Charging a/c in 1982 ???

[gr8vet]

System has been flushed and running for three years r134. It just does not cool as well as it should and I thought about checking the orifice tube, maybe stopped up. If I open the system at this point only; Do I need to change the accumulator? Add anymore oil? Just pull vacuum again and then charge?

thanks

EVERY R12 conversion to 134 has a slo leak, nature of the beast....too many cars, too many years, too many attempts to fix, and never any indication of any leaks.....I blame the compressor seals on the input shaft...no where else to go with it.....I just add a can/year seems to be the typical amount.....but I do have to say the '72 vette has been good for the last several years....

but it has a serp drive with a '88 compressor....
