The substance coming from the leak
Not sure what the hose is to or anything (first volvo, first turbo car) i have a series of pictures i just need to know what the name.of the hose is so i can replace it. New to the forum and love the car just need a bit of guidance when it comes to parts etc

Heres the hose that leaks its a metal.line and as you can see where the clamp connects theres a oily substance coming out

This is where the leak and line is located any help would be greatly appreciated ive talked to a few of my friends that work with turbos they say its the oil line to one of my turbos
