This kit creates a high-flow engine vent port using the billet oil fill cap and includes hose and a billet aluminum PCV valve to connect to the intake manifold. This creates a closed loop vent system that pulls fresh air through the engine. This system is superior to the OEM "PCV" vent system in many ways.
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.
