I'm sorry, I'm sot sure I understand.
I need a 180° ben from the turbo backwards, a long piece then a 30° or so bend into the airbox.
The oil breather connects into this pipe.
I could make this part, but I am struggling to find a bend of a tight enough radius to curve around and back to the turbo.
VW did it with a 90° rubber elbow and the air pipe was "J" shaped.
I only have facilities to weld steel. I can get aluminium welding done locally, but again, i cannot find off the shelf aluminium bends in 57mm to contemplate this either.
I don't want to but I fear I may end up making this parts from either silicone hose or flexible conduit

I may just use this to get the vehicle roadworthy and come back to it, it is simple to get to, it's not like I have to strip the vehicle to get to it!
