s13 sr20 turbo line confusion

[mrchomponthis]

I have a stock s13 sr20det and i am trying to put it back together since i am selling the car. I have an s14 water neck with steel braided coolant lines and stock oil hard lines. I put everything back together and the car runs but after about 15 second it starts blowing white smoke. i am now second guessing my stock t25 turbo but then i thought i may have routed the lines incorrectly. I have searched for info but i haven't found any good pictures and info on this. Can someone please help me out. ASAP thanks

Check to see if your oil return line is pinched or has a kink in it.

I've double and triple checked all the lines. i think I have them all in the right spot. The runs fine for about 15 to 30 seconds then all the sudden is progressively starts smoking then it gets worse and worse. i am thinking the turbo seals are bad? any other ideas people?
