vac pump spewing oil

[clarknova]

grr. just when I had nailed down the glow plug issues and gotten running again...
the vacuum pump is leaking oil around the gasket. ok. no big deal, just need a new gasket, right?
but wait, there's more!
it appears that the vacuum pump has diligently been pumping not air into the air cleaner, but, that's right, OIL into my air cleaner and intake...
I have not had enough free time to open the darn thing up, but I wonder if anyone knows exactly what I need to do so I might expedite this repair in an efficient and proper manner. I see a repair kit and gasket from Fastlane in my future...
