I really don't want to ask this question, but how do you tell which hole on the turbo is for what. From what I have found, want to make sure on the heart of the car, but the oil inlet is on top and outlet on bottom. Then for the water, the inlet is slightly lower than the outlet? Some helpful info would be great. Thanks in advance! Turbo is a Garrett GTX3067R

Googled Turbo Diagram, this one seems relevant, not for a Garrett it appears, but /should/ apply.
