You do get oil in the shaft as it moves around the system.
Have you changed your crankcase breather?
No bud, seen quite a few posts with people thinking its that, read a post that said run car full dipstick and if oil comes out then breather blocked, mine didn't leak any oil.....dont know how true it is
Not sure if there's a BMW dealer on here selling parts? If there isn't ring your dealer and ask them for a price.Any recommended brand of breather?
Looks excessive to me, had I have seen this post I would have first said what another chap did which was check for shaft play. The next thing would be the crankcase breather, a quick test is to unscrew the oil fill cap with your finger holding it down, release your finger and if theres excessive crankcase pressure you'll see the oil cap bouncing around, if all is well it will have little to no movement.The main problem was that it was dripping onto the driveway but I replaced the breather and the seal so hopefully it will not leak anymore, also there was no oil in the intercooler which I assume is a good sign
