225 engine spraying oil

The breather(s) are where the air is allowed in to the crankcase, the PCV valve/ hose connected to the manifold is where the gases are evacuated(sucked out). If you have oil entering the air cleaner you either have a blocked PCV system(on the vacuum side) or more crankcase gasses than the system can handle & it's backing up into the air cleaner. Blow-by from worn rings, that kind of thing.
