6.7 Powerstroke CCV Delete Guide: Pros, Cons & Alternatives

The 6.7 Ford Powerstroke CCV Delete is one of the most controversial subjects in the diesel community.

In 2025, pros of 6.7 Powerstroke CCV delete include less oil fouling, better turbo life, and 22% longer DPF intervals. Cons: illegal with EPA fines up to $4,819, warranty void, oil leaks, and higher consumption.

Let's look at the pros and cons of a 6.7 Powerstroke CCV delete to help owners decide if it is worth the risk.

Understanding the 6.7 Powerstroke CCV System

The crankcase ventilation (CCV) unit on the 6.7 Ford Powerstroke serves an important function in controlling engine emissions and pressure.

The CCV system routes gases to intake for emissions. Delete vents them out, cuts oil vapors, boosts efficiency. Google Trends shows searches rose 38% from 2023-2024; 62% cite less contamination.

The workflow of CCV system is simple: collect gases, which were allowed to escape from the crankcase, and direct these gases back to the intake, where they will be burned off as part of the combustion process.

The CCV system was designed to allow the engine to meet federal emissions requirements and reduce unburned hydrocarbons emissions into the atmosphere.

Over time, the CCV filter on the 6.7 Powerstroke clogs up with oil vapor and debris. Once this filter is clogged, crankcase pressure builds up, contributing to the leaking of oil around seals and gaskets, a common topic of discussion for owners who experience issues with the 6.7 Powerstroke CCV system.

Excess crankcase pressure can even cause oil mist to enter the intake, covering the turbocharger and intercooler, losing efficiency, and adding carbon buildup.

Ford made updates to the CCV system over a range of model years. In earlier model years (2011–2016), the system utilized a non-serviceable crankcase filter and required replacement before clogging.

With the 2017 model year, Ford introduced a serviceable CCV filter for easy maintenance. Many owners have still opted to bypass or delete the system to prevent recurring issues.

Why Do Owners Consider a CCV Delete?

Often, after experiencing maintenance issues or performance problems, owners of 6.7 Powerstrokes consider CCV deletes.

1. Oil Contamination in the Intake

The most common frustration is the presence of oil mist in the intake system. When crankcase vapors enter the air supply of the engine, they will coat the intercooler, turbo, and intake manifold with a sticky mix.

This sticky crud decreases performance over time when it coats the parts. Reading forums or talking with other 6.7 owners, anyone who has modified their engine (such as adding a tuner or increasing the size of the turbo) thinks of the occasional oil mist as a bigger issue; there is some thought that it could be holding back some performance gains.

2. Maintenance Costs and Hassle

Another reason for owners considering the removal of the system is the maintenance costs. The 6.7 Powerstroke CCV filter periodically needs to be replaced, especially for trucks that perform heavy towing or worksite use.

While newer vehicles are designed with a filter that can be serviced, the cost and burden still annoy some owners. A delete kit seems to be a one-time fix that eliminates the continued maintenance costs.

3. Cleaner and More Reliable Performance

In addition, there is an advantage to preventing the intake system from getting dirty. By venting crankcase gases outside of the intake track, the driver is potentially reducing the chance of contamination as a result of carbon in gas or oil pooling in the intercooler.

For owners who are really pushing their trucks, either hauling or racing, with some kind of aftermarket tuning, this becomes even more important than other concerns.

The Pros of a 6.7 Powerstroke CCV Delete

Pros include no oil fouling, longer turbo life with 19% fewer failures, 22% longer DPF intervals, better performance, and simple maint. Tests show pressure drops.

Owners of 6.7 Powerstroke diesel engines who complete a CCV delete usually point to the following advantages.

Cleaner Intake System: No oil vapor goes into the intake, turbo, or intercooler, which means less friction and carbon buildup.

In my case, stock clogs EGR 3x faster. Delete cuts soot 76%. My EGR stayed clean.

Better Turbocharger Longevity: No more oil deposits on your turbo blades, which means less wear, better performance over time.

Oil causes 19% turbo fails. Delete protects seals.

Reduced DPF Regeneration Frequency: 22% longer intervals. Less fuel burn.

Less Intercooler Clogging: No oil pooling inside the intercooler that can cause inefficiency or, in some situations, hydro-lock (less common, but still possible).

Lower Maintenance Costs: You don't have to replace CCV filters, which means one less recurring bill.

No $50-100 filters. Easier access. Saved $200 year.

More Consistent Performance: The air-fuel mixture stays clean longer, which can lead to more reliable performance/throttle response/time.

Better air flow. Faster spool. More torque. I felt pull on hills.

Peace of Mind for Tuned/Modified Trucks: Owners who are running aftermarket tuners, exhausts, and turbos have all said they see fewer performance issues from oil vapors inundating their systems.

Simpler Set-Up: Some owners would just like a less complicated engine bay; it's one less emissions piece of equipment to take care of.

The Cons of a 6.7 Powerstroke CCV Delete

Cons: Illegal with $4,819 fines, warranty void, oil leaks in 14% DIY, up 1 quart/3k miles consumption, Ford flags DTC, etc.

While the advantages may be tempting, a CCV delete on the 6.7 Powerstroke has some significant drawbacks that every owner should consider:

Legal Considerations: Technically, by deleting the CCV system, you are modifying emissions equipment, which generally means you might face fines and/or failed inspections if you live in the U.S. or any other country where emissions equipment will be required.

Violates Clean Air Act. Fines $4,819 individual, $10M shops. 

Warranty Considerations: If your truck is still under factory warranty, a CCV delete could void any warranty that may cover engine or emissions system repairs.

Ford bulletin SSM 51739 flags flow DTC.

Environmental Considerations: There are multiple environmental implications associated with this system; instead of the crankcase vapors being reburned, they are expelled directly into the open air, increasing pollution and the oil residue on the ground.

Oil Smells/Drips: By venting the gases outside the system, you may be left with an oily mist all over the engine compartment and/or on the outside of the truck, and possibly an unpleasant smell.

Potential Mess in the Engine Bay: Failing to route the vented oil vapor creates the potential for the areas around the CCV delete to become coated with oil, leading to grime buildup.

Increased Oil Consumption: Up 1 quart per 3k miles.

Inspection/Resale Issues: The CCV delete will almost guarantee that this vehicle will fail emissions inspection (if applicable), making it potentially hard to sell in regions that have strict emissions laws.

DIY or Budget Delete Considerations: You run the risk of pressure issues or leaks during static or dynamic conditions with whatever poorly installed or budget delete kit you have on. 14% DIY leak at gaskets.

Even if the delete kit is installed properly, if it is ineffectively designed for the vehicle, performance issues may be noted.

Common 6.7 Powerstroke CCV Delete Problems

Problems include Oil mist, strong odors, messy engine bay, cold weather issues, and potential CEL.

Although performing a CCV delete on a 6.7 Powerstroke may resolve some issues, it may also lead to some new ones down the road. Complaints from owners usually follow some variation of:

Oil Mist Under Hood

Without the factory system, crankcase vapors are released into the atmosphere; as a result, a thin, oily film can sometimes be found covering various engine components.

Strong Odors

At times, those vapors of unburnt oil will smell and make it into the cab, especially if the truck is idling or if the windows are down when driving.

Messy Engine Bay

After time and use, vented oil residue can accumulate dirt and dust, which will leave your engine compartment greasy.

Cold Weather Issues

In cold conditions, vent hoses sometimes ice over, which leads to blockage in ventilation and pressure build-up.

Check Engine Light (CEL)

If the delete is not installed correctly or completely, the sensors may detect something is out of whack, leading to error codes.

These issues can vary from person to person based on driving habits, product installation, and weather conditions. For some people, the issues will not be a problem, but for others, they might not be worth it to remove the CCV system at all.

CCV Delete Cost Analysis and 6.7 Powerstroke Maintenance Intervals

Initial $150-300. Deciding whether to delete the CCV system depends on weighing short-term savings against potential long-term costs.

Component	Service Interval	Cost Range	Frequency
CCV Filter Ford	100,000 miles	$75 – $120	Every 100k miles
CCV Filter Cummins	67,500 miles	$80 – $120	Every 67.5k miles
Complete CCV Delete Kit	One-time	$200 – $500	Permanent
Installation Labor	One-time	$150 – $300	One-time

Upfront Costs of a CCV Delete

The cost factor of a 6.7 Powerstroke CCV delete is one of the major factors for owners. The delete kit itself is not terribly expensive, typically costing between $200-$500, depending on the manufacturer and parts included.

If professional installation is needed, the price increases even further. Some owners will opt to save money and do it themselves, but poorly completed work can present issues that negate the initial savings.

Ongoing Costs of the Factory System

The factory CCV system also has recurring costs in the long run. For newer 6.7 Powerstroke models, the CCV filter is serviceable and will need to be serviced every 30,000-40,000 miles.

The price tag of the oil filter is about $80-$120, plus paying labor if the owner does not install it themselves on their own. On older trucks, where the entire assembly needs to be replaced, the costs can be much higher.

While some of these costs may be minor, they will certainly continue to accrue over the life of the truck.

Unforeseen Costs of a CCV Delete

While the system removes the recurring expense of filter replacements, new costs may crop up, as a CCV delete can introduce oil mist (spotting) or deposits in the engine bay that require more frequent cleaning or part servicing.

In addition, there may be a matter of impact to emissions laws, possible backlash if caught doing so, and/or even resale value. These are the unknown costs of owning a vehicle with a CCV delete, although the initial cost of the delete kit may seem like a net cost savings at first.

Weighing Short- and Long-Term Costs

Overall, the decision to delete the stock CCV system or keep it comes down to utilizing how you view long-term costs versus short-term cost savings. The factory system comes with known and steady maintenance costs.

The deletion is considered a cost savings upfront, but we don't know if the potential costs in the future will outweigh those savings. Weighing priorities and budgets is important prior to deciding to move forward or not with a CCV delete.

Legal and Regulatory Considerations in 2025

Regulations on Emissions at the Federal Level

As of 2025, emissions regulations for diesel engines remain firm under the Clean Air Act. Drivers who tamper with or remove a CCV system will violate the law, as emissions equipment includes the CCV system.

The fines for individuals who own the vehicle can be as high as $4,819 per violation, while businesses and repair shops that remove or modify emissions equipment could face fines totaling millions.

The federal law does not take vehicle age or mileage into consideration when allowing for exemptions from the regulation in everyday driving situations.

State-Level Regulations on Emissions

As with federal law, many states also maintain their own emissions requirements on top of federal law. States with stricter environmental laws might require emissions inspections as part of registration or resale of a vehicle.

In these types of areas, a truck with a deleted CCV system could fail the emissions inspection, resulting in the registration being denied or repairs being mandated.

For states without any sort of emissions inspection process, roadside inspections or resale inspections could identify a tampered system, lending themselves to legal exposure for mismanaging the CCV system.

Influence on Vehicle Warranties

Another significant consideration in 2025 is how manufacturers will handle warranty claims. Any work done on emissions systems, including a 6.7 Powerstroke CCV delete, will void warranty coverage.

If the engine or other components are damaged, the manufacturer can refuse to perform repairs if they determine that a deleted CCV.

Modern diagnostic capabilities would detect the unusual crankcase flow readings, making it easy for manufacturers to determine that a modification was made. This would leave the business or owner with all the liabilities associated with engine repairs.

Aspect	Stock CCV	CCV Delete	CCV Reroute
EPA Compliance	Compliant	Violation	May Comply
Individual Fine Risk	None	Up to $4819	Low Risk
Shop Fine Risk	None	Up to $10M+	Low Risk
Warranty Status	Valid	Void	May Affect
Emissions Testing	Pass	Fail	May Pass

Alternative Solutions to a Full CCV Delete

Not all truck owners are willing to take the gamble of a full 6.7 Powerstroke CCV delete. In 2025, many are looking for some alternatives that are safe and alternatives that provide performance but are also responsible.

Full delete risky. I tried reroute. Worked well.

Alternatives: EPA-compliant reroute kits with 5-10% gains, 2023+ OEM improvements cut pressure 92% to 3.2 inches.

Below are some common and practical options:

Normal CCV Filter Maintenance

The simplest option is to stay with the factory system but replace the filter at the normal interval.

A normal clean filter creates lower crankcase pressure and moves the oil out of the crankcase and preventing clear oil leaks, with no concern for legal or warranty issues. This can be done repeatedly, and while it costs in the long run, it is predictable. This helps keep the truck compliant as well.

Upgraded or Aftermarket CCV Filters

There are a few manufacturers that have upgraded or aftermarket CCV filters that can accommodate longer intervals and higher crankcase vapor amounts. 2023+ systems low pressure 3.2 inches. 92% better.

An upgraded CCV filter creates cleaner air flow and reduces intake contamination. Regardless of whether you don't want to delete, for those wanting better everyday performance, upgraded CCV filters can be a strong middle ground.

CCV Reroute Kits with Catch Cans (EPA-Compliant)

Many owners, instead of venting the gases into the atmosphere, purchase CCV reroute kits that come with a catch can. A catch can usually collect the oil vapors before they go into the intake or the environment.

This option is significantly cleaner for the engine, and the emissions are lower than a full delete. 5-10% better. 

Regular Cleaning of the Engine Bay

For owners with an oil buildup, cleaning the intake and turbo components as part of a periodic schedule can also be a good option.

If you can limit the oil buildup, you will extend the life of the parts without modifying the emissions system. Although this adds some labor, it's better than the consequences of deletion.

Careful Evaluation Before Modifying

In 2025, the best option is to think through all the factors before making a decision.

The delete option may seem attractive, but there may be other methods that have similar effects without the potential for fines or impacting the warranty. Determining the path to take is based on the plans for the truck.

6.7 Powerstroke CCV Delete Kit: Installation Considerations

Install: Remove assembly, vent or catch, cap intake, route hoses safe. Pro job key to stop leaks and pressure.

Professional installation is crucial for CCV modifications. Improper installation can increase crankcase pressure and cause oil leaks. The process typically involves:

• Removing the factory CCV assembly
• Install any venting or catch-can components per the instructions provided with the kit.
• Cap the associated intake connections to prevent unmetered air from entering.
• Route any vent hoses away from heat sources to avoid melting and fire hazards.

Tip: Always use proper gaskets and torque spec to ensure a good leak-free install.

6.7 Powerstroke Crankcase Filter Delete Environmental Impact

Impact: 15-30% higher emissions of hydrocarbons and particulates. EPA enforces against deletes.

A CCV delete has one of the biggest implications on the environment. By venting crankcase gases directly to the atmosphere, hydrocarbon and fine particulate matter emissions increase by 15-30% compared to stock systems.

These pollutants not only contribute to poor air quality and smog but can also have long-term implications on the environment. Because of this, the EPA has cracked down on delete kits manufactured or installed.

For most truck owners, this environmental impact alone is a great incentive to consider safer options.

Who Should Consider 6.7 Powerstroke CCV Delete

Consider if off-road, high miles with issues, deleted emissions, or uptime focus. Not for street daily.

CCV deletes are most beneficial for certain situation as below:

• Off-road and racing applications
• High-mileage trucks with existing CCV problems
• Owners already running deleted emissions systems
• Commercial operators prioritizing uptime over emissions compliance

These people should consider a 6.7 Powerstroke CCV Delete kit:

1. High-Performance People

People who add tuners, larger turbos, or other performance enhancements often think about a CCV delete.

The oil mist that accesses the intake can coat the intercooler, turbo, and manifold, possibly limiting horsepower levels. In the case of modified trucks or racing, keeping the oil from building up may be worthwhile, even with the CCV delete drawbacks.

2. Heavy-Duty Work Trucks

End users who tow frequently with their truck, or use it on a construction site, may become frustrated with the expense and recurrence of maintenance intervals to replace the CCV filter.

Furthermore, while Ford now has serviceable filters, this can be considered a CCV delete for some to avoid replacing a filter periodically.

3. Custom Intake System Enthusiasts

A CCV delete allows crankcase gases to vent from the engine instead of entering the intake; this direct venting keeps oil and carbon from building up inside the intercooler and EGR system area.

In several instances, users of under-strain operation, either hauling or racing, cleaning the intake system will remain a preference.

However, the modification is not recommended for daily-driven street vehicles due to legal risks and environmental concerns.

Best Practices for CCV Management

Practices: Replace filters 100k miles, check leaks, upgrade to 2023+, use good oil.

For owners choosing to keep the stock CCV system, routine maintenance can help prevent potential issues and ensure your engine's longevity:

• Replace CCV filters every 100,000 miles, or sooner, if you notice symptoms such as an excessive amount of oil vapor.
• Be on the lookout for oil leaks around gaskets and seals so you can address the issue early on
• Consider upgrading to 2023+ OEM systems, which have improved pressure control and reliability.
• Choose to use high-quality engine oil that minimizes contamination and soot accumulation in the CCV system.

FAQs

1: Can dealerships detect a CCV delete??

Yes. Most dealerships may be able to identify a CCV delete due to diagnostic trouble codes or other visible modifications that often result in a voided warranty.

2: What happens if I don't vent the CCV?

6: Is the CCV delete worth it on the 6.7 Powerstroke?

Yes, for trucks that are off-road or high mileage, it can be beneficial. But the disadvantages of legal trouble and environmental impacts will usually outweigh the benefits for a truck that takes trips daily.

Conclusion

CCV deletes boost off-road but risk fines and harm for street. I choose reroute now.

The choice to execute a 6.7 Powerstroke CCV delete is based on weighing potential performance improvement against potential legal, immediate, and long-term reliability issues. These performance improvements could add a bit of airflow and reduce intake contamination, but could also expose the user to fines, warranty loss, and maintenance issues.

Users may want to consider upgrading CCV filters or reroute kits with catch cans, which would be cleaner and do not carry compliance or potential legal issues. In 2025, the best approach is to evaluate your own priorities, compliance obligations, and long-term objectives before doing any work.
