I have looked at the baily 3 port breather/seperator tank.
The reason i ask about the rocker cover too, is because the ones that only breathes from each side of the block usually use 19mm hoses. But i already have 16 mm pipes on each side of the block and i dont want to change that because i want to avoid the much thicker hoses. So i thought a good alternative to that would be to breathe from the rocker cover too, and then weld an extra pipe in the breather tank.
