Don't forget the external inlet is just a a contection to the housing.
The pump sucks in the air from inside the housing.
So the motor and its windings are fully exposured to the oil from the sump.
I don't think it could fill up past the internal inlet to the compressor.
The outlet is connected from the compesssor via an internal pipe to the
external outlet
A tleast on the big AC and fridge units I have cut open. Angle grinder and
time.

Only half the ones I have picked up worked. But then given they are free!

Incidentally the oil getting sucked in with the air has a very desirable
effect of increasing the compression ratio.
