What im assuming is insidw the tanks are seperated but cant you just plumb both crank and heads together in line to 1 breather port or is the crank case seperated from the heads inside the breather then venting to atmosphere

sorry to ask but cossie breathers seem alot more involved than a subaru which is crank and heads into a catchtank on 1 port and the oher port vents at the top of the tank to atmosphere and collects oil in the catch tank at the same time
