I know I need a new oil feed. That's one that was made up only so the car can be started and moved, or are you saying this is actually the return that's being used to feed?

Pipe running over throttle body was one of my next queries. its connected to a thing with a copper coil in it. One side goes to inlet manifold, one to dump valve, can't be right though as dump valve doesn't open, just get chatter if you rev and let go.
I've never worked on a turbo car before, so there's a few bits that aren't familiar with me, but it was cheap and apart from needing fettled with seems to run well. So I'll learn as I go, with some advice from some knowledgable sorts from here I hope
