TD05-16g Leaking Some oil on WOT
Ive been dealing with a little oil burning issue for the last month or so that ive had my car back running, where I believe the oil pressure is to high going into my Mitsu TD05-16g.
When I purchased the vehicle, it was running the greddy oil feed line from the Pass side of the engine. I didnt like the oil feed running all the way across the engine bay, so I had an an-4 line made to come from the oil feed on the drivers side of the block on my 1.6. Since then ive been seeing puffs of blue when I get on WOT, as well as oil along the walls of the compressor inlet on the turbo and in the charge pipes.
I searched for running a restrictor on this turbo, and the information is all over the place, but its all mitsu guys running it. Some say it has to have one, some say it will burn up with one. Nothing definitive at all. It just seems like my oil pressure is to high for the Journal bearings, and forcing its way past the seals and then into my exhaust and intake.
Oil pressures about 25~30 at idle, 60+ on accel. Running Rotella T which accounts for some of the oil pressure. I rebuilt the turbo with new bearings/seals less then 1000 miles ago. Drain line for the turbo is a AN-12 hose running into the pan with a very steep slope.
To sum up a long story
60+ PSI oil pressure on Accel
Puffs of smoke
Oil in the Intake of the turbo as well as charge pipes and intercooler
AN12 Drain Line
AN4 Feed line from side of block
Currently no PCV valve hooked up for troubleshooting oil consumption(Catch can on valve cover and cap at intake mani)
Should I run a restrictor and If so what size?
Thanks/

I use a banjo bolt like the one in the link http://www.ebay.co.uk/itm/Turbo-Oil-...item3375e087c9
The hole is around 1.5 mm (60 thou)

The hotside is stamped mitsu, but the compressor side I think has been swapped out. Id guess. That the center section is still mitsubishi tho.
What are your oil pressures like on WOT? I notice that if I just drive around town for a while without getting on it, then I don't have the issue. Only when I really stomp on it do I see the traces of oil in the turbo inlet.

The picture shows the oil port. At the bottom of the port there are 2 ports opposite each other which are around 3.5 mm in diameter through which oil is fed to the bearings. (You only see one of the ports in the picture, the dimple on the bottom is a machining mark.)
If I do not use a restrictor I get oil leaks.
Maybe Subaru TD05s are different to greddy td05s?
