VERY STRONG ODOR COMING THROUGH AIRCRAFT THAT SMELLS SLIGHTLY LIKE OIL.  SMELL SEEMS TO BE STRONGER WHEN USING THE COCKPIT PACK.  PLACED ON MEL, REF 49-2.  PRIOR TO RETURNING AIRCRAFT TO SERVICE, TROUBLESHOT TO APU AIR.  GROUND RAN NR 1 AND NR 2 ENGINES AT 85 PERCENT FOR 30 MIN, SMELL CLEARED.  MEL CLEARED ON 4-8-97 BY INSPECTING APU FOR SMOKE SMELL, NO DEFECTS NOTED.  INSPECTED COCKPIT PACK, CHECKS GOOD.  INSPECTED CABIN PACK, FOUND ACM TO BE OVERSERVICED.  ADJUSTED OIL LEVEL IN ACM, AND REPLACED WATER SOCK.
