-For the AOS-R to function properly, a return port on the engine must be available on the engine to the oil pan.
-The AOS-R must be mounted high enough in the engine bay so that the port on the bottom is higher than the engine return port.
-For heating purposes, engine coolant must be routed to the AOS-R to prevent condensation.

-Because of the vented "air leak" in the system, the VTA AOS-R is not recommended for mass-air flow (MAF) sensor engines.

Without a properly designed air oil separator, water condensation can develop and find its way in the oil pan contaminating engine oil.

Engine coolant lines are routed through the Radium Engineering AOS-R via the 2 barbed fittings. The coolant enters a specially designed heating chamber (shown below).


20-0219 AOS-R, Universal, VTE
The vent-to-engine air-oil separator has a top (inlet) and side (outlet) port. The outlet port should be routed back into the intake or turbo inlet pipe. The VTE system is a must for mass-air flow (MAF) sensor engines. Furthermore, the VTE AOS-R will not expel an undesireable gas scent into the cabin. Lastly, the VTE system will prevent any potential oil debris from coating the engine bay.


20-0819 AOS-R, Universal, VTA
The vent-to-atmosphere air-oil separator has 2 side (inlet) ports. This is great for dual bank engines that have 2 crankcase vent ports. NOTE: For single crankcase vented engines, simply plug one of the inlet ports with Radium Engineering 14-0351. The VTA AOS-R features one giant non-restrictive outlet that is over 183% larger than the inner diameter of the 10AN inlets. This increase in volume slows air flow allowing contaminants to fall out of suspension. Additionally, contaminants are trapped with a diffuser permitting the oil sludge to fall back into the catch can preventing overspray in the engine bay. Furthermore, it is a dual stage design (located in the inlet and outlet). These free flowing chambers do not create any flow restriction.
