How EGR Works in Your Vehicle & Why It’s Included Did you know that nearly 80% of the air we breathe is nitrogen? But when nitrogen gets hit with those extreme combustion chamber temperatures—over 1370 degrees—it turns into harmful nitrogen oxides. These gases exit your exhaust and enter the atmosphere. The EGR valve helps combat this by allowing some exhaust gases to recirculate back into the intake system. This dilutes the air mixture, causes it to burn slower, and reduces combustion temperatures by almost 150°C, thereby cutting down NOx production and making your exhaust cleaner. 2. Benefits of EGR Delete Kits While the EGR system is great for reducing nitrogen oxides and helping out the environment, the benefits stop there. When it comes to your engine’s performance, the EGR system can actually have negative effects. This is where an EGR delete kit comes into play.

Hey guys! Welcome back to Dynovox tutorial blog. Today, we are going to talk about how to delete EGR on a LLY, LBZ, LMM Duramax. The process of LBZ is very similar for LLY Duramax and LMM Duramax. If you have an LML, that will be a different process. If you find this article useful, please leave your comment below, and if you have questions, ask in the comments or reach out to us on Dyonovox page chat box or any social platform. Anyways, let's get started! EGR deletes, DPF deletes, and similar modifications are for off-road use only, such as race trucks. This isn't for public roads, so keep that in mind before deleting your truck. Also, you'll need to program the truck to shut off the check engine light because you can't just unplug the EGR valve without tuning the truck. I recommend programming your truck and putting on an aftermarket exhaust if you're doing an EGR delete. EGR Delete Process Let’s begin with LBZ. As mentioned, this process is very similar for LLY or LMM Duramax engines. The kit you need for LBZ will comes with a blocker plate, and other necessary components. A Dynovox 6.6L Duramax LBZ EGR Delete Kit is highly recommended here. (Don’t for get to use the code EGR10 for 10% discount and save some money.) Removing the EGR Cooler You can start by removing the EGR cooler. If you're just using blocker plates, follow along until we remove the cooler, then you'll be almost done. Once the EGR cooler is out, You can remove the downpipe and up-pipe, and install new components. First, remove the air intake pipe and disconnect the negatives on both batteries. Next, disconnect the electrical components bolted down with screws and move all the wiring loose. With the wiring out of the way, start unbolting the EGR cooler. Draining Coolant Next move, You can drain some coolant. GM removed the coolant drain on the rod, so we’ll have to pop out the fender and drain the coolant from a line there. After draining, you can get to the EGR cooler. Removing the Downpipe For the downpipe, remove the heat shield on the turbo by taking out three 10-millimeter bolts. The cover is tight, so cut it into two pieces with a zip cut for easier removal. Next, remove the downpipe’s heat shield and then the downpipe itself, sliding it out through the bottom. Exhaust and Up-Pipe Removal Remove the wheel and fender for more room. Loosen the exhaust, then remove the heat shield bolts. Unbolt the up-pipe from the exhaust manifold and the turbo. Use a ratchet to loosen the bolts. If bolts are tight, heat them up to ease removal. Carefully remove the up-pipe, ensuring no bolts snap. Final Steps Compare the old downpipe with the new one—always use aftermarket for better air flow and easier installation. Finally, replace the components, ensuring everything is securely bolted and connected. That's it! If you followed along, your EGR delete should be complete.

Learn about EGR Delete kit for 6.7 Cummins, common issues, and how a EGR Delete kit can prevent failures. 1. Understanding the Importance of EGR Delete 1.1 What is a EGR (Exhaust gas recirculation) Exhaust gas recirculation (EGR) is the move to cut down NOx levels from your engine. It works by mixing some exhaust gases back into the engine's cylinder, swapping out a bit of the air with CO2. This trick lowers the combustion temperature because there's less oxygen in the mix, which means less NOx is formed. You can cool those exhaust gases externally and pipe them into the inlet manifold, or handle it internally through the camshaft. Read on to learn about the role of EGR in 6.7 Cummins. 1.2 The Role of EGR in 6.7 Cummins Engines In the 6.7 Cummins engines, the EGR system is all about cutting down on those nasty nitrogen oxide (NOx) emissions. It does this by taking some of the exhaust gases and sending them back into the intake manifold. This swap cools down the combustion temps because it reduces the oxygen level, which means less NOx gets formed. The exhaust gases usually go through an EGR cooler before heading back into the engine, dropping the intake air temp even more and making the whole process more effective. The EGR system keeps the engine in check, balancing emissions with performance. But, you've gotta keep it clean—over time, the EGR valve and cooler can get clogged with soot and gunk, messing with your engine's performance and fuel efficiency. 2. Common Issues Caused by EGR EGR is basically a slow killer for any engine. That abrasive exhaust is wrecking your rings and internal components. Without EGR, your oil stays way cleaner, the engine runs cooler, you get better MPG, and you spend less time in the shop dealing with busted EGR parts. With EGR, you're looking at an overhaul every million miles. And on new engines, you can’t just delete the EGR or you'll fry the pistons and valves. Manufacturers are cranking up the compression and adding more fuel to run hotter, then using EGR gases to cool things down and control the burn. It’s a tricky balance, but that’s how they manage emissions while keeping the engine from cooking itself. 3. The Financial Impact of EGR 3.1 Repair Costs Associated with EGR Failures Repairing an EGR valve? You're looking at dropping between $376 and $462 on average. Labor's gonna set you back about $90 to $113, and the parts run from $287 to $349. Keep in mind, this doesn’t cover taxes, fees, or any extra repairs that might pop up, and prices can vary depending on where you’re at. 3.2 Long-term Consequences of Neglecting EGR Maintenance If your EGR valve is acting up, you'll definitely feel it in your ride. Expect a rough idle, hesitation, or even stalling when you fire up your engine. Acceleration might be sluggish, and you could notice a serious lack of power, especially when tackling hills. Plus, you'll probably see your fuel consumption go up. 4.
