Is it ok to reconvert back to R12 from R134a?
Recently I had a r134a conversion done on a 92 SC400 I just bought. Since then I've been having problems with either my engine or compressor skipping. After doing some research on the board it seems that others have had similar or other problems after doing the conversion. Would it be ok for me to switch back to R12? The o-rings were not changed during the first conversion so would it be just a matter of evacuating the system of r134a, changing the oil and dryer, and removing the r134a port? Thanks.

Did you just do one of those quick fill kits and not change anything? If so just drain it and go into a friendly shop and say your A/C is dead. There is no way that if your car came with an R12 system it would be illegal to put R12 back into it. While you are supposed to fix the problem I know dealers that will fill a pound for about $80, one friendly "guarenteed it wouldn't take more than a pound, wink".
Last 2 cans of R12 I bought this past summer were about $25 bucks each for my Integra, I just used 1 since I'm gonna sell it.
I was going to do the 134 conversion until I read up on the problems it causes. Bottom line is if you plan on keeping the car it is cost effective to have your R12 system repaired and charged for $200-300 rather than keep throwing money at a bad 134 conversion. To do these right you are going to need to spend money anyway and the fixed R12 system should hold a charge for years anyway.
I don't advocate mass R12 "pollution" but I don't follow stupidity like a lemming either. Look at the regs. other countries are bound to on this subject. The big, rich USA (well, the citizen's with old cars) is shouldering alot of the $$$ due to economics.
