2016 Ram 1500 5.7 Hemi Cam And Lifter Kit
The 2016 Ram 1500, particularly those equipped with the legendary 5.7L Hemi V8, remains a popular choice for truck enthusiasts. Its blend of power, capability, and relative simplicity makes it a compelling option, both new and used. However, a known weakness in these engines, particularly as they age and accumulate mileage, is the potential for camshaft and lifter failure. This article delves into the nuances of the 2016 Ram 1500 5.7 Hemi cam and lifter replacement, offering insights for owners, enthusiasts, and professionals alike.
Understanding the Issue: Hemi Cam and Lifter Woes
The 5.7L Hemi is renowned for its robust performance. However, its design incorporates a roller lifter system riding on a cast iron camshaft. Over time, several factors can contribute to premature wear and eventual failure:
- Lubrication Issues: Inadequate oil changes or the use of incorrect oil can lead to accelerated wear. The MDS (Multi-Displacement System), designed to improve fuel economy by deactivating cylinders, places additional stress on specific lifters. This system needs optimal oil flow to function correctly, so any sludge or blockage will have negative effects.
- Metal Fatigue: Continuous stress and heat cycles can cause the hardened surface of the lifter rollers or camshaft lobes to fatigue and eventually fail.
- Manufacturing Defects: While less common, manufacturing imperfections in the lifters or camshaft itself can predispose the components to early failure.
Symptoms of a failing camshaft and lifter can include a ticking or knocking noise emanating from the engine (often described as the "Hemi tick"), a loss of power, rough idling, and potentially even misfires detected by the engine's computer. Ignoring these symptoms can lead to catastrophic engine damage.
Choosing the Right Cam and Lifter Kit
When the time comes for replacement, selecting a high-quality cam and lifter kit is crucial. Several reputable aftermarket manufacturers offer solutions designed to address the known weaknesses of the original equipment. Consider the following factors when choosing a kit:
- Lifter Design: Opt for lifters with improved roller bearings and robust construction. Some aftermarket options feature enhanced oiling pathways to ensure adequate lubrication.
- Camshaft Material: High-quality steel camshafts with hardened lobes offer increased durability and resistance to wear. Look for induction-hardened or billet steel options.
- Kit Contents: Ensure the kit includes all necessary components, such as lifters, camshaft, valve springs, retainers, locks, seals, and gaskets. Some kits also include a new timing chain and gears, which is highly recommended for a complete overhaul.
- Reputation of the Manufacturer: Stick with reputable brands known for producing high-quality engine components. Do your research and read reviews from other 5.7 Hemi owners.
Popular brands for 2016 Ram 1500 5.7 Hemi cam and lifter kits include Melling, Comp Cams, and Edelbrock. Consult with a qualified mechanic or engine builder to determine the best option for your specific needs and driving style.
The Replacement Process: A Task for Professionals
Replacing the camshaft and lifters on a 2016 Ram 1500 5.7 Hemi is a complex and labor-intensive job that requires specialized tools and expertise. It's generally not recommended for inexperienced DIYers. The process involves:
- Removing the intake manifold, cylinder heads, and front engine cover.
- Carefully removing the old camshaft and lifters.
- Thoroughly cleaning and inspecting all components.
- Installing the new camshaft and lifters, ensuring proper lubrication and alignment.
- Replacing any worn or damaged components, such as valve springs and seals.
- Reassembling the engine and performing necessary adjustments, such as valve lash.
Improper installation can lead to serious engine damage. Therefore, entrusting the job to a qualified mechanic with experience working on 5.7 Hemi engines is highly advisable.
Preventative Maintenance: Extending Engine Life
While camshaft and lifter failure can occur even with diligent maintenance, proactive measures can significantly extend the life of your 2016 Ram 1500 5.7 Hemi:
- Regular Oil Changes: Adhere to the manufacturer's recommended oil change intervals and use a high-quality synthetic oil that meets Chrysler's specifications.
- Proper Oil Level: Regularly check the oil level and top off as needed.
- Avoid Prolonged Idling: Excessive idling can contribute to oil sludge and increased engine wear.
- Consider an Oil Additive: Some owners swear by oil additives designed to reduce friction and protect against wear, although their effectiveness is debated.
By understanding the potential issues, choosing the right replacement parts, and practicing proper maintenance, you can ensure the long-term reliability and performance of your 2016 Ram 1500 5.7 Hemi.
