PCV (Positive Crankcase Ventilation) system recirculates the blow-by gas inside of engine for emission regulation. As the blow-by gas transports oil droplets to air intake system that can result in oil consumption, deterioration of engine durability, engine torque drop and harmful emission, an oil separator with good efficiency is required. In this study, an experimental approach was taken in order to investigate an influence of each design factor of baffle separator to oil pullover through breathing air passage in high load conditions. Transparent cam cover was made to find out the oil pullover to breathing passage. After radical oil reversion phenomenon was observed, pressure distribution in cam cover oil separation chamber was measured in some areas to investigate an influence between pressure drop and oil reversion. As main factor was defined by visualization test and pressure measurement, some alternatives are developed to reduce a pressure drop and oil reversion. The final solution to prevent drastic oil reversion was verified through oil pullover test with catch jar.
