i ordered a brand new oilpump from bmw...
the plan is to polish the oilpump-case and every part of the oilpump and round every edge..!to lower the friction and improve the flow of the oil.. after that perhaps i send the parts for lowfrictioncoating..!!

Maybe you can send the plunger to be coated with Moly or some other low friction coating. It seems like this part tends to wear.

Far as I know, MM is using a stock pump.

As for the broken one I can assure you, something got into that pump. Just looking at a few nicks in it tells you that. Mine was exactly the same way. Nothing is wrong with the stock pump as far as I know, just a poor oiling system built into the block.

I would rather coat the pump housing than the pump itself, being that it is aluminum and therefore more prone to wear.
