Cr, that is great that you used what I have been preaching ( and is approved by the EPA as a test method which allows the venting of that test load ). I am trying to figure out how to divide my 15 oz can of R22 evenly without an accurate scale.
I believe that people can pretty much do whatever they want with THEIR cars... although I do promote following the EPA rules... but when it comes to promoting junk procedures or junk refrigerants or lazy methods... I believe the people on the forum not yet familiar with what is safe and long lasting need to be warned...
If Larry's post was a rant... it had ten years of provocation by some real gems of trollers and bad physics promoters behind it....

Since I caught the new compressor leak before loosing the R12, it was not necessary to replace the drier and flush. However, I don't know how much oil I lost with the leak. I added more oil with the second compressor but I only hope I have the right amount in circulation. I'm trying to figure out a method to sample what's in circulation and determine the oil concentration - should be doable.
Leathermang is another of those type #3 posters that I read carefully. Maybe I can payback with the R22 issue. I didn't have a can of R22. I drove to my favorite AC tech that services my home R22 unit. He added (by weight) the 2 oz of R22 (didn't even charge me), then I drove home and added the nitrogen.
