One of these days I am going to correctly diagnose one of these internet service calls.
Jp, is SST suction superheat temp and SCT subcool temp ?

I doubt the 325 head pressure by itself, would have caused the compressor to overheat (unless the outdoor coil was restricted), so the superheat was probably high initially. And the fact the head was high could suggest someone before you had overcharged the system, in an attempt to get the superheat lower.
If additional refrigerant raises pressures but doesn't decrease superheat, I'm thinking distributor tube restriction, which is a thin theory. But I've never seen an unrestricted fixed metering system that wouldn't eventually load up the coil, if you add enough refrigerant.
Disable the blower motor with the condenser running and see how the coil loading goes.
So, what did you have to do to fix it?
