How to Make the Hemi Tick Go Away When Warm

AvatarByCarl Frisch

Hemi tick is a common problem among vehicles equipped with Hemi engines. It occurs when the engine is cold and is often described as a tapping or rattling sound. The cause of the noise is usually due to the piston expansion caused by heat, which loosens the piston pin and causes it to move slightly in the bore of the cylinder. When the engine warms up, this movement decreases and the noise goes away. In some cases, additional repairs may be necessary to resolve this issue, such as replacing worn engine components or adjusting components that have become loose due to wear.

Automobile: Diagnosing an Engine ‘Hemi Tick’

The “Hemi tick” is a persistent problem that many Hemi engine owners experience and can be a source of frustration when trying to figure out the cause. The Hemi tick is a ticking noise that occurs in certain vehicle makes and models with Hemi engines. This noise can be heard when the engine is running and can range from a loud ticking to a quiet humming sound. In order to diagnose the issue, it is important to understand the causes, symptoms, and steps involved in diagnosing this issue.

Causes of Hemi Tick

The most common cause of the Hemi tick is worn or damaged valve lifters and pushrods which allow air to escape from the engine as it runs. This escaping air creates the ticking noise which can become increasingly louder over time. Other possible causes include an improperly adjusted valve lash clearance, a worn timing chain or tensioner, or clogged oil passages which prevent lubrication from reaching certain parts of the engine.

Symptoms of Hemi Tick

The most obvious symptom of a Hemi tick is the sound itself — whether it be a loud ticking or quiet humming sound — but there are other symptoms that may indicate an issue with your engine as well. These include reduced power output, decreased fuel economy, difficulty starting up your vehicle, or even excessive exhaust smoke due to incomplete combustion.

Steps to Diagnose a Hemi Tick

In order to diagnose the issue correctly and find out what is causing your Hemi tick, it’s important to follow these steps: First, make sure that all maintenance has been performed on your vehicle as recommended by your owner’s manual; this includes regular oil changes and other necessary services. If all maintenance has been done properly, then you should inspect all components of the valvetrain for any signs of wear or damage such as bent pushrods or worn valve lifters. You should also check for any clogged oil passages which could be preventing lubrication from reaching certain parts of your engine.

If you find any signs of damage or clogging during your inspection then you should replace those components before proceeding with further diagnosis. If no signs of damage are found then you may need to adjust the valve lash clearance according to your owner’s manual in order to eliminate any excess air escaping from the engine.

Once these steps have been taken and any necessary replacements made or adjustments done, you should start up your vehicle again and listen carefully for any signs of ticking noises coming from within the engine compartment.

If after following these steps you still hear a loud ticking noise coming from within your engine compartment then further diagnosis may be necessary in order to determine what is causing this noise.

Common Fixes for a Hemi Tick

Once you have identified what is causing your Hemi tick then you can take action in order to fix it. Common fixes include replacing worn valve lifters and pushrods, replacing timing chains and tensioners if necessary, or adjusting valve lash clearance if needed. All of these fixes should help reduce or eliminate any ticking noises coming from within your engine compartment.

How To Prevent A Hemi Tick From Occurring

There are some things that owners can do in order to prevent their vehicles from experiencing a Hemi tick in the first place. Regular maintenance such as regular oil changes are essential in keeping all components properly lubricated which will help reduce wear over time. Additionally, avoiding overheating your vehicle by making sure that all cooling system components are functioning properly will help reduce strain on internal components which could lead to premature wear.

What Type Of Automobile Is Most Prone To Having A Hemi Tick?

Different automobile makes/models with Hemi engines can experience this issue depending on their design; however some models seem more prone than others due to common issues experienced with those particular vehicles such as faulty PCM calibration settings which can cause improper valve lash adjustment leading to increased air escape into the exhaust system creating an excessive ticking sound.

What Are The Advantages Of Having A Hemi Engine? One key advantage of having a hemi-engine equipped car is its increased horsepower and torque outputs compared with standard engines; this allows for faster acceleration times while still providing good fuel economy figures due its efficient combustion process which also reduces emissions compared with standard engines.< br >< br >Finally , one thing worth noting about hemi-engines is that they tend not go away when warm , so if you’re hearing persistent ticking noises even after following all these steps , chances are it’s not going anywhere anytime soon!

Increased Cost of Parts and Maintenance

The cost of parts for a Hemi engine is generally higher than for a regular engine, due to the complexity of the design. This can lead to higher expenses in general when it comes to maintenance and repairs. In addition, some mechanics may not be as familiar with the Hemi engine and thus may charge more for their labor as they learn more about it.

Beyond the cost of parts, there is also the cost of fuel to consider. The Hemi engine’s larger displacement means that it uses more fuel than a regular engine, and this increased fuel consumption will add up over time.

Heavy Weight Due to Cast Iron Blocks

Hemi engines tend to be heavier than other types of engines due to their use of cast iron blocks. This added weight can reduce handling performance and increase fuel consumption, as well as necessitating heavier suspension components in order to cope with the extra strain from the added weight. This can be an issue if you plan on using your vehicle for off-roading or other activities that require lighter vehicles.

Hemi Tick Goes Away When Warm

Some Hemi engines have been known to produce a ticking sound when cold, which is caused by block expansion due to heat build-up within the cylinders. Fortunately, this ticking noise usually goes away once the engine warms up and its components expand enough that they no longer rub against one another. However, if this noise persists even after your engine has warmed up, then you should have it checked out by a certified mechanic as soon as possible in order to diagnose and fix any potential problems before they become worse.
