Another update & question. I got that discharge pipe fitting welded, and it no longer leaks from there. But the system still won't maintain a vacuum for more than an hour or so - vacuum drops from 30 inHg to about 25~26 inHg in that time. A very slow leak, so I put a partial charge of refrigerant in the system and went hunting for gas leakage again with the electronic sniffer - looks like it's coming from the compressor shaft seal as best as I can tell.
Compressor on this car is a Nippon Denso TV14C, according to the tag on it. Does anyone know if a rebuild/seal kit is available anywhere for this compressor? The Mazda shop manual has pretty good instructions on doing the rebuild, so I can tackle that myself if I can get all the necessary replacement parts.
