    Air conditioning

    What's the best way to have a fairly trouble free ac? Mine has been converted to134 and the compressor was replaced as well, now I see the front seal is starting to leak oil I'm assuming due to the higher pressure that 134 runs at. Does anyone make a newer compressor designed for 134 that bolts in and looks stock? I'm thinking of flushing everything and going back to r12 because the condenser is not designed for 134 either. Anyone have any suguesstions?

    Front compressors seals are designed to leak in that era of GM cars. It seeps to keep the front compressor seal lubricated.

    Check the type of lubricant you used in your system

    Thanks for the replys I know about the oil deal but the problem is I didn't do the 134 conversion it was don when I bought the car, the compressor is a four seasons reman and from my experience they are not the best quality. I'm a mechanic but I have never had very good luck with 134 changeovers in gm, some seem to work ok and others not. I was wondering if someone made a sanden or a new Delphi that would work. Seems like vintage air or someone like them would make a conversion that replaced the compressor and condenser since from what I read those are the main reason that 134 doesn't work like it does in newer cars
