CCV/PCV Delete Kit for 2004–2010 Duramax 6.6L (LLY / LBZ / LMM)
Say goodbye to oily intake boots and engine bay mess. This complete CCV reroute kit is designed to eliminate crankcase blow-by issues on your 6.6L Duramax, keeping your engine cleaner and running stronger for the long haul.
Why Delete Your CCV/PCV System?
The stock closed crankcase vent (CCV/PCV) system on Duramax engines is notorious for allowing oil vapors to recirculate back into your intake. Over time, this leads to:
-
Gummed-up intercooler boots
-
Oil-soaked turbo inlet pipes
-
Reduced performance and longevity
This CCV delete kit vents crankcase gases to the atmosphere with a clean, high-flow solution that improves engine health and simplifies under-hood routing.

Frequently Asked Questions about the Duramax CCV/PCV Delete Kit
What does a PCV reroute do on a Duramax?
Rerouting the PCV system on a Duramax allows crankcase gases to vent externally, preventing them from entering the intake. This helps reduce oil buildup in the intercooler, turbo piping, and intake manifold, improving long-term engine reliability.
What does a CCV reroute kit do?
A CCV reroute kit eliminates the factory closed crankcase ventilation system, which recirculates oil vapors back into the intake. By venting externally, the kit keeps your intake system clean and minimizes turbo wear from oil contamination.
Is a CCV delete bad for my Duramax engine?
No, it's actually beneficial for off-road applications. A CCV delete reduces oil contamination in the intake system, which can prolong turbo and engine component life. However, it is intended for off-road or race use only.
Will this kit fit my 2007 LBZ Duramax?
Yes, this kit is designed to fit all 2004–2010 6.6L Duramax engines, including LLY, LBZ, and LMM models. It fits Silverado and Sierra 2500/3500 HD trucks.
Do I need a catch can with this CCV delete?
No catch can is required. This kit uses a direct venting system with reinforced hose and high-flow fittings to ensure clean evacuation of crankcase pressure without pooling or dripping.
Let customers speak for us
Honestly, the exhaust was much nicer than I expected fitment wise. It fit just as well if not better than exhaust systems I have installed in the past that were a few hundred more dollars. Shipping time was pretty good as well… received it the same week I ordered it. That’s about all I can speak on for now as I have only put about 100 miles on it.
Everything you need and nothing you don't. The parts install really impressively smoothly.
Could definitely use better / ANY instructions, especially since youtube vids on deleting trucks have been taken down lately.
It took a day of searching and watching vids here and there to find out it is extremely important to go in a certain order:
1: install the tuner first
2: install a "smog equipment has been removed" tune even though the truck still has the equipment at the moment.
3: remove the dpf and egr bits
Money well spent. Install was simple. Do not misunderstand simple with easy. Although it was easy for me. Install of the MINI MAXX V2 was a bit different. The video provided on the site was not how my installation went. In fact it was very different. With that, it did go as expected. The tuner does have some what of a learning curve, not very much info out there now with all the bureaucratic garbage we, in the US, have to contend with. It is out there, just TOUGH to glein. The removal of that gargantuan nightmare of an exhaust filter was not for the faint of heart. It is heavy, and the connectors on all those sensors can be challenging. It will be worth the struggle. The removal of the Extra Grace Required part was the hardest part for me. Having had my exhaust and turbo out 2 times, one of the bolt heads got damaged in the last re-install. That took a huge amount of patience and correctly applied downward force and a special tool. FYI THE PYROS DO NOT READ CORRECTLY ON 2011 F350 IT WILL ONLY READ 1193°!
Then the block off bypass parts, easy install. Looks great and does everything I expected. As a plumber I was able to use some expansion couplings and cut the water tubes and did not use the supplied hose. Then back on the ground to install the exhaust pipe. That was a challenge. The hanger bracket wasn't quite on par and was bent a bit. Nothing like a torch and a quality set of Pittsburgh 3/4" box end wrenches. Got that squared away, lined everything out and the slip joint went in nicely. I only used one of the 3 bolt flange bolts because I saved 2 of the pressed in studs. The down pipe connector flange was a special kind of hurrah. Perseverance, busted knuckle, and lots of upward pressure, accomplished that.! Overall I like the kit, don't like it doesn't come with instructions, but if you're buying this kit I'm betting you're already a mechanic anyway. HUGE THANKS TO SPETUNER.
One more thing, FedEx delivered my 1st kit to 2 wrong addresses, SPETUNER made it right and sent out a new kit for my. That is worthy of my review!

EGR/DPF/DEF Delete 2011-2016 LML 6.6L Duramax All-in-One Kit
Great product and customer service.
i love it
Missing any sort of directions but relatively straightforward nonetheless. In my experience, the SPE logo faces correctly forward when mounted, seems like other folks have complained about that.
Fit perfect, programing was even better easier.
Clean oil!!!
Worry-Free Purchase
Awesome product. Very happy with ease of use and quality. Only bad thing was I got no stickers to add to my box. Even still 5 stars all the way.
Exhaust pipe fit great! Everything from the bends of the pipe to the hanger location as well as the clamps, would definitely recommend to anyone looking for an upgrade for their 2.8 Duramax.
