Right crankcase cover water pump housing corrosion.

Hey!

Upon finally cleaning up the right crankcase cover, the water pump housing area looks pretty corroded.

I don't think much can be done to the surfaces that mate with any of the seals. I suppose I could hit the walls nearest the impellar with a Dremel to church it up, but was having any cooling issues prior, other than the rouge coolant drip fromthe weep hole.

What say ye?

Crankcase covers show up on Yahoo Auction here in Japan occasionally. Is it so bad you'd grab another?
