I am a touch confused, didn't the Cam Chest - Oil Tank Vent Kit do this? Surely using the "old" Vent Kit with the alteration previously mentioned to the Engine Breather pipe would resolve the pressure build up without having to go to a new tank? That will be difficult to ascertain now you have fit the new tank.
