The 5.7 Hemi engine is a powerful and reliable choice for many vehicles. However, like any other engine, it may have issues that can affect its performance. One such common problem is lifter failure, which can have a range of symptoms and can be caused by several factors. Before you start fixing the issue, you should know which factor caused the problem. In this article, we’ll discuss the symptoms of 5.7 Hemi lifter failure, the causes behind it, and what you can do to fix it.
How do I know if my 5.7 Hemi has lifter failure?
As we discussed earlier on, there are several symptoms that may indicate lifter failure in a 5.7 Hemi engine. These are:
- Knocking or ticking noises coming from the engine
- Reduced engine power or performance
- Increased engine oil consumption
- Excessive exhaust smoke
- Can I drive my vehicle with a failed lifter?
It is generally not recommended to drive a vehicle with a failed lifter, as it can cause further damage to the engine. So, if you are experiencing any of the symptoms listed above, you should consider having your vehicle checked by a mechanic as soon as possible.
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.
