6.0L Power Stroke FAQ
Frequently Asked Questions about the 6.0L Power Stroke
The International built 6.0L Power Stroke is often regarded as the lemon of the diesel industry. Though it's true that many problems were associated with these engines, the problems have been glorified. Furthermore, most of the issues can be directly related to how the engines are treated (driving habits, maintenance neglect, etc). Understanding the problems, behavior, and nature of the 6.0L Power Stroke is important for owners who want to enjoy the performance and reliability of their hard working 6.0L for hundreds of thousands of miles.
Is the 6.0L Power Stroke a Bad Engine?
The 6.0L is not a bad engine. Quite the opposite, the performance that the 6.0L achieves with its relatively small size is impressive. The engine is sufficiently strong and reliable at its intended power levels. The problems associated with the 6.0L have very little to do with the engine itself, but rather the design of the emissions components. Properly maintained, the 6.0L provides reliability, performance, and fuel economy.
Should I avoid the 6.0L Power Stroke?
If you want a diesel that can run flawlessly without proper maintenance at the recommended intervals, then the 6.0L is probally not for you. The 6.0L Power Stroke is very sensitive to neglect, and owners who extend the service intervals of their engine are the most likely to experience problems. If you are prepared to stay current on the engines maintenance, there is no reason to avoid the 6.0L Power Stroke. If you are in the market to "hot rod" your diesel, the 6.0L can be adequately equipped to handle massive performance levels with a set of performance head studs and an upgraded EGR system.
Why was the 6.0L Power Stroke Phased out?
The 6.0L Power Stroke was replaced with the 6.4L due to increased emissions regulations. The 6.4L is able to meet stricter emissions for several reasons, including:
- Diesel particulate filter to capture particulate matter.
- High pressure common rail injection for increased combustion efficiency.
- Upgraded and adequately sized EGR system, not prone to failure like 6.0L EGR components.
The 6.4L was able to exceed emissions regulations and stay competitive with the performance of Cummins and Duramax engines.
What are the Advantages of the 6.0L Power Stroke?
- Impressive fuel economy. 16-18 mpg combined and 19-20 mpg highway mileage are not uncommon.
- VGT provides quick turbo spool times for off-idle performance.
- Torque output is steady over a broad power range, making 6.0L equipped trucks great tow rigs and work trucks.
What are the Disadvantages of the 6.0L Power Stroke?
- Sensitive to neglect. Injection system is sensitive to water contamination and poor fuel quality.
- EGR cooler/valve clogging due to soot build up can occur and cause engine problems.
- TTY head bolts do not provide adequate clamping force for diesels with increased power output (head studs can remedy this).
- Many engines repairs require the cab to be removed (although Ford has designed the Super Duty so that this is not as complex as it may seem).
Where is the serial number located on the 6.0L Power Stroke?
The serial number is located on the left rear corner of the crank case. It should start with a 6.0. The last 7 digits represent the sequential build number of the engine.
