If there is too much oil in the system, unequalled oil between compressors (if multi compressor circuit) or liquid refrigerant "lifting" the oil from the sump, a compressor might be forced to try and "pump" oil.

As the oil can't be compressed something would have to give. Smashed up valves, snapped rods, disintegrated scrolls and so on is all likely results.


Why the question?
