Charlie,
Before you tear the pan off try the below. I got a low mileage 230 and found zero oil pressure until I did the below as a lark before puling my oil pan. It only takes a few minutes to try anmd it may save you lots of time/frustration later.
forward from old post . . .
My experience has shown that new 230's need the oil pump primed from above to develop oil pressure. [This is not in any manual] To prime it, first, remove the line fitting connecting the oil galley to the oil pressure sending unit, second, loosen the oil pressure sender unit bracket screw so you can wiggle the bracket up with sender and/or remove the sending unit. Third, pour about 3 oz of 10w30 oil down the metal oil pressure pipe going from the oil. Do it slowly b/c it will bubble alot since the galley is dry and full of air. Keep adding more until the line won't take any more.
Fourth, pull all spark plugs to reduce engine fruction when spinning it. Fifth, spray thin oil into cylinders - not to much! Spin engine by hand and listen for gurgling sounds from oil pump. Sixth, add more oil down oil line to replenish that went into oil pump. Seventh, DO NOT STARE DOWN LINE LINE AFTER A TINY BIT OF OIL PUMPS OUT - it will blast you (I did't care - I was so happy to get oil pressure:) Eight, install oil pressure sender. Nine, spin engine using starter motor to prime engine and blow out oil from cylinders. And Finally, reinstall spark plags and listen the the engine run( hopefully - but that's another matter).
Good luck.
