What Causes 5.7 Hemi Lifter Failure?

There are several potential causes of lifter failure in a 5.7 Hemi engine. Some of the most common include:

1. Lack of Proper Maintenance

The most reported cause of the lifter failure in a 5.7 Hemi engine is a lack of proper maintenance. Many users don’t change the engine oil regularly, and there are many who use low-quality oil. In both cases, it may build up contaminants which can damage the lifters.

2. Overheating of the Engine

Overheating is another major threat for engines including the 5.7 Hemi engine. Sometimes the radiator or the thermostat doesn’t function properly. In that case, it overheats the engine which may be the reason behind lifter failure as well as other issues like warped cylinder heads.

3. Worn or Damaged Components

The camshaft and pushrods in a 5.7 Hemi engine can become worn over time or may be damaged due to other issues. This can also lead to lifter failure. So, you should check the camshaft and pushrods regularly and replace those when they are damaged.
