Check your turbo oil return lines. N63 have issues with coking up the lines. Once they are blocked, oil has nowhere to go but into intake/exhaust. Easy way to check is to pull off the air cleaner assembly off one of the turbos. If it's wet with oil inside, your lines are clogged. It happened on mine and was burning a quart ever 200 miles!
