i know a very good porsche mechanic that did nothing to his r12 sytem in his 930 except fix the leak/s and charge with 134. this was more than 5 years ago and it is still working fine.

if a system needs a charge, there is a reason, it leaks. finding the leak is the hard part. you could put some dye in there and put in a can or 2 of 134. if you cant find the leak, chances are it is the evaporator. replace the expasion valve if you have to get in there for that.

if it was me, i would putr12 back in there. you can get it on ebay. i have a few cans still from when i bought some on ebay. the only thing i have left with r12 is my truck, but that has a bad metal line and i cant seem to find another one. i was going to put the ac back in the 911 but since i have been driving the 325, (COLD AC) i dont think i will.

you could also put dye in and charge it with nitrogen.

milt, ithink that $200 recharge is just that. pull out the old, perhaps a flush and charge with 134.
