How Long Can You Drive With Bad Lifters?

How Long Can You Drive With Bad Lifters?

A lifter is connected to the crankshaft of your car, thus driving beyond 100 miles with a bad lifter can result in heavy damages that can be expensive for you to repair. If you’re driving a car with bad lifters, you might experience engine shudder or misfire during acceleration.

How Long Can You Drive With Bad Lifters? You can drive your vehicle max to 80 -100 miles with the bad lifters. However, please do not ignore the problem of bad lifters, and do not drive with it for more than 100 miles to prevent further car damages. 

Bad lifters can also cause the engine to backfire when it’s idling. If you notice any of these symptoms, it’s a good idea to have your car checked out as soon as possible because bad lifters can cause other problems to occur in the future if left unchecked.

What Are Lifters On A Car?

Lifters are often located in the upper cylinder heads and linked to the camshaft with a push rod so engine oil can move the lifter up or down. It is this movement that controls valves opening and closing during piston travel.

The average car weighs about 3,000 pounds or 1.5 tons. While that isn’t a lot compared to some of the larger and heavier vehicles on the market, it’s still a significant amount of weight. 

A motorist can use their vehicle for several years without adding any additional weight elsewhere in their car, but what happens before? That’s where lifters come into play. 

These units are typically installed to your trunk, back trunk lid, and rear bumper to help with the strain put on these areas during regular driving operations.

 Lifters are designed for several purposes and can prevent damage either now or in the future. Since a lifter is directly linked to an eccentric shaft in the camshaft, it works directly with engine timing, which means that a clogged lifter will not work at all. 

However, if you can hear some knocking sounds coming from your engine when driving your car, you are probably dealing with a clogged or dirty lifter. Thus you should check for the dirty lifters and should clean them from time to time for proper functioning.

How Hydraulic Lifters Work? 

A hydraulic lifting mechanism is a device that lifts objects using pressurized fluid under a pressure difference. This is done by using an eccentric rotating motion that causes a piston to slide back and forth in a cylinder with the help of an attached rod and belt. 

The rod can pull on the belt, which generates force at one end of the cylinder and pushes against an object or another component at the other end, thereby lifting it.

Hydraulic lifters use a liquid to create a cushion of air that can take up any lost space in your engine. For example, if your piston rod moves up and down while the cylinder walls stay still, it leaves a small amount of space at either end of the rod. 

If the engine has a too low ratio for that amount of movement, the piston can hit this space and damage your engine. 

The hydraulic lifters lift the rod high enough to completely move up and down, sometimes with more than 100% of its original weight. This high movement, combined with additional weight brought by the liquid, makes all moving parts run much smoother.

Hydraulic lifters are not the same as some high-end engines’ solid or mechanical lifters. These lifters are used in most cars, especially older models. 

They can be used with various engines and compression ratios to reduce engine noise. Sometimes they use a stiffening spring to keep the lifter still after it is pressed.

5 Symptoms Of A Bad Hydraulic Lifter.

Hydraulic lifters are a common component of modern cars. The lifters are often created with a steel cylinder, around which an oil reservoir is housed. When the fluid in the reservoir is pressurized, it forces the piston down, allowing smooth and efficient movement. 

Nowadays, hydraulic lifters may be found on vehicles from almost all manufacturers. The good news is that, in most cases, a hydraulic lifter will fail gradually.

 In some cases, it may fail suddenly, causing immediate difficulty in starting the car. A bad hydraulic lifter will have several symptoms. 

The five most common ones are:

  • Sticky Lifters 
  • Dead Cylinders    
  • Valve Issues 
  • Leaky Pipes 
  • Incomplete Shutdowns

It is important to note that a bad hydraulic lifter can indicate a larger issue. For example, if your vehicle is experiencing misfires and valve leaks, the problem might be linked to a dirty fuel injector or faulty oxygen sensor. 

If you experience any of these with your car, you should take it in for repair. A skilled technician should be able to identify these issues and repair them so that you can be back on the road. 

It’s also important to note that a bad lifter can cause problems with your valve train. A dirty lifter could cause a valve to get stuck in the open or closed position.

 A leaking lifter could allow oil to make its way into your cylinder and contaminate your sparkplugs, causing misfires. If you’re experiencing odd behavior with your engine or if it’s simply not performing the way it used to, then you should take it in for a proper diagnosis.

Engine Lifter Replacement Cost .

How Long Can You Drive With Bad Lifters?

If you notice your engine is not working as it should, it might be time to replace the engine lifters for your car. Engine lifts are relatively expensive and can cost up to 1000$ to 3000$ depending on the type of vehicle you have. 

The decision to repair or replace a defective component in a car is often an important one, which is why determining whether or not this repair is necessary takes consideration of three factors: parts costs, labor costs, and defect severity.  

Thus replacing engine lifters is a costly process and will depend upon many factors. But if you want to save some money, you can try to replace it if you know all the steps of fixing it. But it is advised to take your car to an excellent mechanic to change the lifters and avoid any other problems with your vehicle.
