RW> That's because they never disconnect the compressor when they do engine

   I do know they had to evacuate the A/C system when they did the swap.  They   
   had to re-mount the compressor to the new engine.  I assumed they removed the   
   compressor, but kept all the lines in tact.   
      
   That doesn't appear to be where the leak is.  From what I have seen so far, it   
   looks to be in a line off the compressor that meets at a junction point.  The   
   black light "glows" in a circle around the tube that enters into the junction.   
   (near where the radiator filling area is located).
