CCV/PCV Delete Kit for 2004–2010 Duramax 6.6L (LLY / LBZ / LMM)

Say goodbye to oily intake boots and engine bay mess. This complete CCV reroute kit is designed to eliminate crankcase blow-by issues on your 6.6L Duramax, keeping your engine cleaner and running stronger for the long haul.

Why Delete Your CCV/PCV System?

The stock closed crankcase vent (CCV/PCV) system on Duramax engines is notorious for allowing oil vapors to recirculate back into your intake. Over time, this leads to:

  • Gummed-up intercooler boots

  • Oil-soaked turbo inlet pipes

  • Reduced performance and longevity

This CCV delete kit vents crankcase gases to the atmosphere with a clean, high-flow solution that improves engine health and simplifies under-hood routing.

FAQs

Frequently Asked Questions about the Duramax CCV/PCV Delete Kit

What does a PCV reroute do on a Duramax?

Rerouting the PCV system on a Duramax allows crankcase gases to vent externally, preventing them from entering the intake. This helps reduce oil buildup in the intercooler, turbo piping, and intake manifold, improving long-term engine reliability.

What does a CCV reroute kit do?

A CCV reroute kit eliminates the factory closed crankcase ventilation system, which recirculates oil vapors back into the intake. By venting externally, the kit keeps your intake system clean and minimizes turbo wear from oil contamination.

Is a CCV delete bad for my Duramax engine?

No, it's actually beneficial for off-road applications. A CCV delete reduces oil contamination in the intake system, which can prolong turbo and engine component life. However, it is intended for off-road or race use only.

Will this kit fit my 2007 LBZ Duramax?

Yes, this kit is designed to fit all 2004–2010 6.6L Duramax engines, including LLY, LBZ, and LMM models. It fits Silverado and Sierra 2500/3500 HD trucks.

Do I need a catch can with this CCV delete?

No catch can is required. This kit uses a direct venting system with reinforced hose and high-flow fittings to ensure clean evacuation of crankcase pressure without pooling or dripping.
