FITMENT

• Does not fit 3500/4500/5500 Cab & Chassis.

DESCRIPTION

Product Overview

• The factory L5P Duramax CCV system is a major headache for truck owners. To meet emissions rules, the OEM system dumps hot, oil-saturated blow-by gases directly back into turbo inlet.
  
• Over time, this coats your turbo blades, pools oily sludge in your intercooler, degrades silicone boot connections, and cakes intake valves in carbon—robbing truck of power and reliability.
• The L5P CCV Reroute Delete Kit permanently bypasses this flawed design. By venting crankcase gases safely away from intake, this kit ensures turbocharger and intercooler breathe clean, oxygen-rich fresh air.

• Billet Aluminum Durability: Replaces fragile factory plastic CCV fittings with heavy-duty CNC-machined 6061-T6 aluminum to withstand extreme engine bay heat.
• Keeps Intake Clean: Stops hot oil vapor and sticky soot from entering the intake tract, keeping intercooler, turbo compressor wheel, and intake valves completely deposit-free.
• Eliminates Blown Intercooler Boots: Over time, oil mist from the factory CCV saturates silicone intercooler boots, causing them to slip and blow off under high boost.
• Optimizes Combustion Efficiency: By feeding your engine only clean, cold, oxygen-dense air, your air-fuel ratio remains optimal, promoting smoother idle and quicker throttle response.

FAQ

Q: Why is the factory CCV system considered a failure point?

A: It uses fragile plastic and ruins intercooler boots.The OEM plastic components brittle and crack under engine heat, causing boost leaks. Additionally, the recirculated oil mist coats intercooler boots, causing them to slip and blow off under heavy towing loads.

Q: Is this CCV Reroute Kit compatible with a factory EGR system?

A: Yes,It is fully compatible with both stock and deleted trucks. If factory EGR is still active, this kit is highly recommended; it prevents oily CCV mist from mixing with dry EGR soot, which creates a concrete-like sludge that clogs intake manifold.

Q: Is a small amount of oil from the vent hose normal?

A: Yes, Because this kit vents crankcase pressure to the atmosphere, a small amount of oil mist or dripping from the hose is standard. This proves the system is successfully keeping oil out of turbo, intercooler, and intake.

Q: Will this kit trigger a Check Engine Light?

A: No. When installed correctly, this kit does not modify any electronic sensors or engine management components and is designed to operate without triggering a Check Engine Light.
