6.7 CCV Reroute Kit: Complete Buying Guide

A 6.7 CCV reroute kit changes how crankcase vapors travel through a diesel engine. Depending on the design, the kit may route vapor away from the intake, pass it through a catch can, or replace parts of the factory crankcase ventilation system.

The right kit depends on your engine, model year, desired oil control, maintenance preference, and local regulations. This guide compares the main options for 6.7L Powerstroke and 6.7L Cummins trucks.

What Does a CCV Reroute Kit Do?

CCV means closed crankcase ventilation. During normal operation, a small amount of combustion gas passes the piston rings and enters the crankcase. This is known as blow-by.

The factory CCV system manages this pressure and separates some oil from the vapor before routing the gas through the intake system. A reroute kit changes that path.

A properly selected kit may help:

• Reduce oil mist in the intake

• Keep charge pipes cleaner

• Control crankcase vapor

• Simplify CCV routing

• Add an oil catch can

• Replace worn hoses or fittings

A reroute kit cannot repair excessive engine blow-by, worn piston rings, failed turbo seals, or an overfilled crankcase.

Quick Product Comparison

Product contents can change. Check the current product photos and included-parts list before ordering.

Powerstroke vs. Cummins Fitment

“6.7L” does not describe one universal engine. Ford Powerstroke and Ram Cummins systems use different engines, valve covers, hose connections, brackets, and breather layouts.

A Powerstroke kit will not fit a Cummins engine. Never choose a kit by displacement alone.

Before buying, confirm:

• Model year

• Engine family

• Pickup or cab-and-chassis

• Stock or modified intake

• Factory CCV layout

• Hose connection size

• Available mounting space

Mid-year production changes may affect brackets, connectors, and hose routing. When uncertain, compare the product photos with the parts currently installed on the truck.

Basic Reroute or Catch Can?

Basic Reroute Kit

A basic kit usually includes an adapter or block-off component, hose, clamps, and installation hardware.

Choose it when you want:

• Fewer components

• Simple installation

• Lower initial cost

• Minimal maintenance

An open-ended hose may produce oil odor, visible vapor, or small amounts of residue. The hose must terminate away from the cab intake, exhaust, brakes, tires, belts, and moving suspension parts.

Reroute Kit With Catch Can

A catch can separates oil droplets from crankcase vapor before the vapor exits or returns to the intake.

Choose it when you want:

• Better oil control

• Less residue under the truck

• Cleaner hose routing

• A more complete system

Some catch cans require periodic draining. Other designs use internal separation or oil-return features. Follow the instructions for the exact product instead of assuming it is maintenance-free.

Upgrade Kit

An upgraded kit may add reinforced hose, improved sealing surfaces, billet components, stronger hardware, or revised routing.

Choose it when:

• The truck works in high heat

• The stock hose is deteriorated

• The engine has other modifications

• Long-term durability matters

• You want a catch can later

“Upgrade” does not automatically mean universal fitment. Confirm what is different from the basic version before paying more.

What Should the Kit Include?

Inspect the package before disassembling the truck. Missing seals, clamps, or fittings can stop the installation.

Hose Quality Matters

CCV vapor contains oil mist and moisture, while the hose operates in a hot engine compartment. A suitable hose should resist:

• Engine oil

• Heat

• Vacuum collapse

• Kinking

• Abrasion

• Weather exposure

Avoid thin general-purpose tubing. A hose that softens, collapses, or splits may create a restriction or oil leak.

Catch Can Features to Compare

Not every catch can performs the same way.

Look for:

• Internal baffling

• Secure fittings

• Drain access

• Serviceable design

• Strong bracket

• Adequate capacity

• Heat-safe seals

A hollow container with an inlet and outlet may offer limited oil separation. Internal baffles or separation media give oil droplets more opportunity to leave the vapor stream.

Installation Planning

Most installations require basic hand tools, but access and routing vary by truck.

A typical process includes:

1. Let the engine cool.

2. Remove the factory CCV parts.

3. Clean the sealing surfaces.

4. Install the adapter and seals.

5. Route the hose safely.

6. Mount the catch can, if included.

7. Tighten all clamps.

8. Check for leaks and restrictions.

Do not route a CCV hose:

• Against the exhaust

• Near a steering shaft

• Below the frame

• Toward the cab air intake

• Beside a tire

• Through a suspension path

Maintain smooth bends. A kinked or blocked hose can raise crankcase pressure and cause oil leaks.

Post-Installation Checks

After installation, verify:

• Stable idle

• No oil leaks

• No loose fittings

• No collapsed hose

• No unusual whistle

• No warning lights

• Safe hose clearance

Inspect the system again after the first heat cycle and after several days of driving. Heat and vibration can loosen a clamp or expose a routing problem.

If the system has a catch can, establish a regular inspection schedule. Cold weather and short trips can increase moisture inside the container.

Possible Drawbacks

A 6.7 CCV reroute kit may introduce tradeoffs:

• Oil or vapor odor

• Catch-can maintenance

• Moisture accumulation

• Hose freezing in severe cold

• Oil residue under the truck

• Warranty questions

• Inspection concerns

Open-to-atmosphere systems may not comply with emissions rules in every location. Confirm street-use legality and warranty implications before modifying the factory system.

What a CCV Kit Will Not Fix

Do not use a reroute kit to hide a mechanical problem. Diagnose the engine first if it has:

• Heavy continuous blow-by

• Rapid oil consumption

• Blue exhaust smoke

• Repeated seal failures

• Low compression

• Excessive crankcase pressure

These symptoms may indicate worn engine components, a turbocharger problem, blocked ventilation, incorrect oil level, or another fault requiring repair.

Factory Service or Reroute?

Replacing the factory filter or separator keeps the original closed-loop design. A reroute changes that design and may reduce oil entering the intake, depending on the kit.

Choose factory service when:

• The truck is under warranty

• Original compliance matters

• The engine is stock

• You want factory operation

Consider a reroute when:

• The exact kit fits the truck

• You understand the maintenance

• Local rules permit the change

• Oil control is the main goal

Use the truck’s current owner or service manual to determine whether its factory CCV element is replaceable, serviceable, or maintenance-free.

Frequently Asked Questions

Does a 6.7 CCV reroute kit add horsepower?

It is not normally a direct power modification. Its primary purpose is managing crankcase vapor and reducing oil contamination in the intake.

Does a CCV reroute require tuning?

Many kits are mechanical and may not require tuning. However, the answer depends on the truck, product design, sensors, and other modifications. Follow the product instructions.

Is a catch can necessary?

Not always. It is useful when controlling collected oil and residue is more important than choosing the simplest possible system.

Will a reroute stop all oil in the intake?

Not necessarily. Oil can also come from turbo seals, previous residue, overfilling, or other engine problems.

Can a catch can freeze?

Moisture can collect and freeze in cold climates. Inspect the can and hoses more frequently during winter.

Can I clean the factory CCV filter?

Follow the vehicle manufacturer’s instructions. Some factory filter elements are replacement items and should not be cleaned or reconditioned.

Will the truck smell after installation?

An open-vent design may produce crankcase odor. Correctly routing the hose away from the cab intake can reduce, but may not eliminate, the smell.

How often should I inspect the system?

Check it after installation, after the first heat cycle, at every oil change, and more frequently in severe cold or heavy-duty use.

Final Buying Checklist

Before ordering, confirm:

• Correct 6.7L engine

• Exact model year

• Complete hardware

• Hose material

• Catch-can type

• Drain access

• Mounting space

• Local compliance

• Warranty impact

The best 6.7 CCV reroute kit is not simply the most expensive option. Choose the kit that matches the engine, includes the required hardware, provides safe hose routing, and fits your preferred maintenance schedule.
