It is a March P411 compressor, so, I will not take a chance, and I will also order a new one.

The suitcase was cleaned out when the engine bay was painted. In addition, I cleaned it out again, and re-sealed it well when I changed the squirrel cage fan motor. The evaporator looked good. I do not plan to mess with the suitcase.

So the plan is - new March P411 compressor, new parallel flow compressor, new expansion valve, new dryer. Let me know if you have any other recommendations. When I get the parts, I will resurrect this thread so you can follow. Thanks.
I'm going to strongly recommend ditching that POA Eliminator and installing your old rebuilt and recalibrated POA valve. If you don't have the old one, find one. I don't think you will be happy with a cycling system. Every time the compressor cycles off you'll experience a rise in temps from the vent. It's better than nothing, but if you're going all in, then go with the system that will give you all in performance.
