A couple weeks ago I had my OEM headers coated and reinstalled without the heat shields. Also had the oil changed. I can barely hear the valve train anymore without the heat shields on.

correct. LM and Motul 10w60 oils are thicker then the stock BMW Stuff, and the s65 bearing design is flawed from the factory. They prefer oil that’s more of a thin 10w60 or thick 10w50.
Once the LM or Motul breaks down, the engine will quiet down. These oils will provide better long term protection.
I’d recommend trying 10w50 if you are looking into using a better oil.
