Just from reading the boys in the 4.8is thread, there was someone who posted that the valve stem seal problem comes from the fact that BMW would recommend up to 15k miles before first oil change, and that first lengthy interval led to the smoking problem that let oil past the seals. I'll have to go into the "blue smoke at extended idle" thread to find it, I have M54 so I'm not familiar personally from those issues. Regardless, I do my oil/filter changes yearly or at around 7500 miles, whichever comes first (for me, its always yearly, I don't drive that many miles a year LOL). And if I had a brand new 4.8is engine coming my way you better believe I'd be doing that kind of interval, heck some members here change it every 5k, although I think that is overkill.
