The best choice for a 6.7L crankcase filter delete depends on the truck: a ventilation reroute kit or catch can may suit some Ford Power Stroke owners, while Cummins owners may need a replacement filter or ventilation cover instead. These products are not interchangeable. Confirm the engine, model year, and local emissions rules before changing the crankcase ventilation system; rerouting or deleting factory equipment may be restricted for road use.

Engine Ventilation Kit CCV PCV Reroute
This kit is described as a replacement for the factory crankcase ventilation system and is intended to reroute crankcase vapors. The listing names F-650 and F-750 6.7L models and F-250 through F-550 Super Duty trucks. It says the reroute is intended to help prevent oil and sludge buildup.
Best for: Buyers with a listed Ford application who specifically want a crankcase ventilation reroute rather than a replacement filter. It is the most direct match here for a search about a 6.7L filter delete.
Caution: The supplied fitment details do not give model-year ranges. Confirm exact fitment and check emissions requirements before removing or changing factory ventilation equipment.
Mishimoto Baffled Oil Catch Can
This catch can is listed as a direct fit for 2011–2016 Ford 6.7L Power Stroke trucks. Its high-flow design lets the crankcase breathe while filtering oil, fuel, and water vapors. A 3 mm steel bracket is described as positioning the can for accessible servicing.
Best for: Owners seeking vapor filtration while retaining a breathing path, rather than a simple filter delete. Choose this if your truck falls within the stated year range and you prefer a serviceable catch-can setup.
Caution: The listing does not establish compatibility outside 2011–2016. A catch can is not the same product as a full ventilation reroute kit.
T487-D13637 Cummins Crankcase Filter
This is a replacement filter kit, not a delete or reroute. The listing specifies Dodge 2500 and 3500 6.7L applications from 2007.5 through 2018 and references Cummins 6.7L fitment. It includes a filter element, hose, bracket, and clamps. The stated multilayer construction is intended to capture dirt and help maintain system operation.
Best for: Cummins owners who need a filter replacement and want to keep a filtered crankcase system in place. It is a better option than a delete when the goal is to restore filtration.
Caution: The listing’s broad compatibility wording should be checked against the truck’s exact year and configuration before ordering.
Dodge Ram Crankcase Ventilation Cover
This ventilation cover is listed for Dodge Ram 2500 and 3500 models from 2007–2010, Dodge Ram 4500 and 5500 models from 2008–2010, and Ram 2500 through 5500 models for 2011. The provided information identifies it as a cover, not a complete filter-delete kit or reroute assembly.
Best for: Buyers replacing a crankcase ventilation cover on one of the listed truck applications. It may be relevant to a repair, but the listing does not describe a filter element or a complete delete solution.
Caution: The fitment description is specific to model years and series; confirm the exact application before purchase.
CP4 Disaster Prevention Bypass Kit
This listing describes a fuel-system protection kit for 2011–2026 Ford F-250 through F-550 6.7L Power Stroke trucks. The package details include a fuel filter and head, hoses, bracket, installation manual, and accessories. Its stated purpose is to help protect fuel-system components from CP4 pump debris.
Best for: A buyer researching CP4 fuel-system protection, not crankcase ventilation. It is included to clarify a common parts-search mismatch, but it is not a crankcase filter, delete, catch can, or reroute kit.
Caution: Do not choose this product to replace or modify a crankcase ventilation system.
Buying Guide: Choosing A 6.7L Crankcase Solution
Do you need a delete, reroute, catch can, or replacement filter?
These terms describe different approaches. A replacement filter keeps filtration in the system. A catch can collects some vapors and requires servicing. A reroute changes the vapor path. A delete removes or bypasses factory equipment. Match the part to the actual repair or modification you intend to make rather than relying on the word “delete” alone.
How do engine and model year affect fitment?
“6.7L” can refer to different engines, including Ford Power Stroke and Cummins applications. Check the make, model, year, engine, and part number against the product’s stated fitment. Do not assume that a Ford ventilation kit fits a Dodge or Ram truck, or that a listed year range applies to every trim.
What should you check before changing the system?
- Confirm the exact engine and vehicle year.
- Determine whether the part is a replacement filter, cover, catch can, or reroute kit.
- Review installation requirements and service needs from the product documentation.
- Check applicable federal, state, and local emissions rules before altering factory equipment.
Frequently Asked Questions
Is a crankcase filter delete the same as a catch can?
No. A delete removes or bypasses factory filtration, while a catch can is designed to collect vapors or contaminants. Product designs and installation requirements differ.
Will a Ford 6.7L reroute kit fit a Cummins 6.7L?
Do not assume so. The listed reroute kit names Ford applications, while the replacement filter listing names Dodge and Cummins applications. Verify fitment for the specific truck.
Is the T487-D13637 kit a delete kit?
No. It is described as a replacement crankcase filter kit for listed Dodge 6.7L applications.
Does the CP4 bypass kit modify crankcase ventilation?
No. Its listed purpose is fuel-system protection from CP4 debris, not crankcase filtration or ventilation.
Can a crankcase ventilation system be modified on a road vehicle?
Rules depend on the vehicle and location. Check applicable emissions requirements before removing or changing factory crankcase ventilation equipment.
