i cant find the combination of the 3 oils to open the gate. In watches keep. can any one help

Look on the floor. There should be two rows of three circles on the map, they represent the torches and the colour of the oil in each of them.
IIRC, they should be in the rooms directly NW and SE of the one with the machine.
