Beware with the connection of a "blow- by " hose to the intake side of the induction setup as what can happen can be disasterous !. The idea behind sending a breather hose to the carby top is to use the vaccume effect to draw out the vapours ,however if it really blows by you can just send oily blow by fumes into the induction system. Big smoke! Fouled plugs! Dont do it !
If you vent it to a breather then at least all you do is fill the breather box with oil, not your engine. Remember big motors with big counterweighted cranks dont allow much room in an engine case . Yours could be actual blow by , that is past the rings , in which case a set of total seal rings will help . Or it could be just lack of adequate crank case ventillation. Yours sounds like ring blow by so it would be better to fix the cause. Another thing to look at is if you treated it too nicely during breakin. If you dont get those rings through the rev range properly you can glaze the cylinder walls and the rings will never seal properly. Anyway ,just try a proper breather box and see how you go. Run the oil on lowest mark and you may find the problem much easier to cope with . Let me know. Good luck! :haveadrin
