Is Ford 6.8L V10 a Good Engine? Problems, Life Expectancy & Specs

This powerful engine is commonly found in Ford trucks and is often mistaken for the larger 7.3L diesel engine. However, it's important to note that the 6.8L V10 engine is actually a gasoline engine.

One great thing about this engine is that it's pretty easy on your wallet when it comes to oil changes. The V10 engine holds around 6.5-7 quarts of oil, which means you won't have to spend too much money on oil changes.

Ford Triton V10 Engine Specs & Horsepower

Ford makes the Triton V10, and it has been in production for a number of years, so it's a well-established engine that's been tested and refined over time. The cylinder block and head are made of cast iron, which provides a solid foundation for the engine.

The Ford 6.8L V10 engine is fueled by gasoline and uses a multi-point fuel injection system to ensure that the fuel is distributed evenly and efficiently. It has a V10 configuration, which means that it has 10 cylinders arranged in a V-shape. This configuration is great for providing a lot of power, as it allows for more cylinders than a typical V8 engine.

Each cylinder has 2 valves, which are operated by an overhead camshaft. This layout is known as a single overhead cam (SOHC) valvetrain, which provides a good balance between performance and complexity. The bore of the cylinders is 90.2 mm, and the stroke is 105.8 mm, which gives a total displacement of 6,797 cc.

The Ford 6.8L V10 has a compression ratio of 9.2:1, which is fairly low for a gasoline engine. This helps to ensure that the engine runs smoothly and doesn't experience any knocking or pinging. The engine produces 362 horsepower and 457 lb-ft of torque, which is more than enough to tow heavy loads or haul large equipment.

It weighs in at around 600 pounds, which is fairly heavy for a gasoline engine. However, this weight is necessary to provide the necessary strength and durability for heavy-duty applications. The firing order of the engine is 1-6-5-10-2-7-3-8-4-9, which is a bit more complex than some other engines but is still easy to work with.

The engine requires 5W-20 engine oil and has an oil capacity of 6.5 liters. The oil should be changed every 7,500 miles to ensure that the engine remains in top condition. The Ford 6.8L V10 engine is a powerful and reliable engine that's perfect for heavy-duty applications. If you need an engine that can handle big loads and tough jobs, this engine is definitely worth considering.

Possible Problems with Ford 6.8 Triton Engine

The Ford 6.8 Triton engine is the power plant of choice for many Ford enthusiasts. This engine has been around for quite some time and has proven itself to be reliable, but there are a few issues that you need to be aware of.

Blowing Spark Plug


One of the main issues that people have with the Ford 6.8 Triton Engine is spark plug blowout. This occurs when the spark plugs are not held securely in place, which can cause them to pop out of the engine. This is because the V10 engine didn't have enough threads in the heads to hold the spark plugs in place, which caused the plugs to pop out.

To prevent spark plug blowout, use a thread-locking compound on the spark plug threads. This will help to keep the spark plugs in place and prevent them from popping out. You should also ensure the spark plugs are torqued to the correct specifications.

Cracked PCV Hose


Another issue you might encounter with the Ford 6.8 Triton Engine is a cracked PCV hose. The PCV (Positive Crankcase Ventilation) system removes blow-by gases from the engine crankcase. Over time, the PCV hose can crack and cause a vacuum leak, leading to rough idling and reduced engine performance.

To prevent a cracked PCV hose, you should inspect it regularly and replace it if it shows any signs of wear and tear. You should also make sure that the PCV valve is working correctly and that the hose is properly connected.

Exhaust Manifold Failure


The exhaust manifold on the Ford 6.8 Triton Engine can fail over time. The exhaust manifold is responsible for collecting exhaust gases from the engine and routing them out of the vehicle. Over time, the manifold can develop cracks or leaks, which can cause a loss of engine performance and increased emissions.

To prevent exhaust manifold failure, you should regularly inspect it and replace it if it shows any signs of wear and tear. You should also make sure that the manifold bolts are properly torqued and that the manifold gasket is in good condition.

Ford 6.8L V10 Engine Life Expectancy

The Ford 6.8L V10 engine has a life expectancy of around 200,000 miles. This can vary depending on a few things, including maintenance, driving style and conditions. In addition to these factors, it's also important to note that some specific engine components may have a shorter lifespan than others. For example, the spark plugs on the V10 engine are known to have issues with blowouts, which can lead to engine damage. However, this can be prevented by using a thread-locking compound on the spark plug threads and making sure they are torqued to the correct specifications.

Is a V10 engine stronger than a V8? 

Absolutely! V10 engines are known for producing more power than their V6 and V8 counterparts. You see, an added cylinder means a larger and heavier engine that will inevitably burn more fuel. But with that extra heft comes extra power. Of course, you can always modify a smaller engine to achieve the same output, such as with turbocharging or supercharging.

Is the 6.8 V10 a diesel?

No, it's not a diesel engine, but it's still pretty mighty. In fact, Ford's 6.8-liter Triton V-10 is one of our favorite gasoline engines because of its diesel-like performance. So even though it's not a diesel, it's still a force to be reckoned with.
