Well I pulled the freon the other day and replaced the orfice tube. Did'nt see anything wrong with the one I pulled. Pulled a good vaccum and started putting new 134 in. System holds 3.8 pounds. By the time I had just 3 cans in (36 ounces) suction pressure was upto 50 psi.

Both the rear suction line and the front are getting cold and sweating when system is running high rpm's. I think it has to be bad valves in compressor. Could the accumulator cause this problem?
