I am continuing the monitoring of water drips.
So far so good. If it was the O-ring, maybe it had a bad hair day and resumed its duty.
I know that is pipe dream material so everybody's tips will serve me well if and when I end up having the pump replaced with all the other stuff.
Car (1998 300SE) has about 136K miles on it......
Update feb 5-08 had mechanic replace water pump.
