Split injector tips are often caused by dry starts and there is also a theory about water in the fuel causing this. Splitting the injector tips are primarily caused by improper fuel system bleeding after servicing the fuel system, including a filter change or other issues where the injectors stop getting fuel. Because “dry starts” cause…
The Cummins “53” Block was used in Cummins 24 valve ISB diesel engines from 1998.5-2002. Manufactured by Brazilian company, TUPY. The “53” block casting has thin water jacket walls that are susceptible to cracking. With coolant cavitation, corrosion, coolant pressure in the block, frequent or heavy towing they may crack, causing a loss of coolant. Failing to…
The 6.7L Power Stroke is the first medium duty diesel designed and built by Ford. During design, Ford engineers codenamed this engine “Scorpion” due to the exhaust manifold and turbo being mounted in the engine’s “valley”. Ford Motor Company has done an amazing job with the 6.7 Liter Power Stroke engine, which has impressive performance,…
There are several reasons why diesel engines in passenger cars and light trucks haven’t gained as much popularity in the U.S. as in other countries. For the most part it is due to misinformation or ideas based on much older technology. Today’s diesel engines are more efficient, more powerful, more durable, and cleaner running than…
Why Do Diesel Fuel Injectors Fail? There are two major causes of diesel fuel injector failure associated with the properties of the fuel itself: excess wear and deposits. 1) Common Reasons Diesel Injectors Fail: Excessive Wear One mode of injector failure is excess wear. Prior to 2006, diesel fuels in the United States contained relatively…
Diesel Fuel System Maintenance If all diesel engines had nearly identical fuel system trouble, diagnosis and maintenance procedures could follow a general pattern. But, with the exception of similar fuel tanks and basic piping system, diesel fuel systems differ considerably. Consequently, each engine manufacturer recommends different specific maintenance procedures. However, the tune-up and maintenance procedures…
The diesel fuel injection system is a major component of a properly operating engine. An engine out of adjustment can cause excessive exhaust smoke, poor fuel economy, heavy carbon buildup within the combustion chambers, and short engine life. The diesel engine is known as a CI (compression ignition) engine, while the gasoline engine is known as a…
The Cummins 5.9L “B-Series” diesel engine was produced from 1984 up until 2007. First generation versions were named the 6BT but also commonly referred to as the 12v, or 12-valve. Each cylinder had 2 valves, hence the name 12-valve. Midway through 1998, the 6BT was replaced with the ISB, which stands for “Interact System B”….
If you Google P1693, you will probably see something that reads “Turbo Charge Control Circuit Malfunction”. However, on Cummins turbo diesel engines, this code has nothing to do with the turbocharger. P1693 is considered the “companion code”. It is triggered when the powertrain control module (PCM) detects a code that us not actually associated with the…
