Thanks. I replaced all the o-rings but unfortunately with OEM o-rings after I flushed all the lines but used r134 oil to lube them. I will be having Bernie rebuild my compressor for r134. I also replaced the evap and switch and removed the STV (attached to the condenser?) and flushed out the condenser. So based on this I will need to replace the o-rings with green ones and should be ok?
