Oil leaks? Perhaps talking about the number 3 bearing, an issue that was sorted along time ago, or so I was aware. As for electrical faults Im not really aware of a common major issue with them.
With regards operating on icy runways Im not sure if this applies to your situation, as I thought Indonesia was quite a warm place all year round, but I dont know many jet aircraft that stop quicker with or without thrust reversers.
As WOTME said the wing tank corrosion can be bad, and if you look in the manual (not got one to hand) you will more than likely find Indonesia will be in the high risk area.
