Four Stroke Valve Train Lubrication
I have a concern with the lack of oil making it to the top end of my four strokes. My little Saito .30 especially. I have done searches and basically found threads that the over all conclusion has been they seem to keep their integrity despite very little oil migration and to manually lube them occasionally if you choose to worry about the fact. I can't begin to claim more knowledge than the engineers at Saito, OS, etc. but has it been tried or even discussed here that it may serve well to maybe add some nipples to the rocker covers so the crankcase vent is routed first low on the rocker cover(s) then from a higher nipple to a vent hose? The idea obviously being that the rockers, valve guides, etc benefit from the oil expelled from the factory vent before it is ejected? I would think there is enough blow by to prevent the crank case from puddling?
