Radium Engineering Baffled Oil Cap VTE Kit – GM

Crankcase Ventilation Upgrade for Naturally Aspirated & Forced Induction Builds

Excess crankcase blow-by during spirited driving can lead to oil-saturated vapors re-entering the intake, reducing combustion efficiency and overall performance. Radium’s VTE (Vent to Engine) system solves this by combining a billet baffled oil cap with an O-ring sealed PCV valve, restoring proper crankcase function and helping maintain clean intake airflow.

Key Features:

• CNC-machined anodized aluminum VTE oil cap with integrated air/oil separator

• Internal stainless steel baffle to condense and trap oil vapors

• Service-free design – no catch can or draining required

• O-ring sealed billet PCV valve included

• Blocks intake pressure from entering crankcase

• Backfire-safe – prevents ignition of crankcase vapors

• Helps maintain engine sealing under boost by restoring vacuum to the crankcase

Engine Compatibility:

• LS Engines: LS1, LS2, LS3, LS4, LS6, LS7, LS9, LSA, L76, L99, L9H

• LT Engines: LT1, LT2, LT4, LT5

• Additional GM V8s may be compatible

Why It Matters:

• Gen IV LS (2005–2013): Reintroduces a true PCV system for boosted and NA setups

• Gen III LS (1997–2004): Replaces aging plastic PCV parts with billet components

• Improves octane quality of intake charge by removing oil vapor from airflow

• Prevents crankcase pressurization under boost – a common issue in turbo and supercharged builds

An easy-to-install, maintenance-free solution that enhances performance, engine longevity, and crankcase health on LS and LT platforms.
