I've done a catch can with a drier from an A/C where the out of the AOS goes into the long side (all the way to the bottom) and then the shallow side goes to the back of the TB. all the oil gets trapped inside the can by 3 layers of steel mesh and the clean air goes back into the TB. this way you still have an enclosed system (not venting to the atmosphere)but you are cleaning what goes into the back of the TB.

I have used it at the track and where my car used to smoke it doesn't anymore all have to do is drain it at the end of the day
