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.

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.
