Narrative: At 400 AGL on climbout I noticed an eng oil temp EICAS message. I then got the QRH in hand ready to be read to the Captain. At this time the oil temp was in the caution range. The checklist directed us to retard the throttle slowly until the oil temp returned to normal. It did not; rather the oil temp was now in the red range. The checklist then directed us to [place the] fuel control switch to cut off. Once the engine was shut down the temp steadily decreased. The Captain then declared an emergency and he advised ATC that we would need to jettison fuel. ATC cleared us to an intersection to hold and dump fuel. However a Level 3 cell was over the intersection; so the captain then requested holding further south to avoid weather. The fuel jettison checklist was commenced and jettison lasted approximately 30 minutes. Dispatch was contacted and advised of our intention to return. The Captain advised the Lead Flight Attendant of our situation and told her not to prep the cabin for an evacuation. Passengers were then notified of our situation. Once at max landing weight; we prepared for an ILS approach. The approach and landing were executed and concluded uneventfully. Fire and rescue followed the airplane to the gate and no abnormalities were noted.


Second narrative: Shortly after rotation the EICAS displayed Engine 1 oil temp; at that point I engaged autopilot. The Captain acknowledged and at that time the Relief Pilot was looking up the problem in the QRH. Following the QRH we reduced power on Engine 1 eventually to flight idle with no change in temperature which was as I recall around 179 still in yellow band then a few minutes passed and now was into the red 181-183 temp range. It was at that point the QRH directed us to shut down the engine. Now we were focused on a return; again following the QRH we dumped fuel to max landing weight and went through the Engine Out Approach procedures. During all of this we eventually declared an emergency more so because ATC seemed to handle it better and we thought it best. After fuel dumping was complete we commenced the approach. The event in summary was handled with no problems.


Synopsis: B747 flight crew experiences high engine oil temperature shortly after takeoff. The temperature continues to rise; the engine is shut down; fuel is dumped and the flight returns to the departure airport.
