I've already turned it into a "praise the PAP" thread.
thank you for the quick rescue and dowsing, otherwise it would have taken a wrong turn right from the start with all compartments blazing (all pun intended).

From what I gathered so far, the crew did everything correctly and professionally regarding the air turnback. The engine caught fire after the landing and as to why the crew did not evacuate immediately, they must have had their reasons. Lets just wait and see.
Thanks for the clarification. However, there are too versions in the report. "miss lee said there is a fuel leak...". The pilot said that there is oil leak. I understand that engine oil is designed with high flash point and should not burst into flame. However, fuel will catch fire with the slightest spark. So are the seals in the engine so badly damaged that fuel is leaking out and yet the engine can still continue to function? For normal combustion engines that i know the engine will fail first Well I guess only those in the investigation will know the truth.It was an oil leak so there was no need to dump fuel or divert to another airport. The best thing to do is to turn back to where you have the best support in terms of engineering and passenger care which in this case was Singapore.
most likely cockpit crew assessed raging fire in the wings would pose certain danger to evacuating passengers plus the prospect of passengers getting in the way of emergency trucks attempting to dowse the fire. the latter was what happened to ariana airlines at sfo. death was from emergency truck running over passenger lost in the foam.

Thanks again. I have made the assumption that the engine oil must be able to withstand the temperature created by the combustion of the jet fuel even at ground temperature as all planes must land with a hot engine. Otherwise, the engine oil might burn in the engine. Perhaps the cooling system helped to cool the engine oil. But then wouldn't the leaked oil cool faster as it is out of the lubricating system, no longer being recycled and gets heated by the hot engine?The oil can leak in a manner that it collects at the rear end of the engine and pools there. While the plane was in the air, that area is relatively 'cool' due to altitude and whatever cooling factor cause by airflow. On the ground however both these are lost and the temperature of the engine even at that time can be high enough to reach the oil's flashpoint to ignite it.
For a moment, I was hoping a TIONG was on board and seated next to an exit.
He would had opened the door to lit up his cig with the flame on the wing, while the rest of passenger can rush out of plane. This TIONG will be a hero that saved hundreds of passengers and crew, thereby saving all Tiong's reputation worldwide in airlines! Why are they not there when they are needed?

Ah, brilliant engineering feat, using hot engine oil to preheat the fuel and cooling the oil at the same time. However, i am surprised that the aircraft manufacturers didn't take care of the risk of leaked engine oil accumulating at the rear catching fire if there are such precedences.Inflight as the oil cools and lubricates the system it gets heated up, but it is then quickly cooled by a fuel/oil heat exchanger. The cold fuel gets heated by the hot oil so there is less likelihood of freezing, and the hot oil gets cooled by the fuel.
Dealt with efficiently and effectively. This proves beyond doubt just how good the PAP is in dealing with a crisis.
