When I overhauled my engine last year I removed the compressor and drained most of the mineral oil out of it. I put new seals on and drew a vacuum on the system and it held fine. However, I didn't charge it and left it as is. Now, assuming my compressor is still good, I want to flush the rest of the mineral oil out of the system including the evap and condensor coils. I'll replace the drier assembly. What can I use as a solvent to flush with, and will it evaporate out of the system with a compressed air purge? I've got access to shop air at all the CFM I would want. The system is R12, I'm converting to R-134A.
Thanks!
