Radium Air Oil Separator - Universal Kit

Radium Air Oil Separator - Universal Kit

Application: Universal – all engine types with a suitable crankcase breather/return port
Part Type: Air oil separator-return (AOS-R), vent to engine (VTE)
Part Number: 20-0219

High-output engines often produce more blow-by oil and gas than a small catch can can handle. The Radium Universal AOS-R separates oil and contaminants from crankcase vapour before they reach the intake, then returns the collected oil to the sump above the oil level – so, unlike a catch can, it needs no emptying.

Engine coolant circulates through a heating chamber to keep the unit warm and prevent internal condensation, while a water trap around the bottom edge stops water reaching the sump. Part 20-0219 is the vent-to-engine (VTE) version with a top inlet and side outlet routed back into the intake or turbo inlet pipe – recommended for MAF-equipped engines.

Key Features

• Oil Return: Returns separated oil to the sump – no emptying required
• Coolant Heated: Heating chamber prevents internal condensation
• Water Trap: Keeps water from reaching the sump
• Vent to Engine: Top inlet and side outlet – suits MAF sensor engines
• Serviceable: Splits into three large billet pieces; dipstick checks for a return obstruction
• Rotating Mount: Aluminium mount rotates 360°
• Cleaner Intake: Reduces oil build-up in the intake, intercooler, throttle body and manifold, and lowers hydrocarbon emissions

What's Included

• 1x Machined aluminium AOS-R unit
• 1x Aluminium 360° rotating mount
• 2x 5/16in barbed coolant fittings
• Stainless steel hardware

Optional Parts

• Radium Engineering AOS-R - Universal VTA (Vent to Atmosphere) (20-0819) – vent-to-atmosphere version (not recommended for MAF engines)

Important Notes

• The engine needs a breather/return port high enough that oil is not drawn from the sump, yet low enough to connect to the AOS-R bottom port
• Mount the AOS-R so its bottom port sits higher than the engine return port, with the return hose running downhill
• Coolant must be routed through the unit to prevent condensation
• Insulation sleeving (not included) is recommended on hoses exposed to cold air
• 10AN ORB fittings are required for the inlet, outlet and return ports (sold separately)
• Installation instructions are available in the Instructions tab
