Need some advice on why my car could be blowing oil out the exhuast.

i recently took the turbo apart to find oil coked behind the turbine shaft but not to much inside the center housing. and there wasnt very much wear on the bearing but some. and the thrust washer looked fine also. so i cleaned everything got the ringlands of the so called seals and the rings really good and test drove it and it still smoked, any suggestions?

i am not running a air filter right now while i test.

i have high oil pressure but im running a restrictor

Oil drain looks great to me, id say the seals are definitely shot on the turbo.

Could be caused by a Turbo surge problem which will blow the exhaust side seal.

What kind of answer are you looking for? lol. I mean theres only a few things that cause turbos to smoke.

1.. not running an oil restrictor on a turbo that needs one and shoving oil past the seals. - overhaul turbo and add oil restrictor.
2.. oil starvation and the rings wear out or the shaft gets scarred. usually has shaft play - overhaul turbo and fix oil source issue.
3.. oil doesnt drain well and backs up, blowing out the seals. - overhaul the turbo and fix the oil drain.
4.. wear and tear.. turbo develops shaft play and seals cant contain the oil any more. - overhaul turbo.

notice a trend?

Well since i am running a restrictor my drain is huge im thinking either a. Smaller restrictor or b. Complete turbo rebuild since Just cleaning it didn't work

Try that turbo your boss has laying around and see what happens.

i would but he said if his blows oil then he wants me to buy him a rebuild kit, so i think im going to try a different restrictor and if that doesnt work im just going to buy a rebuild kit and call it a day

I guess that's all you can do.
