The turbo has 2 places for oil lines. 1 is pipe thread and another is slightly larger. Which is the inlet? Also does the inlet need to face upwards?

 

Wow you just came here and started posting without reading a thing didn't you? The threaded hole is for the feed and the larger opening is the drain. and yes the inlet needs to face upward. before you ask how to rotate the turbo because the drain is facing the wrong direction check the stickies. oh and get a rope bitch.
