That was one of my first thoughts as well but the water line to feed the turbo comes from a port on top of the intake manifold. It looks like coolant in the picture but seems to actually be some sort of clear glue or sealant that is around the valve (it doesn't look green in person, I think the reflection from the camera flash gave it that tint in the picture). I'm pretty sure it deals with vacuum or oil as well but I can't for the life of me figure out where it goes. This engine came from a bone stock 180 with 72,000kms so I'm fairly certain that its from the factory and not part of a modification that someone made but I could be wrong.
