Can't quit smoking
 
1 Attachment(s)
So the turbo is still smoking. The car is running great thanks to auto-tune but I cannot figure out my smoke issues.

I replaced the oil drain, oil drain flange, oil feed, oil feed fitting, and still the center section of the turbo just looks wet. You can smell it and you can see the smoke if you stare at it. I replaced the oil drain flange gasket because I thought that was trickling oil out onto the center section and causing it to smoke, and it seems better, but it's still smoking.

I know the only reasons for smoke could be too much oil pressure (which I thought was unlikely with the Greddy turbo), a backed up oil return (I've replaced it three times, it is fat and wide open), or bad turbo seals. It almost looks as though oil is just seaping out of the seals and "burning" off on the center section. No oil in the exhaust, no oil in my IC pipes, no smoke coming out of the exhaust, just under the hood.

Here is a video where you can see how the center section just looks wet. Next I'm going to try putting a really small turbo feed fitting on top of the turbo to cut down on the pressure, but I'm just concerned about starving the turbo for oil...

did you use cooper crush washers on the oil feed?

Yep. I have literally put my face within inches of the oil feed and stared at it. I swear it's not leaking. I'm using the original oil feed banjo bolt to hold the new fitting that came with the eBay oil feed kit. The banjo bolt that came with the kit has a ridiculously small oil hole that I was hesitant to use.

I guess I'll try new crush washers before switching the banjo bolt.
