HEY GUYS !! sup? i got a question , i got a missle sishi tdo5-12a turbo charger

ive had it a few years and rebuilt it once it started leaking between the center section and exhaust housing and out the compresser n2 the charge pipe. so i rebuilt the dmna thing again, i,ve rebuilt dozens of mistubishi turbos so i know i did it right the only thing i did different this time was use a smaller oil return two -6 an fittings and -6 ss line . compared to the 3/8 or 1/2 " (inner diam.) hose ive used before . could the oil return flow be too much for the -6 an line and fittings? and be pooling up in the housing causing the oil to come out the exhust seal and compressor seal?

or am in a state of denial from a bad turbo, its been moved around a bit from a conquest , to eg civ, now a 99 clipse how can a fellowgear head get
turbo spec's of the internals so i measure the seals and bearings to see if its beyond repair? i really don't want to replace it ...its very sentimental to me it powered my first 93 civ cupe to decent 13 sec time .. and i'm not done with..

Switch to a -10 drain, and if that doesn't work choke the bitch with a restrictor.

after i make a bigger oil return, how far should i restrict the oil press to at idle 5psi? 10 psi? because its gonna raise with rpm isn't it?

i'm gonna put a press gauge on it til i get the right base press reading but .. how much press should i run in the oil feed line?

Garrett says 30PSI should be the max oil pressure running through the turbo.

Listen thanks a lot , i installed a 1/2" return line and this s.o.b.

and kept installing orfice's in the feed line till it got maxed out at @42psi

burned off old oil and road tested clipse , came back put it up in the air and checked for leaks . none found , thanks for the help guys.
