Some say the R-134A is rough on compressors.... I've heard they'll last a while, but eventually start rattling and go bad......... Then there is a friend that claims he let the R-12 out (Don't tell EPA) and put R-134A back in.. 4 years ago, no problem!
I think if I was in your situation, I would remove each individual componet, flush the R-12 refrigerant oil out with lacquer thinner or mineral spirits, blow out with an air hose, re-install with correct ester (R-134A compatable) refrigerant oil, replace filter/dryer, evacuate and recharge with the R-134A. You use 80% R-134A to what your system calls for in R-12
Required tools for operating a Vintage Mustang:
1. Duct Tape
2. J.B. Weld
3. B.F.H. (Big Fat Hammer)
4. VINTAGE MUSTANG FORUMS II
