From what I have seen of them, oil pumps seem to live forever.  Before you
pull the pump, you could try lapping the pump cover.  The cover might have some
grooves worn into its inner face from the action of the pump impellers.  While
a lapping plate is nice to use, you do not need anything elaborate for the
lapping other than a dead flat surface to work against.  A machine tool table
with some wet-or-dry abrasive stuck to it will work.  Even a piece of plate
glass, the thicker the better, and some valve grinding compound will get you to
where you want to be.

PS - Speaking of junk aftermarket parts: The one time I bought a replacement
VW oil pump almost ended in a disaster.  After I had picked up the pump, I was
stuck in traffic.  The only book in the car was Last Exit to Brooklyn and
since I didn't fell like becoming depressed, I decided to take a look at the oil
pump instead of reading.  I pulled the pump from its box and as I turned it
over in my hands, I almost shit whenever I peered down into one of its ports and
saw it completely sealed off by casting flash.  As I probably would have
popped it in without a second glance whenever I got home, I thanked the Good Lord
most fervently for that traffic jam.
