I have a MHI TC05 turbo but i have a issue with the oil feed and return lines, i know the oil feed line is the thin one, and the oil return line are the bigger, but my oil feed are facing down and my return line is facing upwards.

My question is: Can i switch the oil lines, the big as oil feed line, and the thin as oil return line. Or there is no problem and can use the oil feed and return as it.

 

no, you need to rotate the center section
