why must the turbo oil feed/return be 12/6 o clock?.....

when these guys haven't got it set up straight up/down?

in order to get my turbo to sit perfectly vertical on my manifold i have to redo my oil drain AGAIN!!! and i spent some pretty good $$ getting all the flanges and fittings for the drain

mine sits fairly similar to the first two pics below

helps drain the oil..

well... that part i know but i was told that if i had mine like that i would kill my turbo, just wondering why they can get away with it?

Itll work, but oil might not drain from the turbo causing it to burn up in the turbo which can lead to other problems..

well this is how it sits atm
when i move the hose further in, the fitting sits on the t4 flange and the hose ends up being a bit more horizontal than on a downish angle but will the following work?

They should be straight up and down just to insure the oil is draining out instead of flooding the "seal" and having it leak out if there isn't enough shaft speed.

physics my dear...physics. You need as straight un-ubstructed path for the return, so that it does not create any backpressure. Also why the return lines are so much bigger than the inlets.

The drain must be no more than 10 deg off center. The turbo oil drains off of gravity, with the PCV vacuum helping it along.

Any thing more than 10 deg, and the seals will leak causing smoking and turbo failure on down the road.
