Pure Diesel Power Introduces Technical Resource on 2019–2024 Ram 6.7L Cummins Roller Lifter Failure and Repair Options

Pure Diesel Power has released an updated technical resource detailing the roller lifter concerns identified in 2019–2024 Ram 6.7L Cummins engines. The publication outlines how factory-installed hydraulic roller lifters can experience premature wear under certain operating conditions, potentially leading to camshaft damage if not addressed.

According to the information presented on the Pure Diesel Power website, the issue is tied to the design and function of roller lifters, which rely on consistent lubrication and proper rotation to maintain contact with the camshaft. When this process is disrupted, the lifter may stop rotating, increasing friction and accelerating wear. Over time, this can result in visible engine symptoms such as ticking noises, performance loss, or internal damage.

The resource also identifies early warning signs that may help vehicle owners detect the issue before more extensive repairs are required. These indicators include abnormal valvetrain noise and changes in engine performance, which are commonly referenced in diesel service discussions and manufacturer-supported repair documentation.

As part of the published material, Pure Diesel Power outlines currently available repair paths, including the use of flat tappet conversion systems designed for 2019–2024 Cummins applications. These systems replace the factory roller lifter configuration with a flat tappet design, which removes the rolling component and reduces the likelihood of the specific failure mode associated with roller lifters. Product specifications and compatibility details referenced in the resource are based on manufacturer data for these conversion components.

The publication also includes fitment guidance to help ensure that components align with specific engine years and configurations. This information is intended to support diesel truck owners, technicians, and fleet operators in making informed maintenance and repair decisions.

A representative from Pure Diesel Power stated, “This resource was developed to provide clear, factual information on a commonly discussed issue within the Cummins community, along with documented repair options that align with current product availability.”

The technical material is now available through the Pure Diesel Power website and is intended for informational use by individuals researching Cummins engine maintenance and repair considerations.
