Is there an orientation pin present in your turbine housing? That will line up the CHRA so it's orientated correctly for oil Flow. As for the compressor housing, I'm pretty sure there's a pin there as well to clock it correctly.
As GB said, it's a stock replacement. That being said, I've seen some shotty j-pipes in my time that aren't manufactured correctly, therefore giving the illusion that your turbo isn't clocked correctly.
