I doubt that's the issue, as when I saw a mate have it miss aligned. The engine simply would not start. But to check, you would need to drop the gearbox.

Did you end up getting a cheap oscilloscope? Because you maybe able to see if TDC from the crank and bank 1 (piston 1) line up. or is there a way to view this in ISTA/other tools?
Did you end up getting a proper compression tester?
What about pulling the plugs(injectors, coils) on the knocking cylinders. To see how it runs with them off.
Given everything replaced, whats the current list of issues/errors.

Maybe***
If reading correct, The error is only on 1 bank. If TDC from crank and cylinder 1 line up, maybe swap over the cam gears between banks?
