Alright I took my turbo out yesterday, just to replace some gaskets and to stop a leak I had on top of the turbo in the feed line (get rid of the shitty banjo bolt thing in there and replace it with a proper flange), and to add a real gasket to the return and replace my -4AN SS feed line (since I set the old one on fire, don't ask).
All that went well enough, but now, the oil is leaking a prodigous amount of oil out the feed. Like, three times as much as before. It is coming up where the -4AN->1/4" NPT elbow is (I had teflon paste on all those threads), up through the two bolts holding the flange on, and out the sides of the gasket, it is leaking oil into the turbine section so it is burning a bunch as well, and oil is coming out the bottom where the NPT->-10AN fitting is too. What the fuck happened?
I drove around with that old slow leak on the feed for about two months and never had a problem like this. Is it possible that when my old feedline got torched, something got into the turbo? Visually the line was only bad in the middle, it was totally fine towards the turbo side, and I disconnected it right away and never actually put any oil through it to the turbo. The old line still had clean oil in it too. The return line isn't kinked or anything, it worked fine for about two months, I'm going to double check it tomorrow but I don't think that would be my problem. If there is a blockage somewhere in the turbo, how do I clear it out?
edit: other things that might be important, when it was reinstalled, the turbo had no turbine shaft play, only slight compressor shaft play, and trace amounts of oil on the inside of the compressor housing and charge pipes
edit2: well since the oil inlet whole is threaded I could always ditch the flange and put the other elbow I got straight into it, but that doesn't look as good, plus the fuckin flange shouldn't leak anyway. What the hell happened?
