Bluebee, nice modification to the dipstick tube.
How many people encounter the snotty oil build up? The reason I ask, I live in a colder climate (Central Ohio), my car is from Pittsburgh, and the original non-cold weather CCV was "snot free" and the double-walled dipstick tube was clear @ 212k. The car is driven all year and sits outside...
I like coffee.
My e39 is fixed and moving towards atrophy.
