Drew Pumphrey, owner of D&J Precision Performance, weighs in on stock vs. performance work in the shop and finding a balance between the two.
Not only does oil lubricate as a means of controlling friction but also has to control contamination, temperature, corrosion, shock, wear, and pressure. Oil analysis is the only true way to put a set of “eyes” on the engine’s condition and the condition of the oil as to when it should be changed.
Challenges of Change – 10 Things You’ll Learn From Oil Analysis and How They Affect Engine Condition
For most consumers, a preventive maintenance program for their automobile consists of nothing more than an oil change. While a regular oil change is very important, the most critical part of changing the oil is to know when to change the oil. The interval of the oil change is often dictated by one of two
Modern diesel engine platforms offer a great source of power potential regardless of the manufacturer. I suppose that is why the mid-size diesel truck has become so popular among the younger generation. Take an engine that already makes power and find ways to make more. Turbocharged diesel engines have a huge amount of power gains
When working on Cummins engines that are Common-Rail injected (2003 MY and up), you may experience diagnostic trouble code P0251. The customer complaint is usually a loss of power when the truck is in a hard pull, especially when towing. I see this quite often at the shop. This code can be somewhat chronic if
For most consumers, a preventive maintenance program for their automobile consists of nothing more than an oil change. While a regular oil change is very important, the most critical part of changing the oil is to know when to change the oil.
Think about the diesel engine over the last 30 years. From a rattling bucket of bolts that often got a frown from people it’s become a highly sought-after engine among the younger high school generation. Who would ever have imagined that one?
Why should you offer more when rebuilding a diesel engine? Because any shop can rebuild the OEM block or buy a direct replacement. However, rebuilding a diesel engine with slight power modifications will get you more customers and offer you higher profits because of the modifications made that not everyone can do or has the knowledge to do.
I often wonder why so many owners aren’t more concerned with the condition of the coolant in their engines. I don’t know if it is the price of the coolant that tends to scare them away or what. Most mid-size truck diesel engines take approximately six gallons of coolant to fill the system. That would
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
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
