What Are Lifters?
Hydraulic lifters, also known as hydraulic lash adjusters, solid lifters, and hydraulic tappets, are vital components of an internal combustion engine (ICE). They are responsible for allowing the rocker arms and valves to remain in contact even when subjected to extreme heat. Without them, the parts could bind against each other causing vibrations or rattling noises to occur. This can cause accelerated wear on the engine and decrease its overall lifespan.
Hydraulic lifters are designed to automatically adjust the valve clearance to ensure a minimal tolerance between the two parts is maintained. This ensures that there is no binding occurring from thermal expansion due to engine heat. The result is quieter operation, longer engine life, and less need for scheduled valve adjustments.
Manufacturers design hydraulic lifters using components such as a push rod, plunger, and adjusting nut. A push rod connects it to the camshaft while a plunger is pushed into contact with the rocker’s arm by spring pressure when cold but retracts when hot due to its special construction materials that expand when heated up. An adjustable nut maintains a set pre-load on the plunger which shifts it back into contact with the rocker’s arm once cooled down again.
How Do Hydraulic Lifters Work?
Hydraulic lifters are an essential component of any vehicle’s engine and have a crucial job: they effectively reduce the amount of noise generated by the engine when running. In a hydraulic lifter, the valve is connected to a small rod known as the rocker’s arm. Inside the hydraulic lifter is a combination of oil, plunger, and spring that creates clearance within the valve train, producing quieter driving conditions. The oil also helps to lubricate parts of the engine and reduces wear and tear, thereby reducing maintenance costs and extending its life.
However, if there is not enough oil pressure in the hydraulic lifter, it can affect its performance. This may result in unusual noises coming from the engine or even worse damage to other components such as the tip of the valve, rocker’s arm, or push rod – all costly repairs that need addressing quickly. To prevent this from happening, it is important to regularly check your vehicle’s fluids and ensure that there is an adequate level of oil pressure in your engine’s hydraulics system.
Hydraulic Lifter Location
The location of hydraulic lifters can vary depending on the vehicle’s make and model, but they are usually found at the top or bottom of your engine. If you have a push rod and rocker arm setup, then the hydraulic lifter might be located somewhere in between. It is important to note that regardless of what type of car you have, there will always be some form of mechanical lifter in place. Without a hydraulic lifter, the camshaft would be unable to move the valves correctly. As such, they are essential components in any engine and should be regularly inspected and maintained for optimal performance.
Bad Hydraulic Lifter Symptoms?
There are a few tell-tale signs that indicate when your hydraulic lifters may be malfunctioning. These include:
Sticky Lifters
A sticky lifter keeps itself in a contracted position instead of expanding and contracting. When the system cannot sustain oil pressure due to the immovable parts, it leads to internal hammering that produces more noise. Such damage can be avoided by ensuring regular maintenance is done on your vehicle’s lifters.
Noisy Lifters
Excessive noise that occurs during engine startup or idle is an indication of faulty lifters. This suggests a lack of oil pressure in the lifter, which can lead to other parts being damaged due to excessive wear and tear.
Inaccurate Valves
If your vehicle’s valves are not opening and closing properly, it is likely that the hydraulic lifter is not working correctly. This can cause your engine to run roughly or misfire as airflow cannot move in and out of the cylinders correctly.
More RPM Causes More Noise
If your engine is making more noise when the revs are higher, this could be an indication of a faulty lifter. Badly worn hydraulic lifters can produce more noise as the engine speed increases due to increased oil pressure and metal-to-metal contact.
Oil Leaks
Hydraulic lifters that are not operating correctly can cause oil leaks. This is due to the seals in the lifters becoming worn and allowing oil to escape. Regularly checking your vehicle for signs of oil leakage can help identify any potential problems with the hydraulic lifter system before they become more serious.
Misfires
Misfiring engines are a common sign of faulty hydraulic lifters. This can be caused by the lifters being unable to hold their adjustment or if they become stuck in a retracted position, which will lead to inaccurate valve timing.
Broken Pushrods and Dead Cylinders
Dead cylinders are a common problem and can decrease engine performance significantly. The main cause of dead cylinders is bad lifters, which can bend or break the pushrods they interact with. Pushrods are cylindrical metal tubes that are used to transfer motion from the cams on the lifters to the valves in the engine. When the lash adjuster is faulty or broken, the pushrods will also suffer and cause the corresponding cylinder to cease functioning.
Check Engine Light
Finally, your vehicle’s check engine light may come on if it is having trouble with the hydraulic lifters. If this happens, it is important to take your vehicle to a certified mechanic as soon as possible so that the underlying cause can be identified and any necessary repairs can be made.
If you notice any of the above symptoms in your vehicle, you should have it checked as soon as possible to ensure the problem does not become worse. A professional mechanic can help you diagnose the issue and provide a suitable solution so that your vehicle runs smoothly and efficiently.
What causes the hydraulic lifter to go bad?
Although automobile lifters are designed to last, sometimes they inevitably fail and require replacement. To understand why this happens, it is essential to be aware of the most common causes that lead to a malfunctioning lifter:
Engine oil and oil condition
The primary cause of a hydraulic lifter going bad is insufficient or incorrect oil levels in the crankcase, as this can cause a lack of lubrication or result in bubbles or aeration in the oil. If the engine oil is too thin, contaminated, or in poor condition, it can affect the functioning of the lifter. Low-grade oil will reduce its ability to lubricate and slow down the movement of parts. Contamination with sludge and debris can clog up important components and lead to a malfunctioning lifter.
In order to ensure that your hydraulic lifters remain in good condition, it is important to check the oil levels and quality regularly, ensuring that they are at the correct level and free from contamination. If you suspect any damage or decreased performance due to a faulty hydraulic lifter, it is recommended that you seek professional assistance as soon as possible.
Wrong viscosity rating
Oil viscosity is a critical factor for keeping an engine in good condition and performing optimally. Heavy-viscosity oils, such as 40W and 20W-50, do provide elevated oil pressure in warmer climates, but this can be inadequate for cold weather conditions, particularly during initial startup. This issue can be particularly noticeable with overhead cam engines, where the oil must travel farther vertically. On the other hand, light-viscosity oils, such as 5W-20 or straight 10W, are better suited for cold weather but can be too thin and not supply enough lubrication in hot temperatures. Therefore, most engine manufacturers recommend 5W-30 as a reliable all-season oil.
Lousy oil filters and screens
If you haven’t changed your oil filter in an extensive period of time, the resulting clog and restricted oil flow can cause a plethora of engine issues. As if that weren’t enough, a low-quality or aged filter may be to blame for triggering the blinking or steady warning light on your vehicle’s instrument cluster. In order to ensure that your hydraulic lifter operates properly, make sure that you check and change your oil filters and screens regularly.
Incorrect assembly
If the lifter has not been correctly assembled, it may not be able to function properly. This can cause the lifter to make sounds or become faulty, leading to a performance decrease and eventually failure. It is essential that you follow the instructions when assembling your hydraulic lifters in order for them to operate effectively and without incident.
Lash Adjustment
Hydraulic lifters are an important part of any engine and require careful adjustment. In order for the lifter to work properly, it must be set to ‘zero lashes’, which means that any pressure exerted by the cam or push rod is cushioned by oil inside its casing. If this adjustment is off, it can cause excessive wear on the cam and lifter, as well as bent push rods.
To prevent this, it’s recommended that solid lifters be adjusted every 30,000 miles or so. If this adjustment is not done in a timely manner, serious damage to the engine can occur. Therefore, it is important to ensure that your lifter adjustment is done correctly and regularly.
Old engine and lack of maintenance
As engines age, components start to wear down and could even become corroded or damaged. If the engine has not been well maintained, chances are that hydraulic lifters can malfunction due to worn-out parts and inadequate lubrication. Regular maintenance will ensure that all components remain in good condition and your engine is running optimally.
Wear and tear
Over time, hydraulic lifters can suffer from gradual wear and tear due to prolonged use. This can be caused by either a small crack or leak in the chamber that houses the oil, allowing air to enter and causing pressure issues. It can also be down to dirt and debris entering the system, which can prevent its proper functioning.
These are just some of the reasons that can cause a hydraulic lifter to go bad. In order to ensure that your engine is running smoothly and efficiently, it is important to check the condition of your hydraulic lifters regularly. If you suspect any damage or decreased performance, seek professional assistance as soon as possible in order to avoid further issues.
Engine Lifter Replacement Cost
Replacing an engine lifter can be a daunting task due to the various factors that come into play. While it’s possible to replace just one single lifter, it’s generally recommended to replace all of them in order to avoid future problems. The cost of a single lifter will range from $5-$30; but when replacing multiple lifters, the price can increase significantly depending on the type of engine and the number of valves present. It may be necessary to buy gaskets, bolts, and other components at a premium cost as well.
Labor costs for such replacement jobs can also be steep. Depending on the type of engine involved, it could take anywhere between 3-10 hours to complete the job – with labor rates typically ranging from $100/hr. This means that even if you manage to get cheap parts, you could still end up paying a hefty amount in labor charges alone. For instance, if you were replacing 16 lifters in an average V8 engine, it could cost around $1000-2000 in total (including parts and labor).
A more economical option would be buying refurbished lifters instead of new ones; however, this usually doesn’t make much difference for labor costs so it isn’t recommended unless there is no other choice available. Moreover, these parts may not perform as effectively as brand-new ones leading to potential problems down the line.
In conclusion, replacing engine lifters can be quite expensive due to both part and labor costs involved; however, it’s important for the performance and longevity of your vehicle so shouldn’t be neglected under any circumstances. Make sure you always work with experienced mechanics who use high-quality parts in order to keep your car running perfectly for years to come.
How Do You Fix A Bad Lifter?

Understanding each step is essential for the proper maintenance of your vehicle’s hydraulic lifters.
Materials Needed
Before beginning the cleaning process, you will need to have certain items on hand. These include your preferred engine flush cleaner, jack stands, an oil drain pan, an oil filter, a replacement oil drain plug (in case the old one is damaged), and new oil following your car’s specifications. Be sure to research what exactly your specific vehicle requires as well as follow any instructions given by both manufacturers of engine cleaners and vehicle manufacturers.
Step 1: Adding Engine Flush Cleaner
The first step in this process is adding your chosen engine flush into the engine of your car. Open up the oil cap and add in a suitable amount based on how big your engine is. Make sure that you adhere to all directions found on the label of the engine flush product; if your engine is large enough it may require two or more bottles of cleaner instead of just one. When you’re finished with this part, make sure that you securely close off the cap once again before continuing on to Step 2.
Step 2: Running The Engine
After pouring in some of the engine flush detergents, it will be time to start up your car and let it idle for roughly 15 minutes worth of time. This allows for optimal results as far as getting rid of any dirt and grime build-up inside out. You may hear a decrease in noise coming from within your lifters due to them being slowly but surely cleaning out during this period; when that 15 minutes have elapsed then go ahead and turn off your car again afterward.
Step 3: Drain The Oil & Remove the Oil Filter
Placing an oil drain pan underneath your car’s oil drain spout, you will then be able to go ahead and empty out the existing oil from within. Once that’s done, unscrew the oil filter and set it aside so that you can replace it with another one later on.
Step 4: Replacing Oil Filter & Oil
Securely install the new oil filter and replace the oil in your car. Do your research to find out what type of oil is needed for your specific vehicle as well as how many quarts it needs.
Step 5: Allow Oil To Circulate
Turn on your car and let the engine idle for a few minutes before revving it up a few times. This allows the new oil to circulate throughout the engine and any rattling or noise should have subsided due to the lifters being successfully cleaned without having to remove them.
After following this process, your hydraulic lifters should be as good as new! With regular cleaning and maintenance, you can ensure that they’re in excellent condition and keep your vehicle running smoothly.
Finally, make sure not to forget about re-checking your car’s oil level after replacing it. Additionally, if possible inspect your lifters visually afterward–if there is still dirt present then repeat Step 1 again until satisfied with the results. Good luck!
