I've run
vent to atmosphere-good, simple and works
Scavenge to exhaust system-too picky, causes check valve issues with too much heat
Catchcan-too much effort and cost
re-route to intake-strongest vacuum, but allows all oil vapor back into the charge pipes just ike a factory car does.
The only 2 I'll ever do again are vent to atmosphere or just hook up pre turbo.
Catchcans are prone to leaks and still allow oil vapor by.
Preturbo style does have benefits, as it creates a nice vacuum and stops the turbo from smoking if your oil drain line is too small.
If your running a 12an drain line (which I do) Just have around 16" of line and use a 1" filter to vent the valve cover to atmosphere, it will drip oil onto the floor but its not a big deal. Its the most cost effective and removes oil vapor from the intake air.
