How to Prevent HEMI Lifter Failure: The Ultimate Guide
In a HEMI engine, lifter failure can occur for several reasons. However, some preventative measures can be taken to reduce the likelihood of it happening.
One of the most important things to do is keep the engine clean and debris-free. This means regular oil changes and using the proper type of oil filter.
Additionally, avoiding overloading the engine and putting too much strain on the lifters is essential. If you notice any unusual noise or vibration from the engine, have it checked out by a professional as soon as possible.
With that set-aside, let’s dive a little deeper into this topic so, at the end of this blog, you will come out more knowledgeable about this lifter thang.
1. What is a HEMI lifter, and what does it do in the engine?
A HEMI lifter is a device that helps to raise and lower the pistons in an internal combustion engine. The piston sits atop the cylinder and moves up and down as the crankshaft turns. The HEMI lifter assists in this movement by providing a smooth, consistent surface for the piston to travel on.
HEMI lifters are essential for proper engine operation. Without them, the pistons would not be able to move smoothly and could become damaged or even break. Additionally, HEMI lifters help to keep the engine clean by preventing oil and other debris from entering the cylinders.
2. The consequences a HEMI lifter failure
If a HEMI lifter fails, the piston may become damaged or break. Oil and other debris may also enter the cylinder, causing the engine to become dirty and potentially damaging other engine parts. In severe cases, a HEMI lifter failure can cause the engine to seize, resulting in expensive repairs or even replacement.
It is vital to regularly check your HEMI lifters for wear and tear to avoid these consequences. If you notice any damage, have the lifters replaced as soon as possible to prevent further damage to your engine.
3. Common causes of HEMI lifter failure
One of the most common causes of HEMI lifter failure is a lack of lubrication. The lifters can become dry and damaged when the engine is not adequately lubricated. This can cause them to fail prematurely.
Another common cause of HEMI lifter failure is due to excessive heat. The lifters can become warped and damaged if the engine runs too hot. This can also cause them to fail prematurely.
Yet another common cause of HEMI lifter failure is due to contamination. The lifters can become clogged and damaged if the engine becomes contaminated with dirt or debris. This can also cause them to fail prematurely.
4. How to troubleshoot a HEMI lifter problem, common symptoms?
If you own a 5.7 HEMI engine, you may be familiar with the lifter failure symptoms. These engines are known for their high performance and durability, but they can also be susceptible to lifter failure.
Common symptoms of a HEMI lifter problem include:
- Engine noise that is louder than usual
- A knocking or tapping noise coming from the engine
- A loss of power or performance
- Engine vibration
- Rough idling
If experiencing any of these symptoms, you must take your vehicle to a qualified mechanic for diagnosis and repair. Trying to fix a HEMI lifter problem yourself can be dangerous and worsen the situation. Fix up that HEMI engine tick with this ultimate guide.
5. How much will it cost to have a HEMI lifter failure repaired or replaced in your car engine, and how long will the repair take?
The cost of repairing or replacing a HEMI lifter will vary depending on the damage’s extent and the engine type in your vehicle. In most cases, the repairs will be expensive and may take several hours to complete. If the problem is severe, you may need to have the engine replaced entirely. This can be a very costly repair, so it is important to take steps to prevent HEMI lifter failure in the first place.
6. What happens if you drive with bad lifters?
If you ignore the symptoms of bad lifters and continue driving your vehicle, the lifter issues will intensify and cause damage to other system components. The ticking noise will become louder and more pronounced; eventually, the engine will develop a miss on the cylinder with the failed lifter. This can lead to extensive engine damage and potentially costly repairs if left unchecked.
7. Recommended maintenance for preventing HEMI lifter problems
HEMI lifters are an essential component of your engine, and keeping them in good working order is important. There are a few things you can do to help prevent HEMI lifter failure:
- Make sure to regularly check the oil level in your engine and top it off as needed. Oil is essential for lubricating the moving parts in your engine, and HEMI lifters are no exception.
- Have your engine’s oil changed regularly. Over time, oil can break down and become less effective at lubricating and protecting your engine components.
- Avoid running your engine at high speeds for extended periods. HEMI lifters operate within a specific speed range, and running them outside this range can cause wear and tear.

- Don’t use lower-quality or off-brand oil in your engine. Using the wrong type of oil can cause it to break down more quickly, leading to reduced protection for your engine components.
- Avoiding extended periods of idling. When your engine is idling, the oil isn’t circulated as much and can start to break down.
Following these simple tips can help prevent HEMI lifter failure and keep your engine running smoothly.
Over to you
HEMI lifter is an integral part of your engine, and keeping them in healthy working order is crucial. There are a few things you can do to help prevent HEMI lifter failure:
- Make sure to regularly check the oil level in your engine and top it off as needed.
- Have your engine’s oil changed regularly.
- Avoid running your engine at high speeds for extended periods.
- Don’t use lower-quality or off-brand oil in your engine.
- Try not to let it idle for a long period.
