You need to vent it somewhere, normally those go back to the carbs intake side.

I'm running small filters on the tappet cover and another one on the block outlet.
From experience pressure builds up and want to push oil out.

hi Guys,

just a quick one..i wonder what will happen to the engine if the outlet hose from the rocker cover breather is attach to outlet block breather?

i'm not planning to do so..just curios about it..

thanks.
