The Vacuum pulls things towards the Vacuum Pump.
In order for the Vacuum Pump to push Oil in the opposite direction I believe there would be obvious lack of vacuum issues would show up.
But, that is on Piston or the newer Van type Vacuum Pumps.
Vacuum Pumps with a Diaphragm could be different but I think there still would be symptoms of a vacuum loss issues.
