## Discrepancy

EN ROUTE IAH-LAX, THE NR 4 ENGINE WAS SHUTDOWN DUE TO OIL FILTER BYPASS LIGHT, RISING OIL TEMPERATURE AND DECREASING OIL QUANTITY.  CREW FOLLOWED COCKPIT OPERATING MANUAL AND RETURNED FLIGHT TO IAH WITHOUT FURTHER INCIDENTS.  MAINTENANCE REPLACED THE NR 4 ENGINE AND TEST WAS NORMAL.
