On a 2.0L the MPS hooks up to the air intake by way of a vertically (pointing up) mounted vac port near the TB. The MPS has no vaccuum of its own, I can't see how the oil was sucked into it.

Only thing I can think of, WAG, is that you either had the MPS hooked up lower in the air intake and the NPS was mounted low in the engine bay. Some how oil came into the MPS vac line and dripped into the MPS. Either that or at an oil change someone spilled oil into the two slits in the MPS.

Which side of the diaphram was the oil on? The side with the slits (to measure the barometric pressure) also has the adjustment screw. The other (sealed) side has the "two flying sausers making love" type of thing.
