- 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
- 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.

Verified buyerRunning between three rig sites every week, was burning through DEF in about 2 weeks. Getting 6 weeks per jug now. Regen lockouts used to cost me half a day in the field, that's done with.
Chris D.
Verified buyerGot four trucks on the ranch, did this one first to see how it'd go. Eight months in, no codes, pulls hay like she's new again. Other three are getting done before winter.
Travis M.
Verified buyerTowing the boat down to the Keys used to kill me at 11 mpg. Got 15.4 last trip, same boat, same route. Pipe looks stock from the outside, none of my buddies even noticed it's gone.
Mike R.
Verified buyerHauled my horses from Fort Worth up to Amarillo last month, got 17.8 empty on the way back. Was running around 13 before. Pulls a lot better up the grades too, didn't expect that part.
Jason T.
Verified buyerUsed to go into regen every 280 miles when I was loaded down, now I'm pushing 580 with no regen at all. EGTs run way cooler too pulling the skid steer. Wish I had done this sooner, honestly.
Brandon L.
Verified buyerBought it used and the previous guy had wiped the delete history clean. Got everything put back the right way, ran the protocol, passed smog first try. Truck finally drives like it should.

Got questions?
The stuff that keeps you up at night before you commit. Answered in plain talk by guys who actually wrench on these trucks.
A full mandrel-bent stainless DPF and CAT delete pipe, EGR block-off plates and gaskets, DEF delete components, all mounting hardware and clamps, and your preloaded tuner with the custom tune for your VIN. We don't ship anything you don't need, and we don't leave anything out that you do.
No. The custom tune disables the codes the deleted hardware would otherwise throw. Dash stays clean. If a real fault code pops up after install, call our line and a tech walks you through it. Usually it's a sensor that got unplugged during the wrench work, takes 5 minutes to sort out.
We pull your VIN before we ship. Engine, year, trim, cab config, all verified against the kit. If it doesn't fit your truck, you send it back and we either ship the right kit or refund you in full. Fitment is on us, not you. That's why we call it a fitment guarantee.
Most of our customers do. Average install is 2 to 4 hours with basic hand tools, sockets, ratchet, jack stands. You'll get the step-by-step install video emailed after purchase and a 24/7 phone line if you get stuck. If you can change your own oil, you can run our protocol.
Real custom files. Built in-house by guys who've been turning wrenches and writing tunes on Cummins, Duramax, and Powerstroke platforms for years. Every tune is dialed to your year, your engine, and how you actually drive the truck. No outsourced generic tunes pulled off a shared drive.
Once we've got the base files for your platform, dialing it in for your specific truck takes about 20 minutes. Charging $300 for that didn't sit right with us. We'd rather give you the better experience and earn the call when your buddy's truck needs help.
You call us. Real diesel techs, US-based, picking up the phone. We help with install troubleshooting, tune adjustments, fitment issues, codes, anything. We don't disappear after the sale, and the line doesn't go to voicemail. Phone number is at the bottom of every email and on every page of this site.
Yes. The custom tune is reversible, flash the stock file back through your tuner and the truck reads as factory again. The only thing that's permanent is the deleted hardware itself, but most buyers in the diesel community see a properly executed delete as a value-add, not a deduction. We can also ship the OEM-style reverse plates if you want to put the factory exhaust back on for resale.
Lifetime warranty on the stainless delete pipe, no rust-through, no cracks, ever. 2-year warranty on the EGR delete plates, gaskets, and hardware. If anything fails, we ship a replacement same day. The tuner itself carries the manufacturer warranty through EZ Lynk or HP Tuners.
Orders ship from Fort Worth within 1 to 2 business days. Free express shipping anywhere in the lower 48. Most orders land in 3 to 5 days. You'll get tracking the second it leaves the shop.
