Tiny black dots in compressor oil drain

Year: 2002
Make: Mitsubishi
Model: Lancer
Engine Size: 2.0 L
Refrigerant Type: i134a
Country of Origin: Japan

I removed compressor from the car. Drained the oil from the compressor. I see a few tiny black specks but no sludge or even aluminum shavings. If I replace the compressor, should I flush components and replace the dryer?

These 'black' dots could be the coating for the scrolls within the compressor. This would be indicative of internal compressor damage. Strongly suggest the replacement of the condenser, TXV, flush the evap and hose assemblies. Insure the system is properly recharged. The presence of any contamination within the system must be removed. Since the condenser installed in this vehicle has extremely small flow orifices and the flow pattern it is almost impossible to adequately clean to insure proper functionally.
