I don't recall hearing anyone who posted about a rear main seal leak, although I'm sure that can happen.

The CCV parts can be bought from a discounting BMW dealer for under $150. Several have kits where they've put the parts together. Replacement is involved, but doable for the home mechanic. Here's the DIY I used:
Is a CCV the same as a PCV? Mine just drips a drop maybe two when driven then parked.
It doesnt keep running out over time. Wow looked at that DIY...I am not near that mechanically inclined.
Oil change, brakes, minor stuff yeah. LoL
