When it comes to maintaining your vehicle, sometimes small issues can turn into major problems if left unchecked. One such issue is a faulty lifter, also known as a hydraulic tappet or cam follower. These components play a crucial role in the operation of your engine by opening and closing the valves in sync with the movement of the camshaft. If a lifter fails or becomes damaged, it can cause a variety of issues including reduced engine performance, abnormal noises, and even engine failure. In some cases, it may be necessary to replace just one lifter rather than the entire set. This can be a cost-effective solution, but it’s important to consider the potential consequences and whether or not it is the best course of action for your specific situation. In this article, we will discuss the factors to consider when deciding whether to replace just one lifter or the entire set, as well as the steps involved in the replacement process.
Can you replace just one lifter?
Yes, it is possible to replace just one lifter in a vehicle’s engine. However, there are a few factors to consider before making this decision.
What are the factors to consider when deciding whether to replace just one lifter or the entire set?
There are a few key factors to consider when deciding whether to replace just one lifter or the entire set:
- Cost: Replacing just one lifter may be a more cost-effective solution compared to replacing the entire set. However, it’s important to keep in mind that if you only replace one lifter, you may have to replace it again in the future if the other lifters begin to fail.
- Age of the engine: If the engine is relatively new and in good condition, replacing just one lifter may be a viable option. However, if the engine is older or has been subjected to heavy use, it may be more cost-effective in the long run to replace the entire set of lifters to ensure that the engine continues to operate smoothly.
- The extent of the damage: If the damage to the faulty lifter is extensive, it may be best to replace the entire set to ensure that the other lifters are not also close to failure.
- Type of engine: Some engines, such as those with overhead camshafts, may be more prone to lifter failure. In these cases, it may be more advisable to replace the entire set of lifters to prevent future issues.
The steps involved in replacing a lifter depend on the specific engine and vehicle, but generally include the following:
Drain the engine oil and remove the oil pan.
- Remove the valve cover and locate the faulty lifter.
- Remove the pushrods and rocker arms associated with the faulty lifter.
- Remove the faulty lifter and install the new one in its place.
- Reinstall the pushrods and rocker arms and replace the valve cover.
- Refill the engine with oil and replace the oil pan.
- Start the engine and check for any leaks or abnormal noises.
It’s important to note that replacing a lifter can be a complex and labor-intensive process, so it may be best to have a professional mechanic handle the job if you are not comfortable or experienced in working on engines.
Is it hard to replace a lifter?
The replacement of one or more lifters is an expensive and time-consuming procedure. You should typically budget between $1,000 and $2,500 if you decide to hire a professional to complete the task. The precise price will, of course, vary depending on a number of variables, including the year, make, and model of your car.

Can low oil cause lifter noise?
Hydraulic valve lifters may become slightly oil-starved. These lifters employ oil to modify clearance so that the valve’s tap, tap, tap sound is imperceptible. The noise will result from low oil. Additionally low oil pressure from an old engine.
Does lifter tick increase with RPM?
Lifter tick, which is a type of engine noise that is often caused by a faulty lifter, can sometimes increase with rpm (revolutions per minute). This is because as the engine’s rpm increases, the lifters are subjected to more stress and wear, which can exacerbate any existing issues.
However, it’s important to note that the relationship between lifter tick and rpm is not always straightforward. In some cases, the lifter tick may be more pronounced at lower rpms, while in other cases it may be more noticeable at higher rpms. Additionally, the severity of the lifter tick can vary depending on factors such as the condition of the lifters and the overall health of the engine.
If you are experiencing a lifter tick, it’s important to have the issue addressed as soon as possible. In some cases, replacing just one faulty lifter may be sufficient to fix the problem. However, if the lifters are severely worn or the engine is in poor condition, it may be necessary to replace the entire set of lifters or perform more extensive repairs.
Do you have to replace cam when you replace lifters?
It is not always necessary to replace the camshaft when you replace the lifters in a vehicle’s engine. In most cases, the camshaft can be reused as long as it is in good condition.
However, if the camshaft is also damaged or worn, it may be necessary to replace it along with the lifters. This is because the camshaft and lifters work closely together and if the camshaft is not in good condition, it can cause problems with the operation of the lifters.
It’s important to note that replacing the camshaft and/or lifters can be a complex and labor-intensive process, so it is usually best to have a professional mechanic handle the job if you are not comfortable or experienced in working on engines.
