What is the biggest problem with 6.7 Power Stroke?
The 6.7 Power Stroke engine, introduced by Ford in 2011, is a popular choice for heavy-duty trucks due to its impressive power and towing capabilities. However, like any engine, it has its share of challenges. In this article, we’ll explore the most significant issue associated with the 6.7 Power Stroke and provide insights into how to address it effectively.
Understanding the 6.7 Power Stroke Engine
The 6.7 Power Stroke is a turbocharged diesel engine designed for Ford’s Super Duty trucks. Known for its durability and performance, it features advanced technology such as a compacted graphite iron block and a reverse-flow layout. While it has earned a reputation for reliability, certain recurring issues have been reported by owners and mechanics alike.
The Biggest Problem: Turbocharger Failures
One of the most common and significant problems with the 6.7 Power Stroke engine is turbocharger failure. The turbocharger is a critical component that boosts engine performance by forcing more air into the combustion chamber. Unfortunately, in the 6.7 Power Stroke, this component has been prone to premature failure, especially in earlier models.
Why Does the Turbocharger Fail?
Turbocharger failures in the 6.7 Power Stroke can be attributed to several factors:
- Excessive Heat: The turbocharger operates under extreme heat and pressure, which can lead to wear and tear over time.
- Oil Contamination: Contaminated or insufficient oil can damage the turbocharger’s bearings, leading to failure.
- Design Limitations: Early models of the 6.7 Power Stroke used a single-sequential turbocharger design, which was more prone to stress and failure compared to later dual turbo designs.
Signs of a Failing Turbocharger
It’s essential to recognize the warning signs of a failing turbocharger to prevent further damage to your engine. Look out for the following symptoms:
- Loss of power or reduced acceleration.
- Excessive smoke from the exhaust, often black or blue in color.
- Unusual noises, such as whining or grinding, coming from the engine.
- Increased oil consumption or visible oil leaks near the turbocharger.
How to Address Turbocharger Issues
If you suspect turbocharger problems in your 6.7 Power Stroke, here are the steps you should take:
- Inspect and Maintain: Regularly inspect the turbocharger and ensure proper oil changes using high-quality oil to prevent contamination.
- Upgrade Components: Consider upgrading to a more robust aftermarket turbocharger if you frequently tow heavy loads or operate in extreme conditions.
- Seek Professional Help: If you notice any signs of failure, consult a trusted mechanic to diagnose and repair the issue promptly.

Frequently Asked Questions
What is the life expectancy of a 6.7 Power Stroke?
200,000 to 300,000 miles
How Long Will It Last? With proper care, many truck owners report that their deleted 6.7 Powerstroke engines last 200,000 to 300,000 miles or more. However, neglecting maintenance or using poor-quality delete kits can shorten the engine's lifespan.
What year does 6.7 have a bad turbo?
Turbocharger failures have been a frequent issue with the 2011 and 2012 model year 6.7L Powerstroke equipped pickups. The early-production Honeywell DualBoost turbo's Achilles' heel appeared to be its ceramic bearings. However, these reliability concerns were resolved with the switch to steel ball bearings.
What is the life expectancy of a 6.7 Power Stroke CP4?
between 200,000 and 300,000 miles
The Ford 6.7L Powerstroke diesel engine is known for its durability and can last between 200,000 and 300,000 miles on average. However, with consistent and proper maintenance, this engine can reach 400,000 miles or more, making it a reliable choice for many truck owners.
Does the 6.7 Power Stroke have problems?
Injection-Pump Fail
The injection pump is the Achilles heel for all 6.7L Power Stroke engines prior to 2020. The pump, a Bosch CP4. 2, is known for breaking down due to metal-on-metal contact that is promoted by air inside the pump.
What year of 6.7 Power Stroke to avoid?
Issues with the Ford 6.7-liter Power Stroke are most pronounced in the first generation (2011-2014), but some problems have transcended generations. The injection pump could be trouble in pre-2020 engines.
Which 6.7 Powerstroke to avoid?
While the second and third-generation 6.7-liter Power Stroke engines are considered to be the best, the first generation — model years 2011 to 2014 — is widely regarded as the worst.
How long do 6.7 Power Stroke turbos last?
Some owners of vehicles with Powerstroke engines report their turbochargers have lasted around 100,000–150,000 miles. A few have reached 200,000 miles or more before noticing a drop in power and performance. That's a pretty good run and usually well within expectations for most vehicles.
What is the life expectancy of a 6.7 powerstroke CP4?
between 200,000 and 300,000 miles
The Ford 6.7L Powerstroke diesel engine is known for its durability and can last between 200,000 and 300,000 miles on average. However, with consistent and proper maintenance, this engine can reach 400,000 miles or more, making it a reliable choice for many truck owners.
Is the 6.6 Duramax better than the 6.7 Power Stroke?
Here are some key points to consider: Power Output: Typically, the 6.6 Duramax delivers around 445 horsepower and 910 lb-ft of torque. The 6.7 Powerstroke offers around 450 horsepower and 1,050 lb-ft of torque. Towing Capacity: The Powerstroke engine has a slightly higher towing capacity.
Which 6.7 Power Stroke to avoid?
While the second and third-generation 6.7-liter Power Stroke engines are considered to be the best, the first generation — model years 2011 to 2014 — is widely regarded as the worst.
