oil on front differential

I have oil on my front diff and on the driver side of my engine block. I know my oil filter gasket is bad (part in transit now) and I've heard that the oil separator can go bad or crack. I've owned many BMWs and have always replaced the OS at inspection 2 (before it failed) so I don't really know what the symptoms of a bad OS are.

I'm nearly 100% sure it's not the pan gasket or axle seals.

I can remove the oil fill cap on the valve cover and the engine runs as it does with the cap on. (I know it should stall or run poorly)
