About Chevrolet aka Chevy
When it comes to manufacturing the highest quality cars, Chevrolet or Chevy is considered one of the best in the world. It is an American automobile division of the American manufacturer General Motors. The company itself has been in existence since 1911. It is a genuine giant in the automotive industry.
Chevy manufactured many iconic cars even back in the 1970s and 80s. Moreover, the brand has produced several classic cars over the years that are much loved by the people even after so many years. Thus, surpassing Chevrolet in terms of quality and performance has always been a challenging task for the various car manufacturers around the world.
However, despite manufacturing quality products for so many years, the products from Chevrolet are not without some problems. Throughout their long history, there have been quite a few problems with Chevy engines. Furthermore, these problems have led to many financial losses for the company as well.
Chevy 6.0 Engine Lifespan
The usual Chevy 6.0 can last a very long time if you treat it with appropriate care and caution. General Motors does not have any set millage where they anticipate when the engine will be out of order. I think it is reasonable to expect more than 150,000 miles out of this gas engine with proper maintenance and use of good engine oil. Besides, it’s the components such as alternators, water pumps, power steering pumps, etc. that have the probability of creating the most problems.
Chevy 6.0 Engine Features
The Chevy 6.0 gas engine is manufactured for heavy-duty applications. This also includes iconic models such as the GMC Sierra and Chevrolet Silverado. The mild compression ratio and the flat torque curve is suitable for heavy-duty vehicles such as trucks. Moreover, the torque ratings and lower horsepower help in improving reliability and fuel consumption.
The coil-near-plug ignition system comes with a 4x cam sensor, crankshaft position encoder, and knock sensors to work in all conditions offering control on ignition timing. The Iridium-tipped spark plugs promises extended life and offers improved properties of self-cleaning, thereby decreasing any plug fouling potential.
Chevy has ensured an improved intake flow and this greater flow is assured with the exhaust ports. The effectiveness of the engine enhances the emission performance. The high-temperature exhaust valves offer long-term durability, and the floating pin pistons increase durability and reduce noise. The long-term durability is also associated with quiet operation due to new leaf spring dampener coming with the heavy-duty timing chain.
Furthermore, it offers a cast-aluminum oil pan to offer additional rigidity. This cast-iron cylinder blocks deep-skirt with main bearing six-bolt caps to restrict crankshaft flex such that the structure of the engine is stiffened. Also, there is steel fuel rail which ensures return-less fuel injection.
The cylinder head is cast in aluminum. Chevy used the variable valve timing to suit low-end torque and for high rpm horsepower as well as advanced cam timing. There is electronic throttle control compatible software in the engine control module too.
The Chevy 6.0 gas engine is considered to be a workhorse engine. The valve timing is variable and helps in optimizing efficiency, performance, and emissions. Chevy also offers hydraulic roller lifters, steel camshaft, and steel roller rocker arms to offer excellent durability and reduced friction. Its shallow sump oil pan suitable for marine applications.
The external crossover water is combined with water pump casting such that coolant does not flow through the manifold of composite intake.
The Chevy 6.0 engine is powerful, delivering high strength with exceptional refinement.
Now, let us discuss some common problems of the Chevy 6.0 engine. If you are familiar with these problems, then you can just solve the problems yourself or with the help of a good mechanic.
Chevy 6.0 Engine Problems and Solutions
In any vehicle, the engine is regarded as the most essential component. It is the heart that makes it possible for the whole body to keep moving. As it is a mechanism, it is normal for it to have some problems. The problem can be sometimes rare and sometimes common.
Chevy 6.0 engine is not an exception in this regard as well. In order to take proper care of the engine you need to know about these problems. So, let’s talk about the problems that you may face if you own a Chevy 6.0 engine-
First and foremost, we will talk about the problems that happen due to oil pressure as well as the possible solutions to these problems.
Sometimes you may see a light due to low oil pressure. It is a common complaint in the GM vehicles 2007-2016 vehicles that have a V8 engine. It is also known as DOD (displacement on demand). The symptoms occur with no engine-related noises during a low oil pressure condition.
The solution given by many expert mechanics is to replace the oil pressure sensor. This will eliminate the message of low oil pressure. This certainly does not solve the issue itself, and it is assumed that there is a severe engine problem. Therefore, the mechanics may suggest major engine repairs. But, it can also fail to eliminate the symptoms.
The second problem related to oil pressure is that you receive a low oil pressure indication. This is often very surprising and very confusing.
As a solution, the mechanics may try to eliminate the symptom by changing the oil and filter. In case this fails, the vehicle is then sent for evaluation to the dealer. Once there the mechanic replaces the filter screen and the oil pressure sensor. It eliminates the message of low oil pressure as a result.
Another problem is that you may be suddenly informed that there is an incorrect installation of the lubricant and aftermarket oil filter in your vehicle. This may come as a matter of great disappointment to you. As a result, you might have no choice but to request compensation for the repairs from the lube shop.
However, there is a possibility that the problem is in your engine. There is usually a screen known as the valve-lifters filter on GM applications with AFM. The purpose of this filter screen is to filter the oil and to control contamination affecting the AFM hydraulic system.
When this screen gets filled with sludge or debris and restricts the oil supply, it shows a low oil pressure message.
The possible solution for this problem is to clean the filter screen or to replace it.
Now, let us further discuss other common problems that may occur in your Chevy 6.0 engine.
Problem: Tapping Valves
This type of problem occurs when the Chevy 6.0 engine comes back to work after resting for a long time such as when it is used as a crate replacement or at the time of restoration. After resting for a considerable amount of time it may produce a tapping or clicking sound when you run it.
This problem is generally caused by low oil pressure or due to blockage of the oil galleys.
In case this problem happens, you’ll have to replace the oil pumps and clear the oil galleys. You may do this with the help of an experienced mechanic to make your engine run smoothly without facing any problem. You can also make sure that you drive it at least twice or thrice a month if you want to avoid it from happening again.
This problem is a problem that is common in any kind of engine, not just in Chevy 6.0 engines. Any engine can create misfire if a technical problem occurs. In an engine, there are three components needed for fire – oxygen, fuel, and spark. These three elements are essential for keeping the engine running. Furthermore, you cannot expect any of these elements to be under your complete control.
Engine may face many serious problems when a misfire happens. It may damage the engine pretty severely. You may see more emissions and less fuel efficiency as a sign of possible misfire. This problem happens in a few other Chevy engines as well.
If your vehicle creates misfire, the first thing you should do is to see a mechanic.
You may face this problem with your engine during the cold months of the year. It frequently happens when the temperature is near the freezing point.
The reason for this type of problem is the failure of starting the engine. This problem is generally found to be with the automatic choke being in a closed state.
When you’ll face such problems starting on cold days, you should check the engine compartment. If you can smell gasoline there, the problem is probably with the automatic choke plate.
To solve this problem you may have to remove the air cleaner and inspect the choke plate. If the plate is closed, the problem is here. Make sure that it swivels to close and open. Open the choke plate a bit, at least 1/8 inches to get rid of the problem.
There are instances where you may hear some unrecognizable sound from the Chevy 6.0 engine under your car’s hood. The sound itself is quite normal and may occur because of some technical problems but that is not a major issue. It won’t affect the performance of the engine. This small tapping sound is being produced from the camshaft, but it can be very irritating for new owners.
When you hear this sound it would be better if you check and be sure if the sound is really coming from under the hood. You can ignore it if the sound is low and comes from the camshaft.
That might not be the same sound we are talking about. Whenever you hear a new kind of sound coming from under the hood, let a trusted mechanic check the whole engine.
“Reduced Engine Power” Warning Light Problem:
Sometimes you may get the red ‘reduced Power’ or ‘reduced engine power’ warning without any valid reasons. This shows up because of many problems. However, in Chevy 6.0 this type of problem mostly happens when there is an issue or malfunction in the throttle. It can also occur if the throttle body is defective or flawed as well. It may be due to a flaw in the electronic system, faulty wearing, or carbon accumulation within the throttle body. Inspect the vehicle and make sure that the throttle body wiring is okay, and not stretched or pinched.
You have to seek the help of expert mechanics in case this problem happens. They can inspect the codes on the computer of the vehicle using a scan tool or code reader. That way, they can find out where to start and can diagnose and solve the problems.
“Check Engine” Light Problem:
Similar to ‘Reduced Power’ warning light, the ‘Check Engine’ light is another warning light that tells you to check the engine. This light might warn you about a lot of problems. Usually, this warning light tells you that there may be some issue in one of the monitored systems of the vehicle. In this case, you should check your vehicle to see if there are any problems.
You can check the fuel cap, the fuel filler neck top or the Emission Control and Recovery (EVAP), and see if they are loose, faulty, or damaged. When you can’t find any problems even after checking, going to a mechanic would be a good idea.
Go to a trusted mechanic and leave the fixing in this hand. A capable mechanic will find out the exact problem and take the necessary steps to solve it.
Used Engine Problems:
Usually, a used but well maintained Chevy 6.0 engine can give its new owner a really great performance when installed in a vehicle. However, it is important that you should have sufficient knowledge about the engine’s usage history, or you may find yourself facing some issues that may be very unsavory. In case there are some issues, the engine may overheat. Although, this may also happen due to thermostat or radiator problems than engine problems.
Keep in mind before buying, that you have to determine whether the radiator perfectly matches your car or not. Especially, you must consider the possibility of the engine coming from a car of an entirely different model or make. It is also possible that the thermostat may have been installed previously.
Ways to Increase Engine Lifespan
