MLG TOLD OF SMOKE COMING FROM ENG AS THEY TAXI TO GATE.

Narrative

AFTER LNDG IN BTR; GND RPTED SMOKE TRAILING FROM OUR #2 ENG. COCKPIT INST REVEALED NO UNUSUAL INDICATIONS. WE WERE PUZZLED BY THE CALL BECAUSE WE HAD ALREADY SHUT DOWN #2 ENG AS PER COMPANY POLICY. AS WE APCHED THE GATE; THE GND CTLR RPTED SMOKE COMING FROM THE L ENG AND THAT SMOKE WAS INTENSIFYING. AS WE APCHED THE GATE; THE EGT ON THE #1 ENG BEGAN TO INCREASE; APCHING THE GND IDLE LIMIT. SINCE WE WERE ONLY ABOUT 15 FT FROM THE GATE; THE CAPT ELECTED TO SHUT DOWN THE L ENG AND SWITCHED ON EMER PWR; THUS ENSURING WE HAD RADIO CONTACT. AFTER COMPLETING THE SHUTDOWN CHKLISTS; THE CAPT DIRECTED ME TO VISUALLY INSPECT THE #1 ENG. IT WAS SMOKING EXTENSIVELY FROM BOTH THE FRONT AND BACK. THE FIRE CHIEF WAS ON SCENE AND ASKED ME IF I WANTED THE FIRE TRUCKS TO RESPOND. ALTHOUGH THERE WAS NO INDICATION OF FIRE OR CONTINUED PROB; I ELECTED TO HAVE THE FIRE TRUCKS RESPOND. I BELIEVED THAT IT WOULD BE SAFER TO HAVE THE TRUCKS IN THE AREA -- BETTER TO ERR ON THE SAFE SIDE. THERE WAS NO EMER EVAC AND NO FURTHER INCIDENT. THE PROB TURNED OUT TO BE A FAILURE OF THE #6 BEARING -- DUMPING OIL INTO THE HOT SECTION OF THE ENG.
