Try the oil cap test without the loo filter. It's going to be a restriction anyway.

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.
