Top Three Reasons For Diesel Engine Failure

Reasons diesel engines fail

Diesel engines are known for their durability and reliability, but they can still fail due to various reasons. Here are three common reasons why diesel engines fail.

Lack of Maintenance

First thing, first. Improper break-in procedures is a problem we see a lot. Many operators receive a new engine and fail to break the engine in properly. Each engine will come with its own set of instructions for this out of our shop so follow them closely to reduce the chance of an early failure.

Diesel engines require regular maintenance to perform optimally and avoid failures. Neglecting maintenance tasks, such as changing the oil, replacing filters, inspecting belts, and adjusting valve clearances, can lead to various problems. Over time, wear and tear on engine components can accumulate, causing reduced efficiency and eventual failure. Proper maintenance schedules and adherence to manufacturer-recommended service intervals are crucial for diesel engine longevity.

Operator Error

Often this connects to improper upgrades where owners are putting on different turbochargers or different injectors as well. And that causes the exhaust gas temperatures to generally climb up.

Overheating is a significant cause of diesel engine failures. High operating temperatures can damage engine components, such as the cylinder head, pistons, and valves. Common reasons for overheating include a malfunctioning cooling system, a blocked radiator, a faulty thermostat, or a lack of coolant. Proper cooling system maintenance and monitoring of engine temperatures are essential to prevent overheating issues.

Also just simply not watching gauges. Some well-used trucks will start getting higher engine temperatures. If unchecked, a lot of heat can build in the motor and cause premature head gasket failures.

Improper Upgrades

Ego might be one of the biggest downfalls of engine operators. Factory unauthorized repairs or upgrades, tuning and programming that don’t fit the engine and component parameters. We see everything from just a small failure to completely catastrophic. Generally, when they’re doing tunes, operators are putting on different turbochargers or different injectors as well. And that causes the exhaust gas temperatures to generally climb up.

We had a C15 Caterpillar engine in the shop where the owners used aftermarket programming to squeeze a little bit more power out of their engine. And then the engine creates a lot of carbon buildup. That carbon turns into an abrasive grit that could cause premature bearing failures and cylinder wall failures.

You could take your finger and just wipe on the inner front housing of the motor feel it on your fingers. This is all due to this aftermarket programming causing an inefficient burn in the cylinder from altered fueling rates and timing. We see this a lot, specifically on C15 engines.

Ultimately, there’s not a lot of evidence to go to aftermarket programming. And in the end, a lot of these customers are finding out that they’re spending tens of thousands of dollars. It’s costing people a lot of money, whereas you can build a quality engine within OEM parameters that’s going to perform better in the long run. We really love using PAI remanufacturing kits.

In Conclusion

There’s a plethora of things that take place that coincide with engine failure, but we often see that they relate to a few common things including improper break-in, maintenance and mechanical work and driver abuse.

Regular inspection, maintenance, and addressing issues promptly can help prevent these failures and extend the lifespan of diesel engines. Rely on the trusted technicians at Select Reman Exchange to provide quality service, parts and advice on all of your diesel engine needs.

Top Three Reasons to Select a Remanufactured Diesel Engine vs Used

When it comes to replacing a diesel engine, the two main options are often buying a used engine or investing in a remanufactured one. While used engines may seem like a cost-effective solution at first, they often come with uncertainties regarding their condition and reliability. On the other hand, remanufactured diesel engines offer several advantages that make them a superior choice. In this blog, we will explore the top three reasons to select a remanufactured diesel engine over a used one.

1. Reliability and Performance:

One of the key advantages of remanufactured diesel engines is the assurance of reliability and enhanced performance. Unlike used engines, remanufactured ones undergo a comprehensive process that involves dismantling, cleaning, inspecting, replacing worn-out components, and reassembling to meet or exceed original specifications. This meticulous refurbishment ensures that any faulty or worn-out parts are replaced, resulting in an engine that performs like new.

Remanufactured diesel engines are often backed by warranties, giving you peace of mind and protection against unexpected failures. Manufacturers stand behind their remanufactured engines, providing reliable support in case of any issues. This level of reliability and performance is seldom found with used engines, as their history, maintenance, and overall condition can be uncertain.

2. Cost-effectiveness and Longevity:

While used diesel engines may initially seem cheaper, they can potentially end up costing more in the long run. Used engines typically require additional expenses for inspections, repairs, and part replacements. On the contrary, remanufactured diesel engines offer a cost-effective solution by delivering better longevity and reduced maintenance needs.

Remanufactured engines undergo thorough testing and quality control processes to ensure they meet strict standards. This results in an engine that has been reconditioned with quality parts and components, often making it more durable than a used engine. By investing in a remanufactured engine, you minimize the risk of unexpected breakdowns and costly repairs, ultimately saving money over time.

3. Environmental Sustainability:

Selecting a remanufactured diesel engine also has significant environmental benefits. By choosing a remanufactured engine, you contribute to the reduction of waste generated from used engines. Instead of discarding an old engine, remanufacturing extends its life cycle, reduces energy consumption, and lowers carbon emissions associated with manufacturing a new engine.

At SRX, we never re-use a part that doesn’t pass strict inspections and isn’t machined back to OEM specifications, but often components can see new life, keeping them out of a landfill. This sustainable practice reduces the demand for new raw materials, conserves natural resources, and minimizes the overall ecological footprint. By opting for a remanufactured diesel engine, you actively participate in the circular economy and support environmentally conscious practices.

When it comes to replacing a diesel engine, the advantages of selecting a remanufactured engine over a used one are evident. Comparatively, remanufactured diesel engines offer superior reliability, performance, and longevity. They undergo our rigorous refurbishment process, ensuring they meet or exceed original specifications. While used engines may seem cheaper initially, the long-term costs and uncertainties associated with their condition and maintenance often make them a less favorable choice.

Ultimately, investing in a remanufactured diesel engine is a wise decision that brings peace of mind, cost-effectiveness, and a greener future.

And when failures occurred getting satisfaction through warranty coverage was not always easy. “When it came time to work with them for warranty purposes, it was very difficult to get any answers and the support we needed for using their products,” added Pratt.

The PAI Difference

We tried several PAI kits and our engine builders were very impressed with the components and packaging quality. 

Since that time we have purchased hundreds of kits and other parts from PAI for our engine builds and we have had tremendous success with their products. With that relatively high number of parts there is bound to be an issue and Pratt underscored how that’s when PAI continued to shine. “We have had only 2 engine failures that were attributed to a product issue, which PAI’s engineering team addressed immediately,” he said.

Caterpillar 3116 Facts: A Good Engine With A Bad Reputation

Caterpillar 3116 Remanufactured

A staple of the diesel engine industry for decades, the Caterpillar 3116 has a reputation problem, but that doesn’t mean it’s all bad. Here are the Caterpillar 3116 facts.

“3116 engines are often misunderstood. When properly tuned with the right tooling they can be a great and dependable engine,” said SRX General Manager Clay Conn.

This versatile and reliable engine delivers excellent performance and longevity, making it a popular choice for a wide range of applications. Whether you are looking for an engine for on-highway, industrial, or marine use, the Caterpillar 3116 is a great option that is sure to meet your needs.

Quality Where it Counts

One of the key reasons why the Caterpillar 3116 is so reliable is its design. This engine was designed with durability in mind, and it packs a number of features that help to ensure that it lasts a long time. For example the 3116 has a high-quality fuel system and a powerful turbocharger that help to ensure that it runs smoothly and efficiently.

Another reason why the Caterpillar 3116 is so reliable is its strong lower end. The most common failure we see from a 3116 engine is injector cup failure causing the customer to think they have a blown head gasket, or blowby/ring issue. It is very rare for us to see one of these engines with a spun bearing or broken connecting rod. The same crankshaft,  connecting rod, and block design was used in the 3126 and the C7 engine. Even in the higher horsepower applications of the C7 engine we rarely see a bottom-end failure. We had a Caterpillar 3126 come in with a thrown rod in 2019. Not a pretty sight.

Why Remanufactured from SRX?

At Select Reman Exchange, we are proud to offer remanufactured Caterpillar 3116 engines that are built to the highest standards of quality and reliability. In order to remedy the common failures of the 3116 engines we have a couple of extra steps to our remanufacturing process that ensures a quality product that will last a long time. In order to remedy the blowby and ring issues we install a new repair sleeve in the cylinder block in place of the original porous block casting. This ensures a lot less cylinder distortion under high-boost applications. The main reason for the premature ring failure is cylinder wall distortion under high cylinder pressure, high-boost applications. The distortion of the cylinder causes the rings to wear out prematurely. Our blocks are proven to last longer and be stronger with the new standard-size sleeves. During our remanufacturing process, in order to remedy the injector cup failures that are common in the 3116 engines, every cylinder head receives new upgraded injector cups and new seals. We also have an upgraded injector tip eliminating the injector tip O-ring, and replacing it with a steel ring integrated into the injector tip. This eliminates the need for the ever-failing injector tip O-rings and causes for a more confident seal in the cup.

Caterpillar 3126 HEUI Systems Replacement and Avoiding Fuel/Oil Cross Contamination

Caterpillar 3126

Follow our recommendations at SRX so you don’t make this common mistake when replacing a Caterpillar 3126 HEUI fuel system.

The C7/3126 HEUI (High-Pressure Electronic Unit Injection) system is a diesel engine fuel system used in heavy-duty vehicles and equipment. HEUI rely on high oil pressure to inject fuel into the engine. Cross-contamination in a HEUI system can occur when engine oil and diesel fuel mix, causing damage to the engine components and reducing performance. Causes of cross-contamination can include a failing injector, clogged oil passages, a damaged high-pressure oil pump, or a malfunctioning oil cooler.

Replace Systems as a Whole

When a component fails, we get asked to replace a single injector. Cutting corners here can cause more headaches down the road. We at SRX recommend replacing the Caterpillar 3126 HEUI system as a whole. 

HEUI systems are designed to deliver precise, accurate fuel metering, which results in improved engine performance and efficiency. This advanced fuel injection technology uses high-pressure oil to activate the injectors, instead of mechanical fuel pumps. The high-pressure oil is supplied by an engine-driven pump and is used to pressurize the fuel in the injectors, which atomizes the fuel and sprays it into the engine cylinders.

HEUI systems offer a number of advantages over traditional diesel fuel injection systems. For example, they are less complex and more reliable, and they require less maintenance. Additionally, they are capable of delivering high-pressure fuel injection, which results in better fuel efficiency and reduced emissions.

Benefits of Remanufacturing

It’s important to choose a high-quality remanufactured engine that has been thoroughly inspected and machined to OEM specifications. This will help ensure that the engine operates reliably, performs well, and is safe to use. Additionally, a remanufactured engine will often cost less than a new engine, making it a cost-effective solution.

If you’re looking for a reliable, high-quality remanufactured engine, look no further than Select Reman Exchange. Our technicians take pride in their workmanship and product quality, and we use trusted engine part manufacturers to supply us with all new piston and liner assemblies, bearings, gaskets, and seals.

Is The Caterpillar C15 The Best Heavy-Duty Engine Ever Produced?

Illustrating the block of a Caterpillar C15 diesel engine.

What features and history of the Caterpillar C15 help it compete for the title of best heavy-duty diesel engine? Many people have and continue to argue about it. However, it is not far from the truth. At Select Reman Exchange (SRX) we recognize the Caterpillar C15 as a legendary diesel engine. It’s known for its power, reliability, fuel efficiency, and versatility. Once and still is a very popular choice for many fleets and owner-operators for its performance and reliability.

The Caterpillar C15 diesel is a fantastic on-highway engine. Its ability to handle a wide variety of applications and environments make it a popular choice in other vocations.

The Formidable Caterpillar C15

By Chuck Pratt

Here at SRX, we have been remanufacturing the C15 engine for many years, as well as its predecessor the 3406E. To be transparent, we may be a little biased, because they are our favorite engines to build.

First produced in 1998 by Caterpillar Inc., the C15 “Single Turbo Engine” had numerous applications. C15s are used in construction equipment, agricultural equipment, marine applications, power generation systems and water pumping stations.

The C15 engine is known for its durability and reliability. It is also available in a variety of power ratings. Ranging from 375 horsepower to 625 horsepower from Caterpillar. Many Truck-Rodders push these engines upward of 1000+ horsepower with modifications. One of the key features of the Caterpillar C15 diesel engine is its rock-solid design for durability.

Laboratory tests and engine disassembly analysis, plus years of “actual proof”, have proven the C15 engines typically have a life span of one million miles with Cat’s recommended maintenance schedule. The engine from Caterpillar was built with high-quality materials and components, which helps to ensure long-lasting performance and durability. High-strength connecting rods and a robust crankshaft help to reduce wear and premature bearing failure.

Another key advantage of the Caterpillar C15 is its fuel efficiency. The engine has a number of features that help to reduce fuel consumption, such as an innovative fuel system and a fuel-efficient combustion process. These features help to reduce operating costs for fleets, companies and owner-operators who rely on it.

When Caterpillar designed the C15, it is no secret that it was entirely based on the 3406E.

The 3406E was a solid engine but it needed some improvements for reliability and emissions. One of those key changes that they made was the use of a higher-volume oil pump. With the higher volume oil pump, it obviously would supply better lubrication to the entire engine. But it also helps in reducing the engine operating temperature. In addition to the high-volume oil pump, they upped the volume of the water pump as well for better cooling capabilities. Another benefit Caterpillar added was better gaskets and seals. The “E” Models as they are commonly referred to, had issues with oil leaks and coolant leaks. Some of which were addressed by Cat in the later E-model engines, but not all. Thankfully Caterpillar addressed those issues with the release of the C15.

The first Caterpillar C15

The 6NZ engine serial number prefix was the first Caterpillar C15 diesel to be released. It was first built in July 1998 and enjoyed a lengthy production run until June 2005, with 99,900 engines made. To this day, the 6NZ is a very highly sought-after engine. It is very popular amongst owner-operators who are looking for an engine that will go 1 million miles without all the persnickety little failures that plagued other engine manufacturers from the same time period. The 6NZ C15 was reliable, efficient, and powerful.

In June of 2005, Caterpillar began production of the 9NZ prefix and continued production until February of 2009, with 18,500 engines produced.

Illustrating the block of a Caterpillar C15 diesel engine.

At the end of 2001 Caterpillar began production of the MBN prefix C15. It was produced until February 2003. The MBN is frequently referred to as the “bridge” engine. It was designed to bridge the gap between the pre-emissions 6NZ and the Twin turbo ACERT (Emissions) engines. A choked-out 6NZ was achieved through ECM programming with abysmal fuel mileage, low power, and high exhaust temperatures. It was so bad, that a lot of customers chose to swap the MBN out for a different engine. Until people began to realize that they could just change the ECM program. Nowadays, the MBN “mechanical” platform ranks a close 2nd to a 6NZ. It’s an option for a powerful and reliable engine for those discerning owners who want to keep their classic trucks going strong.


In an effort to meet the EPA 2004 Emissions regulations, Caterpillar released the ACERT. More commonly referred to as the twin-turbo. It stands for Advanced Combustion Emissions Reduction Technology.

The first version of the ACERT was released in March of 2003 with a Serial Number Prefix of BXS. The BXS C15 had a relatively short production span as it was last produced in December of 2004, with a total of 39,000 units made.

Later, in March of 2003 Caterpillar also released the MXS serial number prefix. This MXS version of the C15 incorporated the engine brake housing and the variable valve actuators into the same housing. Whereas on the BXS they were 2 separate housings. The MXS was the most popular version of the ACERT C15 with 100,000 units produced between March 2003 and July 2006. Next up was the NXS serial number prefix.

The NXS C15 is exactly the same as the MXS, with no differences at all. The change in the prefix was because Caterpillar ran out of serial numbers under the MXS prefix. Caterpillar produced 33,000 NXS C15 Engines from July 2006 until April 2009.

Finally came the SDP prefix C15.

First released in January 2005, the SDP was Caterpillar’s final attempt to keep up with the ever-changing EPA On-Highway emissions regulations. By incorporating a Diesel Particulate Filter (DPF system). They also redesigned the turbochargers to have a ball bearing supporting the turbo shaft instead of brass bearings. This made the cost of a turbocharger replacement much more expensive. They also changed the fuel injectors and redesigned the oil cooler setup. Production of the SDP C15 ended in March 2009, with a total of 22,700 engines made. From technicians’ and owners’ standpoint, the SDP is like COVID-19, most technicians don’t know how to diagnose and treat it, and the
owners don’t want it.

When parts and machines fail, choose SRX to be your go-to source for all your engine parts, and remanufacturing needs. Whether it be a boost pressure sensor, a failed oil cooler, or your engine needs to be completely remanufactured. Not only just the Mighty C15, but many others.
To all of us here at SRX, there is nothing sweeter and more rewarding than the first time a freshly remanufactured engine takes its first deep breaths. When air mixes with dinosaur juice, and lets out its first throaty roars of a new life, and shakes the ground … dang! That just gave me chills thinking about it.
