Table of Contents

What years are affected by the Hemi tick?

The Hemi tick issue affects certain Chrysler, Dodge, Jeep, and RAM models with Hemi V-8 engines from 2014 to 2022. The lawsuit lists several affected models, including the 2014-2022 Chrysler 300 and the 2014-2022 Dodge Challenger.

It’s important to understand that the lawsuit doesn’t necessarily mean every vehicle within these model years has the Hemi tick issue. This is a broad range of models with varying engine configurations and build dates. To determine if your specific vehicle is affected, you should check with your local dealership or contact Chrysler directly. You can find the vehicle identification number (VIN) on your vehicle’s registration or title, which you can then use to search for any open recalls or technical service bulletins. It’s worth noting that these issues can be difficult to diagnose, and it’s always a good idea to consult with a professional mechanic to ensure your vehicle is functioning correctly.

How much does it cost to fix a Hemi lifter tick?

You can expect to spend between $1,000 and $2,500 to have a professional replace a Hemi lifter.

Replacing a lifter is a common repair for Hemi engines, and the cost can vary depending on the specific model, the severity of the problem, and the location of the repair shop. The cost can also be influenced by the availability of parts and the labor rates charged by the mechanic. Keep in mind that some repairs can be more extensive, such as needing to replace the entire camshaft, and this can dramatically increase the cost of the repair.

It’s important to understand that a lifter tick is a common issue that is often caused by worn-out lifters. As these lifters wear out, they can cause a ticking noise in the engine. A lifter tick is a symptom of a problem and not the problem itself. You may hear a clicking or tapping sound coming from the engine. A lifter tick is typically a more consistent sound, that you can hear, even when your engine is warming up.

It’s important to note that a lifter tick can also be a sign of other engine problems. If you notice a lifter tick, it’s essential to take your vehicle to a qualified mechanic for diagnosis. This will help determine the cause of the lifter tick and ensure the correct repair is performed. If you don’t address the issue promptly, it can lead to more significant engine damage.

How bad is a lifter tick?

Let’s talk about that lifter noise you’re hearing. It’s important to get it checked out, but don’t panic just yet. In most cases, a lifter tick won’t cause catastrophic damage right away.

If the tick is mild, it might just be a worn-out lifter that needs replacing. This is often a relatively straightforward repair. However, if the tick gets louder or changes in sound, it could indicate a more serious problem.

In a worst-case scenario, a badly worn lifter could break apart and damage your camshaft or even your entire engine. This is why it’s essential to address the issue promptly. Catching a lifter problem early can save you a lot of headaches and expensive repairs down the road.

Think of it like this: A lifter tick is like a little warning light on your engine. It’s telling you that something needs attention. The sooner you take action, the less likely you are to face major issues.

Here’s a little more about why lifter ticks happen and how to tell if they’re serious:

Lifters, also known as hydraulic lifters, are small components that sit between the camshaft and the pushrods. Their job is to maintain a consistent gap between the camshaft and the valves. This gap is crucial for proper valve operation and engine performance.

When a lifter wears out, it can’t maintain the proper gap, leading to a “ticking” sound. This sound occurs because the lifter isn’t keeping the valve open for the correct amount of time, causing the valve to “tick” as it closes.

Here are a few things that can cause lifter problems:

Old age: Like any mechanical part, lifters can wear out over time.
Insufficient lubrication: Lack of oil can cause the lifter to wear down prematurely.
Dirty oil: Clogged oil passages can prevent oil from reaching the lifters properly.
Improper valve adjustment: If the valves are not adjusted correctly, it can put extra stress on the lifters.

How to tell if a lifter tick is serious:

While a lifter tick can be worrisome, it’s not always a cause for immediate panic. Here’s what to look for:

Loudness and frequency: A loud, consistent ticking sound is more likely to indicate a serious problem.
Location: A lifter tick usually originates from the top of the engine, but it can be difficult to pinpoint the exact location without a mechanic’s inspection.
Engine performance: If you notice a decrease in engine power or a rough idle, it’s a good sign that the lifter problem is more serious.
Oil pressure: Low oil pressure can be a sign of a problem with the lifter or the oiling system.

Remember, the best way to determine the severity of a lifter tick is to have your vehicle inspected by a qualified mechanic. They can listen to the sound, inspect the lifters, and determine if a repair is necessary. Don’t wait until the problem gets worse. It’s always better to catch issues early, before they cause significant damage.

How do you stop a Hemi tick?

Let’s talk about how to potentially prevent or address a Hemi tick.

You might be able to resolve a Hemi tick by cleaning the engine. Dirt or debris can sometimes cause the tick. Using a fuel and oil additive can help clean your engine.

Switching to a higher-quality fuel and higher-quality oil can also improve the situation. You could try switching to high-quality synthetic oils to help prevent the Hemi tick. Many people find that using synthetic oil helps with engine longevity and can help reduce the chances of experiencing this issue.

Here’s a bit more about why these steps might help:

Fuel and Oil Quality: A dirty engine can lead to a Hemi tick. Using high-quality fuels and oils can help keep your engine clean and running smoothly.
Synthetic Oils:Synthetic oils offer several advantages over conventional oils. They are generally more resistant to breaking down under high heat and pressure, which is essential for modern high-performance engines. This can help prevent wear and tear on engine parts, which could contribute to a Hemi tick.

Remember: While these tips might help prevent or reduce a Hemi tick, it’s always best to consult a qualified mechanic if you suspect an issue with your engine. They can diagnose the problem accurately and recommend the best course of action.

Is 5.7 a true Hemi?

Lee says everything else, in terms of the valvetrain arrangement and the shape of the chamber, is a true Hemi. Of course, it’s not as large as the old Hemi. With 345 hp, the 5.7-liter Hemi V-8 boasts 100 more horsepower than the 5.9-liter Magnum V-8.

The term “Hemi” refers to a specific type of combustion chamber design. A hemispherical combustion chamber (Hemi) is a type of combustion chamber with a hemispherical shape. This design allows for a more efficient combustion process, resulting in more power and torque.

While the 5.7-liter Hemi doesn’t have the same massive proportions of its predecessor, the 426 Hemi, it still shares the same fundamental Hemi design. The 5.7-liter Hemi features a hemispherical combustion chamber, a valvetrain arrangement with two valves per cylinder, and a cross-flow design that allows for better airflow.

The 5.7-liter Hemi is a powerful and efficient engine. It’s no wonder that it’s been a popular choice for many years.

What is the bad year for the 5.7 Hemi?

The 5.7L Hemi is known for its power and reliability, but like any engine, it has its share of challenges. While most model years perform well, 2011 and 2012 stand out as years with a few more reported issues, particularly for Ram pickups.

2012, in particular, had some problems with the 5.7 Hemi engine in Ram trucks. The most common issue reported was with the timing chain. This crucial part ensures the proper timing of the engine’s valves, and if it fails, it can lead to significant engine damage. While the issue itself isn’t unique to 2012, it seemed to be more prevalent in that model year, leading to some frustration among owners.

The timing chain issue in the 2012 Ram trucks stemmed from a manufacturing defect. The chain itself was prone to premature wear, which could lead to stretching and eventually breaking. This could result in a variety of symptoms, including a rough idle, misfires, and even engine failure.

If you’re considering purchasing a used Ram truck with a 5.7 Hemi engine, it’s wise to be aware of this potential issue. While not every 2012 Ram with a Hemi will experience this problem, it’s something to keep in mind during your inspection process. Look for signs of a faulty timing chain, such as excessive noise or vibration during startup, and make sure to get a thorough inspection from a qualified mechanic.

Why does my 2010 5.7 GC have a hemi tick?

You’re right, that hemi tick on your 2010 5.7 GC is a common problem. Since you’ve already ruled out the exhaust manifold, it’s likely a lifter issue. The Eagle Head VVT motors are known for this, and it can be a little nerve-wracking, but let’s break down what’s happening.

Those lifters are basically little pumps that push on the camshaft to open the valves, and they’re filled with oil. Over time, the oil can get dirty or break down, causing the lifter to stick or make that ticking noise. It’s important to understand that a hemi tick doesn’t always mean immediate engine damage. But, if left unaddressed, it can lead to issues down the line.

Here’s what can happen:

Worn Camshaft Lobes: If the lifters are sticking, they can wear down the camshaft lobes, which are the parts that the lifters push on.
Valve Damage: Worn camshaft lobes can cause the valves to open and close improperly, which can lead to reduced engine performance, misfires, and even valve damage.
Engine Failure: If the valve damage is severe enough, it can lead to engine failure.

How long before the cam is damaged? That’s tough to say. It depends on how bad the hemi tick is, how often you drive, and how well you maintain your engine. The good news is that there are things you can do to help prevent this from happening.

Regular Oil Changes: Using the correct oil and changing it regularly is crucial.
Oil Additives: Some oil additives are formulated to help clean and lubricate the lifters.
Engine Flush: If the tick is severe, an engine flush might help remove sludge and debris that is clogging the lifters.

Remember: If you are concerned about the hemi tick, it’s best to have your car inspected by a qualified mechanic. They can diagnose the problem and recommend the best course of action. It’s always better to address potential problems early on than to wait until they become major issues.

Why does my Hemi tick a lot?

Let’s talk about those ticking Hemi engines! You’re not alone; many Hemi owners experience this. A lot of the ticking you hear might come from the PCV and/or the EGR valve.

The PCV (Positive Crankcase Ventilation) system helps vent gases from the crankcase. If this system isn’t working properly, it can lead to a ticking sound. Similarly, the EGR (Exhaust Gas Recirculation) system, which helps reduce emissions, can also contribute to ticking noises if it’s not functioning correctly.

Some Hemi owners have reported that disabling the EGR unit using a device like a Predator helped reduce the ticking. However, remember that disabling an emissions system might not be legal in your area, so check your local regulations before doing this.

If you’re looking for a more customized solution, you might want to explore Quantum Products. These guys are experts in Hemi engine tuning and offer custom blends specifically designed for your engine. It’s worth looking into their services if you’re serious about optimizing your Hemi’s performance and addressing that ticking noise.

Here’s a deeper dive into the PCV and EGR systems and how they might contribute to ticking noises:

PCV System: The PCV valve is responsible for drawing crankcase gases into the intake manifold. When the PCV valve malfunctions, it can either allow too much or too little airflow, leading to a ticking sound.
EGR System: The EGR valve regulates the flow of exhaust gas back into the intake manifold. This process helps reduce combustion temperatures and emissions. However, if the EGR valve gets stuck open or closed, it can lead to a ticking sound.

The good news is that both the PCV and EGR systems are relatively straightforward to inspect and repair. If you suspect either system is contributing to the ticking, you might want to check for worn or damaged components, and consider replacing them with new ones.

Remember, there are other potential sources for ticking noises in your Hemi, so it’s always a good idea to consult with a mechanic if you’re unsure of the cause. A professional can pinpoint the exact source of the ticking and recommend the best course of action for you.

Does my Hemi have lifter tick?

It’s great you’re checking on your Hemi! Based on the year of your engine, it’s unlikely you’re experiencing lifter tick. Lifter tick became a more common issue in Hemi engines starting in 2009. Before that, dropped valve seats were a more common concern, especially when the engine got hot.

Let’s delve a bit deeper into what causes lifter tick and why it’s not as likely in your pre-2009 Hemi:

Lifter Tick: The Basics

Lifter tick is a noise that often sounds like a tapping or clicking coming from the engine. It’s caused by the lifters, which are small components that help open and close the engine’s valves. When a lifter isn’t working properly, it can make a ticking sound.

Why Your Pre-2009 Hemi Might Be Different

The Hemi engines produced before 2009 used a different design for their lifters. These earlier lifters were more robust and less prone to the issues that caused lifter tick in later models.

However, your engine could still experience other noises, and it’s always best to consult with a mechanic if you hear something unusual. They can diagnose any potential issues and help you maintain your Hemi in top condition.

Do Hemi ticks increase the life of your engine?

Let’s talk about Hemi ticks and how they might affect your engine’s lifespan. While addressing Hemi tick noises can contribute to a smoother and quieter driving experience, it’s important to understand that Hemi ticks themselves don’t directly shorten your engine’s life.

Hemi ticks are a common sound associated with Chrysler’s Hemi engines, particularly the 5.7L and 6.4L models. They are often described as a “ticking” or “tapping” sound coming from the valve train. This sound is usually caused by a combination of factors, including the design of the valve train, the type of oil used, and even the weather.

While Hemi ticks can be annoying, they aren’t necessarily a sign of a serious problem. However, if you’re experiencing a loud or persistent Hemi tick sound, it’s always a good idea to have your engine inspected by a mechanic. They can help diagnose the cause of the sound and ensure that your engine is running properly.

In some cases, using a high-quality oil specifically designed for Hemi engines can reduce the severity of Hemi ticks. Additionally, some mechanics recommend using a specific type of oil additive that can help quiet down the valve train. However, it’s essential to consult with a professional before adding any additives to your engine.

Remember, addressing Hemi tick noises can provide a more pleasant driving experience and potentially reduce wear and tear on your engine’s valve train. But, they don’t directly impact the overall life expectancy of your engine.

Why Does My 5.7 Hemi Tick: Causes And Fixes

Alright, let’s dive into the world of 5.7 Hemi ticks. You’ve got a rumble under the hood, and you want to know why.

Let’s face it, a ticking engine can be pretty unsettling. It’s like a little voice whispering, “Hey, there’s something wrong with me!” But don’t panic just yet. We’ll break down the common culprits behind that ticking sound and hopefully put your mind at ease.

The Usual Suspects

First things first, it’s crucial to understand the “HEMI” in “5.7 HEMI”. HEMI stands for “hemispherical combustion chambers”. These chambers are a distinctive feature of the Chrysler 5.7-liter engine, known for their power and torque. But, like any engine, they can develop issues, and sometimes, those issues manifest as a ticking sound.

1. Lifter Tick

Now, the most common reason for that ticking sound is “lifter tick”. Think of “lifters” as tiny hydraulic jacks that raise and lower the “pushrods” that connect to your “camshaft”. These lifters need oil pressure to function properly. If the oil pressure is low, or if the lifters themselves are worn out, you’ll hear that telltale ticking sound.

“Lifter tick” is usually most noticeable when the engine is cold.

* As the engine warms up and the oil pressure increases, the ticking may fade away.

2. Valve Tick

Another possibility is “valve tick”. “Valves” are the gates that control the flow of air and fuel into the combustion chambers. They’re controlled by the “camshaft” through the “pushrods” and “lifters”.

If the “valve stems” or the “valve guides” wear out, you can get a ticking noise. This ticking often sounds like a rapid tapping or clicking, and it might change with engine speed.

3. Timing Chain Tick

If your “timing chain”, which synchronizes the “camshaft” with the “crankshaft”, is worn or stretched, it can create a ticking noise. This ticking is usually a constant, rhythmic sound, and it might get louder as the engine revs up.

4. Other Culprits

While lifter tick, valve tick, and timing chain issues are the most common culprits, other factors can cause a ticking noise in your 5.7 HEMI.

Loose rocker arm: These arms connect the “pushrods” to the “valves”. A loose rocker arm can create a ticking sound, especially at high RPM.

Bad spark plug: If a spark plug is loose or faulty, it can cause a misfire, which can sometimes sound like a ticking noise.

Engine knock: This is a much more serious issue caused by detonation or pre-ignition. It can produce a metallic pinging or rattling sound, which is distinct from the ticking associated with lifters, valves, or timing chains.

What to Do When You Hear That Tick

First, don’t panic! As we mentioned, the sound of ticking can be caused by a variety of factors, and not all of them are serious. However, it’s essential to investigate the cause and address it promptly to prevent further damage to your engine.

1. Get it Checked Out

The best way to figure out why your 5.7 HEMI is ticking is to take it to a trusted mechanic. They can listen to the sound, check the oil pressure, inspect the timing chain, and examine the lifters and valves. A good mechanic can pinpoint the cause and recommend the appropriate solution.

2. DIY Diagnosis (with Caution)

If you’re mechanically inclined and feel comfortable tackling some basic troubleshooting, you can try to narrow down the cause of the ticking yourself. Here are a few things you can try:

Check the oil level: Make sure the engine has enough oil. Low oil levels can contribute to lifter tick.

Listen closely: Try to pinpoint where the ticking is coming from. Is it near the front of the engine, the rear, or somewhere in the middle? This can give you a clue about which components might be involved.

Check the spark plugs: If you’re comfortable working on your engine, you can check the spark plugs to make sure they’re properly installed and in good condition.

3. Preventive Measures

To keep your 5.7 HEMI ticking in good shape, it’s important to practice good maintenance habits.

Regular oil changes: Changing your oil regularly is crucial for maintaining oil pressure and keeping your engine running smoothly.

High-quality oil: Use high-quality oil as recommended by the manufacturer.

Timing chain inspection: Have your timing chain inspected regularly, especially if you’re nearing the recommended replacement interval.

4. Don’t Ignore the Tick

Even if the ticking seems minor, don’t ignore it. A small issue today can turn into a major problem down the road.

5. Don’t Assume It’s a Lifter Tick

While lifter tick is the most common culprit, don’t automatically assume it’s the culprit. A good mechanic can help you diagnose the specific cause and make sure the problem is addressed correctly.
