The Top 4 Ford Boss 6.2L V8 Engine Issues. The Ford Boss 6.2 V8 made its initial appearance in the 2010 Ford F-150 Harley Davidson and SVT Raptor. The 6.2L V8 survived in F-150 models until 2022, however it was discontinued in F-250 and F-350 Super Duty versions. The 6.2 Boss engine produces 385 horsepower and 430 pound-feet of torque. In comparison to the 6.7 Power Stroke, this may appear to be a letdown. The 6.2L V8 is around $10,000 less expensive and provides a good blend of power and dependability. In this tutorial, we’ll go through some of the most typical Ford 6.2 engine issues and reliability.
Typical Ford 6.2 Engine Issues
Among the most prevalent issues with the Ford 6.2L V8 F150, F250, and F350 are:
- Failure of a valve spring
- Oil spills
- Idle time
- Excessive oil usage
Throughout the rest of the article, we will go over each of the aforementioned topics in detail. But first, a few quick notes. We name these the most frequent problems for a reason. This does not imply that they are widespread issues with the Ford 6.2 gas engine. Rather, these are a handful of the most typical areas where failures occur.
Having saying that, the 6.2 Boss V8 is a fairly dependable engine. There have been reports of these engines lasting 300-400k miles or more with minimal difficulties. At the end of the piece, we’ll return to the Ford 6.2 engine’s dependability.
1) Valve Spring Failures on the Boss 6.2 V8
Valve springs wrap around the valve stems within the cylinder head. They are in charge of delivering spring pressure to the intake and exhaust valves. This keeps the valves from floating or bouncing about. A valve spring is required for each valve, hence the Ford 6.2L V8 has 16 valve springs. Unfortunately, one of the most typical problems with the Ford 6.2 gas engine is valve spring failure.
If you have a valve spring problem, you may notice a variety of other problems. The 6.2 V8 will begin to run rough, throwing misfire codes, and so on. It is also critical to address the concerns as soon as possible. If valve spring failures are not rectified, they might cause more engine damage.
This is a typical problem with the Ford 6.2L F150, F250, and F350 engine. Again, this does not imply that it is widespread. On the internet, a lot of things can be exaggerated. Valve spring issues can and do arise on the Ford 6.2 V8. Look for potential problems north of 100,000 miles.
Symptoms of a Ford 6.2 Valve Spring
On the Ford 6.2 V8, the following symptoms may indicate a broken valve spring:
- Idle time
- Power outage
- Noises of knocking
Symptoms of a broken valve spring are usually obvious. You should expect a rough idle, poor performance, and misfires. Even if only one cylinder has valve spring failure, 6.2 engine misfires can occur on numerous cylinders. Power loss might be difficult to detect because it often affects only one cylinder. You may also notice that the 6.2L V8 makes a knocking or rattling sound.
Valve Spring Replacement for 6.2L V8
To access the valve springs on the Ford F150, F250, and F350 engines, the valve cover(s) must be removed. To remove and replace any damaged valve springs, proper tools are also required. It’s not a difficult DIY, but inexperienced people should leave it to a mechanic.
For the 6.2 V8, valve springs are dirt inexpensive. Each spring will cost around $4-6, or $60-80 for a complete set. Labor costs can quickly pile up, bringing Ford 6.2 valve spring replacement to around $300-700. On a high mileage engine, you might consider replacing all valve springs, which can result in greater replacement prices.
2) Ford 6.2 Oil Leak Issues
Many engines develop oil leaks as they age and accumulate miles. Rubber gaskets can degrade and crack over time due to heat and age cycles. Some recognized faults with the valve cover gasket have resulted in excessive oil consumption. Some Ford 6.2 V8 engines from 2015 to 2016 have leaks from the baffle on the right side valve cover. To fix this issue, Ford issued a TSB.
We are looking beyond that limited sample size. Oil leaks are possible and occur, particularly on older, higher mileage Ford 6.2L Boss engines. One of the most prevalent reasons of oil leaks is the valve cover gasket. Oil pan gaskets and main seals, on the other hand, can cause problems.
We don’t think it’s fair to label this a truly prevalent issue with the Ford 6.2. It is merely the nature of gaskets to degrade and leak during the life of an engine. Aside from a minor fault in 2015-2016 vehicles, there are no design flaws that should result in premature oil leaks. However, certain 6.2 V8 engines will have oil leaks beyond 100,000 miles (age is also a role).
Symptoms of an Oil Leak in a Boss 6.2
Oil leaks on the Ford 6.2 engine might cause the following symptoms:
- There is a visible oil leak.
- Loss of oil
- odors of burning oil or smoke
There isn’t much to say here. Apart from a visible leak, oil leaks rarely create any discernible symptoms. If the situation is severe enough, you may notice that your 6.2 V8 is losing oil at a faster-than-normal pace. This can also result in burning oil smells or smoke coming from the engine bay.
Fix for Ford 6.2L Oil Leak
Of course, the precise cure for 6.2 Boss oil leaks is highly dependent on what is leaking. Leaks in the valve cover gasket and the oil pan gasket are two of the most common problems on the Ford 6.2 F150, F250, and F350. Fortunately, the gaskets are cheap. However, depending on what is leaking, labor costs can quickly build up. Gasket labor should cost between $200 and $500. Moderately experienced do-it-yourselfers should have no trouble completing the fixes.
3) Rough Idle 6.2L V8
Rough idle is a broad topic to discuss. It is also rarely a problem on its own. Rather, harsh idle is a symptom of a larger problem. The Ford 6.2 spark plugs are our major emphasis here. The engine has a total of 16 spark plugs. That’s right, two spark plugs each cylinder. It allows for a lot of possible missteps.
We don’t consider this a true concern because spark plugs are normal maintenance. To digress for a second, we said similar things about oil leaks above because the majority of problems occur at high miles. The point is, the Ford 6.2 engine is dependable, and there aren’t many genuine issues to highlight.
Anyway, let’s get back on track here. Rough idle and other drivability difficulties might be caused by the 6.2L V8 spark plugs. There are numerous other issues that might cause rough idle, such as the valve springs mentioned before. However, with 16 spark plugs, one of them is almost certainly to blame. Most Ford trucks powered by the 6.2 V8 have challenging lifetimes in terms of performance, towing, and so on. This wears out spark plugs, so don’t neglect this fundamental maintenance.
Symptoms of a Ford 6.2 Spark Plug
On the 6.2L Boss, look for the following symptoms, which usually signal a probable spark plug problem:
- Idle time
- Stuttering or hesitancy
- Power outage
On the 6.2 V8 engine, rough idle and misfires are two classic signs of spark plug difficulties. In addition to misfire codes, you may observe a service engine light. Power loss isn’t a significant symptom, especially when only one cylinder has faulty spark plugs. Because several spark plugs rarely break at the same time, if numerous cylinders are misfiring, you may have another problem.
Replacement Spark Plug for 6.2L Boss
Spark plugs are among the most simple to maintain and repair. Even inexperienced DIYers may complete this project in the driveway in a matter of hours. When one spark plug fails, we recommend replacing all of them. If you have an early spark plug failure, this isn’t always the case. However, if they haven’t been replaced in a while, the other spark plugs are probably on their way out as well.
Spark plugs typically cost $7-15 each. It adds a small expense because the Ford 6.2 engine requires 16 spark plugs. Nonetheless, most people can complete this task for $100-150. Add extra $50-150 if you intend to take it to a repair shop.
4) Oil Consumption of the Ford 6.2 Boss
Alright. We’ll be brief on this subject because excessive oil use does not appear to cause any additional issues. The Ford 6.2L V8 has been known to use oil at a rapid pace as it ages. Some people may require a quart or two of oil in between oil changes. It’s normal for engines to use a little more oil as they age.
One area that can cause excessive oil consumption is the 6.2 Boss PCV (positive crankcase ventilation) system. Oil leaks, particularly the valve cover gasket, might also result in faster oil loss (rather than true consumption). Again, there are no serious problems associated with oil usage.
If it is exceedingly severe, it is worth investigating further. With increased age and usage, some cylinders may be losing compression and burning more oil. This is sometimes an indication that the engine is nearing the end of its life. Again, not a typical issue unless you’ve driven over 200,000 or 250,000 miles and the engine is getting fatigued.
6.2 V8 Oil Consumption Reduction
Here are a few tips to help you reduce high oil consumption on the Ford 6.2 Boss engine:
- OCI reduction
- Idle time should be limited.
- PCV system for service
A shorter oil change interval (OCI) can sometimes assist reduce oil usage. Oil grows thinner as it ages, increasing the likelihood of oil blow-by and consumption. Excessive idling contributes to this by shortening oil life; mpg isn’t everything when it comes to useable oil life for the 6.2L engine. Servicing the PCV system or repairing any oil leaks may also be beneficial.
Reliability of the 6.2 Boss V8
Is the Ford 6.2 V8 a dependable engine? The Ford 6.2L V8 engine is a dependable engine in our perspective. It’s designed to power higher-end F150 models like the SVT Raptor, as well as Super Duty trucks like the F-250 and F-350. The majority of Ford 6.2 engines have a harsh life, however “built Ford tough” applies to this engine. We found ourselves writing about issues that aren’t technically widespread ones. Spark plugs are routine maintenance. Oil leaks are a normal part of engine aging.
As a result, we believe the Ford 6.2L V8 is a superb all-around engine. It doesn’t have the same power as the 6.7 Power Stroke diesel. The 6.2 V8 engine, on the other hand, does not come with the $10,000+ price hike and is still a robust, durable engine.
Some 6.2 Boss dependability is simply a matter of luck. We have no control over the fact that not all engines are made the same. We can, however, regulate the maintenance aspect. Change the oil in the 6.2 V8 on schedule, use high-quality oils, and solve issues as they arise. Maintain it properly, and the Ford 6.2 V8 will most likely reward you with a long, dependable life. There are numerous examples of the 6.2L Boss engine lasting 250,000-300,000 miles or more with few or no severe difficulties.
Summary of Ford 6.2 Common Issues
Ford began providing the 6.2L V8 engine in a few high-end performance variants of the Ford F-150 in 2011. It is still used as the base engine in Ford’s Super Duty F-250 and F-350 vehicles. With 385hp and 430 lb-ft of torque, this engine is more than capable for most owners. Those who frequently haul extremely big loads may select the more competent 6.7L Power Stroke. However, it is overkill for most people and comes at a high price, making the Ford 6.2 an ideal choice.
We don’t think half of what we addressed in this essay is even a problem. They’re also not widespread issues that affect a large number of engines. Regardless, no engine is flawless, and the 6.2 Boss is prone to malfunctions and difficulties on occasion. When something does go wrong, the most usual problems are valve springs, oil leaks, and spark plugs. Some engines can consume a lot of oil as they age.
However, if you maintain the 6.2L V8 properly, it will most certainly reward you with a long, dependable life. These engines were designed to withstand a long, hard working life, and they do a very good job of it.
