Radium Engineering 20-0587 Baffled Oil Cap VTE Kit General Motors GM

Vehicle Fitment

• Semi-universal fit - compatible with General Motors vehicles using the standard GM twist-in oil fill cap (single-tooth or dual-tooth valve cover fill neck style)
• Common GM applications include: LS-series engines (LS1, LS2, LS3, LS6, LS7, LSA, LS9), LT-series engines, and other GM V8 and V6 engines using the standard GM oil cap fill neck
• Verify your valve cover uses a standard GM twist-in fill neck (single or dual-tooth) before ordering

Fitment Notes

• Works on both single-tooth and dual-tooth GM oil fill neck valve cover styles - no modifications required for either type
• The billet oil cap uses a 7/8 in.-14 threaded port that accepts standard 10AN ORB adapter fittings - allows integration with Radium catch can systems and other AN-based crankcase ventilation setups
• VTE (Valve Train End) designation - this kit addresses the oil fill cap end (valve train end) of the crankcase ventilation circuit, which is the fresh air intake side of the closed-loop PCV system
• For a complete closed-loop crankcase ventilation solution, pair with a Radium catch can kit on the PCV outlet side of the engine
• The included 10AN ORB plug can block off the internal baffle if the port is plumbed directly - remove the plug to expose the cleanable stainless steel baffle for air/oil separation
• Installation instructions available at radiumauto.com

Features

• Creates a high-flow engine vent port at the oil fill cap - significantly better flow than the restrictive OEM breather element, reducing crankcase pressure under high-load and high-RPM operation
• Closed-loop VTE system pulls fresh air through the engine via the oil fill cap and routes it into the intake manifold via a billet aluminum PCV valve - superior to OEM open-breather or restrictive PCV designs
• Integrated cleanable and reusable stainless steel baffle provides air/oil separation at the cap - prevents oil mist from entering the intake without catching it in a separate can
• Billet aluminum PCV valve included - provides controlled, metered airflow into the intake manifold to maintain proper crankcase pressure and prevent oil consumption
• 7/8 in.-14 threaded 10AN ORB port allows connection to Radium catch cans, custom crankcase ventilation plumbing, or can be plugged off with the included AN ORB plug
• Anodized billet aluminum construction for durability, heat resistance, and clean underhood appearance
• Twist-in installation - installs exactly like the OEM oil fill cap with no tools or modifications required

Product Description

The Radium Engineering 20-0587 is a baffled oil cap VTE (Valve Train End) kit for General Motors vehicles with standard single or dual-tooth twist-in oil fill necks. It replaces the factory oil fill cap with a billet aluminum unit featuring a 10AN ORB port and an integrated cleanable stainless steel baffle - creating a high-flow closed-loop crankcase ventilation system that draws fresh air in through the cap and routes it through the engine. A billet aluminum PCV valve and all necessary hose and fittings to connect back to the intake manifold are included. The VTE kit is designed to work alongside Radium catch can systems on the PCV outlet side for a complete closed-loop crankcase venting solution superior to OEM designs.

Semi-universal GM fitment - verify your valve cover uses a standard GM twist-in fill neck (single or dual-tooth) before ordering. For the matching catch can kit for the PCV side, see Radium's GM-specific catch can lineup. Installation instructions at radiumauto.com.
