Is the Dodge 4.7 a Good Engine?

Every engine has advantages and disadvantages, but 4.7 is a good option. In my prior truck, I had one, and it never failed me.

These engines are simple to maintain and, if not intentionally destroyed, can last if a hemi.

Dodge 4.7 engine has a solid cast-iron bedplate and block, as well as a limited number of computer systems and dependable timing chains.

Both of my pickups had more than 250k miles on them. Most importantly, that oil must be changed regularly. Dodge 4.7’s issue is that they despise being in the heat.

They also have the issue that if your engine water is not replaced regularly, rusted material from your engine block will clog in the radiator, resulting in greater temperatures.

What Are the Common Problems with a 4.7 Dodge Engine?

01. Engine Failure

Engine failure is the most common complaint among drivers. If you take exceptionally safe care of your car`s engine and do not forget to maintain it regularly, it will last you a long time.

Dodge 4.7-lit has an average lifespan of 100K miles. Typically, problems with engine breakdown begin around the 70K-mile mark. So, what would you do to stay away from this?


To try to cut costs, some experts advocate changing various pieces of the motor (a new engine will be expensive).

However, if the item is quite old, it is preferable to consider replacing it entirely. An aftermarket engine will not break the bank if you are driving an ancient Dodge vehicle or SUV.

02. Oil Buildup

Oil buildup is also known as oil sludge, and it occurs when the oil in the engine becomes too thick, preventing the motor from performing at its best.

And when the oil gets heavier, it clogs up everything else in the engine block. If the problem is severe enough, the automobile will simply not start.

Engine and gearbox failure regularly are clear indicators that it is time to change the oil.


Do not skimp on the quality: invest in a well-known brand of high-quality oil. That should ideally be synthetic.

A complete oil change, unfortunately, does not always resolve the issue. You may need to address some ventilation issues.

Of course, I am referring to the crankcase and the PCV. Allow a mechanic to take care of it if you are not up to it.

03. Oil Forming

Most drivers will never encounter oil forming, but if you do, you will immediately recognize that something is amiss.

There will be a bunch of foaming in the oil, but it will not be on top of it; rather, it will be at the bottom. What exactly does that imply?

Well, there is a lot of air in there with the oil, which is bad news. One of the engine’s worst adversaries is air. But the air bubbles could be little. Another explanation for this is humidity.


My recommendation to you is to make sure your engine is warm before starting your car. But it is the air that is wreaking havoc; let us see what we can do about it.

As previously stated, good-quality oil can solve a variety of engine issues.

However, if the bubbles are not going anywhere, the vacuum seal or casing is most likely destroyed. If that is the case, go to the nearest auto shop.

04. Overheating

Overheating is common in hot & humid climates. Off-roading affectionate, who continually strain the powertrain to its limits, frequently worry about overheating.

Lack of effective air filtering is the leading cause of an overheated engine. While the factory production is adequate, it is not without flaws. Investing in an extra air intake kit is the best answer for this.


Your engine`s input tube will enhance airflow significantly, while the in-built filter will keep trash and dust out of the engine, extending its life.

A less expensive option is to use coolant. Make sure you check your equipment regularly.

Pay special attention to the gauges, as they will be the first to notice a problem. Your engine will get “rumbly” as a result, which is another telltale indicator.

05. Ticking Sounds

If you have had to cope with a vexing ticking noise emanating from your car’s engine, it is a hard one because it might suggest a significant problem at times and nothing serious at other times.

Begin with a diagnosis, as is customary. Your engine is short on lubricant; add more oil, and the noise should go away (hopefully).

If you are lucky, simply running your engine for about one or two minutes to warm it up may be enough to fix the problem.

06. Head Gasket Failure

With time and usage, head gasket issues on a 4.7L engine may occur naturally. Overheating, on the other hand, is the most typical reason for head gasket failure.

If an engine is allowed to overheat for an extended period, it will always develop head gasket difficulties. Dodge 4.7 engine is far less forgiving than other engines.


That is why the cooling system issues were brought up first. If you suspect a problem with the cooling system, pull over to a safe location right away.

Do not take any chances and hope to complete the last few kilometers of your journey.

Without minding whether your engine has overheated, the 4.7 head gasket is subject to failure.

However, if you already have a cooling issue, it is advisable to err beside the caution and avoid risking a head gasket failure. Repairing a head gasket is not cheap.

We do not advocate doing this yourself because it is a long and difficult operation, and if you do not know what you are doing, you could end up causing more harm to the engine.

If you need to change the head gasket, you do not have a choice except to pay the high price. Make an appointment with a technician.

07. Valve Cover Leaks

Originating from the BMW world, we are well-versed in oil leaks from valve covers and valve cover gaskets.

Oil leak is a regular problem with the 4.7L engines, particularly as they get older and have more miles on them.

As the gaskets produce microscopic fractures, oil leaks are usually minimal at first. However, if the leaks are not repaired, they will get worse over time.


It is not an emergency fix and driving for a brief period with a valve cover leakage is not a big deal. We still advise that you rectify the leak as soon as possible.

Based on where oil is pouring from, it could spark a fire or deteriorate other components. Because a Dodge 4.7 V8 is almost 12 years old, leaks can happen at any mileage.

Leaks from valve cover gaskets are particularly common northward of 100,000 miles. Short-distance engines are also more vulnerable due to the continuous heating & cooling of the gaskets.

08. Valve Seat Failure

Sometimes the valve seats on some 4.7L engines may be defective. We will skip the technical talk if you are unfamiliar with valve seats.

But the valve seats’ role is to help seal the inlet and the exhaust valves when they are closed, as shown above. If these valve seats fail, the inlet valve will not seal entirely.

As a result, this causes a decrease in compression, especially in the Jeep 4.7L. Most cylinder will just leak air as the attempts to compress during the compression stroke.

Valve seat failures is a major issue with significant implications for engine performance. Valve seat failures can have serious repercussions if left neglected for an extended period.

Overheating is the primary cause of valve seat and head gasket failures. Another cause to be cautious about is if your water system malfunctions or overheats.

In any event, valve seat issues can and do arise. However, because these things are prone to be exaggerated on the internet, it may not be fair to label them a frequent problem.

In fact, this problem is restricted to early 4.7L engines.
