Complete Guide to Your ford f150 oil separator catch can Installation
Modern direct-injection systems are highly efficient but suffer from a severe mechanical vulnerability.
Fuel no longer washes over the intake valves, leading to massive oil residue accumulation.
Installing a specialized ford f150 oil catch can completely resolves this engineering oversight by cleaning the Positive Crankcase Ventilation (PCV) path.
The system works by intercepting dirty crankcase vapors before they reach your intake manifold.
Choose a standard single-valve setup or go with a ford f150 oil catch can dual valve system for maximum protection.
A highly engineered ford f150 baffled oil catch can uses internal condensation plates to separate heavy oil droplets from air.
This prevents performance loss and keeps your combustion chambers running cleanly.
Many truck owners feel deeply frustrated by expensive dealership maintenance costs that are easily avoided with simple afternoon projects.
Completing this upgrade yourself provides the immense satisfaction of protecting your expensive truck with your own hands.
Required Tools and Equipment
Before you begin, gather a basic 10mm socket, a flathead screwdriver, and some shop towels.
The entire installation process typically takes less than thirty minutes in a home garage.
Step-by-Step Installation Process
-
Locate and Disconnect the Factory PCV Hose
Pop your truck hood and locate the passenger side PCV valve near the rear of the valve cover.
Gently press the plastic release tabs on the factory quick-connect fittings.
Carefully pull the line away from the engine to avoid snapping fragile plastic parts.
Keep a clean shop towel handy to catch any small drips of motor oil.
-
Secure the Mounting Bracket to the Engine Bay
Locate the factory mounting bolt near the passenger side firewall.
Remove the bolt using your 10mm socket wrench.
Position the heavy-duty bracket that came with your aftermarket kit over the hole.
Reinstall the bolt securely but do not overtighten and strip the threads.
-
Attach and Route the New Catch Can Hoses
Connect the clean inlet hose to the factory PCV port on your valve cover.
Route the hose neatly to the designated inlet fitting on your new separator canister.
Attach the second outlet hose to the intake manifold port.
Ensure the quick-connect fittings click firmly into place to avoid vacuum leaks.
-
Final System Inspection and Alignment
Check that all hoses are routed safely away from hot engine components.
Tighten the canister body onto the mounting bracket until it is completely snug.
Double-check that the bottom drain valve is fully closed.
Start your engine and check for any vacuum leaks.

Why Your EcoBoost Engine Needs a ford f150 oil separator
Turbocharged EcoBoost engines are highly susceptible to severe intake valve carbon deposit buildup.
Because fuel is sprayed directly into the combustion chamber, it never cleans the back of the intake valves.
Over time, sticky oil vapors from the crankcase bake onto these hot metal surfaces.
This causes a restrictive layer of carbon that chokes engine airflow and drops fuel economy.
You might start experiencing rough idling, engine misfires, or sluggish throttle response during acceleration.
According to certified ASE mechanics, installing a catch can prevents this sludge from reaching your intake.
Many members on the popular F150Forum community report catching several ounces of oil every thousand miles.
Using the correct ford f150 engine oil weights is vital for minimizing initial blow-by.
Consult our detailed ford f150 engine oil weights guide to ensure you fill your crankcase with the proper fluid.
Will Installing an oil separator f150 Void Your Factory Warranty?
Many truck owners worry that simple DIY upgrades will instantly void their factory warranty coverage.
Fortunately, the federal Magnuson-Moss Warranty Act protects consumers from unfair warranty denials.
A dealership cannot deny a warranty claim unless they prove the aftermarket part caused the failure.
Because an oil separator simply cleans the PCV air path, it is highly unlikely to cause engine damage.
However, we always recommend keeping your factory PCV hoses in your garage.
If you need to take your truck in for repairs, you can swap the stock lines back on.
This provides absolute peace of mind when dealing with dealership service advisors.
Always follow the recommended guidelines in the ford f150 engine oil viscosity guide to keep your warranty fully intact.
Comparing EcoBoost and Coyote V8 Requirements
The requirements for a ford f150 oil separator vary significantly between engine designs.
The 5.0L Coyote V8 engine uses both port and direct fuel injection in newer models.
This dual-injection system naturally washes the intake valves with gasoline, reducing carbon buildup.
However, the Coyote engine still produces a high volume of oil mist at high engine speeds.
An oil separator keeps the intake plenum dry and prevents oil from lowering your effective fuel octane.
For EcoBoost engines, a separator is mandatory to prevent long-term performance degradation.
Make sure you verify your engine displacement when purchasing your kit components.
Consulting the official ford f150 engine oil weight specs ensures your oil retains its protective qualities.
How to Maintain Your oil separator f150 for Peak Performance
An oil separator is not a set-it-and-forget-it modification.
You must establish a regular maintenance routine to empty the captured contaminants before they overflow.
During the warm summer months, you should check the canister level every three thousand miles.
Cold winter weather requires much more frequent attention due to rapid condensation buildup.
Water vapor mixes with oil blow-by to create a milky mixture that fills the can quickly.
If this mixture freezes inside the can, it blocks your PCV system entirely.
A blocked PCV system can blow out seals, leaving you with costly, heartbreaking oil leaks.
| Driving Condition | Emptying Interval | What to Expect |
|---|---|---|
| Warm Summer Driving | Every 3,000 miles | Thick, dark motor oil residue |
| Freezing Winter Driving | Every 1,000 miles | Milky water and oil mixture |
| Heavy Towing & Hauling | Every 1,500 miles | Increased volume of oil blow-by |
Crucial Mistakes to Avoid During Your ford f150 oil separator Install
Installing an aftermarket kit is straightforward, but simple errors can trigger dashboard warning lights.
The most common mistake is installing the inline check valves backwards.
This completely blocks the PCV airflow, causing high crankcase pressure that destroys gaskets.
Always verify the directional flow arrow on the valve points toward the engine intake manifold.
Another major error is using cheap, non-reinforced vacuum hoses from local auto stores.
These low-grade hoses will collapse under the intense vacuum of your turbochargers.
Only use the high-quality, reinforced hoses supplied with your specialized kit.
A loose fitting creates a vacuum leak that will trigger an annoying Check Engine light on your dashboard.
Frequently Asked Questions
Does the oil separator f150 work on both sides?
Yes, but the passenger side is where ninety percent of the oil vapor is pulled.
This hose connects directly to the vacuum source under load.
Most truck owners only install a can on the passenger side PCV line.
Adding a driver-side separator is unnecessary unless you run a high-boost supercharger setup.
Can I clean and reuse the internal filter elements?
Yes, most high-quality canisters feature cleanable stainless steel mesh filters.
During your scheduled oil changes, unscrew the can and spray the mesh with brake cleaner.
Let the filter dry completely before reassembling the housing.
Is a dual-valve canister better than a single-valve unit?
A dual-valve system provides constant vacuum pulling power under idling and boost conditions.
This is beneficial for heavily modified EcoBoost trucks running higher turbo boost pressures.
For daily drivers, a standard single-valve separator provides excellent protection at a lower cost.
Where should I mount the ford f150 oil separator canister?
The canister should be mounted in a cool, easily accessible area of the engine bay.
Mounting it near the radiator shroud makes it incredibly easy to reach.
Keeping the canister away from direct engine block heat helps condense the oil vapors much faster.
