4 engine widebody transport crew suspected a bird strike on #3 engine during takeoff lax, destination nrt. The engine slowly lost all of its oil and it was shut down as a precaution. The winds were bad at anc and being well west of it, the crew elected to proceed to nrt and restart the engine for approach and landing which they did successfully. There had indeed been a bird strike.

Narrative:
Suspected bird strike #3 engine on takeoff lax. Engine had noticeable vibration, and slow oil quantity loss. Oil quantity decreased to 0, and engine was precautionarily shut down at XX48Z. Planned to restart engine and use for approach at nrt, japan. Engine was started during descent and normal landing made at nrt. Found damage to engine due to bird strike on takeoff at lax. Supplemental information from acn 358974: wind 010 degrees at 20 KTS gusting to 27 KTS, peak gust 47 KTS, opted to avoid anc and continue to nrt for operational safety. During entire event #3 engine had normal oil pressure, temperature, and engine EPR, egt, N1, N2, all normal.
