Sorry to hear about your problems. I found out about the plastic waterpump on this board about 6 months ago and my 95 525I with 70k miles and original pump was a prime candidate for disaster.
I changed the pump ($40) and yes it was plastic and yes it had small cracks in it. This is the easiest waterpump job you will ever do and is not to be put off. This board saved me money and I will be forever greatfull to all who post information here.
Check those archives...they're full of great information
