turbo question

[Jeronkie]

Ok Guys

Please help 

I got a new GT3076 and I see on the oil feed side inside there’s a  thing that looks like a small o-ring and in the middle I see a small thread must this stay in there or must I take it out and how do you take it out ,,,I got the restrictor but this is something already inside

Have a picture?

it already has a restrictor inside (what you're seeing.)
