## Discrepancy

DURING CRUISE NR 4 ENG OIL PRESS LIGHT CAME ON, NO OTHER SYSTEM MALFUNCTION NOTED, RAN CHECKLIST.  LIGHT WENT OUT BUT LATER CAME ON INTERMITTENTLY, DIVERTED TO JFK.  REPLACED LOW OIL AND DIFF PRESS SWITCHES, NO HELP.  SAME OCCUPANCY NEXT FLIGHT, TIGHTENED TERMINALS ON LIGHT ASSY MOD.  SYSTEM DEFERRED AND REQUIRES FURTHER TROUBLESHOOTING.
