ABSTRACT:
A baffle plate for an internal combustion engine is used to separate air and oil as required for recirculation of crankcase gasses. The baffle plate includes oil holes with protrusions extending therefrom. The protrusions extend in a direction opposing the flow of an air/oil mixture. These protrusions prevent oil that strikes the baffle plate from flowing over the hole in the baffle plate and into the air induction system.
