Vintage Air System not too cool????!!!!

lpThe VA kit has an expansion valve on the unit itself. The lines do/are as described, hot for the #6 and #8 and cold for the #10 and the expansion valve gets cold, condensation on the #10 fittings. The compressor cam with assy. lube so I had to drain all I could into a cup, marked the level, and refilled with pag oil to said mark, and put that amount back in the compressor. The compressor was not bought from VA cause they wanted way too much $$, so I got it elsewhere,(sanden 508). Now it's possible that it could need some more oil...that hasn't crossed my mind.
