If your 5.7 Hemi is giving you an engine misfire code, there is a possible chance that one or multiple of your lifters have gone bad. Having a broken lifter may not be an immediate sign of trouble, but not replacing your lifter as soon as possible could end up costing you a lot more in the long run.
The average cost to replace a single 5.7 Hemi lifter at an auto shop is around $750. However, this price can vary depending on the shop that you take your car to.
Most shops will charge anywhere from $450 to $1,000 for the first lifter replacement, so getting multiple quotes is important.
The Hemi 5.7 Liter V8 has 16 lifters, with 8 front and 8 in the rear. Replacing all the lifters on your 5.7 Hemi will cost you an average of $1,600. Each other lifter you get replaced at the same time will cost about $100 apiece.
If you are comfortable doing the work yourself, the cost of parts for all 16 lifters will be around $500.
You will also need a new set of gaskets which can be found for about $50 on the low end and $250 on the high-end. The total cost to do the job yourself is around $800.
No matter who replaces your lifters, it’s essential to have them adequately lubricated when they are installed. Lifter damage is often caused by a lack of lubrication and incorrect installation.
Replacing the lifters without properly lubricating them can lead to premature failure and even more expensive repairs.

What Are Lifters for in my Engine?
Lifters are small, cylindrical pieces in an engine that help maintain valve control. They are commonly made of aluminum or iron and sit in the lifter galley between the cam lobe and the pushrod.
As the cam lobe moves, it pushes on the top of the lifter, which then pushes down on the pushrod, which opens the valve. The lifter then bounces back into its original position, ready for the next cycle.
Multiple different types of lifters can be used in various kinds of engines. Without lifters, pushrods would not be able to open the valves to let fuel and air into an engine.
The various types of lifters that can be used in an engine are hydraulic, mechanical, and roller lifters. Every kind of lifter uses a different method to open the valves.
Hydraulic lifters use oil pressure to open the valve, while mechanical and roller lifters use spinning gears or wheels to open the valves.
Signs my Lifter(s) Are Failing
If your 5.7 Hemi gives you a cylinder misfire code and you’ve had the ignition coils replaced, one or more of your lifters has likely gone bad. You can expect to see an engine with multiple failed lifters start shaking, ticking, and backfiring while driving, which will worsen over time.
In addition to a cylinder misfire code, you may also see one or more of the following codes:
In addition to a cylinder misfire code, you may also see one or more of the following codes
P0300 – Multiple Cylinder Misfire
P0301 – Cylinder 1 Misfire
P0302 – Cylinder 2 Misfire
P0303 – Cylinder 3 Misfire
P0304 – Cylinder 4 Misfire
P0305 – Cylinder 5 Misfire
P0306 – Cylinder 6 Misfire
P0307 – Cylinder 7 Misfire
P0308 – Cylinder 8 Misfire
These codes are all caused by the same issue, so replacing one or more of your lifters can solve these issues. If you see any of these codes, it’s necessary to have your vehicle serviced as soon as possible.
What are the Symptoms of a Bad Lifter?
Besides the codes mentioned above, you may also experience some or all of the following symptoms
Engine knocking, tapping, or ticking noise
Loss of power
Hissing noise from the engine
If you experience any of these symptoms, your 5.7 Hemi may have a faulty lifter(s), leading to more severe problems if not taken care of immediately.
How Do You Know Which Lifters Are Bad?
The best way to determine which lifters are deficient is to have a diagnostic scan performed on your vehicle. This will give the technician a better understanding of where the misfire is coming from. They will then isolate which cylinder(s) are having issues and replace the appropriate lifters.
If you’re thinking about replacing the lifters yourself, consider using professional-grade engine flush and cleaning products that will remove the excess oil and dirt from your 5.7 Hemi engine.
This is especially important if your engine has high mileage on it and may be one of the reasons you’re experiencing lifter failure.
The best way to tell if your lifters are failing is to first determine if your vehicle has a misfire, especially on startup. If the misfire does not go away after running for some time, you could have failed lifters.
As mentioned earlier, codes typically indicate these issues but may also be evident through irregular engine noise and loss of power.
How Long Can You Drive With Bad Lifters?
You can expect to drive with bad lifters for around 50-100 miles before you start experiencing very noticeable problems.
If you continue driving your vehicle after 100 miles, you may experience severe engine damage and require a rebuild or replacement.
If this is the case, you can expect to pay around $4,000-$6,000+ to have your 5.7 liter Hemi engine replaced, which is why it’s crucial to have your lifters replaced as soon as possible.
The cost of an engine replacement by a mechanic can be from $5,800 to $13,000, depending on the mechanic and if they put in a brand new engine or rebuild the old one.
What Can Happen if I Don’t Replace My Lifters?
If you do not replace your lifters, the engine will run rough and misfire constantly. It’s also likely to knock loudly while running, leading to piston head damage if this goes on for too long.
The lifter comes in direct contact with multiple moving parts inside the engine, and if these parts collide, it will create a lot of friction.
This can quickly wear out the lifter and other engine components. Replacing your lifters is a much cheaper alternative to repairing or replacing other damaged engine parts.
Not replacing your lifters can damage other parts of your engine like the camshaft, crankshaft, and valves. It can also cause excessive wear to the camshaft cap, which would need to be replaced when replacing your lifters.
How Much Does it Cost to Replace the Lifters in a 5.7 Hemi?
Replacing all 16 lifters on a 5.7 Hemi engine will cost $1,300-$1,800 by a mechanic or $600-$1,000 if you do it yourself. The only tools needed are an adjustable wrench, box-end wrenches, and socket wrenches/ratchet.
Since this is a labor-intensive process, the total time spent replacing them will range from 6-10 hours. If you have a high-mileage engine, it’s recommended that you also use professional-grade engine flush and cleaning products to clean out the old oil and dirt.
If you’re not comfortable doing this yourself, most mechanics should be able to do the job for around $1,500. This price range can vary depending on where you live and their overall experience with the 5.7 Hemi engine.
Note: Some mechanics will give you an estimate without checking to see which lifters are damaged or if all of them need replacing, but that is generally backward for this job.
Some car parts shops may offer a convenient package deal if they carry the products you need to replace your lifters, which is why you should call around and find out what each shop has to offer.
Cost of Replacing the Lifters on your Own
