We recently built a catch can for a friend of ours who was having problems with his breather vent spitting oil. Well, it wasn't baffled! We remade a new tank but added baffling provisions to effectively separate the oil and allow dry air to vent out of the cleanable K&N filter we supply. 2 -10AN inlets as well as an optional -4AN inlet for the transmission. There is also a -4AN drain with cap.
