There's no great benefit of upgrading to a closed crank-case breather in my opinion other than reducing the smeech . Is smeech just a Devonshire word?!

If you were to just wang it into the inlet manifold without doing the rest of it, it won't run correctly.

As it is, you just have open air breathing which is fine. As well, you have nothing other than good old petrol and air going into the engine!
