Radium Engineering 20-0819 Universal Air-Oil Separator VTA Kit

Vehicle Fitment

• Universal fit -- fits most performance engines with crankcase venting (single or dual bank).

Fitment Notes

• Vent-to-atmosphere (VTA) version -- not intended for closed crankcase recovery systems unless legal in your area.
• Requires an accessible return port to oil pan or suitable mounting above the engine's return height.
• Coolant lines may need routing if used on applications in cold climates to prevent condensation.

Features

• Large volume billet aluminium canister captures oil mist and blow-by vapours before venting to atmosphere.
• Dual inlet ports -- ideal for dual bank V8 or twin-turbo set-ups.
• Oversized outlet ensures minimal restriction and promotes efficient crankcase venting.
• Integrated water-trap design reduces condensation and prevents water ingress into oil pan.
• Optional coolant jacket prevents internal condensation in cold-weather use.
• High-quality machined fittings, mounting bracket, and hardware provided.
• Serviceable design allows periodic internal cleaning and maintenance.
• Finely engineered for motorsport and high-boost applications where effective venting is essential.

Product Description

The Radium Engineering 20-0819 Universal Air-Oil Separator VTA Kit is designed for high-performance engines experiencing significant blow-by or crankcase venting. Ideal for turbocharged or modified naturally aspirated applications, it captures oil and vapour from the crankcase, separates the liquid, and vents the clean air safely to atmosphere. Its dual-inlet, oversized-outlet design ensures efficient flow even in high-boost or high-RPM environments.

This unit is built for versatility and durability: CNC machined billet aluminium construction, optional coolant jacket for cold-weather use, and service-friendly design make it a reliable choice for demanding engine builds. While universal in nature, correct installation--such as above the engine return height, correct hose routing, and mounting away from heat or exhaust--is critical. For engines where vent-to-engine (VTE) routing is mandated by emissions regulations, a different version (not 20-0819) should be selected.
