MOST COMMON PROBLEMS OF DODGE / RAM 2007.5-2018 6.7L 24V

Common Problems of Dodge/Ram 2007.5-2018 6.7L 24V Engines

While the 6.7L Cummins is a robust engine known for its durability, it’s not without its quirks. Many issues stem from the emissions equipment, a far cry from the simpler days of earlier diesel models. Understanding these common problems can help you maintain your vehicle’s performance and longevity. Let’s dive into the specifics 6.7L Cummins problems.

Understanding 6.7l cummins problems

Clogged Diesel Particulate Filter (DPF)

One of the most prevalent issues faced by the 6.7L Cummins is a clogged diesel particulate filter, particularly in models manufactured before 2013. Initially, these engines operated without diesel exhaust fluid (DEF), which meant they had to run rich to manage NOx emissions. This rich running contributed to increased soot production, leading to quicker DPF clogging.

The severity of DPF issues prompted Dodge and Ram to implement several PCM updates to alleviate the problem. With the introduction of SCR and DEF in 2013, newer models experience far fewer DPF-related concerns. However, higher-mileage trucks may still encounter clogging, resulting in power loss, long cranking times, fault codes, and reduced engine performance. If you’re facing these symptoms, it may be time to explore options for cleaning or replacing your DPF.

Fuel Injector Issues

Fuel injector failures are another common problem with this engine. Poor fuel quality or contamination can lead to malfunctioning injectors, resulting in rough idling, misfires, or reduced power. Left unchecked, it can cause long-term damage to your engine. ABCO Diesel offers comprehensive injector diagnostics, cleaning, and replacements to ensure your truck runs smoothly and efficiently.

EGR Valve and Cooler Failures

The Exhaust Gas Recirculation (EGR) system in the 6.7L Powerstroke, while more reliable than in older models, can still experience significant soot buildup over time. This can cause the EGR valve or cooler to fail, leading to performance issues and even engine damage. Our team at ABCO Diesel specializes in cleaning or replacing faulty EGR components to keep your engine running cleanly and efficiently, preventing more serious issues down the line.

Cracked Exhaust Manifold

Another frequent issue in the 6.7L Powerstroke is the cracking of the exhaust manifold, especially in earlier models. This can lead to exhaust leaks, increased emissions, and a loss of engine power. If your truck’s exhaust manifold is showing signs of wear or damage, ABCO Diesel can replace it with high-quality, durable parts that ensure a proper seal and restore your engine’s performance.

Injection Pump Failures

The Achilles heel of the 2011-2016 6.7L Powerstroke is its Bosch CP4.2 injection pump, which is prone to failure due to metal-on-metal contact caused by air in the system. When this pump fails, it can send metal shavings throughout the fuel system, causing extensive and expensive damage. ABCO Diesel is equipped to handle these repairs, including replacing the injection pump and cleaning the entire fuel system to prevent further contamination.
