If I'm reading this right, your valve cover (cambox) is over full of oil, so that means its filling OK from the main oil pump but not being pumped out by the cylinder head oil pump.

Before pulling engines wouldn't it be prudent to test the pump output on the bench (or even swapping / comparing pumps with the other cylinder) and if OK, pressurize the pump discharge port in the head to make sure that there is no blockage downstream of the pump.
Even oil from a hand operated oil can should be able to create enough pressure to see if the oil discharges into the sump.....
