So long story short I had the BMW dealer mechanic look over my car for basicaly free, and he noted that my valve cover was cracked (or my gasket wasn't clear). I haven't had the time to look under everything to confirm if it's cracked, but I can smell a significant amount of oil being burned off. So it's leaking hardcore.

Although the valve cover gasket is well protected from the top and bottom, it is very delicate and prone to damage from the sides. And will crack due to exposure to dirt, debris, heat and other elements. When this occurs, the gasket can lose its integrity and will leak, potentially causing cosmetic issues with leaking oil or reduced engine performance.
