I have only heard that this works, but have never tried it or known anyone that tried it, so it's really just a rumor.
Pressurize a freezer dry system with the environmentally friendly refrigerant, turn off the light and using a black light, the leaks fluoresce. I'm sure this is also available as some form of leak detector without the fluorocarbons. http://www.labino.com/appl-leak.html Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

Before that, as long as the compressor could keep up (running non-stop), it must have been ok.
