Looks like a banjo bolt for a water supply line.

It is the oil supply line. I put a 14b in my 99gst and used that oil supply line.

 

[Coldandafraid]

its an "optional" oil supply line.

It's the STOCK Turbo Oil Supply location on a 90.

Ok so its the oil supply line for a turbo. Awesome...it was lose and oil was coming out of it....Now since it is going to the turbo....will it have coolant mixed in?

No, I was wrong. The only thing that should be coming out of that line should be oil. If there is coolant in there, you have other problems.

The oil goes from your head to the turbo. Coolant for the turbo comes from your t-stat housing and goes to your crossover pipe. Each have seperate routes in the turbo. Never should mix.

might have a blown hg or maybe just a leak somewhere else. oil and coolant should not mix.
