Best 6.7 Powerstroke CCV Kit: Reroute, Recirculating or Catch Can?

If you own a 2011 or newer 6.7L Powerstroke, the factory CCV system is one of the first things worth upgrading. There are three ways to fix it: a reroute kit, a recirculating system or a catch can. Here is how each one works, what it costs and which one we recommend for your truck.

What the 6.7 Powerstroke CCV Does

CCV stands for crankcase ventilation. Every diesel pushes some combustion gas past the piston rings into the crankcase. That gas is called blow by, and it has to go somewhere. On the 6.7 Powerstroke, Ford routes it through a filter box on top of the engine and back into the intake ahead of the turbo.

The problem is oil. Blow by carries oil mist, and the factory setup lets a lot of it back into the intake. Over time that oil coats the intake tract and turbo inlet, the factory CCV filter loads up, and crankcase pressure climbs. Higher crankcase pressure pushes oil past seals and gaskets, which is where a lot of 6.7 oil leaks start.

Option 1: CCV Reroute Kit

A reroute kit removes the factory CCV box and vents blow by out of the engine bay instead of into the intake. It is the simplest and cheapest fix, it frees up room on top of the engine and it keeps oil out of your intake for good.

• Powerhouse Diesel 6.7 Powerstroke CCV Reroute Kit: our billet aluminum kit, made in the USA, fits 2011 to 2026 F250 and F350 trucks, black or polished finish.
• SPE CCV Reroute Kit: venturi style design with no restrictive baffles.

The catch: venting crankcase gases to the atmosphere changes an emissions control system. Reroute kits are sold for off road and competition use only. If your truck has to stay emissions compliant or pass inspection, look at a recirculating system instead.

Option 2: Recirculating CCV System

A recirculating system replaces the factory CCV box with a better separator that pulls oil out of the blow by and returns it to the engine. The cleaned gas still goes back into the intake, so the system stays closed like the factory design. You get most of the benefit of a reroute without venting anything to the atmosphere.

• SPE Motorsports Recirculating CCV built for 2025 and newer 6.7L trucks
• SPE recirculating CCV to lower intake install kit for trucks running an aftermarket intake

SPE sells a separate recirculating kit for 2025 and newer trucks, so confirm your year on the listing before you order, or send us your VIN and we will match the right kit.

Option 3: Catch Can or Baffle Upgrade

If you want to keep the factory layout and spend less, a catch can or internal baffle traps more oil before it reaches the intake. It will not stop oil completely like a reroute, but it is a big step up from stock and it bolts right in.

• SPE CCV Internal Catch Can, 2011 to 2026 6.7L
• Smeding CCV Baffle Internal Catch Can, 2011 to 2020 6.7L
• SPE Motorsports External CCV Catch Can

Which 6.7 Powerstroke CCV Kit Is Best?

• Daily driver or tow rig that has to stay emissions compliant: a recirculating system. Clean intake, closed system, no drips.
• Off road or competition truck: a reroute kit. Cheapest, simplest and it gets oil out of the intake completely.
• Tight budget or a mostly stock truck: an internal catch can or baffle. Better than stock for the least money.

Running an aftermarket intake? Check that your CCV choice matches the intake. Some intake kits need a specific CCV connection or reroute to install. Browse intakes for 2011 to 2019 6.7 Powerstroke trucks and 2020 and newer trucks.

6.7 Powerstroke CCV FAQ

Is a CCV reroute the same as a CCV delete?

Mostly, yes. Both names describe removing the factory CCV box and venting blow by away from the intake. "Delete" is just the more common search term.

Will a CCV reroute drip oil?

A quality kit routes the vent tube low and away from hot parts, and you may see a small amount of oil at the tube over time. Keeping crankcase pressure healthy and oil at the right level keeps it minimal.

Do I need a catch can if I reroute?

Not usually. Some owners add one at the end of the vent tube to keep the frame and driveway clean.

Does a CCV upgrade add horsepower?

Not directly. The payoff is a cleaner intake and turbo, fewer oil leaks and more consistent performance over the life of the truck.
