The Radium baffled VTE oil cap kit for General Motors creates a high-flow engine vent port using a billet oil fill cap and includes hose plus a billet aluminum PCV valve to connect to the intake. The kit enables a closed-loop vent system that draws fresh air through the engine and is described as an upgrade over the OEM PCV arrangement, supplying the parts needed to build the vented oil-fill connection.
