TURBO OIL LEAK??
 

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.. ;D

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

Re: TURBO OIL LEAK??
 

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?

Re: TURBO OIL LEAK??
 

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.
;D great site....
