Turbo Oil Line Restricter?

[bluegts]

Hi,

I have just put a standard rb25 turbo on a rb25de. It was going great until this weekend when the turbo started whining a lot louder than usual, nothing has changed in performance, just a noticable increase in noise as it spools up. (not induction sound, turbine sound).

Now, when I put the turbo on I used the standard oil line (or what I thought was as it lined up pretty close). In one of the banjo fittings, on the inner ring, one of them was kind of filled with a 1mm hole in it, and the other end of the line was just open. Have I used the wrong line for oil? Or is that how the standard rb25 oil line is?

Was just thinking maybe I've been starving the bearings with oil... (im running penrite hpr 10 btw)

The turbo came off an auto 98' s2 with 90,xxx's so it should be a healthy turbo, wasn't any play and initially sounded fine, and performance wise it's goin hard and have only been running 6-8psi.

Thanks, Jack
