The was nothing of a check valve in the pump, I think somebody removed it at some point. Is it normal to have oil in the pump? Will the rebuild solve that problem or is it something to worry about?

This is strange, I would have thought that, if there is no check valve, the vacuum pump would not pull ANY vacuum! (at idle, or otherwise.)

No, it's not normal. But the absence of the inline check valve might explain the oil being sucked into the pump (from residual vacuum in the system) when the engine was off.
In addition to the pump rebuild, you need to renew the check valve.

Vacuum woes continue

Well, I got my rebuild kit for the vacuum pump and changed out the parts. Reinstalled and was all ready for some real vacuum pressure, but now I have none. What could I have done wrong. Does it take some kind of breakin, probably not. Anyway, I fill really whipped on this right now. It looked so straight forward. Suggestions would be greatly appreciated.
