The problem of the breather thing is a lot more than that!
PCV ( positive crankcase ventilation valve) could be hidden in the back of one cover and a breather where your puke tank is now.
Most of us forget that as much air is moved on top of the piston , the same is moved at the bottom , ie, in the crankcase. with a vacuum sucking that air out of the crankcase you can minimise the
oil that is puked, removing the need for a puke tank. Leave it there unconnected if you have to have it to look good. not only does the vacuum help the puking it helps seal the rings,by illiminating the crankcase pressure under the rings,h helps to stop blowby. Why try to keep something that has been proven not to work?
