Late entry.

Rogers Machinery technicians showed up Tuesday with the components to fix the leak on the compressor.  The intercooler and aftercooler assemblies were removed, cooling lines on both components were cleaned and inspected, all sealing surfaces were inspected and cleaned, then the system was reassembled and tested, technicians reported no issues.  The compressor is back to usable form.  The dry air system was turned on and left running for 1 hour, after the hour I measure a dew point of -41.7 ^oC right before the pressure regulator.
Note, the compressor needs a yearly maintenance done, but can't be completed right now because we are waiting on a back order kit, perhaps by December.
