I don't see anything 'milky'. What you guys are calling milky I'd call fresh oil.
I see the front main as the primary leak. In the first pic you can clearly see the clean spot/fresh oil trace up to the bottom of the seal.
I'd replace it and the PCV ... it may be a blockage in the oil emissions system causing pressure and forcing oil out the seal, the weakest link.
I'd also replace or plug that open hole in the exhaust ...
