OMG I almost shouldn't post this but it's just too funny or ridiculous to
NOT rat on myself.
Not thinking (like I normally do) I was effing around with the rocker arms not knowing what provided the shaft it's excellent and smooth operation until I took the shaft out at which several dozen needle bearings poured out onto my lap and floor (carpet)! Duhh, :-? After getting them picked up and packed back in, I noticed that I was missing one. After two days of scouring the floor and not finding the missing bearing I called BMW to see if I could order just one bearing. They were happy to help and I now have one on it's way to me.... after paying $35!

For one bearing!
I sometimes even amuse myself how fast I throw my money away!
DISCLAIMER: I research how many bearing go into the rocker arm assembly on Skowbum's site and am certain I am missing one because of the larger gap where what looks like two would fit but in reality just one will. Also on his site I read about the different types of needle bearings and so I am sure I ordered the right part.
