Question about Heating & Cooling
I'm guessing you should have 3/8 & 5/8 copper on that unit with a maximum of 50 feet. I doubt the line set size is affecting your pressures that significantly, you likely have a leak.

Your suction pressure is erratic, your max. pressure is to much high. You did not measure your unit current reading liquid line press. to complete the data. But the problem of your unit is not the compressor its the system. Try to reprocess the system flush the unit with nitrogen, isolate the capillary tube and flush it with nitrogen to insure that no restriction.

Exactly how much refrigerant did you charge into the system when you recharged it? If the suction pressure is varying that much you most likely over charged the system and got a liquid flood back which took out the compressor valves.

SOURCE: AIR CONDITIONER IS NOT COOLING,
there is probably a leak in the systems somewhere, it needs to be inspected for a leak and charged with R-22 for proper cooling.
There is a stop leak for air conditioning systems available to licensed technicians to buy, might work if the leak is very small.

try to throw cool water on the condencer front of the engine radiator and see whether any cool air comes in the car. If so see whether the pressure valve is working okey or not because might the pressure is not sufficient.
