Radium Engineering PCV (positive crankcase ventilation) valves are not simple one-way check valves. Radium's valves have an internal plunger that dynamically meters the appropriate amount of crankcase vent airflow based on current engine load, preventing the "vacuum leak" that a check valve would create at low loads. Also, in the event of a backfire, these PCV valves prevent combustible vapors from igniting in the crankcase. Offered in two outlet sizes, Radium PCV valves feature 6061 aluminum construction with a durable Type-II anodized finish and include sealing O-rings. Specs: * Inlet: 10AN ORB (7/8 in.-14 threads) * Outlets available: -- 3/8 in. Barb (9.5mm) -- 6AN Male

On steep inclines/declines, engine oil flows to the rear/front of the engine and valve covers. At extreme angles, the factory PCV system allows engine vacuum to draw oil through the PCV valve and intake into the combustion chamber. This causes exhaust smoke from the burning oil and possibly hydro-locking the engine, as well as other internal damage.
