The leak definitely is not antifreeze. (yes I'm running with Zerex G-05). The leak has gotton progressively worse and it is a clear oily substance. Today the AC stopped blowing cold. It appears to be coming from the area where the two hoses are mounted to the back of the compressor with some type of bracket and and a bolt holding them into their connection. I suspect there is are O rings involved. Could this be AC oil? Anyone know if there are O rings in this connection and can they be replaced? If there is a leak in the AC system I suspect this is it. The dye sounds like a good idea. Can this be purchased at an auto parts store?

The system has been converted to R134 and I just recharged it two weeks age to get it blowing cold.

Thanks,
Gene
