LIQUI MOLY Diesel Purge
To preserve the original power and fuel economy of diesel engines, deposits should be removed from the injection system on a regular basis. LIQUI MOLY’s Diesel Purge is an additive for retaining optimal performance. Diesel Purge does as the name suggests: it gives diesel engines a thorough cleaning. It was developed to dissolve deposits and improve
Wear and Tear
When it comes to agricultural equipment, specifically tractors, many of them are used for decades upon decades due to durable, well-made engines and machinery that lasts. For this reason, agricultural equipment comes with a price tag – a big price tag. New tractors, ranging in size from compact to 4- and 6-cylinder engines, can cost
NADM/DIESEL Motorsports 2014 Schedule Set
The National Association of Diesel Motorsports is in its eighth year of providing Sanctioned diesel sled pulling and drag racing events across the United States. Diesel motor sports and NADM has grown quickly with events now all over the country. Many state, regional clubs/associations and diesel promoters are putting diesel events in many different rural
Building on Cummins B-Series
Changes from the 5.9L to the 6.7L Engine When you think about a Dodge truck, what is the first thing that comes to mind? I will give you a hint: Cummins. Dodge introduced the B-series Cummins engine in the Dodge truck in 1989. It’s not like they had to convince consumers that the Cummins engine
Venturing Into GM Duramax Diesel Service
There are five generations of the Duramax engine. The best way to identify the generation is by the year, model and the RPO (regular production option) code. Back in the 1990s, GM wasn’t making too many waves in the diesel truck market. The 6.2L and 6.5L engines had been around for sometime, but they were no match
Diesel Exhaust Fluid Not So Bad
I often hear comments from people about a strange and mysterious fluid called DEF (Diesel Exhaust Fluid) that is used in some late-model diesel trucks. Many owners of these newer diesel-powered vehicles don’t know what DEF is or why they have a separate tank or even how often to add the stuff. And what exactly
Performance Diesel: The New Hot Rods
With all of the bolt-on diesel components that are available on the market these days, why would you get into offering performance engine rebuilds for the diesel market? I’m sure you are asking yourself this question every time you get a call from someone with a diesel engine asking how they can get more power. But believe
Performance Diesel: Turbos & Tuning
There is nothing more fast and furious than the roar of a turbo engine when it is finely tuned and performing efficiently on all levels. Whether pulling gear with the diesel truck or revving the street hot rod, making the most out of the turbo is crucial to most engine builders. As the consumer’s appetite
Super Comp Drag Racing
There are no rules for engine size, but engine builders should look to build for consistency in this class What does it take to build a winning engine for Super Comp drag racing? The Super Comp drag racing class runs on a 8.90 time limit, with essentially no rules regarding engine displacement, carburetion or type
Ready for a Diesel Resurgence?
Diesel engine building will soon see an increase in numbers – very soon! Why do I say that? In an effort to eliminate smoking engines and reduce emissions, the EPA came down hard on tuner manufacturers just a few months ago, issuing warning/cease notices on diesel particulate filters (DPF) and EGR delete tunes/kits.
Warranties Are Everyone’s Problem
Warranty! The word shouted from the other end of the telephone can cause some people to wake up screaming in the night. It seems that warranty problems grow exponentially – once one comes in they seem to multiply just in time to ruin a good month’s sales results. Who’s Fault Is It? Usually it’s yours
Diesel Injection Components
For some time now, most of the development in diesel technology has been aimed towards making the engines environmentally-friendly. But as diesel engines have become cleaner, the power levels have also increased. This is somewhat backward to what the country went through in the ’70s with gasoline engines. The problem back in the ’70s was
Heavy-Duty Coolant Options
While the fundamental duty of engine coolants has not changed – they must transfer excess heat and offer freeze and boiling protection, plus corrosion and liner protection – modern coolants must transfer more heat than in the past, largely due to new emissions systems. When considering the energy consumed to power a heavy-duty diesel
E=MC2 and Diesel Injection Equals MM3
When diagnosing and repairing today’s modern diesel engines, you often trust your scan tool to give you answers. But what do you do when it gives you more questions? We decided to investigate a mystery that has always eluded us until now. As diesel engines have become more electronically controlled, I have been baffled
Understanding the Importance of Common Rail Injection to Today
It seems that there have been some improvements in diesel injection technology that have allowed some “clean-up” work on the diesel exhaust system, and I think we all can appreciate the change. Even though some may feel the need to complain about the increased use of electronics and how the government is cracking down by

Brief Overview of Caterpillar C7 Engines
This popular engine can often be found in on-highway trucks, and also in off-highway applications such as loaders, skidders, excavators, motor graders, and industrial and marine units. It is actually a 7.2 liter (439 cid) engine with a 4.33? bore (110mm) and 5.0? stroke (127mm). Note: This engine was also covered in more detail in
Understanding and Profiting From the Caterpillar C7
I believe society naturally directs the outcome of its environment: if someone manages a quality independent automotive repair shop, they will always be looking for ways to increase their education and specialty tools as technology changes. In order to take care of their customers when the warranty runs out and they no longer visit the
7 Shop Survival Tips
Ford 5.0L/302 "Cobra" Cams Problem: Ford made a limited number of the Mustang Cobras with a "super-high-output" 5.0L in ’93, ’94 and ’95. They all had a unique roller cam (p/n F3ZZ-6250-A) that can be identified by the "GT" stamped on the barrel, right behind the distributor gear (see Figure 1, at right). This cam
Understanding
The light turns green and the truck bellows out a plume of black smoke and in a flash all you see are the taillights. You’re struck that diesel trucks have really made an improvement over the past fifteen years. It’s amazing when you realize that a Corvette would have a hard time keeping up with
