Jooseppi: You haven't mentioned the parts of this story in which you flush the entire system completely, replace all seals, and only then recharge with 134a... (!!)
By 'can' of R134a, I hope you mean one containing the
couple of pounds of 134a you'd need for a complete recharge. It's best to recharge these systems by weight of refrigerant, from my understanding.
FWIW, my 83 300SD was converted to R134a about 15 years ago, and worked fine. Probably never as cold as theoretically possible with R12, but quite good. It developed a slow leak last year, and the compressor clutch died a month ago. Have now embarked on the complete Flush, Re-seal, Compressor Replacement, Recharge process!
