What is the Hemi Tick?
The Hemi engine is a popular V8 engine design used in many American muscle cars. It is known for its power and performance, but there is one issue that many Hemi engine owners have experienced, and that is the Hemi tick. The Hemi tick is a ticking sound that emanates from the engine, which can be quite annoying and worrisome to the vehicle owner. The noise is usually noticeable at low idle and can be more pronounced when the engine is cold. The sound is not usually a sign of any serious problem with the engine but can be a bit of a nuisance. In this article, we will explore how to fix the Hemi tick and get your engine purring once again.
The Hemi tick is caused by the valve lifters in the engine. These lifters help to move the valves up and down, allowing air and fuel to enter the engine and exhaust gases to exit it. Over time, these lifters can become worn, leading to a ticking sound as they move up and down. Another cause of the Hemi tick is a lack of oil pressure in the engine. If the engine oil is not flowing properly, the lifters can become dry and start to make noise.
If you are experiencing the Hemi tick in your engine, there are a few things you can do to fix it. The first step is to perform an oil change, ensuring that you use the right type of oil recommended for your Hemi engine. This will help to increase the oil pressure, reducing the dryness of the lifters and reducing the noise. The engine oil should be changed every 3,000 to 5,000 miles, depending on the make and model of your car.
If an oil change doesn’t resolve the Hemi tick, the next step is to replace the lifters in the engine. This can be done by removing the valve covers and removing the old lifters. New lifters can then be installed, and the valve covers replaced. This is a more involved process than an oil change and should be done by a trained mechanic or experienced DIYer. It is essential to buy high-quality lifters that are compatible with your Hemi engine model, as using poor quality parts can cause additional problems and ultimately damage your engine.
If you have done an oil change and replaced the lifters in your engine, and the Hemi tick persists, it may be an indication of a more serious engine problem. In this case, we recommend getting your engine checked by a trained mechanic as soon as possible to ensure that the problem doesn’t worsen and lead to more significant engine damage.
The Hemi tick may be a common problem for Hemi engine owners, but it is not something to be overly concerned about. With a few simple steps, you can fix the problem and get back to enjoying the power and performance of your Hemi engine. Remember to change the oil on time and keep your engine in good condition, and the Hemi tick will be one less thing to worry about.
Tools Needed for Hemi Tick Fix
Fixing the Hemi tick requires some basic tools that you may already have in your garage. Here are the tools you will need:
1. Socket Wrench Set
You will need a socket wrench set to remove the valve covers, which will give you access to the lifters. A socket wrench set consists of several different sized sockets and a ratcheting handle. It is important to have a set with a range of socket sizes to ensure that you have the right size for each bolt you need to remove.
2. Feeler Gauge Set
A feeler gauge set is used to measure the gap between the rocker arm and the lifter. The Hemi tick is caused by excessive gap between these two components. The feeler gauge set is a collection of metal strips of different thicknesses, which allows you to measure the gap between the rocker arm and lifter accurately. It is important to find the correct thickness gauge that matches with your vehicle’s specifications to achieve optimal results.
3. Torque Wrench
A torque wrench is necessary to torque the bolts to the proper specification when reassembling the engine parts. Over-tightening can lead to damage to both the bolt and the components it is securing. Conversely, under-tightening can cause the bolt to loosen over time. It is imperative to torque the bolts to the recommended torque specification for your vehicle model.
4. Ratchet and Allen Wrench Set
While not strictly necessary for fixing the Hemi tick, a ratchet and Allen wrench set will come in handy if you need to remove any other components that use hexagonal bolts instead of regular bolts. This includes components such as the intake manifold or valve covers. An Allen wrench is a L-shaped or T-shaped tool used to turn hexagonal bolts or screws with a hexagonal socket on one end, and a ratchet is used to turn other types of bolts or screws.
5. Shop Towels and Cleaner
It is essential to have shop towels and a cleaner handy while fixing the Hemi tick. The engine oil can be messy, and components can be oily and greasy after a prolonged period of use. You must clean the parts to ensure that no debris or dirt is left behind.”
Now that you know what tools you need, it’s time to jump into the steps to fix the Hemi tick and get your engine back to running smoothly!
Steps to Fixing the Hemi Tick
If you’re hearing a ticking sound coming from your Hemi engine, don’t worry – you’re not alone. The Hemi tick is a common problem that affects Dodge and Jeep vehicles with Hemi engines. Fortunately, it’s usually not a serious issue and can often be easily fixed. Here are the steps you can take to fix the Hemi tick:
1. Check Your Oil Level
The first step in fixing the Hemi tick is to check your oil level. Low oil pressure can cause the lifters in your engine to tick, so it’s important to make sure your engine has enough oil. Start by checking your oil level with the dipstick and adding more oil if necessary. If your oil level is low, it’s also a good idea to inspect your oil filter and replace it if it’s dirty.
2. Use the Right Oil
Using the right oil is important when it comes to fixing the Hemi tick. Hemi engines require a specific type of oil to function properly, so make sure you’re using the right kind.

3. Replace Your Lifters
If your oil level is good and you’re using the right oil, but you’re still hearing the Hemi tick, you may need to replace your lifters. Lifters are small components in your engine that help regulate the flow of oil. When lifters become worn or damaged, they can cause a ticking noise. To fix the Hemi tick caused by worn lifters, the lifters will need to be replaced.
To replace your lifters, you’ll need to remove the cylinder head from your engine. This is a complex job that requires advanced mechanical skills, so it’s usually best to leave it to a professional mechanic. The mechanic will remove the old lifters and replace them with new ones, ensuring they’re properly lubricated and adjusted.
Once the lifters have been replaced, the ticking sound should disappear. However, it’s important to note that if the Hemi tick is caused by a more serious issue, such as a damaged camshaft or rocker arm, replacing the lifters may not fix the problem. If you’re not confident in your ability to diagnose and fix the Hemi tick yourself, it’s always best to take your vehicle to a trusted mechanic for help.
Overall, the Hemi tick is a common issue that can usually be fixed with a few simple steps.

Common Mistakes to Avoid
If your Dodge engine is emitting a ticking sound, it could be a result of the Hemi technology design which reduces cylinder head size to achieve greater combustion efficiency. However, it also reduces the space for valve train components. The ticking sound occurs when the rocker arm either sticks or slides erratically. In addition to the sound, other factors that indicate a ticking engine include a reduction in horsepower and engine performance.
Here, we will discuss the common mistakes people make while attempting to fix the Hemi tick:
1. Frequent Oil Changes
Frequent oil changes may help in reducing the ticking sounds; however, the problem persists. Over time, oil accumulates inside the engine, creating a gummy substance that clogs the engine blockages, leading to engine ticking. Due to the gummy nature of the substance, it is challenging to remove with lubricants easily. Therefore, frequent oil changes do not resolve the Hemi tick problem.
2. Using the Wrong Oil
The Hemi tick requires the engine oil to be thicker, with a strong viscosity rating of 5W-20 or 5W-30. Using the wrong engine oil could lead to camshaft wear and other valve train components. Rather than rely on the car’s manual for specifics on the engine oil for your Dodge, ensure that the oil has Hemi tick specifications or consult with an expert.
3. Installing the Wrong Lifter or Headbolts
If you are diagnosing and resolving the Hemi tick problem by replacing lifters or head bolts, ensure that the components you use meet manufacturer’s specifications, or they will fail again. If the head bolts or lifters are the wrong size or length, it could lead to damage to other engine components, resulting in a costly engine overhaul. Lifter and head bolt substitutions for the 5.7L Hemi engine are widespread, so it is crucial to ensure that you have accurate specifications.
4. There is no Magic Additive or Gimmick that will fix the Hemi Tick
There is no magic additive or gimmick that will fix the Hemi tick permanently. Ticking sounds may persist even after using oil additives and metal treatments. Although some additives alleviate the problem by improving the lubrication, they cannot eliminate it altogether. Additionally, some dealerships may charge excessively for services promising to fix the ticking sound using oil additives or fluid flushes. However, they may not guarantee a permanent fix. Therefore, exercising caution and consulting with a specialist before partaking in any quick-fix hypes would be helpful to avoid wasting both time and money while fixing the Hemi tick.
