E30 M20 water pump

   Carefully using a mechanic's stethoscope, you can "home-in" on the 
origin of the sound.  If it is the water pump, have it changed 
immediately.
   If the bearings totally fail it can also damage your radiator.
   Sudden coolant loss will damage the motor.
   A tow home is much more than the cost of the pump.
   Unless you can document that the timing belt has been changed 
within the two years or 25k miles, have it changed along with the 
pump.
   The pump housing is the "bump-stop" for the timing belt tensioner, 
and the belt has to be moved out of the way in order to replace the 
pump.
   It's silly to not also replace the $25 belt (and tensioner) while 
you've already done 90% of the labor.
