Mark is an experienced trailer transport operator who drives a 2015 F-350 with the 6.7L Powerstroke. One cold morning, he smelled a strong odor of oil from under the hood. A few hours later, he noticed oil spots on the ground. The diagnosis? A front main seal failure caused by excessive crankcase pressure—and the root cause was a clogged CCV filter.
The repair cost him over $2,000. What frustrated him most wasn’t the money—it was knowing that all of this could’ve been prevented with a simple upgrade: installing a CCV delete kit before the damage happened.
The Crankcase Ventilation System (CCV): A Hidden Risk Most Owners Overlook
The CCV system (Crankcase Ventilation System) in the 6.7L Powerstroke engine is designed to route crankcase gases back into the intake to be burned again. This helps manage emissions and regulate internal pressure. It sounds efficient, but there’s a downside: those gases are full of oil mist and fine contaminants.
If the CCV filter gets clogged, pressure builds rapidly in the crankcase. This can lead to seal failure, oil leaks, or worse.
While the OEM recommends replacing the CCV filter every 67,500 miles, real-world experience shows many filters start to clog as early as 30,000 miles. Since it’s hidden under the valve cover and not monitored electronically, most owners don’t realize there’s a problem—until the damage is already done.
SPELAB’s Three-Layered Solution to the CCV Problem
Designed with deep insights into the problems 6.7 Powerstroke owners face, the SPELAB CCV Delete Kit for Ford Powerstroke delivers a triple-layered solution that addresses oil seal failure, intake contamination, and pressure buildup at the source:
Full Reroute Design:
This kit completely bypasses the OEM CCV return line, eliminating blow-by oil vapor from re-entering the intake manifold or intercooler—reducing carbon buildup and oil pooling that degrade performance.
High-Efficiency Catch Can:
The included oil separator captures droplets efficiently, with a bottom drain valve for periodic disposal—preventing oil smells, engine bay grime, or underbody drips.
Active Pressure Release Architecture:
SPELAB’s engineered airflow pathway relieves crankcase pressure effectively, helping protect seals like the front main and timing cover gasket from failure.
Why SPELAB Uses an Angled Hose Design—And Why It Matters
Unlike many kits that use vertical or 90-degree hose routing, SPELAB’s design uses an angled upward route for a few very practical reasons:
Prevents oil backflow – The upward angle helps oil mist and condensation flow away from the engine, keeping the system clear and dry.
Improves airflow – Smooth hose routing minimizes turbulence and reduces the chance of oil vapor clinging to the inside of the hoses.
Avoids interference – The route is engineered to clear major components like the fuel filter, intake tubing, and wiring harnesses—making installation easier and more secure.
This design isn’t just cleaner—it’s smarter.
Oil Mist: The Silent Killer of Turbochargers and Engine Longevity
Many truck owners install a CCV delete simply to keep their intake piping cleaner, but the true value goes far beyond aesthetics. For your 6.7L Powerstroke, SPELAB’s CCV Delete Kit plays a direct role in extending the lifespan of both your turbocharger and engine.
When oil mist is routed back into the intake via the OEM CCV system, it coats the intercooler, intake manifold, and turbo blades with residue. This sticky film traps dirt and carbon particles from the air, causing:
-
Reduced airflow efficiency
-
Increased turbo lag or surging
-
Premature turbo wear due to carbon buildup on blades
Worse yet, residual oil enters the combustion chamber, leading to incomplete combustion, oil contamination, and accelerated wear of piston rings—compromising compression and lubrication over time.
With SPELAB’s CCV Delete Kit for 6.7L Powerstroke, the oil mist is fully rerouted and separated into a dedicated catch can system, keeping your intake clean and your turbo safe. This isn’t just a bolt-on—it’s a strategic upgrade to preserve the long-term health and performance of your engine.

FAQ
Q1. Will this void my warranty?
It depends on your dealer. Some may flag it as an emissions-related mod. If under warranty, ask first; if not, you're good to go.
Q2. Does it reduce EGR soot?
Yes, indirectly. Less oil mist means less sticky buildup inside EGR parts, so they stay cleaner longer.
Q3. How often should I drain the catch can?
Every 3,000–5,000 miles is ideal. Drain more often in cold weather, heavy towing, or idling conditions.
Q4. Is this kit safe for stock (untuned) trucks?
Yes. It works with stock engines, no tuning needed, and fully compatible with factory EGR.
Q5. Is it hard to install?
Not at all. Basic hand tools are enough. No cutting or tuning required. Most installs take under an hour.
