I just experienced this with my 3.0 2003 X5. I am in the process of writing a DYI specifically for the 3.0 as the location and work involved is slightly different than the DIY on the How to tips in this Forum. I am sure you can't wait for me to get done before you start, but if you go to the How To's on the very top of the screen when you are in forum home page(in between Articles and Gallery) http://www.xoutpost.com/newreply.php...ojs=1#tipsmenu select X5 tips and tricks and then scoll down to you see oil seperator DIY. This instruction is very helpfull but I am adding some more information. Anyway good luck contact me if you have questions as I just got done 2 weeks ago.
