The best 6.7 Power Stroke CCV delete kit is not automatically the one with the most hose, the largest can, or the boldest oil-capture claim. The right setup must keep crankcase pressure under control, separate oil without becoming a restriction, fit the exact Super Duty model year, and survive towing heat, winter condensate, vibration, and jobsite dirt. On a street-driven truck, road-use compliance belongs in that decision too.
One point needs to be clear from the start: crankcase ventilation cannot actually be deleted. Combustion gas that leaks past the piston rings still has to leave the crankcase. Most products sold as a "CCV delete" are really a reroute, a replacement separator, a catch-can system, or some combination of those parts.
What the 6.7L Power Stroke CCV System Actually Does
Every diesel has blow-by. A small amount of combustion gas passes the piston rings and enters the crankcase, carrying water vapor, fuel vapor, soot, and suspended oil droplets. The CCV system moves that gas out while controlling crankcase pressure. It also separates part of the oil so the engine does not push liquid through the vent path.
The factory 6.7L Power Stroke arrangement is closed-loop: separated vapor returns toward the intake instead of venting under the truck. That is why a light oil film can appear in the turbo inlet, charge-air boots, and intercooler plumbing. A film alone does not prove the separator has failed. Standing oil, rapidly increasing carryover, several new oil leaks, or measured crankcase pressure outside the Ford specification deserves a proper diagnosis.
For a plain-language explanation of blow-by, oil mist, and pressure control, read this guide to diesel crankcase ventilation operation.
What Makes One CCV Kit Better Than Another?
A serious buyer should judge the whole flow path, not just the machined cap. These seven checks matter on a Heavy-duty Ford that tows, carries Payload, idles on a Jobsite, or sees subzero starts.
| Design check | What a good kit should show | Why it matters |
|---|---|---|
| Flow capacity | Adequate fitting and hose inside diameter, smooth bends, and no small hidden outlet behind a large external fitting | A restrictive kit can raise crankcase pressure and load seals even when the outside hardware looks Heavy-duty. |
| Oil separation | Baffles, mesh, coalescing media, or another stated separation method with service access | A hollow cap redirects vapor but does little to stop oil droplets from coating the frame or filling a long hose. |
| Pressure control | A design that matches the engine's required ventilation strategy and does not rely on an unverified one-way valve | Too much restriction and uncontrolled suction can both create problems. |
| Oil handling | A continuous drain-back path or a catch can with a reachable drain and enough capacity for the truck's duty cycle | Collected oil and water need somewhere safe to go. "Maintenance-free" hardware still needs inspection. |
| Cold-weather behavior | No low hose trap, protected routing, and a separator that can be inspected for oil-water emulsion | Condensate can freeze and turn an open-looking hose into a restriction after an overnight cold soak. |
| Fitment | Separate early- and late-model variants where needed, correct seals and bolts, sensor provisions, and chassis clearance | 2011-2016, 2017-and-newer, pickup, and chassis-cab applications should not be treated as one identical layout. |
| Reversibility | Bolt-on installation, retained factory parts, and no unnecessary cutting or permanent wiring changes | A reversible Mod is easier to diagnose, service, sell, or return to stock. |
Model Year and Fitment Checks
The 6.7L Power Stroke has been used in Ford Super Duty trucks since 2011, but separator hardware, sensor strategy, chassis clearance, and service information have changed. Buy by VIN, installed component, and exact kit variant, not by the phrase "2011+" alone.
| Truck group | Fitment questions to answer | Common buying mistake |
|---|---|---|
| 2011-2016 F-250/F-350/F-450/F-550 | Confirm separator casting, valve-cover interface, hose direction, supplied block-off cap, and clearance around fuel-system hardware. | Ordering a 2017-and-newer hose or fitting package because the listing only says "6.7 Powerstroke." |
| 2017-2019 Super Duty | Check SRW versus DRW, pickup versus chassis cab, separator part number, and whether Ford TSB 19-2142 applies. | Assuming every truck has the same serviceable filter covered by the bulletin. |
| 2020-2024 Super Duty | Verify the current separator, connector and sensor provisions, hose clearance, and product-page year range. | Reusing an early-truck install video as the only Fitment reference. |
| 2025 models | Several current product pages warn that sensor retention or modification may be required. Get written confirmation for the exact VIN and variant. | Assuming a mechanical Bolt-on kit will be electronically transparent. |
| 2026 models | The three product pages compared below do not clearly list 2026 Fitment. Confirm with Ford service data and the seller before purchase. | Treating last year's fitment as automatic approval for a new model year. |
2016 F-350 Fuel Filter Housing Clearance
The closed-loop recirculating-kit page warns of possible minor interference with the fuel filter housing on some 2016 F-350 trucks. Treat that as a pre-install Fitment check, not a cosmetic footnote. Before tightening the separator, dry-fit the housing and hoses, confirm that the fuel-filter lid remains serviceable, and check clearance with the engine off while nearby components are cold. The CCV housing must not preload, rub, or block access to the fuel system. Do not grind a fuel-filter housing, force a hose into a kink, or stack unlisted spacers to make the kit sit down. If the supplied configuration does not clear, stop and get written fitment guidance or exchange it for the correct variant.
Ford TSB 19-2142 applies to a defined group of 2017-2019 F-Super Duty DRW pickups and chassis cabs, plus specified F-650/F-750 applications. It describes oil-consumption concerns after extended idle and replacement of a restricted filter-style separator. It does not say every 6.7L Power Stroke has the same filter or the same failure. Review Ford TSB 19-2142 hosted by NHTSA and then confirm current Ford service information by VIN.
Do These Checks Before Buying a Kit
A reroute can change where vapor and oil go. It cannot repair worn piston rings, reseal a damaged rear main seal, fix a turbo oil leak, or correct an overfilled crankcase. Build a baseline first.
- Check oil level correctly: Park level and follow the owner-manual procedure. Oil above the maximum mark can increase carryover and cause engine damage.
- Inspect the current CCV path: Look for a kinked hose, loose clamp, split connector, plugged fitting, collapsed liner, restricted separator, or blocked oil drain-back.
- Locate the oil source: Clean the turbo inlet and charge pipes, record mileage and duty cycle, then measure new accumulation. Check the turbo compressor and oil drain before blaming the CCV assembly.
- Measure crankcase pressure: Use a low-range differential manometer in inches of water column and the current Ford test procedure. A boost gauge is too coarse, and the loose oil-cap test is not a measurement.
- Evaluate engine condition: If pressure stays high with a verified open vent path, continue with cylinder contribution, relative compression, leak-down, or Ford-directed testing.
- Match the repair to the finding: Replace a failed factory part when that is the confirmed cause. Choose aftermarket hardware only when its flow, service, Fitment, and legal tradeoffs suit the truck.
If the main complaint is oil inside a charge-air boot, use a measured charge-air oil-source diagnostic process before ordering parts.
Closed-Loop, Open Reroute, or Catch Can?
| CCV strategy | Best match | Main benefit | Tradeoffs |
|---|---|---|---|
| Correct OEM separator | Stock daily driver, warranty-sensitive truck, fleet unit, or emissions-inspection area | Factory pressure control, winter validation, closed-loop routing, and known service documentation | Some oil film may still reach the intake, and service design varies by VIN. |
| Aftermarket closed-loop recirculating separator | Street truck whose owner wants serviceable oil separation without open venting | Returns vapor to the intake while adding accessible baffles or mesh | Media can restrict, drain-back can fail, and claimed flow capacity needs evidence. |
| Open filtered reroute | Narrow off-highway or competition use where local rules allow it and the owner accepts regular inspection | Keeps recirculated crankcase vapor out of the turbo inlet | Odor, visible vapor, oil residue, hose freezing, road contamination, and compliance concerns |
| External catch-can reroute | Owner who wants to measure collected liquid and can maintain the system | Makes oil-water collection visible and drainable | Requires a service interval; a full or frozen can can become a pressure restriction. |
| Rear-exit or exhaust-routed system | Off-highway build where cab odor and underbody residue are major concerns | Moves the outlet away from the engine bay and cab area | Long hose, heat, road debris, condensate traps, exhaust backpressure, and permanent exhaust changes require careful control. |
For most road-driven F-250 and F-350 trucks, start with the factory-correct separator or a closed-loop design. An open rear-exit setup is not automatically "better" just because the intake stays drier. The engine still needs stable pressure under hot Towing load and during a below-zero cold start.
What 2.0 and 3.0 Should Mean in Practical Terms
The original article described three generations: a basic hollow reroute, a 2.0 version with internal oil separation, and a 3.0 version that adds an external catch can. That progression makes mechanical sense, but generation numbers are seller naming, not an industry standard.
| Common version label | Typical hardware change | What the buyer should verify |
|---|---|---|
| Basic or 1.0 reroute | Replacement cap, fitting, and discharge hose with little or no oil-separation media | Actual internal flow area, hose routing, oil residue control, and safe outlet location |
| Filtered or 2.0 design | Internal baffle, mesh, or coalescing element intended to remove more suspended oil | Pressure drop when clean and oil-loaded, cleaning access, drain-back path, and cold-weather behavior |
| Dual-stage or 3.0 design | Internal separation plus an external catch can or second collection stage | Can volume, baffle design, drain access, mounting rigidity, hose slope, and a realistic service interval |
A listed "95%" or "100%" oil-capture figure is not enough by itself. Ask what aerosol size was tested, the vapor flow rate, oil loading, temperature, pressure drop, test duration, and whether the result came from a complete engine-duty cycle or a bench fixture. Without that information, treat the percentage as a product-page claim, not a universal field result.

Installation Details That Decide Whether the Kit Works
- Protect the hose: Keep it away from the exhaust manifold, DPF, steering shaft, driveshaft, front axle, suspension travel, and sharp frame edges.
- Avoid low traps: Maintain a steady route so oil and water do not pool in a sag. This matters during extreme weather and repeated short trips.
- Use the correct seal: Clean the valve-cover surface, seat the O-ring or gasket squarely, and do not use excess sealant that can enter a drain passage.
- Follow the supplied torque values: The public product pages do not publish one verified bolt-torque value for every variant. Use the current kit instructions and Ford service information, not a universal internet number.
- Retain sensors: Never defeat or leave a required sensor hanging just to make a broad-year kit fit.
- Make service possible: Mount an external can where it can be drained with the truck on the ground, even when a trailer or Jobsite body limits access.
- Test under real load: After installation, inspect warm crankcase pressure, leaks, hose collapse, stored codes, oil collection, odor, and clearance after a loaded drive, not just five minutes of driveway idle.
Do not borrow a rough torque range from a different CCV cap or model year. These kits use different plate thicknesses, fasteners, sealing methods, and valve-cover interfaces. Too much torque can distort a plate, cut an O-ring, or damage threads; too little can create a vapor or oil leak. If the current instructions do not provide a variant-specific value and tightening sequence, obtain them from the manufacturer before installation. Mark the fasteners after tightening and inspect them, the seal, and crankcase pressure again after the first loaded heat cycle.
Check an external catch can after the first 500-1,000 miles, then set the interval from measured collection. A high-mileage engine, long idle hours, repeated Towing, and cold short trips can fill it much faster than an unloaded highway truck. A drain-back separator does not need routine emptying, but its media, seals, hose, and drain passage still need inspection.
Real-World Owner Decisions
| Truck use | Priority | Practical choice | What can go wrong |
|---|---|---|---|
| F-250 daily driver | Low odor, clean installation, predictable service | Factory separator or verified closed-loop recirculating design | An open hose can put vapor smell near the cab at stoplights. |
| F-350 fifth-wheel tow rig | Stable pressure during sustained load and easy inspection | Low-restriction closed-loop separator or properly sized serviced catch-can system | A small saturated element may become restrictive when blow-by volume rises under load. |
| High-idle Jobsite truck | Condensate management and measurable service interval | Accessible separator or catch can with frequent early checks | Water-oil emulsion can accumulate and freeze in a can or low hose. |
| Off-roading or muddy access roads | Rigid mounting and protected outlet | Short, protected routing with filtration and no outlet near tires or brakes | Mud, water, or debris can block a poorly placed open filter or hose end. |
| High-mileage truck with heavy blow-by | Engine diagnosis before modification | Pressure and cylinder-condition testing first | A large catch can can hide oil carryover without fixing worn rings. |
Claims That Need Proof
- "Adds horsepower": A CCV kit is not a power adder by default. It may remove a measured restriction or reduce future oil contamination, but that is different from producing repeatable horsepower.
- "Captures 100% of oil": Ask for the test method, aerosol size range, flow rate, temperature, oil loading, pressure drop, and duration.
- "Maintenance-free": No drain can be an advantage, but every hose, seal, filter, drain-back path, and mounting point still needs inspection.
- "No odor": Outlet position and separation can reduce smell near the cab. Engine condition, wind direction, idle time, and routing still affect the result.
- "Fits all 2011+ trucks": A broad headline cannot replace exact variant, sensor, chassis, and model-year confirmation.
Warranty, Emissions, and Road-Use Limits
The EPA states that parts and practices that disable, bypass, or reduce the effectiveness of required emissions controls may constitute tampering or defeat devices. Review the EPA aftermarket tampering guidance. For an on-road work truck, the factory-correct closed-loop part is the lowest-risk default unless the replacement has a documented legal basis for that exact application.
An aftermarket part does not automatically erase the entire vehicle warranty. Damage linked to a restricted hose, failed seal, missing sensor, incorrect installation, or altered emissions configuration can still be excluded. Keep the stock parts, dated photos, instructions, receipts, crankcase-pressure readings, and maintenance records.

Frequently Asked Questions
Q: What is the best 6.7 Power Stroke CCV delete kit for a daily driver?
A: The conservative choice is the correct Ford separator or a properly sized closed-loop recirculating separator. It contains vapor, avoids an open outlet under the truck, and is easier to defend for an on-road application. Confirm the exact model year, chassis, sensor strategy, and local rules.
Q: Will a CCV reroute fix excessive blow-by?
A: No. A reroute can reduce restriction or change where oil vapor travels, but it cannot repair worn rings, a damaged cylinder, or another mechanical source of excessive blow-by. Measure crankcase pressure and test engine condition first.
Q: Does every 6.7L Power Stroke need a CCV filter every 30,000 to 50,000 miles?
A: No. Separator design and service requirements vary by year, chassis, and installed assembly. Ford TSB 19-2142 applies to a defined set of trucks, not every 6.7L. Use VIN-specific Ford owner and service information.
Q: Does a 6.7 Power Stroke CCV delete add horsepower?
A: Not by itself. A healthy factory system is designed to ventilate the crankcase without becoming a major airflow restriction. Treat horsepower claims as unproven unless the seller supplies repeatable before-and-after data with crankcase pressure and test conditions.
Q: Does a mechanical CCV reroute require tuning?
A: Many early mechanical kits do not change fuel, boost, or timing calibration. Later trucks may have sensor or monitoring provisions that must be retained. Confirm the exact VIN and kit instructions before assuming no electronic work is needed.
Q: How often should I drain an external catch can?
A: Check it after the first 500-1,000 miles and record the amount. Then set an interval from the truck's actual collection rate. Winter short trips, long idle hours, heavy Towing, and engine wear can shorten that interval sharply.
Q: Can I use a 2011-2025 kit on a 2026 Super Duty?
A: Do not assume that it fits. The compared pages do not clearly list 2026 compatibility. Confirm valve-cover interface, sensors, hoses, chassis clearance, instructions, and written seller Fitment for the exact VIN.
