I don't understand what gets blocked by not having the loo filter. The oil goes into the turbo intake and through the intercooler... That's normal. Restricting it will cause more oil leakage because it makes more pressure in the crank case.

The problem with removing the crankcase filter is with a remapped car creating more crankcase pressure the normal CCV built into the valve cover might not be able to separate the oil vapour from oil so you now have oil getting passed into the cold side of turbo along with the vapours. Flip side though, if you add the filter to stop oil getting passed you can also increase the crankcase pressure and force the oil then through the rings or turbo.
Also, removing the filter puts me back to my original problem of burning oil as its never had a filter until I added one a few months ago
