Threads like this are what makes shop forum great. Thanks guys.

Now I have a question. It seems that the R4s are dogs, especially if they are only lasting 1 1/2 years. Do any of you AC guys have a durable compressor that you can recommend for a W123 turbo? I have two wagons, one of which blows cold and one that does not. I have not diagnosed the bad one, but don't want to do all the work just to have the compressor fail in a couple of years.

I know that the R6's and York piston are solid units but I think they will never fit. Has anyone put a different compressor than the R4 in a W123 turbo?
