Usually the only turbos that require a restrictor are the newer ball bearing turbos. The exhaust side of that turbo looks a little dark. It may be possible that the piston seal on the tubine side in the turbocharger is coked and the drain inside the turbo is plugged with carbon which won't allow the oil to drain down so it goes past the piston ring into the turbine housing. First thing would be to remove the scavenge pipe(drain tube)
from the turbo, put a catch pan underneath and have someone start it and run it for a minute and see if the turbo is draining the oil out enough. There will be no pressure so it should just flow out and don't run it too long like that. You would still get some flow from the compressor side bearing draining down but the leaking at the turbine wheel should be nill if the turbine side isn't plugged up. I would then suspect scavenge pump issue. I also noticed a second pipe feed into the drain tube...what is that for??? and where does it go to at the other end?
As for the turbo...centre section should have a tag depicting what tubo it is.
