The 9PHX CCV Delete Kit reroutes crankcase ventilation on 2011-2016 6.6L LML Duramax trucks in Chevrolet Silverado and GMC Sierra 2500HD/3500HD. It replaces the factory CCV path that feeds oil vapor into the intake, which is the main reason LML owners install one: keeping oil mist out of the turbo and intercooler. Fitment is specific to the LML engine years, so it does not carry over to the earlier LMM or later L5P. It suits owners doing their own wrenching who want a simple reroute rather than a full catch can setup.

This is a CCV (crankcase ventilation) and PCV reroute kit for 2011-2016 6.6L Duramax LML diesel engines in Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks. It removes the factory crankcase ventilation system and vents crankcase blow-by instead. This reduces oil deposits in the engine and stops oily residue and sludge from collecting in the intercooler and factory intercooler pipes.
The kit uses a venturi-style design, so it needs no restrictive baffles. It removes the crankcase box on top of the engine, which frees up room under the hood. The routing has no angles, which gives better pressure flow and no oil dripping. It includes a 3/4" x 5 ft reinforced silicone hose designed for oil applications. The components are black anodized.
The kit routes directly to the exhaust. It includes a scavenging system that is welded into the exhaust system, with a 1" barbed -10 fitting. It includes the complete venturi system, so no additional parts are needed for installation.
