Radium Engineering VTA Baffled Oil Cap for Multiple GM Vehicles - 20-0588
Anodized aluminum billet oil cap for many General Motors vehicles.
There are 2 different oil cap styles used on LS-based engines.
This oil cap has special features that consolidate the differences.
The top 7/8"-14 threaded port accepts 10AN ORB adapter fittings. Furthermore, it features internal stainless steel baffling that can be used for crankcase venting air/oil separation.
20-0539 OIL CAP, GM
Anodized aluminum billet oil cap with a 10AN ORB plug to block-off the internal baffle. This is simply a replacement oil cap. Nothing else is required.
Confirmed Engine Compatibility:
LS1, LS2, LS3, LS4, LS6, LS7, LS9, LSA, L76, L99, L9H, LT1, LT2, LT4
NOTE: there are other compatible engines not listed.
Optionally, the center 10AN ORB plug can be unscrewed and removed. Underneath is a cleanable and reusable stainless steel baffle for air/oil separation.
20-0588 BAFFLED OIL CAP VTA KIT, GM
This is a VTA (vent to atmosphere) anodized aluminum billet oil cap. It is a direct replacement for the OEM oil cap.
Confirmed Engine Compatibility:
LS1, LS2, LS3, LS4, LS6, LS7, LS9, LSA, L76, L99, L9H, LT1, LT2, LT4
NOTE: there are other compatible engines not listed.
This kit prevents the crankcase from pressurizing. The vented oil cap adds additional air/oil separating filtration to the crankcase that is service free. The 10AN adapter fitting features an integrated check valve for roll-over protection.
NOTES:
1. VTA kits are not allowed in some racing organizations and sanctioning bodies.
2. Depending on the vehicle, an ECU code could be trigged since the engine is no longer burning all the metered air.
3. If the engine is degreased, the filter must be covered to prevent foreign liquids from entering the engine.
20-0587 BAFFLED OIL CAP VTE KIT, GM
Crankcase blow-by quickly escalates during aggressive driving. Excess oil saturated air circulating back into the air intake stream can degrade performance. Filtering these crankcase vapors out of the intake will effectively increase the octane of the burned gases.
This system features a VTE (vent to engine) anodized aluminum replacement billet oil cap. It has an integrated air/oil separator that accelerates oil condensation through a reusable stainless steel baffle. Furthermore, a new O-ring sealed PCV valve is introduced that prevents intake pressure from entering the crankcase. Also, in the event of a backfire, the PCV valve prevents combustible vapors from igniting in the crankcase.
Confirmed Engine Compatibility:
LS1, LS2, LS3, LS4, LS6, LS7, LS9, LSA, L76, L99, L9H, LT1, LT2, LT4
NOTE: there are other compatible engines not listed.
WHY DO I NEED THIS?
For Gen IV LS engines (2005+), this kit reintroduces a true PCV system. If the engine is turbocharged or uses a centrifugal supercharger, the crankcase will pressurize without a PCV valve. This can lead to engine sealing issues. This kit adds a billet O-ring sealed PCV valve which restores crankcase vacuum in all scenarios and only allows metered air into the intake. The baffled oil cap also adds additional air/oil separating filtration to the crankcase that is service free.
Although optimized for Gen IV LS engines, this kit still works on Gen III LS engines (97-04). It replaces a potentially old brittle PCV valve with a new billet O-ring sealed PCV valve. It also adds additional air/oil separating filtration to the crankcase that is service free.
