What Does the CCV Reroute Kit Do on a Duramax?
Stock CCV systems recirculate oily blow-by gases back into your intake, leading to carbon deposits, reduced efficiency, and costly repairs.
On a reverse-level Duramax, this can clog your turbo and intercooler fast, especially under heavy towing or tuning. The hidden damage? Oil ingestion causes power loss, sensor failures, and skyrocketing maintenance bills.
Our LLY LBZ LMM LML L5P CCV upgrade vents blow-by pressure safely, keeps your intake tract spotless, and deletes the factory CCV box for a streamlined setup.
Benefits include reduced pollution in your intake, turbo protection, improved performance, lower costs, and optimized engine bay space for other mods.
Is a Duramax CCV Reroute Legal?
It depends on your location. In CARB states like California, venting to the atmosphere might not pass emissions—our kits are designed for off-road, racing, or agricultural use only.
Always check local laws before installing an LLY LBZ LMM LML L5P CCV delete or similar.

Frequently Asked Questions
Q: Does a Duramax CCV reroute void my warranty?
A: Installing a Duramax CCV reroute kit may potentially void parts of your factory warranty if it's considered an emissions-related modification, so always check with your dealer or manufacturer beforehand to confirm.
Q: Best catch can vs. CCV reroute for Duramax?
A: A catch can is ideal for capturing and separating oil vapors to keep your intake clean, while a full CCV reroute redirects blow-by gases entirely away from the intake; for optimal protection on a Duramax, combining both provides the best results over using just one.
Q: How often should I empty my catch can?
A: You should check and empty your catch can every 3,000 to 5,000 miles, or more frequently if you're towing heavy loads, driving in hot climates, or noticing faster buildup.
Q: Will rerouting my Duramax CCV improve fuel economy?
A: Yes, rerouting your Duramax CCV can improve fuel economy by maintaining a cleaner intake system, leading to more efficient combustion and reduced power loss from oil contamination.
Q: Is vent-to-atmosphere legal in my state?
A: Vent-to-atmosphere CCV systems are often not legal for street use in states with strict emissions regulations like California (under CARB rules), so verify your local laws—opt for closed-loop systems if compliance is required.

So far so good with my AFM delete on my 2017 Silverado
5.3 with the factory sport exhaust. I haven’t driven far yet but I can already feel the difference at low speeds being my V8 mode is always on now. The light goes off after shutting my truck off so no battery drain. Before my truck had like a flutter sound at low rpm at speeds around 40mph I guess that’s when my V4 mode was kicking in. But instantly that’s gone now also just slightly pressing the gas pedal now the engine comes alive quicker than before. I’m very satisfied so far and for the 40s $ price range. I first looked at one for around 300 bucks. 5 stars I’m impressed thanks

Ordering process with short, sweet, and to the point; exactly how I like it. The product arrived when it was supposed to. I would definitely order from this company again.

Great overall

it was easy to install and great delivery, got it within 4 days of ordering
I just received the fuel management delete module and let me tell you how happy I am with this thing… all it was claimed to be… very fast shipping…AAAA+=++!!

I know now that my Chevy 5.3 will not fail after 90k miles as the stupid 4/8 change system has been eliminated. Super easy plug and play on my Silverado.

Product came i plugged it up and it works the way it states i recommend everyone with a5.3 and 6.2 get this ASAP

EGR Delete Plug Kit for 2010-2024 Cummins ISX 15 CM2250 CM2350 Plug Kit

Nice!

Stops the motor from kicking down to 6 or 4 cylinders which is supposed to add years to the motor. Thanks

Even before I purchased this, I was experiencing minor hesitation issues without the Check Engine Light. Also since I purchased this truck 4 yrs back, as I type this out, I had to replace the EGR within 3 months. Other vehicles owned with EGR have not experienced this level of issue when the code was checked on the CEL. Now I have been living with the EGR issue in recent months this time, until I determined what steps I wanted to take to permanently resolve this. After weeks of searching, and no real difference between everyone I looked at on the web, and it kinda was a no brainer, spend the money on a new EGR valve, or spend the same amount and eliminate, in essence bypass the valve emission system all together, especially since this truck at 35 years is not required emissions check in this state at 25 years.
My apologies for taking this much time to respond. The block off plate in this kit for my truck is not necessary. The plug on the sensor was removed, the slave was set, the wiring harness secured to a location out of the way of any issue, CEL cleared. After 3 days with some minor hesitation issues still existing, it was determined the vacuum line originally left alone might need to be plugged. To conclude since the vacuum line was plugged there were no signs of hesitation from standing start or any driving conditions requiring further increased pressure on the gas.
Thank you I am pleased with the response, the resolution of the EGR issue, full stop...

I bought the kit with the up-pipe to delete the EGR cooler feed inlet from the exhaust instead of the small disk that blocks it off. My mistake but, don’t get pinched like I did.

I run a small business, and it ain't always easy. Sometimes the best you can do is correct mistakes when they happen. I had a problem with the two AFM disablers I purchased (purchased together).
I contacted EGR and they acknowledged they did have an issue with some of them. They immediately sent me two replacements and the replacements are working fine.
In my opinion, that's how it should be. Thanks.
