Radium Engineering Oil Cap - GM (LS / LT Engines)
The Radium Engineering Oil Cap (SKU 20-0539) is an anodised billet aluminium direct replacement for the OEM oil cap on GM LS and LT engines. It ships with a 10AN ORB plug fitted, so out of the box it simply works as a sealed oil cap with nothing else required.
Remove the centre plug and the cap reveals a cleanable, reusable stainless steel baffle for air/oil separation. The top 7/8in-14 (10AN ORB) port then accepts 10AN ORB adapter fittings, letting you build a custom crankcase venting setup with catch cans, roll-over valves or other breather components later on.
Note: Confirm your engine is on the compatibility list before ordering. Installation by a professional is recommended.
