If you own a 5.7 HEMI engine, you have heard about the newly developed and improved HEMI V8. The HEMI is an American V8 engine family originally developed by Chrysler in 1953 for its Plymouth cars. It was first used in the 1955 Chrysler New Yorker, but it wasn’t until 1962 that Dodge released the first production car equipped with this engine. Since then, there have been many changes made to this engine which have made it more powerful and efficient than ever before!
However, every product has its pros and cons and comes with its own set of challenges; one such example can be found with your 5.7 HEMI motor.
Here are the 7 most commonly experienced problems with 5.7 HEMI engine & solutions to them
1. Sudden Engine Shut Down
- The first thing to check is the fuel pump. If your engine is shutting down and you’ve replaced a fuel pump, there is likely a problem with the pressure regulator.
- If the fuel pressure regulator is OK, then check the fuel filter.
- If neither is causing any issues with your Hemi-equipped truck or SUV, inspect each injector individually for damage or worn seals.
If none of these steps resolves your fuel-related issues, then it’s time to let professionals handle it. If you’re looking for a way to increase the power output of your 5.7L Hemi, try out this best cold air intake system for a 5.7 HEMI charger.
2. Engine Stalls
The following steps will help you troubleshoot a 5.7 HEMI engine stall:
- Check the fuel filter and replace it if necessary.
- Check the fuel pressure in your fuel system by using a gauge on the top of your gas tank or undercarriage of your vehicle, then drive around for 10 minutes until it has returned to normal levels. If this doesn’t work, check other fuel system components (such as injectors).
- Clean out carbon buildup from spark plugs with a wire brush and/or spray cleaner like BreakFree® Fuel System Cleaner (available at most auto parts stores). The buildup can cause problems such as misfires or stalling when starting because it prevents proper ignition of cylinders during start-up; this may also lead to increased wear on pistons.

3. Blown Head Gasket
If your 5.7 HEMI has a blown head gasket, it could be caused by any of the following:
- Oil leak
- Coolant leak
- Extra smoke coming out of the exhaust
Contact a mechanic immediately if you experience any of these issues with your 5.7 HEMI engine. A blown head gasket can cause serious damage to your car and should be fixed immediately!
4. Ticking noise problem
The ticking noise is a common problem in the 5.7 Hemi engine. It’s caused by the valve lifters, and it’s an easy fix to ensure your vehicle runs smoothly again.
The ticking noise is typically heard while idling at low speeds or around town. Still, it can also occur during higher-speed driving. If you’re having trouble hearing this noise, several things could be causing it:
- Dirty air filter – This can cause reduced airflow through the intake system, which causes higher RPMs and could lead to increased tick-tock noises coming from underhood components such as spark plugs or fuel injectors (often located near where these sounds originate).
- Faulty throttle body – The throttle body controls how much fuel gets delivered into each cylinder when its valves open up during combustion processes inside of them; if there’s something wrong with this piece, then it could cause increased wear on other parts over time without fail until eventually breaking apart altogether.
5. Valve issue
The valve issue can be tricky to diagnose, but if you have the right tools and know-how, it’s not too hard to figure out what’s happening.
To check for the valve issue:
Make sure that your car has been started up in neutral. It’s best not to drive around with a broken engine until you’re sure this is fixed!
Make sure that you have a multimeter and know how to use it. If you don’t, get one from a hardware or auto parts store.
Use the multimeter to test the continuity of your ignition coil. If there’s no continuity, then you will need to replace it.
If there is continuity, you need to check the spark plugs. The ignition coil provides voltage to the spark plugs, creating a spark and starting your engine. If this isn’t working correctly, it could be a problem with your spark plugs or wiring.
6. Cam issue
Camshafts are responsible for opening and closing the valves in your engine, so they’re an important part of any HEMI. They’re made of metal, so if they break, you may experience much damage to your vehicle. If your camshaft breaks, it can cause serious issues like:
- The car won’t start
- The car won’t run well
- It will lose power
- It will be difficult to drive
- Your car will overheat
- The car won’t have enough power to drive up hills
- The engine will make unusual noises
You will, in most cases, need to replace the camshaft. Here is the recommended best Cam for a 5.7L HEMI engine.
7. Lifter problem
If you’re experiencing issues with your 5.7 HEMI, it’s important to note several ways a lifter can fail. The most common causes include:
- Lifter failure – this is due to either wear or damage from overheating. Lifters, in particular, are responsible for transferring the power from the crankcase to the pistons during their stroke (and then back again). If worn out or damaged, they won’t work properly, resulting in an engine stall or stalling while driving at low RPMs (which can cause serious problems).
- Camshaft lobe failure – if one of your camshaft lobes has been damaged by something, such as being struck by another object while working on your car, it could lead directly to serious problems! This type of issue would require immediate attention.
