Designed specifically for 2011–2016 Chevy/GMC 2500HD and 3500HD trucks with the 6.6L LML Duramax, this CCV/PCV Reroute Delete Kit is the go-to solution for eliminating the factory crankcase vent box and all the problems that come with it.
The stock system vents oily crankcase vapors back into your intake, causing gummed-up turbo components, boot soak, and reduced engine life. Our upgraded aluminum venturi-style system reroutes crankcase blow-by away from your intake, drastically reducing oil deposits and helping your engine breathe cleaner, run cooler, and last longer.

• Direct fit for 2011–2016 6.6L LML Duramax (2500HD/3500HD)
• Vents crankcase blow-by externally, reducing intake gunk and turbo contamination
• Eliminates the factory crankcase box—frees up valuable engine bay space
• Venturi-style design improves flow with no restrictive baffles
