Flushing needed?

Refrigerant Type: 134A

I am awaiting parts from AMA and contemplating a game plan. New compressor, acumulator, o-ring kit and blue orifice tube. Compressor did not fail but was leaking. Shaft seal was replaced once years ago so I decided to go with the new unit. Since the compressor didn't actually fail, I don't expect a huge problem with debris. My main concern at this point is the oil issue. After doing a lot of reading here, I am planing to use 100 ester oil. So my question is should the condenser and evaporator be flushed of all oil while the system is opened? If not, how much oil should be added? OE Specs call for 8oz PAG150 .

Thanks, Jim

If you don't have any signs of debris. Blow out all the components you are not replacing with shop air to remove waste oil. I would prefer you blew it out with nitrogen if possible. Add back the OEM specifications at that point.

Thanks, That's what I was thinking. I'll see what it looks like when I open it as far as the screen on the tube and what the oil looks like.
