PCV Valve Bypass Radium Engineering for GM LT4 LT5 Chevrolet Corvette Camaro Cadillac CTS-V CT5-V - USA-RAD-20-0988 - COMPATIBILITY 2019 Chevrolet Corvette ZR1  15-19 Chevrolet Corvette Z06 17-24 Chevrolet Camaro ZL1 16-19 Cadillac CTS-V 22-24 Cadillac CT5-V Blackwing 23-25 Cadillac Escalade-V OVERVIEW The OEM PCV valve is installed directly into the valley of these engines. Unfortunately, it takes internal crankcase gasses and deposits them directly into the lower housing of the supercharger. Because the architecture is integrated into the engine, there is no way to vent the system or connect an external oil catch can into the system. This PCV valve bypass replaces the OEM PCV valve and allows the user to do what they wish with the crankcase air flow. The space is very tight. Fortunately, with modern technology and 3D scanning, we were able to get a 3/8" (6AN) hose out of this area without any obstruction. The port is tapped for 2AN ORB (5/16"-24). Male and female 5/16" SAE quick connections are included. Also, a 2AN ORB plug is included if this port needs to be capped off.
