Use a big return line like at least 1/2" ID, plumb it so the line is as short and as vertical as possible, and don't ever let the crankcase become pressurized (easier said than done lol).

Post some pics of what you're working with and your current setup.

5/8" or -10 is the standard for oil drains. Make sure it has a nice sloping run from the turbo to the engine.
