If you plan to calculate 5.7 Hemi Cam And Lifter Replacement Cost, you need to know that it can be quite expensive, especially when you factor in the cost of labor.
Fortunately, you don’t have to break the bank for this if you know what to look for and where to find it. If your 5.7 Hemi is throwing a misfire code, it’s probable that your lifters have failed.
Although a broken lifter may seem like no big deal at first, putting off a replacement until later might lead to much higher costs.
In this article, we’ll discuss the cost of replacing your 5.7 Hemi cam and the bad lifter, as well as some tips on how to save money while doing so. Read on to learn more about this important part of your engine’s maintenance!
What Are Lifters, And How Many Does The 5.7 Hemi Have?
A lifter is the cylindrical component located between the camshaft and the cylinder valves of an internal combustion engine. The lifter is actuated as the camshaft passes over it, allowing the valve to open momentarily.
In addition, each lifter is dedicated to either the intake or the exhaust valve because of the varying timing requirements for their opening.
A vehicle’s lifter may take on a variety of forms to best suit its needs. The lifters in a pushrod engine, for instance, aren’t actually pressing on the valve itself; rather, they’re activating a rocker arm. Eight front lifters and eight rear lifters make up the Hemi 5.7-liter V8’s total of sixteen.
How Much Does 5.7 Hemi Cam And Lifter Replacement Cost? (Bad Lifters On 5.7 Hemi)
A single 5.7 Hemi lifter replacement will cost you roughly $750 and a new camshaft (roughly $420 from Mopar) at a repair facility.
It is important to shop around because the first time you replace lifters at the shop, you will pay between $450 and $1,000. On the other hand, this may vary depending on the auto shop you visit.
The 5.7-liter Hemi V8 has 16 lifters total, with 8 located up front and 8 in the rear. Installing new lifters in your 5.7 Hemi will cost you about $1,600 on average. Adding a second lifter at the same time will set you back about $100.
If you’re prepared to do the work yourself, replacing the parts for all 16 lifters will cost you around $500.
To top it all off, you’ll need to spend between $50 and $250 on a brand new set of gaskets. The approximate cost of doing it yourself is $800.
Comparing the Costs of Professional vs DIY Replacement
How much would it cost to hire a professional versus do it yourself to replace a hemi cam and lifers? Having a mechanic repair all 16 lifters in a 5.7 liter Hemi engine will cost roughly $1,300 to $1,800 in labor costs and between $600 and $1,000 in parts costs. An adjustable wrench, some box-end tools, and a socket wrench/ratchet are all that will be required.
Their replacement requires a lot of manual labor and will take 6–10 hours. It is recommended that high mileage automobiles employ commercial engine flush and cleaning solutions to remove oil and dirt buildup.
If you’re not sure of your talents, a mechanic should be able to do it for you for around $1,500. The buyer’s location and familiarity with the 5.7-liter Hemi engine’s performance will affect this estimate.
It’s worth noting that some mechanics will give you a price before checking to see if all of your lifters are damaged or if they can be repaired.
If you need to replace your lifters, it’s smart to check with many shops to see if anyone sells a kit that contains everything you’ll need.
Moreover, It costs between $600 and $1,000 to replace a cam lifter by yourself. This price includes the cost of the necessary replacement parts, but not the cost of the tools you’ll need to complete the job.
Functions Of Lifters In Engines
Valve lifters are little cylinders that help keep the engine’s valves open and closed. They are typically cast from iron or aluminum and set up in the lifter galley between the cam lobe and the pushrod.
The lifter is raised by the cam lobe’s rotation and then pushed downward by the pushrod, opening the valve. After completing a cycle, the lifter goes back to its initial position.
For optimal performance, lifters must be custom-made for each engine. To get gas and air into an engine, lifters are required in addition to pushrods.
There are a few different types of lifters that may be used in an engine, including hydraulic, mechanical, and roller, each of which has its own set of pros and cons. Many lifters use a variety of mechanisms to free the valves.
Also, 5.7 hemi is equipped with two main types of lifters: hydraulic, which utilize oil pressure to open the valve, and mechanical, which use gears or rollers to open the valve.
How To Know A Lifter Is Failing?
It’s likely that one or more of your lifters has failed if your 5.7 Hemi displays a cylinder misfire code yet you’ve already changed the ignition coils. An engine’s quivering, ticking, and backfiring might all be signs of many faulty lifters and can worsen as you drive. Also, check out for the following;
- Sounds like the engine is knocking, thumping, or ticking.
- Rough idle.
- Power loss
- The engine made a hissing sound.
- Misfiring engine
If your 5.7 Hemi exhibits these signs, it may have a faulty lifter(s) that will lead to more severe problems if not fixed soon.
How Do You Isolate A Bad Lifter?
If there is a malfunctioning with a lifter in your 5.7 Hemi engine, the ECU will report a code that tells you which cylinder is affected. Troublesome lifters can be isolated and eliminated using a diagnostic scan.
If you take your car to a competent repair shop, the mechanic will conduct the scan to find the bad lifters. Once the cause of the misfire has been isolated, fixing the correct lifter will be a breeze.
An engine flush and cleaning is something that needs to be done often even if you’re the type of driver who likes to handle things on their own.
Professional-grade cleaning agents will do a superb job of eliminating any traces of oil and other debris off your 5.7 Hemi, even if it has seen some use. Vehicles with a lot of miles on the odometer often have lifters that are worn out.
Misfires, especially at ignition, are almost often caused by faulty lifters on a 5.7 Hemi. If your lifters are in good shape, continuing to drive will fix the misfire. If it keeps happening, there could be an elevator issue.
This misfire code suggests a possible mechanical problem. But, a 5.7 Hemi with faulty lifters would show additional symptoms, such as a ticking sounds coming from the motor, in addition to these fault codes.
What Can Happen if I Don’t Replace My Lifters?
You shouldn’t go behind the wheel with broken lifters. This will make your vehicle’s engine misfire and run poorly. If you keep pushing it, the knocking noise from the engine could escalate, resulting in serious damage to the piston heads. There are too many moving elements that interact with the lifters.
And it’s all because of the lifts. It’s bad for the engine since the lifters and other parts will wear out much faster if they’re continually rubbing against one another.
You can damage the camshaft, the valves, and the crankshaft, among other engine components, if you don’t replace the lifters.
You may need to replace the camshaft covers if you continue to drive with broken lifters. The expense of replacing the lifters is minimal compared to the cost of fixing the things that defective lifters can break.
There you have it; all the potential causes of engine lifters noise, lifter replacement cost that have anything to do with hydraulic valve lifters.
Keep in mind that you must muffle all other sounds in order to detect any problems with your engine. As luck would have it, you may easily get effective soundproofing mats.
One way to determine if a physical problem exists with a component of the valve train after ruling out the possibility that the noise you are hearing is caused by loose metal is to perform a brief inspection of the system.
If not, a cleansing agent and oil additive combined with new oil should do the work and make your lifters quiet. You may now take a road trip without worrying that your car’s engine would blow up. Don’t worry about anything but driving.
