I could not figure where my leaks where so am sitting here with the professionals
They installed new green o rings on evaporator and on my new drier.
They then pulled 30 inches vacuum and all is perfect.
Except they ran out of R12 here in CA.
So i will add that myself as AC is holding vacuum perfectly.
I had a very peculiar AC leak on the line that goes from compressor to the drier (drier end). That large female threaded nut gauled inside with aluminum and we thought it was tight when in fact it was gauled and would not tighten the O ring on that end. The nut was tight but the AC hose/O ring you could still wiggle and turn. After figuring that out, things went smoothly and we got and held perfect vacuum.
