say you?

I have a bit of a dilemma. I just noticed a weird knocking noise and not sure its the stupid noise producing solenoid that i disconnected or its the flipping engine piston rods. It comes from the solenoid side but unsure… any ideas? Edit, oil levels ok (above the second hole on the dip stick) Noise filmed from the inside [nc engine knocking noise inside] Noise filmed from the outside [nc engine knocking noise outside]
