I cant work it out. There is a black hose on either side of the engine behind the timing belt cover but in front of the intake collectors. They stick out either side of the engine below the throttle bodies and look like they go into some kind of reservoir or something right behind where the intake camshaft sprockets are. I've read through the nissan service manual but I cant work out what they're for. I have a pretty good feeling that they're oil supply lines for the timing belt sprockets or something, but I dont want to connect anything up that i shouldn't..
Could they be related to the turbos? Are they coolant lines for the throttle bodies? Can anyone help me out here!?
Thanks,
