Which 6.7 Powerstroke Years to Avoid? (Problems Explained)

Did you know that the 6.7 V8 Powerstroke is the first of its kind manufactured directly by Ford Motor Company?

The diesel engine made its debut in 2011 Ford trucks. But its beginning was not smooth. The earlier models had serious reliability issues.

So, which 6.7 Powerstroke years to avoid and why? That is the question that comes into customers’ minds after knowing their problems. Without further ado, let me give you the answer backed by data-driven explanations.

Which 6.7 Powerstroke Years to Avoid and Why

What Year Did Ford Put The 6.7 In Trucks?

From the feedback of Ford owners and company information, I came to know that the company was struggling with its 6.0L and 6.4L Powerstroke engines.

Ford was trying hard to solve the issues but failed in some aspects. So, the manufacturer partnered with International Navistar to build their own engine.

After some improvements in the design and production, they successfully built Scorpion 6.7 Powerstroke engine.

And, the engine has been started showing up in the truck since 2011. This variant has got so popular that you can still find them in Ford trucks.

Back then, the engine could deliver up to 390HP and 735 lb.-ft. of torque. Soon after, Ford rolled out an engine update improving the factory tuning.

The upgrade made the same old 6.7L Powerstroke engine capable of providing up to 400HP and 800 lb.-ft. of torque.

Over the years, the engine has become very powerful. In 2011, an F450 DRW could tow up to 24,400 pounds.

But in 2016, the same model has a 5th-wheel tow capacity of up to 31,200 pounds.

Which 6.7 Powerstroke Years to Avoid and Why?

I have gone through lots of forum threads to see the user experience of different 6.7 Powerstroke engines.

After some investigation, I can tell you with confidence that avoiding this diesel engine built between 2011 and 2014 is the wisest choice.

The time duration indicates the first generation of 6.7L Powerstroke engine which had some serious issues. Let me describe those in the next part.  

Drawbacks or Problems of First Generation 6.7 Powerstroke Engines

A diesel engine has hundreds of different parts and components that can go wrong at any time.

The list of problems I am giving here is based on the customer complaints. They are the most common ones faced by Ford Truck owners.

1. EGT Sensor Problem

There is a total of 4 EGT sensors in a 6.7L V8 engine. Any one of them can fail due to various reasons.

You will be glad to know that Ford issues an extended warranty for EGT sensors. Take the opportunity to avoid any expensive repairs.

EGT sensor failure is one of the most common problems of first-generation 6.7 Powerstroke engines.

Don’t think that replacing a problematic sensor is going to last for a long time. If something else is making the trouble, the sensor will fail again shortly.

This kind of continuous issue has been solved in recent years as Ford announced a service bulletin to update the powertrain control module.

2. Clogged EGR Cooler

Seeing engine code P0401 or noticing engine overheating can indicate EGR cooler clogging.

Clogged EGR cooler is another common issue for earlier 6.7 Powerstroke engines like the previous one.

Because Ford changed the EGR system on the new 6.7 model, it was not the problem in 6.0L or 6.4L engines.

As carbon can be deposited in the EGR core easily, it often becomes completely blocked.

The process for replacing the EGR cooler has become a lot easier in the newer models so that you can solve the problem seamlessly.

3. Injection Pump Problem

Due to some design flaws, metal contamination in the fuel system of 1st gen Powerstroke engines is common.

And, it leads to injection-pump failure. Metal-on-metal contact inside the pump causes this issue.

When something like this happens, you may need to replace injectors, regulators, and fuel lines depending on the severity of the situation.

The reassuring fact is that Ford has solved the issue by using a newly designed pump on the 6.7L models starting from 2020 or 3rd generation.

One can identify the problem by experiencing engine stalling, long crank, no start, loss of power, stuttering, or rough idle.

4. Radiator Coolant Leaking

Powerstroke engines have two radiators. Among them, the primary ones in the 6.7L models are more problematic.

In case of seeing low coolant or overheating, it is safe to assume that the radiator coolant is leaking. Upgrading the OEM radiator can solve the problem.

5. Turbocharger Issue

The last common 1st gen 6.7 Powerstroke problem is in its turbocharger. And, it is also because of a design flaw.

Ford tried to achieve higher power and torque by introducing a smaller turbo and it failed miserably.

In the later models, they solved the problem by designing a larger turbocharger.

It has made the engine not only more powerful but also ensured long-lasting smooth performance.

What Year 6.7 Powerstroke Is the Best?

Ford tried their best to improve the performance of its 6.7L Powerstroke engine over the years.

After the end of 1st generation of the diesel engine, they emerged with a near-perfect product in 2015. That is the beginning of the second generation.

So, those who are concerned about the engine’s reliability and have enough budget should buy the engine’s 2nd or 3rd generation model.

From 2015 to 2019, it is considered 2nd gen. 2020 and onwards is considered the 3rd generation.

Why They Are the Best?

Let me tell you the improvements Ford made in this engine in the second generation that made them great.

The company introduced IROX coating on the lower main bearing. It helps improve fuel consumption and reduce carbon dioxide emissions. Actually, the coating is responsible for decreasing friction and wear in the bearings.

Ford updated the fan clutch and gave the engine a heavier crankshaft damper. To support more power and torque in the later models, they made turbo updates. 

The last improvement was in the EGR cooler flow. Altogether, the new 6.7 Powerstroke engines have become a beast on the road.

Overall, the effort was not only meant for making 6.7 Powerstroke more reliable but also increased power and torque to beat the competition.


What Generation Is The 2017 6.7 Powerstroke?

Here, you can get a clear idea about the generations of the 6.7 Powerstroke diesel engine. And, 2017 6.7 Powerstroke falls in the second generation.

Is 2014 6.7 Powerstroke A Good Engine?

As 2014 models fall in the first generation of Powerstroke 6.7L engine, you can safely assume that it has some serious problems. So, no, 2014 6.7 Powerstroke is not a good engine.

Is A 2012 6.7 Powerstroke A Good Engine?

As the first generation of 6.7 Powerstroke engines were made between 2011 and 2014, a 2012 6.7L Powerstroke is not a good engine.

Is A 2011 6.7 Powerstroke A Good Engine?

From the previous answer, you have got the answer. A 2011 6.7 Powerstroke engine is not a good or reliable product. I have described the reasons above.


Have you understood the answer to the question, which 6.7 Powerstroke years to avoid and why? It is easy.

Although 2011-2014 engine production years have produced the most economical products on the line, you must avoid them by all means.

Increase your budget, and go for 2015 or later models to get the best bang for your buck. For maintenance information on this engine, you can check out this link.
