Preferably steer clear of early Powerstroke 6.7 versions from 2011, 2012, 2013, as well as 2014. The 6.7 diesel engines’ shaft lubrication is insufficient, which leads to metal grinding on metal. Following that, pieces enter the injectors and motor circuits. Metal contamination may cause damage to lines, injectors, regulators, fuel systems, and more.

It is best to steer clear of the initial 6.7 Powerstroke decades, which covered 2011 through 2014. The initial generation engine 6.7 Powerstroke motors had a number of problems, including the injector pump loss, leaks developing, and low bearing quality.

Broken valves for exhaust gases, faulty EGR coolers, troublesome EGT detectors, inadequate turbochargers, and defective EGT sensors are some other issues. Despite the fact that some of these problems were quickly fixed during manufacturing, others lasted for the whole first generation. I suggest putting in the second version.

How does the 6.7 Powerstroke Engine Perform in General?

The 6.7L diesel engine is now a great powerplant with 475 horsepower as well as 1050 Nm. How long will a 6.7 Power Stroke last? The 6.7L Power Stroke has demonstrated through years of manufacturing that it can easily surpass the 200,000-mile barrier as the “6.7 Powerstroke life expectancy” with minimal repairs.

Recirculation of exhaust gases (EGR)

The 6.7 liter motor has the unusual characteristic that the EGR flow is regulated through the EGR valve before reaching the EGR cooler.

Catalytic converter for diesel (DOC)

Hydrocarbons within the stream of the exhaust are to be oxidized by the ceramics catalytic converter known as the DOC.

Selective catalytic reduction (SCR)

Diesel exhaust liquid is combined with the exhaust flow and fed into the SCR.

Filter for diesel particulates (DPF)

The DPF catches diesel particulates and employs proactive regeneration innovation to regularly heat the exhaust structure, totally burning residue and cleaning the filter.

Which Specific Model Years of the 6.7 Powerstroke Should I be Cautious About?

The cars produced from 2011 to 2014 appear to have a lot of issues, making them the models you need to steer clear of the most. The 6.7L Power Stroke versions from 2011 to 2014 are additionally from an earlier era; the newer models until 2015 are considerably superior and hold up rather well.

The 6.7L Powerstroke motor comes in three versions; the first generation, which includes models from 2011 to 2014, is the most difficult to pick from and should be avoided. However, other customers don’t appear to experience any issues with their first-generation models of vehicles.

Almost all severe concerns regarding the 6.7 Powerstroke diesel engine that was produced from 2011 to 2014 concerning the first version of the motor. The first four years of manufacturing for this engine were, to put it mildly, disappointing, which is why we strongly advise against purchasing any Ford vehicle that includes an engine from the earliest edition of the 6.7 Powerstroke.

Are there any Common Problems Reported in the Early Years of the 6.7 Powerstroke?

The initial generation suffered from five main issues.

Coolant leaks in the radiator

Several 6.7 owners of older or earlier models observed that low coolant levels frequently happened. The main radiator of the Power Stroke engine, which contains two of them, was observed to be the least dependable.

Overheating was brought on by a faulty or blocked EGR cooler

The car’s engine may display the P0401 error number or appear to be overheated. The EGR coolers might be the issue in either case.

EGT Sensor Problems

There are four combustion air thermometers on the 6.7 Powerstroke. Every sensor may malfunction for a number of reasons. Even if it’s possible that only one will fail, it does happen that all four do.

Issues with the turbocharger

The 6.7L engine’s 2011–2014 iteration was fairly potent, having 390HP as well as 735 lb-ft truck torque. Ford chose a smaller turbocharger for the engine instead, though. When adding a turbocharger having so much power, you must take the horsepower of the engine into account. Ford neglected to.

Issues with the injection pump

Another issue that affected the owners of the original 6.7 Powerstroke was the injector pump breakdown. An injection pump made by Bosch, model CP4.2, is installed in these motors. However, this CP4 injector has been known to malfunction in both the 6.7 and 6.6L Duramax engines.

How Can I Prevent Problems in the 6.7 Powerstroke Engine?

Fluid leaks in the radiator

The OEM radiators may be upgraded for a dependable remedy.

Overheating is brought on by a faulty or clogged EGR filter

A fresh EGR cooler, priced at around $150, is the solution.

EGT Monitor Problems

The beneficial news is that Ford will cover the issue with an extended warranty, saving you from having to pay for pricey repairs. Changing the sensor alone might only provide a temporary fix.

Issues with the turbocharger

For the majority of folks who weren’t pushing their engines’ limits, things were OK. For individuals who performed, the harm done ranged from $1,000 to $2,000 in value.

Pumps Injection Issues

When metal debris comes into contact with the pumps, harm can range from a few thousand dollars to more than $750. This kind of damage may need the replacement of the complete fuel system. Repair prices are determined by a certified mechanic’s quotation, although the most severe case can exceed $10,000.

What are the Pros and Cons of Purchasing a Used Vehicle with the 6.7 Powerstroke?


Fuel efficiency is one of the main benefits of diesel engines. Diesel fuel provides 10 to 15% greater vitality than fuel, and one quart of diesel fuel can propel a car powered by diesel 20 to 35% farther than a gallon of petrol will.
