Not sure everything you wrote applies to my car because you mention pressure readings and I've not made any.

I checked my records and saw that in May, 2001 I had a new compressor installed by a reputable AC specialist. At that time, 2# of R134a was serviced and a conversion kit was installed. A sticker was attached under the hood stating the retrofit was done according to SAE J1661. The mileage then was about 107,000. Some years later, at 214,000 miles, I received an estimate for a new compressor which I opted not to get at that time and after driving another 6,000 miles and not driving at all for four years I'm now finally ready to fix the AC. Do you think any of your previous comments are affected by these facts? I can't seem to find any copies of SAE J1661 online, but I did see more than one version exists and the latest is dated 10 years after my car was retrofitted. The version prior was a year and a half before my car was done.
