Gents I have a 63 Riviera that has leaks in the STV. I put in the STV upgrade kit that cycles the compressor clutch electronically. The STV has not worked since I started the project. I figured if I skip trying to get the STV TO work like it was designed id be ahead. I put in the second STV up date kit and STV LEAKS badly. Do I use an O ring every fitting? I was thing about getting the STV by pass kit instead of suffering with the STV that prone to leaks. Any suggestions? Turbinator
