How to Prevent Hemi Lifter Failure

Hemi lifters are a type of hydraulic lifter that uses oil pressure to adjust the clearance between the pushrod and rocker arm. Hemi lifters can fail due to a number of reasons, including wear and tear, improper installation, and lack of lubrication.

Preventing hemi lifter failure involves regular maintenance and careful driving practices. The lifter is an essential component in the engine’s valve train system, and if it fails, it can lead to serious engine damage.

Here are some tips to help prevent hemi lifter failure:

  1. Regular oil changes: Ensure that you follow the manufacturer’s recommended oil change intervals and use the right type of oil. Clean and sufficient oil is crucial for the proper lubrication of engine components, including lifters.
  2. Use high-quality oil and additives: Choose high-quality engine oil with the appropriate viscosity for your vehicle. Some drivers also use additives that can help clean and protect the lifters.
  3. Avoid aggressive driving: Aggressive driving, such as excessive speeding, rapid acceleration, and abrupt braking, can put additional stress on engine components, including lifters. Drive smoothly and avoid over-revving the engine.
  4. Warm up the engine: Letting your engine warm up before driving can help ensure that oil is evenly distributed and reaches all the necessary components, including lifters, providing proper lubrication.
  5. Regular maintenance: Follow the manufacturer’s recommended maintenance schedule, and have a professional mechanic inspect your engine regularly. They can identify potential issues before they escalate into major problems.
  6. Keep the engine clean: A clean engine is less likely to experience lifter problems. Avoid driving in dusty or sandy environments, and periodically check and clean the engine bay.
  7. Address engine issues promptly: If you notice any unusual noises, such as ticking or knocking sounds coming from the engine, have it inspected immediately. Ignoring such noises can lead to more severe problems with the lifters and other engine components.
  8. Avoid prolonged idling: Extended periods of idling can cause inadequate lubrication and overheating of engine components. If you need to park for an extended period, consider turning off the engine.
  9. Install a quality oil filter: A good quality oil filter can help remove contaminants and debris from the oil, ensuring cleaner oil reaches the lifters and other engine components.
  10. Be mindful of the engine’s RPM range: Avoid constantly operating the engine at high RPMs for extended periods, especially when it is not necessary. High RPMs can put more stress on the lifter and other engine parts.

Remember that prevention is always better than cure when it comes to engine problems. By following these tips and maintaining your vehicle properly, you can reduce the risk of hemi lifter failure and enjoy a smoother, more reliable driving experience.

5.7 Hemi Lifter Replacement Without Removing Head

If your 5.7 Hemi engine is making noise, it could be due to a problem with the lifters. The good news is that you can replace the lifters without removing the head from the engine.

This process is relatively simple and can be done in a few hours.

To start, you’ll need to remove the valve covers from the engine. Once they are off, you can access the lifters. There are two bolts holding each lifter in place. Remove these bolts and then pull out the old lifter.

Now, take your new lifter and place it in the opening where the old one was removed. Start by threading in one of the bolts and then tighten it down with a wrench.

Repeat this process for the other bolt and then move on to the next lifter until all of them have been replaced.

Once all of the new lifters are in place, you can reinstall the valve covers and start up your engine. It should now be running smoothly without any noise coming from the lifters!

What Causes Lifter Failure in 5.7 Hemi?

Lifter failure in a 5.7 Hemi engine can be caused by a few different things.

The most common cause is simply wear and tear on the lifters themselves. Over time, the metal components of the lifters can break down and wear out, causing them to fail.

Another potential cause of lifter failure is an issue with the oil pressure in the engine. If the oil pressure is too low, it can cause the lifters to not function properly and eventually fail.

Lastly, if there is any debris or contamination in the engine oil, it can also cause the lifters to fail.

How Do You Prevent Hemi Ticks?

There are a few things you can do to help prevent Hemi ticks. First, make sure your dog is on a tick preventive medication. There are many different brands and types of tick preventives, so talk to your veterinarian to find the best one for your dog.

Second, keep your dog away from areas where ticks are commonly found, such as woods and tall grass. Finally, check your dog for ticks regularly, especially after he or she has been in an area where ticks may be present. If you find a tick on your dog, remove it immediately with tweezers or a tick removal tool.

Do the New Hemis Have Lifter Problems?

The new Hemi engines have had some lifter problems. The main problem has been with the hydraulic roller lifters. Some of the lifters have failed and caused engine damage.

The other problem has been with the valve lash adjusters. These have also failed and caused engine damage.

How Much Does It Cost to Replace a Lifter on a 5.7 Hemi?

If you’re the do-it-yourself type, you can expect to pay anywhere from $200 to $400 for a new lifter. The cost of labor will depend on your mechanic, but it’s generally between $100 and $200 per hour. So, all told, you’re looking at a bill of between $300 and $600 to replace a lifter on a 5.7 Hemi.

Of course, this is just a ballpark figure – the actual cost could be higher or lower depending on the specific circumstances of your car and your chosen mechanic.


If you own a Hemi engine, you know that lifter failure is a common issue. But what causes lifter failure and how can you prevent it? Lifter failure is usually caused by one of two things: either the lifters are not properly lubricated or they are wearing out.

If your lifters are not properly lubricated, they will eventually wear out and fail. To prevent this, make sure to regularly oil your engine and check the level of oil in your crankcase. If your lifters are already starting to wear out, there are still some things you can do to prevent complete failure.
