2014 Ram 1500 5.7 Hemi Cam And Lifter Kit

The 2014 Ram 1500, particularly those equipped with the iconic 5.7L Hemi engine, is a popular choice for truck enthusiasts. Known for its power and reliability, the Hemi can sometimes be susceptible to issues related to the camshaft and lifters. This article delves into the details of cam and lifter kits available for the 2014 Ram 1500 5.7 Hemi, covering their purpose, common problems, selection criteria, and installation considerations.

Understanding the Hemi Cam and Lifter System

The 5.7L Hemi engine utilizes an overhead valve (OHV) design, where the camshaft, located within the engine block, actuates the valves via pushrods and lifters. The camshaft is a rotating shaft with lobes that control the timing and duration of valve opening and closing. Lifters, also known as valve lifters or tappets, are small cylindrical components that sit between the camshaft lobes and the pushrods. As the camshaft rotates, the lifters ride on the lobes, transferring the motion to the pushrods, which in turn actuate the rocker arms and open the valves.

Proper functioning of this system is critical for engine performance and longevity. Worn or damaged camshaft lobes or lifter surfaces can lead to reduced engine power, rough idling, increased fuel consumption, and, in severe cases, engine failure.

Common Issues and Symptoms

Several factors can contribute to camshaft and lifter wear in the 2014 Ram 1500 5.7 Hemi. These include:

  • Oil Starvation: Inadequate lubrication due to low oil levels, clogged oil passages, or a failing oil pump can lead to rapid wear of the cam and lifter surfaces.
  • Poor Quality Oil: Using oil that does not meet the engine's specifications or failing to change the oil regularly can also accelerate wear.
  • Aggressive Driving Habits: Frequent high-RPM operation and excessive engine load can place increased stress on the camshaft and lifters.
  • Manufacturing Defects: While rare, manufacturing flaws in the camshaft or lifters can sometimes contribute to premature failure.

The most common symptom of a failing camshaft or lifter is a noticeable ticking or tapping noise emanating from the engine, often most pronounced at idle. Other symptoms may include:

  • Reduced engine power and torque
  • Rough idling and misfires
  • Increased fuel consumption
  • Check engine light illumination

Selecting a Cam and Lifter Kit

When replacing the camshaft and lifters in a 2014 Ram 1500 5.7 Hemi, it's crucial to choose a high-quality kit designed specifically for this engine. Several reputable manufacturers offer complete kits that include a camshaft, lifters, gaskets, and other necessary hardware. Consider the following factors when making your selection:

  • Camshaft Profile: Different camshaft profiles offer varying performance characteristics. A mild profile is suitable for everyday driving and towing, while a more aggressive profile may improve peak horsepower but sacrifice low-end torque. Match the camshaft profile to your intended use of the truck.
  • Lifter Type: Hydraulic roller lifters are the most common type used in the 5.7 Hemi. Ensure that the kit includes high-quality lifters that are compatible with the camshaft. Some kits offer performance lifters with improved durability and oiling characteristics.
  • Material Quality: Look for kits that use high-quality materials, such as billet steel for the camshaft and hardened steel for the lifters. This will ensure long-term durability and reliability.
  • Manufacturer Reputation: Choose a kit from a reputable manufacturer with a proven track record of producing high-quality engine components.

Installation Considerations

Replacing the camshaft and lifters in a 2014 Ram 1500 5.7 Hemi is a complex task that requires specialized tools and expertise. It is generally recommended that this work be performed by a qualified mechanic. The process typically involves:

  • Removing the intake manifold, valve covers, and other components to access the camshaft.
  • Carefully removing the old camshaft and lifters.
  • Installing the new camshaft and lifters, ensuring proper lubrication.
  • Setting the valve lash according to the manufacturer's specifications.
  • Reassembling the engine and performing a thorough engine test.

It's also essential to use the correct break-in procedure for the new camshaft and lifters. This typically involves running the engine at a moderate RPM for a specific period of time to allow the lifters to properly seat against the camshaft lobes. Always follow the manufacturer's instructions for the break-in procedure.

Conclusion

Addressing camshaft and lifter issues in your 2014 Ram 1500 5.7 Hemi requires careful diagnosis, informed parts selection, and meticulous installation. By understanding the components involved, the common causes of failure, and the available replacement options, you can ensure the continued performance and longevity of your Hemi engine. Remember to consult with a qualified mechanic for professional advice and installation if you lack the necessary experience and tools.
