What is the life expectancy of a 6.7 powerstroke CP4?
The life expectancy of a 6.7 Powerstroke CP4 fuel injection pump can vary significantly depending on several factors. In general, these fuel pumps are known to have a relatively short lifespan compared to other components in a diesel engine system.
What is a 6.7 Powerstroke CP4?
The 6.7 Powerstroke is a diesel engine produced by Ford for their heavy-duty pickup trucks and vans. The CP4 is the fuel injection pump used in these engines, responsible for delivering high-pressure fuel to the engine's injectors. This type of fuel pump is known for its complex design and sensitivity to contaminants in the fuel system.
Factors Affecting CP4 Life Expectancy
Several factors can impact the lifespan of a 6.7 Powerstroke CP4 fuel pump:
- Fuel Quality: Poor-quality fuel, including fuel with high levels of contaminants or water, can quickly wear down the internal components of the CP4 pump.
- Maintenance History: Regular maintenance, such as fuel filter changes and fuel system cleanings, can help extend the life of the CP4 pump.
- Driving Conditions: Vehicles used for heavy-duty towing or hauling, or those operated in extreme temperatures, may experience accelerated wear on the CP4 pump.
- Manufacturing Defects: Some CP4 pumps have been known to fail prematurely due to manufacturing defects or design flaws.
Given these factors, the average life expectancy of a 6.7 Powerstroke CP4 fuel pump is typically between 60,000 to 150,000 miles, with many failing well before the higher end of that range. However, some owners have reported their CP4 pumps lasting much longer with proper maintenance and fuel quality.
Addressing CP4 Pump Failures
When a 6.7 Powerstroke CP4 fuel pump fails, it can cause significant damage to the engine and fuel system. The most common solution is to replace the CP4 pump with a more reliable alternative, such as a CP3 pump conversion. This modification can help prevent future failures and extend the life of the engine.
In summary, the life expectancy of a 6.7 Powerstroke CP4 fuel pump can vary widely, but it is generally considered a weak point in the engine's design. Proper maintenance, fuel quality, and modifications can help extend the pump's lifespan and protect the engine from costly failures.
What year 6.7 Power Stroke to stay away from?
2011-2014
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.
How many miles should a 6.7 Power Stroke last?
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 is the biggest problem with 6.7 Power Stroke?
What are the most common problems with the 6.7 Powerstroke?
- Cold Side Charge Pipe Failure. The cold side charge pipe is a critical component that carries compressed air from the turbocharger to the intake manifold.
- CP4 Injection Pump Failure.
- Turbo Issues.
- Fuel Filter Housing Failure.
How to tell if your CP4 is going bad?
Difficult Starting: Difficulty initiating the engine, particularly when cold, may signal CP4 pump failure, resulting in inadequate fuel pressure to the injectors. Engine Misfires: Inconsistent fuel delivery due to CP4 pump failure can lead to engine misfires, rough idling, or hesitation during acceleration.
How many miles will a CP4 pump last?
Air in the pump means that metal rubs against metal, causing accelerated wear. This will eventually cause the CP4 to fail, often around 100,000 miles. Before it fails, metal shavings are produced by the CP4, which travel into the fuel injectors and the fuel lines with catastrophic results.
What year do Fords have CP4 problems?
The issue affects models from 2011 onward. Plaintiffs argue that Ford was aware of the defect but failed to take proper action, leaving truck owners with expensive repair costs. The lawsuit primarily targets Ford trucks with 6.7L Power Stroke diesel engines, particularly those from model years 2011 and later.
What is the life expectancy of a 6.7 Power Stroke engine?
200,000 miles
Life Expectancy and Reliability
The 6.7L Power Stroke is built for longevity – Many owners report reaching well over 200,000 miles with proper maintenance. Regular servicing, especially for components like the turbocharger, exhaust systems, and fuel injectors, can extend the engine's lifespan even further.
What year does 6.7 have a bad turbo?
These turbo chargers are prone to bearing failure on the '11 and '12 models.
How many miles is too many for a used 6.7 Power Stroke?
We sell tons of 6.7s and you are definitely making the right decision. In terms of mileage, something with 100k or more is no concern. We see them come through with well over 200k and no major issues at all. For diesel trucks, mileage is not the concern - it's maintenance.
How do you prevent CP4 failure on a 6.7 Power Stroke?
Preventive Measures
- Replace the problematic CP4 with a failure-proof DCR pump.
- Install a CP4 Bypass “Disaster Prevention Kit”
- Install an Exergy Fuel System Saver.
- Running OEM Motocraft Filters.
- Run fuel additives.
