The dual action pump is on the non-manifold (driver) side of the engine, centered front to back, and is mounted several inches above the oil pan. It's actuated by a horizontal pushrod from the camshaft which is on the far side of the engine. I've not personally experienced the situation where the vacuum diaphram has a rupture and allows oil to be drawn into the intake, but I'd not rule it out as a possibility. The vacuum line from the intake manifold is attached on the rear portion of the manifold and runs horizontally behind the engine block to the approximate location of the starter motor where the connections are made to the brake booster, Bijur lubricator, wipers, and the connection to the booster pump. I'd disconnect the line at the booster pump and plug it off with a golf tee or similar and see if the problem clears up.

Pump kits are readily available, it's an AC #494 pump.
