Crank Case Filter Ford 6.7: Top Problems, Non-Delete Fixes & CCV Delete Kits
Everything you need to know about your Ford 6.7L Powerstroke crankcase ventilation (CCV) system — from why the stock CCV filter keeps failing to the alternative reroute and delete kits.
The Ford 6.7L Powerstroke's stock crankcase ventilation system is prone to clogging, oil vapor blowback into the intake, and turbo sludge buildup. A quality CCV reroute/delete kit — starting at $69.99 from DPFexhaust — is an alternative solution to solve the problem by redirecting oil vapor away from your intake system.
Part 1: The 3 Biggest 6.7 Powerstroke Crankcase Ventilation Problems
Spend five minutes on any Ford diesel forum — Powerstroke.org, Ford Truck Enthusiasts, or the diesel Facebook groups — and you'll see the same three CCV complaints over and over. These aren't rare edge-case failures; they're a known weak spot that Ford has issued multiple Technical Service Bulletins (TSBs) to address.
"My 6.7 has 80k miles and I'm already on my second CCV filter. Every time it clogs, the boost drops and I get white smoke at idle. Dealer says it's 'normal wear.' $300 part, $200 labor, and it'll clog again in 30k miles. There has to be a better way."
"Pulled my intercooler to check a boost leak and found it coated in a thick film of oily sludge. Traced it all back to the CCV system dumping oil vapor straight into the intake. This stuff gets everywhere — intercooler, EGR cooler, intake manifold. Cleaning it out took hours."
"Check engine light came on with a boost pressure code. Mechanic found the CCV vent hose had collapsed from the negative pressure. Oil was being sucked back through the turbo — the bearings are toast. $4,000 turbo replacement on a truck with 95k miles."
Part 2: Non-Delete Fixes for 6.7 Powerstroke Crankcase Ventilation Problems
Several maintenance steps can extend the life of your stock crankcase ventilation system and reduce the frequency of problems. These fixes won't eliminate the root issue — oil vapor will always re-enter the intake on a closed-loop system — but they can buy time and protect your engine.
| Fix | What It Does | Estimated Cost |
|---|---|---|
| Replace CCV Filter on Schedule | Ford recommends replacing the CCV oil separator filter every 67,500 miles — but on trucks with heavy idling, every 30k–40k miles is safer. A fresh filter restores proper crankcase pressure. | $60–$150 (OEM) |
| Inspect & Replace CCV Hoses | Check the CCV vent hoses for cracks, collapse, or hardening at every oil change. Soft or kinked hoses cause pressure imbalances that accelerate filter clogging and can starve the turbo of clean oil. | $20–$80 |
| Shorten Idle Time | Extended idling produces more blow-by at low combustion temperatures, saturating the CCV filter faster. Where possible, reduce idle warm-up time — modern diesels warm up faster under light load than at idle. | Free |
| Add an Aftermarket Catch Can | An aftermarket catch can added to the existing CCV circuit traps oil droplets before they re-enter the intake. This doesn't reroute the system but significantly reduces oil vapor contamination of the intercooler and intake manifold. | $50–$150 |
| Clean the Intake Manifold | If oil vapor buildup is already present, a professional intake manifold cleaning removes sludge deposits and restores airflow. Combined with a CCV filter replacement, this is the best non-delete reset for high-mileage trucks. | $200–$500 |
Part 3: The Alternative Solution — 6.7 Powerstroke CCV Reroute/Delete Kits
A CCV reroute kit redirects crankcase blow-by gases away from your intake system and vents them externally — typically to the atmosphere or into a catch can that you can empty during oil changes. The results are: a clean intake tract, a protected turbo, and no more CCV filter replacement costs. DPFexhaust offers two purpose-built options for Ford 6.7L Powerstroke trucks.
CCV Reroute/Delete — 2011–2024 Ford F250/F350/F450/F550 6.7L Powerstroke
The standard CCV reroute kit for the 6.7L Powerstroke covers all 2011–2024 Super Duty trucks and is available in three configurations depending on how thoroughly you want to filter your blow-by gases:
- CCV Reroute Kit (Basic): $69.99–$89.00 — Redirects crankcase vapor away from the intake. Best for trucks on a budget or mild-use applications.
- CCV Reroute + Internal Catch Can: $129.00 — Adds an internal oil separator that traps oil droplets before venting, keeping your engine bay cleaner.
- CCV Reroute + Internal & External Catch Can: $278.00 — Full two-stage filtration. Best for high-mileage trucks or owners who want maximum oil separation.
✅ High-efficiency Venturi design — smooth airflow with no sharp bends to trap oil
✅ ¾" × 6 ft reinforced silicone hose — heat-resistant and pressure-tolerant
✅ Black anodized metal components — corrosion-resistant and durable
✅ DIY-friendly installation (~1–3 hours), PDF guide included
✅ Available in Black, Red, or Silver
Upgraded CCV Reroute — 2011–2025 Ford F250/F350/F450 6.7L Powerstroke
The upgraded kit extends coverage through 2025 model year trucks and introduces three key improvements over the standard version. Choose your filtration level based on how much oil separation you need:
- 90% Oil Molecule Removal: $109.00 — Significant improvement over stock. Ideal for daily drivers and trucks under 100k miles.
- 95% Oil Molecule Removal: $198.00 — High-efficiency separation for trucks with heavier blow-by or frequent towing.
- 100% Oil Molecule Removal: $379.00 — Maximum protection. Best for competition use, hard working trucks, or high-mileage engines.
✅ 360-degree rotatable elbow design — precisely adjust hose routing to fit your engine bay without forcing bends or kinking the hose
