Radium: PCV Valve Bypass, GM LT4 LT5
OVERVIEW
The OEM PCV valve (shown below) 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.
As shown below, 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.
