Made this a while back. Tend to get people asking me if it worked. Short answer is no. Little background on what I've done so far.
1. Swapped compressor and had some new lines made. Vacuumed, oiled and charged system myself. Ice cold. Only started the car once or twice a week. After 2 weeks, the pressure had dropped enough to not kick the compressor on.
2. Swapped out condenser for Vintage Air 14x20 unit cause the old one appeared to have a leak and new lines made to fit condenser. Again vacuumed, oiled and charged the system myself. Ice cold again. Same result, after 2 weeks, pressure had dropped.
The leak is tiny and appears to exist when the system is pressurized. Tried to locate it with UV but no luck. I've vacuumed the system for an hour, sealed the system and waited until the next day. No change in the vacuum reading.
Only thing left to replace is the auto zone low side r134 adapter fitting with a proper weld-in fitting to determine if that's the tiny leak. If not, the evaporator will be the only thing left that I have not replaced. Everything else is new. If it ends up working, I'll most likely update my thread.
Good luck and if you find a solution, please post it up. Us people in the heat NEED a/c.
