5.7 Hemi Cam And Lifter Replacement

The 5.7 Hemi Cam and Lifter replacement is a straightforward process that can be accomplished with basic tools and minimal mechanical knowledge. Begin by draining the oil from the engine and remove the front cover, timing chain tensioner, camshaft retainer plate, lifters, rockers arms, pushrods and any other components that are connected to the camshaft assembly. Once these have been removed you can then replace the old camshaft with a new one of your choice along with new lifter buckets if applicable.

Reassemble all components in reverse order of removal being sure to torque all bolts/nuts according to factory specifications. Finally refill engine oil and start it up for test drive!

Replacing the cam and lifters on a 5.7 Hemi engine can be a daunting task for those without experience, but it is an essential part of keeping your vehicle running smoothly. The process involves removal of the cylinder heads, inspection and resurfacing if necessary, replacing the camshafts, adjusting valve lash and reinstalling the cylinder head components. With careful attention to detail and proper tools, this job can be completed in as little as 4-6 hours with no need for specialized equipment or expertise.

Taking care of this maintenance now could save you from expensive repairs down the line!

How Much Does It Cost to Replace a Cam in a 5.7 Hemi?

Replacing a cam in a 5.7 Hemi engine can be an expensive process, depending on the model of your vehicle and what parts you need for the replacement. Generally, it will cost anywhere from $1,000 to $2,500 or more for labor alone when replacing a camshaft in this engine. This does not include additional parts such as gaskets and seals which may be necessary during the repair; these components can add another few hundred dollars to the total cost.

The actual cost of a new camshaft depends on where you purchase it from and whether it is performance-grade or OEM quality; expect to pay at least around $300 for one of these parts regardless of quality grade. Lastly, if you are having trouble finding any specific part needed for your 5.7 Hemi engine rebuild, consider consulting with an experienced mechanic who should be able to provide advice on where best to source the correct components at competitive prices.

Why Do 5.7 Hemi Lifters Fail?

The 5.7 Hemi lifters are an integral part of the engine, providing timing and lift to your vehicle’s pistons. Unfortunately, over time they can become worn out or fail entirely due to a number of factors, including excessive heat, inadequate lubrication, debris contamination, and more. When this happens, you may experience poor performance from your engine as well as noises such as ticking or knocking coming from within the motor itself.

The most common cause of failure with these lifters is that their internal components – such as their valves – have become clogged up with dirt particles or oil sludge. This prevents them from operating correctly by not allowing enough air and fuel into the combustion chamber at the right times during each cycle of operation. Additionally, if too much pressure builds up inside these components it could lead to premature wear on other parts in your engine like camshafts and bearings which would result in further mechanical problems for you down the road.

What Years Did the 5.7 Hemi Have Cam Issues?

The 5.7 Hemi V8 engine, introduced by Chrysler in 2003, has had its share of issues with camshafts over the years. During the early model years (2003-2007), there were reports of camshaft wear and premature failure caused by design flaws. The issue stemmed from a combination of insufficient lubrication to the camshaft lobes and an inability for some parts to handle high RPMs generated by performance modifications.

This led to increased friction which eventually caused lobe deformation or complete lobe failure resulting in reduced power output and engine noise. The problem was so widespread that many aftermarket companies developed solutions such as better lubricants, improved oiling systems, and more durable cams for these engines. Thankfully, these problems were addressed when Chrysler released an updated version of their 5.7 Hemi in 2008 with revised internals that allowed it to withstand higher RPMs without suffering from camwear or premature failure issues like previous models did.

How Common is Hemi Lifter Failure?

Hemi lifter failure is more common than one might think. While it’s not a frequent occurrence, it does happen and can lead to severe engine damage if not addressed properly. There are several factors that can contribute to the failure of Hemi lifters including wear and tear from normal use, oil contamination, and improper installation or maintenance.

The most common cause of Hemi lifter failure is inadequate lubrication as this causes excessive friction between the parts leading to premature wear-down. Additionally, any foreign particles in the oil such as dirt or debris can also cause damage due to their abrasive nature which wears down the components further over time. Furthermore, incorrect adjustment of hydraulic pressure when installing new Hemi lifters can also result in an early fail point due to too much strain being placed on the part itself.

Ultimately, while Hemi lifter failures are relatively rare compared with other engine issues they do happen occasionally so regular maintenance checks should be conducted to ensure that everything is running properly and reduce potential risks associated with these components failing prematurely.

5.7 Hemi Lifter Replacement Without Removing Head

Replacing the lifters in a 5.7 Hemi engine without removing the head is possible with some specialized tools and procedures. This method requires a special tool to compress the valves, as well as removal of the valve covers and rocker arms for access to the lifters. Once these are removed, it’s possible to use a suction cup or special tool to remove each individual lifter and replace it with an identical one.

After that process is complete, reassembly of all parts can be completed prior to starting up your engine again.

2012 5.7 Hemi Cam And Lifter Replacement Cost

Replacing the 5.7 Hemi Cam and lifters in a 2012 model year vehicle can be a costly endeavor. Depending on what parts are needed, labor costs, and additional accessories or services required, the total cost of replacing these components ranges anywhere from $1,000 to upwards of $3,500 or more. It’s important to make sure you get an accurate quote before starting this type of repair job so you know exactly what the final price will be.

6.4 Hemi Lifter Replacement Without Removing Head

If you own a 6.4 Hemi engine, it’s important to know that lifter replacement can be done without removing the head. To do this, you’ll need to remove the valve covers and rocker arms before draining the oil from the pan. Once drained, loosen all intake manifold bolts and remove them along with any accessories attached to it such as fuel lines or spark plug wires.

Then you can begin replacing each of your lifters one at a time until they are all replaced. Finally, when putting everything back together make sure to use new gaskets for a proper seal and fill your engine up with fresh oil to finish!


This blog post was a great guide for those who are looking to replace the cam and lifters in the 5.7 Hemi engine. By following these steps, you can be sure that your replacement will be done correctly and that it will last for many years. Additionally, if any further assistance is needed there are plenty of resources available online or at your local automotive store.

With proper care and maintenance, this 5.7 Hemi engine can provide excellent performance without having to worry about frequent repairs or replacements.
