Solving the Core Problem with a Ford F150 Oil Catch Can
Your modern Ford F-150 uses direct fuel injection to maximize fuel economy and towing horsepower.
However, this setup means fuel no longer washes over the intake valves to clean away oil vapors.
Over time, sticky blowby gases from the crankcase bake onto these hot valves, causing severe power loss.
Adding a high-quality ford f150 oil catch can intercepts these harmful vapors before they ever reach your engine intake.
Many owners opt for a specialized ford f150 oil catch can dual valve system to capture oil under both vacuum and boost conditions.
Investing in a reliable ford f150 oil separator catch can ensures that your engine breathes clean air.
A robust ford f150 baffled oil catch can uses internal condensation screens to trap fuel, water, and oil droplets efficiently.
If you have been looking for the f150 oil catch can setup that fits your truck perfectly, this guide is for you.
Required Tools and Materials:
- 10mm socket and socket wrench
- Flathead screwdriver (for quick-release tabs)
- High-quality aftermarket catch can kit with model-specific brackets
- Pre-cut PCV hoses with OEM quick-connect fittings
- Shop towels and safety glasses
Estimated Time: 20 to 30 minutes
Difficulty: Beginner DIY
-
Step 1: Locate the Passenger Side PCV Line
Ensure your truck is parked on level ground and the engine is completely cool to touch.
Open the hood and find the factory Positive Crankcase Ventilation (PCV) line on the passenger side cylinder head.
This black plastic tube connects the valve cover directly to the intake manifold port.
Always wear safety glasses to prevent residual engine fluids from splashing into your eyes.
-
Step 2: Disconnect the Factory PCV Hose
Locate the grey or blue quick-release plastic tabs on each end of the factory PCV line.
Gently press the release tab with your thumb or a small flathead screwdriver while pulling the hose away from the port.
Be extremely gentle during this step because these plastic factory fittings can snap instantly under pressure.
Set the factory hose aside in a safe spot in case you ever need to return your truck to stock configuration.
-
Step 3: Mount the Catch Can Bracket
Locate the designated mounting hole on your passenger side engine bay, typically near the radiator shroud or battery tray.
Align the custom mounting bracket from your aftermarket kit with the factory hole.
Secure the bracket firmly using the provided 10mm bolt and tighten it to the manufacturer specifications.
Double-check that the bracket does not rub against any surrounding wire harnesses or air conditioning lines.
-
Step 4: Install the Catch Can and Connect the Hoses
Screw the reservoir can onto the mounted bracket head until it is completely snug.
Attach the “Inlet” hose of your ford f150 ecoboost oil catch can to the passenger side valve cover port.
Run the “Outlet” hose directly from the top of the catch can to the intake manifold port.
Listen carefully for an audible click on both quick-connect fittings to confirm a completely airtight seal.

Mechanics of the 3.5L and 2.7L EcoBoost PCV Systems
To understand why your truck needs an upgrade, we must look at the mechanics of turbocharged direct-injection engines.
In standard port-injection engines, fuel spray continuously cleans the back of your intake valves.
EcoBoost engines inject fuel directly into the combustion chamber, leaving the intake valves dry and vulnerable.
High-boost turbochargers create elevated crankcase pressure, which forces oil vapor back into your air intake system.
The combination of turbocharging and high compression ratios naturally creates more pressure in the crankcase.
This pressure pushes lubricating oil droplets past the piston rings and into the air intake system.
Using the correct ford f150 engine oil weights is vital to minimizing this excess blowby.
Our comprehensive ford f150 engine oil weights guide explains how oil viscosity impacts your PCV performance.
If you run a high-performance ford f150 ecoboost oil catch can, you will notice a huge decrease in valve carbon deposits.
This simple modification keeps your EcoBoost engine running smoothly for hundreds of thousands of miles.
Best Oil Catch Can F150 Brand Comparison & Warranty Analysis
Choosing the best oil catch can f150 owners trust is essential for proper fitment and filtering efficiency.
Brands like J&L OSC and UPR Products are highly recommended by the online F150Forum community.
These premium kits feature plug-and-play OEM-style connectors and heavy-duty billet aluminum construction.
Premium models offer a dual-valve design that handles vacuum and boost pressures with ease.
Many kits include an easy-drain valve at the bottom of the canister to make routine maintenance faster.
Selecting the best oil catch can f150 offers will save you from loose hoses and annoying vacuum leaks.
Many truck owners worry that installing an aftermarket catch can will void their factory powertrain warranty.
Under the federal Magnuson-Moss Warranty Act, a dealership cannot legally deny a warranty claim unless they prove your aftermarket part caused the failure.
To protect your warranty, always refer to the official ford f150 engine oil viscosity guide to maintain proper lubrication standards.
Following the precise ford f150 engine oil weight specs ensures your dealership has zero excuses to deny coverage.
DIY Maintenance: How Often to Empty the Accumulated Blowby
Installing an f150 oil catch can is not a set-it-and-forget-it modification.
You must empty the collected fluids regularly to prevent the reservoir from overflowing back into your engine.
We recommend checking the can every 2,500 to 3,000 miles, which conveniently aligns with your routine oil change schedule.
During cold winter months, water condensation mixes with fuel vapors, causing the can to fill up twice as fast.
It is incredibly satisfying to see the nasty gunk you successfully kept out of your engine valves.
Simply unscrew the canister, pour the contents into an approved waste container, and spin the can back onto the bracket.
Overcoming Common DIY Mistakes
Many first-time installers accidentally route the PCV hoses backwards during setup.
Connecting the lines in reverse disables the check valves, which can lead to dangerous pressure buildup inside your crankcase.
Another common mistake is forgetting to empty the canister during freezing winter weather.
If the mixture freezes solid, it will block the PCV system and blow out your engine main seals.
Taking your time and double-checking your work will save you from these easily avoidable headaches.
Frequently Asked Questions
Will an oil catch can void my Ford warranty?
No, a catch can does not automatically void your vehicle warranty.
The dealership must prove that the catch can directly caused an engine failure before denying a warranty claim.
Do I need a catch can for a Coyote V8 engine?
The Coyote 5.0L V8 engine benefits from a catch can, but it is less critical than on the turbocharged EcoBoost engines.
Coyote engines use port injection alongside direct injection, which helps wash the intake valves clean naturally.
How do I dispose of the collected fluid?
Treat the captured blowby fluid exactly like used motor oil.
Bring it to your local auto parts store or recycling center for proper, safe disposal.
