I'm aware of the R4's failings. If I could have easily substituted something better I would have. The repeating pattern of gradual loss of cooling, followed by normal operation the next time I use the AC, seems to indicate some sort of variable valve failure, other than the ones in the compressor, and one part that wasn't replaced is the expansion valve. Is this problem unlikely to be caused by a faulty expansion valve?
I'm not ready to condemn the R4 just yet, at least not until I'm certain it isn't he expansion valve. But if I have to get another compressor, I'm not wasting any more money on R4s. I'll try to rig up something decent, like a Sanden or Nippondenso.
Happy Motoring, Mark
