Protect your investment: The factory PCV system on the LML Duramax routes oily crankcase vapors back into your turbocharger and intercooler, leading to sludge buildup and reduced cooling efficiency. An lml ccv delete or reroute is the ultimate solution to keep your intake system dry and your engine running at peak performance.

FAQ

Q1: Will this PCV reroute kit fit my 2014 Chevy 2500HD with the LML Duramax?
A1: Yes! This lml pcv reroute kit is a direct fit for all 2011–2016 6.6L Duramax diesel engines, including Chevrolet Silverado and GMC Sierra 2500HD/3500HD models. (Note: For 2.8L Duramax owners, we also offer specific kits designed for the 2016-2022 Chevrolet Colorado and GMC Canyon.)

Q2: Is an lml pcv delete necessary for my truck?
A2: While not mandatory, an lml pcv delete is highly recommended. The stock system vents oily mist into the intake; rerouting it prevents carbon buildup, protecting your turbocharger and intercooler from performance-robbing sludge.

Q3: What are the main benefits of an lml ccv delete for engine longevity?
A3: By performing an lml ccv delete, you ensure only clean air enters the combustion chamber. This prevents "gumming up" of intake valves and intercooler boots, resulting in a cleaner engine and improved combustion efficiency.

Q4: Do I need a tuner to install this PCV reroute lml kit on my Duramax?
A4: No tuning is required for the pcv reroute lml itself. However, for full delete setups (DPF/EGR), a compatible tuner like Mini Maxx, EFILive, or EZ Lynk is necessary to prevent "Limp Mode" and clear diagnostic codes.

Q5: Will this help with "Service Exhaust System" or "Limp Mode" issues?
A5: While the PCV kit improves intake health, full delete kits for the 2.8L or 6.6L Duramax are designed to permanently solve DEF fluid quality sensor failures and the dreaded "Speed Limited to 4 MPH" messages.

Q6: Is the installation difficult and what is the typical cost?
A6: Our kits feature a bolt-on installation that usually takes about 1 hour. While a PCV kit is affordable, a full delete setup for a 2.8L or 6.6L Duramax typically ranges from $900–$1,400 depending on the tuner and hardware selected.

Q7: Is this kit legal for street use?
A7: This product is intended for competition off-road use only. Please check your local and federal regulations before installation, as it may not be emissions-compliant for on-road use in certain states.

Q8: Do I need a tuner to install this kit on my Duramax?
A8: No tuning is required for this Duramax PCV reroute. However, if your truck is deleted, pairing it with a tuner like Mini Maxx can help clear potential CEL codes.

Q9: Will this PCV reroute cause oil leakage?
A9: Minimal oil misting is normal. To prevent leaks, make sure all fittings are tight and hoses are properly secured.

Q10: How does this reroute compare to the stock PCV setup on LML Duramax?
A10: The stock system vents oil vapor back into the intake, leading to sludge and gumming. Our LML Duramax PCV reroute kit vents externally, keeping your intake dry and your engine healthier.

Q11: Is this kit emissions-compliant?
A11: This product is intended for off-road use only and may not comply with emissions regulations in certain states.
