I've had my 2015 F-250 for about five years now, and overall, it's been a solid truck. The 6.7L Powerstroke has plenty of power, the fuel economy is respectable for a heavy truck, and it's been reliable through a lot of miles. But like anyone who pays attention to their truck, I've noticed things over time.
Nothing major. Just little observations. A bit of oil residue around the intake connections. A slightly slower turbo spool than I remembered from when the truck was newer. A nagging thought in the back of my mind about what was accumulating inside my intercooler.
I started reading up on the 6.7L platform and kept running into discussions about the CCV system. Some guys ignored it. Some installed catch cans. Some went with full reroute kits. The more I read, the more I realized this was one of those things that doesn't cause immediate failure but slowly, quietly affects performance over time.
After looking at options, I ended up installing a CCV reroute kit on my truck. Here's what I learned about why this matters and what actually changes.
How it works: The factory system routes those gases through a separator in the valve cover, then back into the intake stream to be reburned. It's a closed system designed to meet emissions requirements.
The problem: That separator isn't 100% effective. It catches some oil, but a lot of oil vapor still makes it into the intake. That oil mist travels through your turbo, through your intercooler, through your intake pipes, and eventually into your engine.
What that means: Every mile you drive, a fine oil mist is coating the inside of your intake system. It doesn't happen overnight, but over tens of thousands of miles, it adds up.
Oily residue: Every time I had the intake pipes off for something, I'd see oil inside them. Not huge puddles, but a definite film. That oil came from somewhere, and that somewhere was the CCV system.
Intercooler questions: I started wondering how much oil was sitting in the bottom of my intercooler. The intercooler is the lowest point in the intake system, so oil naturally drains down and collects there. An intercooler full of oil doesn't cool air as effectively.
Turbo spool: The truck still ran fine, but I couldn't help wondering if a cleaner intake tract would let the turbo spool a little quicker. Less oil coating everything means smoother airflow.
The long-term thought: I plan to keep this truck for a while. The idea of oil gradually building up in my intercooler and intake for another 100,000 miles didn't appeal to me.
The Venturi system: This particular kit uses a Venturi design. Without getting too technical, the Venturi effect uses the flow of air to create suction, which helps pull gases out of the crankcase more effectively than the factory system. Better evacuation means less pressure building up in the engine.
No more oil in the intake: This is the main event. With the CCV gases going elsewhere, your intake tract stays clean. No oil mist coating your pipes, no oil collecting in your intercooler, no oil getting sucked into your turbo.
Service-free operation: The kit is designed to be maintenance-free. Once it's installed, there's nothing to empty, nothing to clean, nothing to replace. It just works.
Cleaner engine bay: The factory CCV plumbing takes up space. Removing it opens up room in the engine bay, which is nice if you're doing other modifications.
Better combustion: The product notes that the engine gets "the cleanest oil residue-free air ensuring the strongest combustion." That's accurate. Oil in the intake doesn't help combustion—it just burns and leaves deposits.
No more oily pipes: The most obvious change is that my intake pipes stay dry. No more wiping oil off connections every time I have them apart. They look clean inside.
Intercooler stays clean: Without oil being continuously fed into the intake, the intercooler stays dry inside. That means it can do its job—cooling air—without a layer of oil insulating everything.
Crankcase pressure is managed: The Venturi system does a good job of keeping crankcase pressure in check. Less pressure means less stress on seals and gaskets over the long term.
Engine bay looks cleaner: The factory CCV stuff is gone, replaced by clean lines and aluminum components. It's not a performance thing, but it looks better.
Peace of mind: Knowing that I'm not slowly coating my intercooler in oil is worth something. It's one less thing to worry about.
Catch cans need emptying: You have to remember to drain them. If you forget, they fill up and stop working, or worse, become a restriction.
Catch cans can freeze: In cold weather, the collected oil and water mixture can freeze, blocking the system.
Catch cans add complexity: More hoses, more connections, more potential leak points.
This reroute kit is different. There's nothing to empty, nothing to freeze, nothing to maintain. Once it's installed, you forget about it.
What's involved: You remove the factory CCV components and install the new piping. The kit includes everything needed—no extra trips to the auto parts store.
The time: Figure a couple hours at a relaxed pace. Most of that time is getting the factory stuff off and routing the new lines cleanly.
The fitment: The kit is designed for 2011-2023 trucks, including cab and chassis models. Everything lines up as it should.
No special tools: Just basic hand tools—sockets, wrenches, maybe a pick for hose clamps.
Aluminum construction: The main components are machined aluminum, not plastic. They'll last indefinitely and won't crack or degrade over time.
Black anodized finish: Anodizing adds a hard, corrosion-resistant layer. It also looks good under the hood.
Quality hoses: The included hoses are designed for the application—oil-resistant, heat-resistant, and flexible enough to route easily.
The TruckTok CCV Reroute Kit fixes that. It sends those crankcase gases elsewhere, keeping your intake tract clean and dry. The Venturi design ensures good crankcase evacuation without the maintenance of a catch can.
What you get:
For anyone planning to keep their 6.7L long-term, this is one of those modifications that just makes sense. It's not about horsepower—it's about preventing the slow, quiet degradation that happens over hundreds of thousands of miles.

After looking at options, I ended up installing a CCV reroute kit on my truck. Here's what I learned about why this matters and what actually changes.
Part 1: What the Factory CCV System Actually Does
The crankcase ventilation system on the 6.7L has a straightforward job. It needs to evacuate pressure from the crankcase that builds up from blow-by—those combustion gases that sneak past the piston rings.How it works: The factory system routes those gases through a separator in the valve cover, then back into the intake stream to be reburned. It's a closed system designed to meet emissions requirements.
The problem: That separator isn't 100% effective. It catches some oil, but a lot of oil vapor still makes it into the intake. That oil mist travels through your turbo, through your intercooler, through your intake pipes, and eventually into your engine.
What that means: Every mile you drive, a fine oil mist is coating the inside of your intake system. It doesn't happen overnight, but over tens of thousands of miles, it adds up.
Part 2: What I Started Noticing Over Time
After putting some miles on my truck, a few things became apparent.Oily residue: Every time I had the intake pipes off for something, I'd see oil inside them. Not huge puddles, but a definite film. That oil came from somewhere, and that somewhere was the CCV system.
Intercooler questions: I started wondering how much oil was sitting in the bottom of my intercooler. The intercooler is the lowest point in the intake system, so oil naturally drains down and collects there. An intercooler full of oil doesn't cool air as effectively.

The long-term thought: I plan to keep this truck for a while. The idea of oil gradually building up in my intercooler and intake for another 100,000 miles didn't appeal to me.
Part 3: What a CCV Reroute Actually Does
A CCV reroute kit changes where those crankcase gases go. Instead of sending them back into your intake, it routes them somewhere else—usually down toward the ground or through a filter.The Venturi system: This particular kit uses a Venturi design. Without getting too technical, the Venturi effect uses the flow of air to create suction, which helps pull gases out of the crankcase more effectively than the factory system. Better evacuation means less pressure building up in the engine.
No more oil in the intake: This is the main event. With the CCV gases going elsewhere, your intake tract stays clean. No oil mist coating your pipes, no oil collecting in your intercooler, no oil getting sucked into your turbo.

Better combustion: The product notes that the engine gets "the cleanest oil residue-free air ensuring the strongest combustion." That's accurate. Oil in the intake doesn't help combustion—it just burns and leaves deposits.
Part 4: What You Gain by Installing One
After running this setup for a while, several things became clear.No more oily pipes: The most obvious change is that my intake pipes stay dry. No more wiping oil off connections every time I have them apart. They look clean inside.
Intercooler stays clean: Without oil being continuously fed into the intake, the intercooler stays dry inside. That means it can do its job—cooling air—without a layer of oil insulating everything.
Crankcase pressure is managed: The Venturi system does a good job of keeping crankcase pressure in check. Less pressure means less stress on seals and gaskets over the long term.
Engine bay looks cleaner: The factory CCV stuff is gone, replaced by clean lines and aluminum components. It's not a performance thing, but it looks better.
Peace of mind: Knowing that I'm not slowly coating my intercooler in oil is worth something. It's one less thing to worry about.
Part 5: How It's Different from a Catch Can
A lot of guys run catch cans on their trucks. Those work, but they have some downsides.Catch cans need emptying: You have to remember to drain them. If you forget, they fill up and stop working, or worse, become a restriction.
Catch cans can freeze: In cold weather, the collected oil and water mixture can freeze, blocking the system.
Catch cans add complexity: More hoses, more connections, more potential leak points.
This reroute kit is different. There's nothing to empty, nothing to freeze, nothing to maintain. Once it's installed, you forget about it.
Part 6: The Installation Reality
Installing the kit is straightforward for someone with basic mechanical skills.What's involved: You remove the factory CCV components and install the new piping. The kit includes everything needed—no extra trips to the auto parts store.
The time: Figure a couple hours at a relaxed pace. Most of that time is getting the factory stuff off and routing the new lines cleanly.
The fitment: The kit is designed for 2011-2023 trucks, including cab and chassis models. Everything lines up as it should.
No special tools: Just basic hand tools—sockets, wrenches, maybe a pick for hose clamps.
Part 7: The Materials Matter
The kit uses aluminum components with black anodized finish and rubber hoses where needed.Aluminum construction: The main components are machined aluminum, not plastic. They'll last indefinitely and won't crack or degrade over time.
Black anodized finish: Anodizing adds a hard, corrosion-resistant layer. It also looks good under the hood.
Quality hoses: The included hoses are designed for the application—oil-resistant, heat-resistant, and flexible enough to route easily.
Part 8: The Verdict
The 2011-2023 6.7L Powerstroke is a solid engine, but its factory CCV system has a built-in compromise. It routes oil vapor back into your intake, where it slowly coats everything in a fine film. Over time, that oil builds up in your intercooler, in your intake pipes, and on your turbo blades.The TruckTok CCV Reroute Kit fixes that. It sends those crankcase gases elsewhere, keeping your intake tract clean and dry. The Venturi design ensures good crankcase evacuation without the maintenance of a catch can.
What you get:
- No more oil in your intake pipes
- A clean intercooler that actually cools air
- Managed crankcase pressure
- A cleaner engine bay
- Zero maintenance once installed
For anyone planning to keep their 6.7L long-term, this is one of those modifications that just makes sense. It's not about horsepower—it's about preventing the slow, quiet degradation that happens over hundreds of thousands of miles.
