Radium Engineering PCV valve bypass for GM LT4 and LT5 engines replaces the OEM valve that vents crankcase gases into the supercharger valley. This bypass lets users redirect crankcase airflow externally or connect an oil catch can where the factory design prevents venting, giving clear control over how crankcase vapors are managed without modifying the integrated engine architecture.
