The 6.4L Hemi engine in the 2017 Ram 2500 is a popular choice for its power and capability. However, some owners have reported issues with the camshaft and lifters, particularly in trucks with higher mileage. These concerns often surface online in forums and videos, leading potential buyers to question the engine’s long-term reliability. This article addresses these concerns, examining potential causes and exploring whether these issues are widespread or isolated incidents.
Common Concerns with the 6.4 Hemi Camshaft and Lifters
One of the primary concerns revolves around potential camshaft and roller lifter problems in the 6.4 Hemi, especially after exceeding 80,000 miles. Some theories attribute these issues to the camshaft’s high position within the engine. Prolonged idling and resulting lower oil pressure are often cited as contributing factors, potentially leading to inadequate lubrication.
Another theory suggests a connection between these problems and the Multi-Displacement System (MDS), a fuel-saving technology that deactivates four cylinders under light load conditions. Critics argue that MDS can cause uneven cylinder wear and insufficient oil delivery to the deactivated cylinders. Concerns exist regarding the engine’s reliance on consistently high oil pressure for proper lubrication, particularly during extended idle periods.
Are These Issues Widespread?
Online discussions can sometimes skew perceptions of reliability. A single problem reported by one owner can quickly escalate into a widespread concern, potentially creating a negative impression of the entire product line. Determining the true prevalence of camshaft and lifter issues in the 2017 Ram 2500 6.4 Hemi requires considering various factors.
While some owners have undoubtedly experienced these problems, it’s important to distinguish between isolated incidents and systemic defects. Many 6.4 Hemi engines have performed reliably without experiencing these specific issues. Factors such as maintenance practices, driving habits, and operating conditions can significantly impact engine longevity and the likelihood of encountering problems.
Mitigating Potential Problems
Some sources suggest that disabling the MDS system might help mitigate potential problems associated with uneven cylinder wear and oil distribution. However, it’s crucial to consult with a qualified mechanic or dealership technician before making any modifications to the engine’s operating system.
Proper maintenance, including regular oil changes with the recommended oil viscosity, is essential for ensuring optimal engine performance and longevity. Adhering to the manufacturer’s recommended maintenance schedule can help prevent potential issues and address any concerns proactively.
Conclusion: Assessing the Risk
While reports of camshaft and lifter issues in the 2017 Ram 2500 6.4 Hemi exist, it’s crucial to avoid generalizations. These problems don’t appear to be universally prevalent and may be linked to specific operating conditions or maintenance practices. Potential buyers should research thoroughly, consider individual vehicle history and maintenance records, and consult with trusted mechanics to assess the overall risk. Regular maintenance and responsible driving habits can contribute significantly to the engine’s longevity and reliability.
