Oil Priming

I HAVE READ QUITE A BIT OF DISCUSSION ON THIS SITE ABOUT THE NECESSITY OF PRIMING THE OIL FILTER HOUSING IN THE COURSE OF PERFORMING AN OIL & FILTER CHANGE ON V8 CARS. ALL OF MY PREVIOUS BENZES HAVE BEEN STRAIGHT AND V SIXES AND THEREFORE I HAVE NEVER TAKEN THIS ADDITIONAL STEP. I NOW OWN A 99 S500 (W140, 119 ENGINE). I HAVE DONE TWO OIL AND FILTER CHANGES WITHOUT PRIMING AND HAVE NOT NOTICED ANY PROBLEMS. OIL PRESSURE RISES WITHIN 3-5 SECONDS UPON STARTING. I WOULD LIKE FEEDBACK ON WETHER PRIMING IS NECESSARY ON THE 119 ENGINE OR DOES THIS STEP ONLY APPLY TO OLDER BENZ V8 ENGINES? AM I RISKING ANY INTERNAL DAMAGE TO BEARINGS, CAMS, OR ANYTHING ELSE BY NOT PRIMING? IF YOU ARE A BENZ MECHANIC, PLEASE TELL ME WHAT YOUR PERSONAL PRACTICES INCLUDE REGARDING OIL AND FILTER CHANGES WITH THIS ENGINE.
