FITMENT
- 2011-2016 6.6L Chevy GMC Duramax LML 2500 HD 3500 HD Diesel.
DESCRIPTION
Product Overview
- The factory CCV/PCV system on 2011–2016 6.6L LML Duramax recirculates hot, oil-saturated crankcase vapor back into turbocharger and intake tract.
- Over time, this oily mist coats your turbo compressor wheel, degrades rubber intercooler boots, and combines with EGR soot to form a thick, choking sludge inside your intake.
- The LML CCV PCV ReRoute Delete Kit completely reroutes these oily vapors safely out of the intake tract, venting crankcase pressure cleanly while keeping your entire intake tract pristine
Key Features
- Venturi-Style Design with Zero Oil Loss: The streamlined, no-angle routing offers optimal pressure flow. Combined with a venturi design, it vents unwanted crankcase pressure efficiently without leaving oily puddles under truck.
- Eliminates "Boot Soak" and Boost Leaks: Factory oil mist saturates the rubber intercooler coupler boots. This "boot soak" weakens the rubber and causes hoses to blow off under high boost. This kit stops oil saturation permanently.
- No Intake Gumming or Carbon Sludge: By completely removing oil vapor from the intake system, you prevent carbon sludge from forming inside the intake manifold and grid heater. Your engine breathes nothing but clean, dry air.
- Protects Your Turbocharger: Prevents hot oil vapors from coating and pitting the delicate blades of your turbo compressor wheel, maintaining peak turbocharger health and longevity.
FAQ
Q: Why should I bypass the factory CCV/PCV system? What are the hazards of leaving it stock?
A: The stock system forces hot, oil-saturated crankcase blow-by gases back into intake. Over time, this sticky oil mist bakes under engine heat, forming stubborn carbon deposits that restrict airflow, rob horsepower, and drop fuel efficiency.
Q: Why are a CCV Reroute and an EGR Delete considered the "ultimate combination"?
A: The EGR system introduces dry carbon soot, while the CCV system introduces sticky oil mist. When they mix inside hot intake, they form a thick, cement-like sludge that heavily chokes your intake valves. Deleting both ensures engine breathes only clean, dry air.
Q: What is the benefit of removing the factory crankcase box?
A: The factory box is incredibly bulky and sits right in the center of your engine bay. Removing it opens up the top of your motor, making future maintenance tasks—like servicing injectors, replacing glow plugs, or accessing wiring—significantly easier.
Q: Some bypass kits cause oil to drip under the truck. Will the kit do this?
A: No, Cheap kits use improper hose angles that let oil pool and drip onto driveway. The kit features a streamlined, restriction-free routing that vents vapors cleanly and keeps oil accumulation to an absolute minimum.
