Long winded but I'm attempting to install a BMC CDA air filter/induction kit and was wondering what I have to do with the breather that goes on the side of the air box? I will be removing the aux rad and fitting a flexible duct to route air to the filter. Secondly, I was doing a bit of reading and found that replacing the pcv valve can cure excessive oil consumption. One of my exhaust tips goes black quite quickly. Thirdly, is it possible to vent crank case direct to atmosphere or do I need to use an oil catch can? Thanks guys.
