2011–2016 Chevy GMC 6.6L Duramax LML CCV/PCV Reroute Delete Kit

2011–2016 GM 6.6L Duramax (LML) CCV/PCV Reroute Delete Kit

Clean up the top of your LML and stop crankcase vapor from coating your intake tract. This kit replaces the bulky factory crankcase “box” routing and reroutes blow-by vapors so they don’t get pulled back through the turbo inlet, helping reduce boot soak and oily buildup in the intercooler/intake piping over time.

Highlights

• Vents crankcase blow-by to help reduce oil deposits and intake gumming.
• Eliminates the factory crankcase box on top of the engine for a cleaner engine bay and more room under the hood.
• Venturi-style design intended to avoid restrictive baffles and promote smoother ventilation flow.
• Oil-ready hose: includes 5 ft of 3/4" silicone-reinforced hose designed for oil applications.
• Black anodized aluminum components for durability and corrosion resistance.

What’s included

• 5 ft 3/4" hose
• Vent/adapter hardware + seals
• Hose clamp(s) + routing ties
• Additional fittings/baffles shown for the venturi assembly
