the one with the 3 way silicone is coolant. the one at the bottom thats under the turbo that goes down is turbo oil return id have to go outside and take a look which ones which i cannot remember
the two that are metal are both coolant lines, one in and the other out. the black one which is a covered braided line is the line bringing oil into the turbo and the oil return line is at the base of the turbo
