Default turbo oil return line
how low do your turbo have to be before you ahve to get a scavernger pump. my turbo sits right in front of the harmonic balancer and im draining in the side of my oil pan so yes my turbo is a few inches above the oil pan but i dont know if it have to be way high to use gravity return.

Sounds like it should be fine, is it smoking at all?

As long as your drain line has a downward slope and is not draing below the oil level in the pan while running you will be fine.

Just shoot for a down hill slope and for the drain opening to be above the oil level in the pan. You will be fine.

Good question. So is it also ok to clock the turbo drain a bit (45* or under) or does it need to be straight down?
