This Ford Boss 6.2 engine made its initial appearance inside the 2010 SVT Raptor and Ford F-150 Harley-Davidson. The 6.2L V8 is no longer an option in F-150 vehicles, although it is still the standard engine in the F-350 and F-250 Super Duty models. The 6.2 Boss V8 engine delivers decent power with 385 horsepower and 430 pound-feet of torque. In comparison to the 6.7 Power Stroke, this may seem to be lacking. The 6.2L V8 engine, on the other hand, costs approximately $10,000 less and provides a good mix of power and dependability. We’ll go through some of the most typical Ford 6.2 engine problems and reliability in this guide.
Among the most frequent problems with the Ford 6.2L V8 engines are:
- Failure of the valve spring
- Leaks of oil
- Idle a little rough
- Excessive use of oil
Throughout the remainder of the essay, we will go over each of the topics above in detail. But first, a few brief remarks. We name them the most prevalent problems for a reason. It does not imply that there are widespread issues with the Ford 6.2 gasoline engine. Instead, these are a handful of the most frequent locations where failures occur.
The 6.2L V8 engine is rather dependable. There have been reports of these engines lasting 300-400k miles or more with minor issues. After the essay, we’ll return to the Ford 6.2 engine’s dependability.
1. Valve Spring Failures on the Boss 6.2 V8
Valve springs are found inside the cylinder head, wrapped all around valve stems. They are in charge of providing spring pressure to the inlet and outlet valves. This prevents the valves from bouncing or floating. A valve spring is required for each valve. Thus the 6.2L V8 engine has Sixteen valve springs. Unfortunately, one of the most frequent problems with the Ford 6.2 gasoline engine is valve spring failure.
If you have a valve spring problem, you may notice a variety of additional issues. The 6.2 V8 will begin to run rough, emitting misfire codes, and so on. It is also critical to address the problems as soon as possible. If valve spring failures are not corrected, they may cause additional engine damage.
This is a frequent problem with the Ford 6.2L V8 engine. Again, this does not imply that it is widespread. On the internet, people may exaggerate a lot of things. Valve spring issues may and do arise on the Ford 6.2 V8. Look for possible problems beyond 100,000 miles.
Symptoms of a Ford 6.2 Valve Spring Problem
On the Ford 6.2 V8, the symptoms may suggest a damaged valve spring:
- Idle a little rough
- Misfires
- Losing power
- Sounds of knocking
Symptoms of a damaged valve spring are typically evident. You will most likely have a noisy idle, poor performance, and misfires. Albeit only one cylinder suffers valve spring failure, 6.2 engine misfires may occur on several cylinders. Power loss may be challenging to detect since it frequently affects just one cylinder. You may also notice that the 6.2L V8 makes a banging or rattling sound.
Valve Spring Replacement for 6.2L V8
You must detach the valve cover(s) on the Ford engines to reach the valve springs. It is also necessary to use the proper tools to remove and replace any defective valve springs. It’s not a problematic DIY, but those who are inexperienced should leave it to a technician.
For the 6.2 V8, valve springs are dirt inexpensive. Each spring will cost about $4-6 or $60-80 for a complete set. Labor expenses may quickly mount up, bringing 6.2 valve spring installation to about $300-700. On a high mileage engine, you may look to replace all valve springs, resulting in higher replacement prices.
2. Ford 6.2 Engine Oil Leaks
As engines age and mileage increases, they are more likely to have oil leaks. Rubber gaskets may deteriorate and fracture over time as a result of age and heat cycles. The valve cover sealing has been linked to excessive oil use in the past. The baffle upon that right-hand side valve covers on specific Ford V8 engines from 2015 to 2016 leaks. To remedy this issue, Ford released a Technical Service Bulletin (TSB).
We’re taking a look beyond that tiny sample size. Oil leaks may and can happen, particularly on older Ford 6.2L v8 engines with greater mileage. One of the most frequent sources of oil leaks is the valve cover gasket. Oil pan gaskets and main seals, on the other hand, may create problems.
We don’t believe it’s fair to label this a widespread issue on the 6.2 V8 engine. It’s just the tendency of gaskets to deteriorate and leak throughout an engine’s lifetime. There are no design faults that should cause early oil leaks, except for a minor problem with 2015-2016 vehicles. However, specific 6.2 V8 engines may develop oil leaks after 100,000 miles.
Symptoms of a Boss 6.2 Oil Leak
Leakage on the 6.2 V8 engine may cause the following symptoms:
- A visible oil spill has occurred.
- Loss of oil
- Smoke or odors of burning oil
There isn’t much to talk about here. Besides a visible leak, oil spills seldom produce any apparent symptoms. If the problem is severe enough, you may notice that your 6.2 V8 is leaking oil at a quicker pace than usual. This may also result in the engine compartment emitting burnt oil odors or smoke.
Fix for a 6.2L Ford Oil Leak
Of course, the precise solution for 6.2 V8 engine oil leaks is very dependent on the kind of leak. The Ford 6.2 F350, F150, and F250, valve covering gasket, and oil pan gasket leakage are two of the most frequent problems. The gaskets, fortunately, are cheap. However, dependent on what is leaking, labor expenses may mount up quickly. Gasket labor expenses should be in the range of $200-500. The repairs should be easy for a somewhat skilled DIYer to do.
3. Rough Idle 6.2L V8
The subject of rough idle is vast. It’s also not typically an issue in and of itself. Instead, harsh idle is a sign of a deeper problem. The 6.2 V8 engine spark plugs are our primary emphasis here. There are a total of 16 spark plugs in the engine. That’s right; each cylinder has two spark plugs. There’s a lot of space for things to go wrong.
Spark plugs are routine maintenance. Therefore we don’t see this as a significant issue. We stated similar things regarding oil leaks above since most problems arise at high mileage to take a detour. The point is that the Ford 6.2 engine is dependable, and there aren’t many genuine issues to address.
Anyway, let’s go back to the point. The 6.2L V8 spark plugs may cause poor idle and other drivability problems. Various additional issues may create a rough idle, such as the valve springs mentioned before. Nevertheless, with 16 spark plugs, one of them is almost certainly to a fault. Most Ford trucks with the 6.2 V8 engine have difficult lifetimes in terms of performance, hauling, and so on. Spark plugs suffer as a result of this, so don’t neglect this routine repair.
Symptoms of a 6.2 V8 Engine Spark Plug
On the 6.2L Boss, look for the following symptoms, which typically signal a possible spark plug problem:
- Idle time is rough.
- stammering / hesitancy
- Misfires
- Loss of power
On the 6.2 V8 engine, rough idle and misfires are two typical signs of spark plug issues. Along with the misfire codes, you may see a service engine light. When just one cylinder has a spark plug problem, power loss isn’t a significant symptom. Because several spark plugs seldom break at the same time, you may have another problem if many cylinders are misfiring.
Spark Plug Replacement for 6.2L Boss
Spark plugs are among the most simple to maintain and repair. Even inexperienced DIYers may do this project in the yard in a few hours. When one spark plug fails, we suggest replacing all of them. If you have an early spark plug failure, this isn’t always the case. However, if they haven’t been changed in a long time, some other spark plugs are probably due for replacement as well.
Spark plugs typically cost between $7 and $15 apiece. Because the 6.2 V8 engine utilizes 16 spark plugs, it adds a little additional expense. Nonetheless, most people can do this task for $100-150. If you’re going to a repair shop, add $50-150 to your budget.
4. Oil Consumption of the Ford 6.2 Boss
We’ll keep this discussion brief since excessive oil usage does not seem to create any additional issues. The 6.2L V8 has been known to use oil at a rapid pace as it gets older. Between oil changes, some people may need to replenish a quart or two. It’s normal for engines to need a little more oil as they become older.
One area where the 6.2 Boss PCV system may cause excessive oil use is the transmission. Faster oil loss may also be caused by oil leaks, particularly the valve cover gaskets (not truly consumption). Again, there aren’t any significant problems associated with oil usage.
It’s worth checking into if it’s very severe. It’s conceivable that individual cylinders are dropping compression and using more oil as they become older and have more miles on them. This may indicate that the engine is approaching the end of its useful life. Unless you’ve driven over 200,000 or 250,000 miles and the engine is becoming fatigued, this isn’t a frequent issue.
6.2 V8 Oil Consumption Reduction
Here are some solutions you can do to improve the 6.2 Boss engine’s excessive oil consumption:
- Shorter OCI
- Idle time should be limited.
- PCV system for service
A reduced oil service interval (OCI) may sometimes help you save money on oil. Oil thins as it ages, increasing the risk of blow-by and consumption. Excessive idling contributes to this since it reduces oil life; when it refers to the 6.2L engine’s usable oil life, mileage isn’t everything. It may also be beneficial to service the PCV system or fix any oil leaks.
Boss 6.2 V8 Reliability
Is Ford’s 6.2-liter V8 engine dependable? The 6.2L V8 engine is, in our view, a solid performer. It’s designed to power high-end F150 vehicles like the SVT Raptor, as well as Super Duty trucks like the F-250 and F-350. The majority of Ford’s 6.2 engines have a hard life. However, this engine is designed by Ford is strong. We find ourselves writing about issues that aren’t exactly prevalent. Spark plugs are a necessary part of routine maintenance. As engines age, oil leaks are unavoidable.
As a result, we think the 6.2L is an excellent engine in every way. It’s not as powerful as the 6.7-liter Power Stroke diesel. The 6.2 V8 engine, on the other hand, does not come with the $10,000+ price hike and still is a robust and dependable engine.
Some 6.2 Boss dependability is just a matter of luck. We have no control over the fact that not all motors are manufactured the same. The issue of maintenance, on the other hand, is under our hands. Change the oil in the 6.2 V8 regularly, use high-quality oils, and solve problems as they arise. The Ford V8 will most certainly provide you a long and dependable life if you keep up with maintenance. Many reports of the 6.2L engine lasting 250,000-300,000 miles or more with few or no problems.
A Summary of Common Ford 6.2 V8 Engine Problems
Ford started selling the 6.2L V8 in a select high-end performance Ford F-150 vehicle in 2011. It currently powers the Super Duty F-350 and F-250 vehicles as the primary engine. With 385 horsepower and 430 pound-feet of torque, this engine is more than adequate for most owners. Those who often pull huge loads may choose the 6.7L Power Stroke. However, it’s overkill for most people and comes at a high price, so the Ford 6.2 is a great alternative.
We don’t think that half of what we spoke about in this post is even close to being an issue. They’re also not very frequent issues that impact a large number of engines. Nevertheless, no engine is flawless, and the 6.2 engine is susceptible to malfunctions and problems from time to time. Spark plugs, valve springs, and oil leaks are the most frequent problems when anything goes wrong. Some engines can use a lot of oil as they become older.
However, if you properly maintain the 6.2L V8, it will undoubtedly provide you with a long and dependable life. These engines were designed to last a long, hard-working life, and they do a fantastic job at it.
