First thing I noticed about the oil change is the cover on the countershaft sprocket needs to be removed. I'm going to get real tired of that. So while I had it off I used the trusty Dremel to extend the cut-out. You'll need an 8mm wobbly socket for this to work. Not a huge deal but I figured it may save someone a little time. Time you can spend cleaning the oil off of EVERYTHING because it goes EVERYWHERE tada!
Try this to keep the oil off everything http://www.cafehusky.com/threads/bmw-oil-filter-kit-comes-with-everything-but-oil.32598/#post-328285 Of course, you probably need to remove the countershaft cover.
