While Duramax injectors are known for their great quality, they are not problem-free. The biggest issue with Duramax LB7 engines is the propensity of their fuel injectors to fail, typically before an engine reaches 100,000 miles. When an injector fails, it can dump an enormous amount of excess fuel into the engine, often at very low speeds. When this happens, the extra fuel is not burned. Instead, it seeps into the oiling system and thus starts filling the engine with diesel fuel.
The bad news is that Duramax injectors are both expensive and difficult to reach in the engine compartment for replacement, which prompted GM to extend its injector warranty to 200,000 miles. The Duramax LB7 enginer is otherwise very reliable. As such, so many people will go through the hassle of replacing some or all of the injectors in their Duramax oil-burners with the idea that they will be keeping their trucks for another 100,000 or 200,000 miles. Diagnosing bad Duramax injectors on a 6.6L Duramax LB7 engine is a very easy thing to do. For instance, if you see white smoke coming from the tailpipe under load when the engine is revved up, it can indicate coolant bleeding past a blown head gasket. On a Duramax LB7, it usually means excess unburned fuel. A good way to test the fuel injectors is to check balance rates, which most diesel shops can do using a scan tool. Balance numbers of -5.8 and -6.5 means that the ECU is frantically trying to get fuel to lean cylinders to compensate for the bad injectors. A balance rate of -4 is considered the maximum allowable, while "good" is usually ± 2. For more information on how to diagnose bad Duramax injectors, visit our website at https://puredieselpower.com/

Do you have a diesel vehicle? If you do, you need to know the right steps to take in order to improve diesel performance. Today’s diesel engines are designed to offer improved fuel economy and lower emissions, making them an excellent choice for car and light truck buyers. The following are some of the ways you can improve the performance of the engine and get more power out of it.
One of the great ways to improve the performance of your diesel engine is installing a turbocharger. When it comes to diesel performance upgrades, a turbocharger is without doubt a good investment that can give you more engine power. The turbocharger can be especially useful if you use your diesel truck for towing and hauling heavy loads. It will basically force more air into your diesel engine’s combustion chamber, giving it more oxygen, which will in turn give it more power. Another thing you should do in order to improve diesel performance is schedule regular diesel engine tune ups. Checking your diesel engine regularly will help detect any problems that could be preventing your engine’s performance and could prevent costly repairs in the future. Since the components of your diesel engine run at very high pressures, it can put a lot of wear and tear on your engine. If periodic maintenance work is performed by an experienced diesel technician, it can improve performance and efficiency and keep your engine running much longer. When choosing a technician to check your diesel engine, it would be good to go for someone who can give you the best advice, service, and diesel performance mods available. Make sure that you deal with people who are specifically trained to work on your diesel engine.

You need to know which parts are right for your vehicle and where to buy them from. There are so many sites online where diesel parts are sold these days. You need to do a comparison check and buy the parts from a trusted source.
Before you go ahead to buy any diesel parts, you need to verify if they are original. The parts you choose to buy should have the manufacturer’s label on them. You should also remember to inquire about the shipping fees and the restocking fees if applicable. If you are buying from a reputable shop, you should not have to worry about anything regarding the purchase of these performance parts. Your biggest priority here is your satisfaction. It is also good to know the name of the diesel part you want to buy. Before you head out to the shops, it is essential to know which type of diesel part you are looking for because not all diesel engines are made the same way, and therefore need different types of diesel parts replaced. For instance, if you start doing your work a diesel engine without any prior knowledge about what diesel part is necessary, you may end up buying the wrong item entirely or an item that does not fit with the current system of your vehicle’s diesel engine. To be on the safe side, you need to find out precisely what diesel engine your diesel vehicle has, what diesel model it is, as well as the year in which it was made.

If you do, you need to make sure that they are properly maintained. A well-maintained fuel injection system will limit the amount of gas needed to power the car, giving you better mileage for every tank of gas. They also make less noise compared to the old carburetor-powered engines and lead to less engine maintenance as your car parts last longer in this type of system.
Having a Duramax lift pump is something that comes with a lot of benefits. The lift pump draws fuel from your gas tank, from your fuel tank and then pushes it to your injection pump. All Duramaxes (from 2001 through 2016), don’t have any kind of a fuel pump. They only have injection pumps. So, when you add a lift pump, it can greatly help performance of your truck.
Adding a lift pump on your Duramax will save your CP3 or in cases with the LML. If you are still stuck with a CP4, it can help save that CP4 from cavitation and ruining a $10,000 fuel system. It is important to remember that these fuel systems are not cheap in these trucks. Putting, swapping in a CP3, or putting in a CP3 alone is going to cost you well over a thousand dollars, depending on the CP3 that you will get. If you get a remanned, it might be a little less than a thousand dollars. However, if you get a brand new CP3 from Bosch or from another company such as Xergy, be ready to spend towards a thousand plus. A lift pump will help save your CP3 pumps and your CP4 pumps from basically going to shit. If you decide to operate the stock form without a lift pump, your CP3, CP4 injection pump will basically pull the fuel through a vacuum, and then has to pressurize the system at the same time. By adding a lift pump, it will save your injection pump so that it does not have to sit there and pull the fuel through a vacuum from the tank to itself, and then pressurize the system at the same time. Instead, it will just pressurize the fuel going into your fuel rails, which then lead to your injectors.

If you don’t, you need to start maintaining and monitoring your engine on a regular basis if you want it to serve you for many years.
There are various problems you should watch out for on your Dodge Cummins engine. One of them is turbocharger failure. This is a more common problem on earlier model Cummins engines, but it can still happen at any point even on the newer models because turbos naturally endure a lot of stress. There are various symptoms of turbocharger problems to watch out for, including leaking oil seals, worn bearings, slow spool, compressor or turbine wheel damage as well as whining sounds. Most of these symptoms come with the age of your turbocharger. Things such as leaking oil seals and worn down bearings can cause many problems in you do not check your engine. You are likely to start experiencing these issues after reaching 120,000 miles in your truck. You should look out for smoke and oil loss because there are clear indicators of turbo problems. It is important to take care of your turbo and be mindful of its wear and tear. While rebuilding a turbocharger in a Dodge Cummins engine is possible, a replacement is usually the better option. Another common problem to watch out for in your Cummins engine is fuel dilution. Even though some fuel dilution is normal for the Cummins engine, but if the levels go past around 5 percent, problems can arise. There are rarely any immediately noticeable symptoms for fuel dilution in the Dodge Cummins engine. For this reason, it is a good idea to do an oil analysis regularly in order to determine dilution levels. After that, you should come up with an oil change schedule as a preventative measure.
