Unlike a catch can, it returns the separated oil to the sump above the oil level, so it needs no emptying, and it is heated by engine coolant to stop water condensation reaching the oil.\u003c\/p\u003e\u003cp\u003eThe VTA version vents through a slotted, baffled top and has two side inlets, suiting dual-bank engines with two crankcase vents. A large outlet chamber slows the air so contaminants drop out, and a diffuser returns oil sludge to the can. An integrated water trap around the bottom edge keeps condensation out of the sump, and the billet unit splits into three large pieces for service.\u003c\/p\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Return:\u003c\/strong\u003e Separated oil drains back to the sump - no emptying required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Heated:\u003c\/strong\u003e Heating chamber keeps the unit warm and prevents internal condensation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Trap:\u003c\/strong\u003e Integrated trap keeps condensation out of the sump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Stage VTA:\u003c\/strong\u003e Large outlet chamber and diffuser, designed not to restrict flow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Inlets:\u003c\/strong\u003e Two 7\/8\"-14 (10AN ORB) side inlets for dual-bank engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eServiceable:\u003c\/strong\u003e Splits into three large pieces; dipstick for inspection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e360° Mount:\u003c\/strong\u003e Aluminium mount allows full rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMachined aluminium AOS-R (VTA)\u003c\/li\u003e\n\u003cli\u003eAluminium mount allowing 360° rotation\u003c\/li\u003e\n\u003cli\u003e2 x 5\/16\" barbed coolant fittings\u003c\/li\u003e\n\u003cli\u003eStainless steel hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eOptional Parts\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\nRadium 14-0351 10AN ORB Plug, Round Internal Hex (14-0351) - plugs one inlet for single-vent setups\u003c\/li\u003e\n\u003cli\u003e\nRadium Air Oil Separator - Universal Kit (20-0219) - VTE (vent to engine) version, recommended for MAF engines\u003c\/li\u003e\n\u003cli\u003e\nRadium O-Ring Service Kit (20-0685) - AOS-R O-ring service kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNot recommended for MAF (mass air flow) engines - the vent creates an air leak; use the 20-0219 VTE version instead\u003c\/li\u003e\n\u003cli\u003eFor a single-vent setup, plug one inlet with Radium 14-0351\u003c\/li\u003e\n\u003cli\u003eThe engine needs a breather\/return port high enough to keep oil from being drawn into the unit but low enough for a downhill hose back to the engine; the unit's bottom port must sit higher than the engine return port\u003c\/li\u003e\n\u003cli\u003eCoolant must be routed to the unit for heating; in freezing climates insulate exposed hoses (sleeving not included)\u003c\/li\u003e\n\u003cli\u003eWhen operating properly the unit is empty after sitting - remove the dipstick to inspect if a return obstruction is suspected\u003c\/li\u003e\n\u003cli\u003e10AN ORB fittings and hoses are not included\u003c\/li\u003e\n\u003cli\u003eInstallation instructions are available in the Instructions tab\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eUniversal - see Application\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eFor application support, send your vehicle details to TJ Auto Parts through the Parts Finder.\u003c\/p\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":67911642644734,"sku":"20-0819","price":531.04,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8920\/6526\/files\/20-0819_86210f6a-c1a9-47e4-bb87-b4f94b4e0ce5.jpg?v=1793339437","url":"https:\/\/tjautoparts.com.au\/products\/aos-r-universal-vta","provider":"TJ Auto Parts","version":"1.0","type":"link"}
