An engine assembly includes an engine structure, an intake air assembly and a crankcase ventilation line assembly. The engine structure defines a cylinder bore, an intake port in communication with the cylinder bore, and a crankcase. The air intake assembly is in communication with the intake port. The crankcase ventilation line assembly includes a fresh air line and an oil surge protection device. The fresh air line is in communication with the crankcase and the air intake assembly and provides fresh air to the crankcase. The oil surge protection device is in communication with the fresh air line and defines an oil obstruction inhibiting oil flow to the air intake assembly while allowing air flow between the crankcase and the air intake assembly.
