Default Vac,pump oil leak

I have a 1994 350,7.3 and its leaking oil from mount bolt in vacuum pump. I didn't think the engine oil went thru the vac.pump but it is dirty engine oil. The pump started making noise and the pully looks to be running out of line with the other pully's. Oil is dripping from the lower bolt hole. If engine oil doesn't run thru vac.pump, then it must be leaking from the head. The leak is fresh. I guess I will take the pump off and hope the head is not broken. If it is, maybe I can seal it with something. I can't understand how a head would break in such a way.

The vacuum pump has its own oil in it. Not much, but it does. It's on its last few miles. Get one and the pulley pulling/pressing tool now and replace it before it strands you.
