Additionally, it appears to be more prevalent on models manufactured after 2009, leading some to believe the multi-displacement system is to blame. This appears to be the most frequently occurring and serious cause of the Chrysler 345 HEMI engine ticking. Our primary focus is on faulty lifters and seized lifter rollers. What are some of the more frequent causes of 5.7 HEMI ticking?

However, other 5.7L HEMI owners have had to replace their entire engine due to engine ticks. Ticking on the 345 HEMI is an intriguing topic for a variety of reasons.Īccording to some, ticking is normal and has no effect on longevity or performance. We’re using a broad brush to describe the 5.7L engine ticking issues. Spoiler alert – this can occasionally be connected to other common issues. With that in mind, let us turn our attention to the issues raised previously. Additionally, engines are susceptible to potential problems that we will not discuss.Įarlier HEMI engines are becoming obsolete, and a variety of issues become acceptable on these older, high-mileage engines. Simply because we refer to these issues as “common” does not mean that they will affect every 5.7. Prior to delving into each of these common flaws in detail, a few additional general notes. The following are four of the most common 5.7 HEMI problems, in no particular order: We’ll go into greater detail about this as we go through each of the common issues below.

A few of the updates may increase the likelihood of certain problems on the 5.7L Eagle. However, as with any new technology, there are always kinks to iron out. This enables the engine to turn off four cylinders in certain circumstances, thereby improving fuel economy and emissions. Finally, Chrysler equipped the 345 HEMI with a multi-displacement system. However, the 5.7 Eagle employs a variety of manifold designs across its various models. Additionally, the 5.7 HEMI cylinder head is reworked to increase flow.Īdditionally, the intake manifolds are updated. This enables the engine to advance or retard cam timing for optimal performance across a broad range of RPMs. Several notable updates to the 5.7 HEMI include the following:Ĭhrysler refers to variable valve timing as variable camshaft timing. The engine has been renamed the 5.7 Eagle. The 5.7L engine underwent a revision in 2009 to improve emissions, fuel economy, and performance. If the 345 HEMI was a subpar engine, it’s unlikely Chrysler and Dodge would keep it in their flagship vehicles for so long. It’s easy to paint a bleak picture when discussing common engine problems.Īs such, we believe it is critical to remind ourselves and our readers that all great engines have issues. That, in our opinion, demonstrates the engine’s enormous success. Prior to that, let’s take a look at the various cars and trucks equipped with the 5.7 HEMI:Ĭhrysler’s 5.7-liter HEMI engine is deserving of respect for nearly two decades of powering a long list of popular cars and trucks. We believe it is necessary to lay out this information because certain updates are pertinent to this post about common problems. HEMI 5.7L InfoĪs previously stated, the Chrysler 5.7 engine received several updates over the course of its long life. This post discusses a few of the more common failures associated with the Chrysler 5.7L V8 HEMI. However, no engine is perfect, and the 345 HEMI is no exception. In general, it’s a dependable engine with strong performance and a pleasant sound. The 5.7 HEMI engine remains largely unchanged today, but it has been updated to increase power and fuel efficiency. It’s a long-running pushrod engine that made its debut in the 2003 Dodge Ram with 345 horsepower. The Dodge 5.7L HEMI engine is also referred to as the 345 HEMI due to its displacement of 345 cubic inches.
