Cummins CCV PCV Reroute Kit

6.7 Cummins CCV Delete & Reroute Kit | Filter Replacement & Delete Solution

A 6.7 Cummins CCV delete kit replaces the factory CCV filter arrangement and redirects crankcase vapor away from the original intake connection. This collection’s dedicated kit is listed for 2007.5–2024 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine.

Owners usually consider this modification after finding oily residue near the turbo inlet or intake piping, dealing with CCV filter maintenance, or wanting more room above the engine. The questions that matter before buying are fitment, vapor and oil control, diagnostic codes, hose routing and whether the truck has excessive blow-by that a reroute kit cannot repair.

Off-road use only: This product is intended only for lawful closed-course competition or off-road vehicles that are not registered or licensed for use on public roads. Removing or altering emissions-related equipment may violate the Clean Air Act and applicable state or local laws. Confirm the requirements for your vehicle before purchasing or installing.

Confirm Your 6.7 Cummins CCV Kit Fitment

Do not order by engine family alone. Confirm that your truck is a RAM 2500 or 3500 with a 6.7L Cummins and falls within the product’s listed 2007.5–2024 model-year range.

This listed fitment does not include 5.9L Cummins engines or non-RAM applications. Trucks with aftermarket valve covers, engine swaps or modified crankcase components require additional compatibility checks.

Problems Owners Are Trying to Solve

Oil Residue in the Turbo Inlet or Intake Piping

The factory closed crankcase ventilation system returns crankcase vapor to the intake. That vapor can carry oil mist, and owners commonly notice an oily film near the turbo inlet or inside the intake plumbing. A CCV reroute changes where that vapor travels, helping remove this source of oil mist from the original intake path.

A light film does not automatically mean the turbo has failed. At the same time, a reroute kit will not repair a leaking turbo seal, excessive blow-by or another mechanical source of oil consumption.

Recurring CCV Filter Maintenance

A factory-style replacement filter keeps the original closed system in place and remains a service item. A CCV filter delete removes that filter arrangement and uses a separate breather outlet. Buyers should decide whether eliminating the factory filter is worth the new inspection and routing considerations that come with an external breather.

Concern About Vapor, Odor and Oil Film

Redirecting crankcase vapor does not make blow-by disappear. Depending on engine condition and breather placement, an external reroute may make oil vapor, odor or residue more noticeable around the outlet. Owners with higher-mileage engines or heavy blow-by may see more vapor than a healthy engine.

This kit includes a breather filter but does not list a catch can. If containing collected oil is a priority, do not assume that a breather-only setup will behave like a catch-can system.

Fear of a Check-Engine Light

The product information notes that CCV-related diagnostic codes may appear on some vehicles after modification. Results can vary by model year, calibration and existing modifications. Do not assume that every 2007.5–2024 truck will respond in the same way, and do not purchase a tuner solely on the assumption that it is required.

CCV Delete vs. Factory CCV Filter Replacement

What the Cummins CCV Reroute Kit Includes

The 2007.5–2024 6.7L Cummins CCV PCV reroute kit lists the following components:

What to Check Before Ordering

• Fitment: Verify a 2007.5–2024 RAM 2500 or 3500 with the 6.7L Cummins diesel engine.
• Engine condition: Diagnose heavy vapor, rapid oil loss, excessive crankcase pressure or active leaks before treating a reroute kit as the repair.
• Desired configuration: Confirm that you want a breather-style reroute rather than a factory replacement filter or catch-can system.
• Diagnostic behavior: Check the requirements for your exact model year and calibration.
• Complete sealing: The original intake connection must be sealed correctly while the crankcase retains an unrestricted ventilation route.
• Hose placement: The hose must remain clear of hot, sharp and moving components and must not kink or trap fluid.
• Vapor management: Consider where oil vapor, odor and possible residue will exit before installation.
• Warranty and legality: Confirm how the modification affects warranty coverage and whether the vehicle is legally eligible.

What This Kit Will Not Fix

• Excessive blow-by caused by worn or damaged engine components
• A failed turbo seal or another source of oil entering the intake
• Oil leaks caused by excessive crankcase pressure or restricted ventilation
• Existing diagnostic, tuning or emissions-system faults
• Oil vapor and odor created by the engine itself

If a breather quickly becomes saturated, the truck pushes a large amount of oil from the outlet, or vapor increases sharply after installation, stop and diagnose the engine and routing. Do not assume that adding another filter or catch can will correct the underlying cause.

Installation and Inspection Priorities

Correct routing matters more than a fast installation. Follow the product-specific instructions, seal the original intake port properly and verify that the new vent path is open and secure. Restricting the crankcase outlet can increase pressure and contribute to oil leaks.

After installation, inspect the breather, hose, plug and clamps for oil contamination, loose connections, damaged hose or leakage. Also check whether vapor or odor is entering the cab or leaving residue on nearby components. If you cannot verify safe routing and crankcase ventilation, use a qualified diesel technician.

FAQ

Q: What years does this 6.7 Cummins CCV delete kit fit?

A: The dedicated kit is listed for 2007.5–2024 RAM 2500 and RAM 3500 trucks equipped with the 6.7L Cummins diesel engine. It is not listed for 5.9L Cummins or non-RAM applications.

Q: Will a CCV reroute stop oil from reaching the turbo inlet?

A: It redirects the factory CCV outlet away from the intake, removing that route as a source of oil mist. It will not prevent oil from entering the intake through a failed turbo seal or another mechanical problem.

Q: Is some oil vapor from the breather normal?

A: A reroute still has to release crankcase vapor. The amount of visible vapor or residue depends on engine condition, blow-by and routing. Heavy vapor or rapid oil accumulation should be diagnosed rather than treated as normal.

Q: Will the breather filter prevent oil smell and residue?

A: It can help manage the outlet, but it cannot eliminate the vapor produced by the engine. Some installations may still produce noticeable odor or an oily film near the discharge area.

Q: Does this kit include a catch can?

A: No catch can is listed. The kit includes one breather filter, one 90-degree vent hose, one billet plug and four clamps.

Q: Can a CCV delete cause a check-engine light?

A: The product information notes that CCV-related codes may appear on some vehicles. Results vary by model year, calibration and other modifications, so confirm the requirements for your truck before installation.

Q: Will a CCV delete fix excessive blow-by?

A: No. It changes where crankcase vapor is routed but does not repair worn rings, cylinder damage or another mechanical cause of excessive blow-by.

Q: Does the kit require maintenance?

A: Inspect the breather filter, hose, intake plug and clamps periodically. Service or replace contaminated or damaged components as needed for your operating conditions.

Q: Is a 6.7 Cummins CCV delete legal for street use?

A: It may not be. Altering emissions-related equipment can violate federal, state or local requirements when a vehicle is operated on public roads. This product is intended only for lawful off-road or closed-course competition applications.
