Hi,
I finally replaced every leaking component and seal in my AC system, 1999 XJ R134. Anyway, it now holds good vacuum. So, I vaccuumed it out to -29, waited a half hour, then dumped in 2 cans with... 11oz refrigerant, 2.5 oz PAG, 1 oz. "cool down additive" and a red dye. I replaced the accumulator and condenser and all hoses, so I figured I probably lost more like 4 oz than 5, but I figured it would be fine.
Now, it works. But, at full blast cooling, it gets pressures of 50 low, ~320-340 high. This seems insane. It was around 90 degrees F as I charged it. The low side line is sweating like crazy, and the high side line is too hot to touch. The compressor is also being loud, i believe as a consequence. The thing says it takes 1.25 lbs of r134, and I put in 22 oz. Could this extra 2 ounces plus a possibly slightly diminished system capacity due to the extra oil be causing these issues? I am delighted that it works and is fairly cold, but the noise from the compressor is incredibly annoying and Im worried for the health of my system. Can anyone help me out here?
