Finally got the car back on the road today. After my turbo started leaking oil out of the turbine housing as shown in my avatar photo i sent it back to the company that rebuilt it for the guy I bought the car from. They honored the warranty and replaced the bearings for free and it came back good as new.
Since then, i've spent all kinds of time doing other things.
I replaced the feed line with a -4AN braided line w/ restrictor at the turbo.
Replaced the hard baked drain line as well as the fittings.
Drilled and tapped holes in the intake manifold for 1/8" NPT and put fittings in for the BOV itself and the external Tial WG, so they both have devoted vac lines of appropriate size. I took all the IC setup out and cleaned it, because the previous owner never cleaned out the oil from when the seals went out and he had the turbo rebuilt. As well as replaced a bunch of hardware with stainless because that rusty garbage just won't do.
Results: The Tial BOV blows off clean and sounds great with a super crisp whip. My girlfriend now calls my car the silver dragon because of this noise, don't ask.
Most everything else is great except a small coolant leak that I will track down in the daylight tomorrow.
Now the big problem, my turbine housing is again leaking oil and smoking though not nearly as bad as before. Still of course unacceptable. The bolts on the turbine housing are tight, the oil feed is pumping oil away like a madman, though I do have the restrictor inline (1/8" aluminum poprivet).
All I can do i guess is call Turbo Auto and ask what the heck is going on. I do have an extra SR20 T25 sitting around, but I don't have the adapter so I can put a silicone coupler on it yet. Need to make that pronto. Anyway nice to have the car on the road again after over a month of it sitting in the drive. But the life of a DIY turbo owner is a painful one.
Anyone have any idea outside of my turbo seal being bad on the turbine side?
