No expert but have you removed covers to check for oil at the plugs. If not move a coil and see if the the misfire changes cylinder number. I get the cold as I just did the rear brake lines on our gravel driveway and it was not fun. I never did a compression test on ours but that might give you some clues. Not sure if there is a step by step as you do not want fuel washing your cylinder walls while cranking.. I am not familiar with the code reader but am assuming it's the 4.4 BMW engine.

So far what I’ve done
I replaced valve cvr gaskets and the plug hole had no oil but replaced with new plugs. I have a extra set of coils and kept swapping coils and keep getting misfire codes on that side cyl only mostly 7 and 8.
I replaced all 4 o2 sensors with Bosch and pulled the entire Exhuast out and welded 2 cracks on the cats and changed cam sensors.
The only thing I noticed was that that side cylinder bank had wear on the cam lobs.
I didn’t do a vanos refresh either

Can you clarify the engine as my life has indicated that the jag engine can lose compression on 7 and 8. Obviously you have done a fair bit. I did read somewhere about faulty/frayed wiring or poor connectors. I noticed on our 02 sensors a film like plastic had developed on one of the connectors as I got a no signal/ weak signal from the sensor.
