That tan pasty residue (milkshake) can also be a result of excessive water vapor in your crankcase, which can be caused by a worn o-ring on the dipstick. When the engine cools after being run, it pulls cooler air containing moisture into the dipstick tube and crankcase and you get churn the next time you drive the car. I get this on my Volvo 850 and my wife's S40.
