Narrative:
After start of left engine; EICAS displayed 'left engine oil filter.' there were no other abnormal indications. Crew ran checklist on ground procedure; and shut down engine with oil temperature at 79 degrees C and EICAS still displayed. Crew contacted maintenance control and maintenance control directed aircraft back to gate for chip and filter inspections. Back at gate; maintenance found oil filters full of metal and chip detectors with metal attached. Engine was only at half life with 9600 hours since last overhaul; and aircraft had just flown in on the all-nighter from the islands. If this EICAS occurs in-flight; crews are directed to shut down and land at the nearest suitable airport. Our flight was about to go ETOPS! Normally; these engines go to overhaul between 20000-25000 hours.

Title: A B757 FLT CREW EXPERIENCED A 'L ENG OIL FILTER' EICAS MESSAGE AFTER ENG START ON THE GROUND. THEY SHUT DOWN THE ENG AND SUBSEQUENT MAINT EVALUATION FOUND METAL IN THE FILTER.
Narrative: AFTER START OF L ENG; EICAS DISPLAYED 'L ENG OIL FILTER.' THERE WERE NO OTHER ABNORMAL INDICATIONS. CREW RAN CHKLIST ON GND PROC; AND SHUT DOWN ENG WITH OIL TEMP AT 79 DEGS C AND EICAS STILL DISPLAYED. CREW CONTACTED MAINT CTL AND MAINT CTL DIRECTED ACFT BACK TO GATE FOR CHIP AND FILTER INSPECTIONS. BACK AT GATE; MAINT FOUND OIL FILTERS FULL OF METAL AND CHIP DETECTORS WITH METAL ATTACHED. ENG WAS ONLY AT HALF LIFE WITH 9600 HRS SINCE LAST OVERHAUL; AND ACFT HAD JUST FLOWN IN ON THE ALL-NIGHTER FROM THE ISLANDS. IF THIS EICAS OCCURS INFLT; CREWS ARE DIRECTED TO SHUT DOWN AND LAND AT THE NEAREST SUITABLE ARPT. OUR FLT WAS ABOUT TO GO ETOPS! NORMALLY; THESE ENGS GO TO OVERHAUL BTWN 20000-25000 HRS.
