Complete Installation Guide for Your Ford F150 Oil Catch Can Dual Valve System
Direct injection Ford engines are notorious for accumulating sticky carbon deposits on the intake valves over time.
Standard PCV systems dump oil-laden crankcase vapors right back into your air intake tract.
A premium ford f150 oil separator catch can filters out these harmful contaminants before they reach your combustion chamber.
By choosing a dual-valve design, you ensure active vacuum evacuation during both engine idling and wide-open throttle boost conditions.
Before you begin the installation process, gather the required tools and prepare your workspace.
You will need a standard 10mm socket, a flathead screwdriver, safety glasses, and some shop towels.
The entire installation process should take approximately 45 to 60 minutes for DIY enthusiasts.
Step 1: Mount the Main Mounting Bracket
Locate the factory mounting bolt near the passenger side radiator core support.
Use your 10mm socket to loosen and remove the factory bolt safely.
Align the custom dual valve catch can bracket over the hole and secure it using the provided hardware.
Ensure the bracket is firmly seated so it can handle heavy engine vibrations off-road.
Step 2: Disconnect the Factory PCV Lines
Locate the plastic PCV connection on the passenger side valve cover.
Gently press the colored release tabs to slide the factory plastic hose off the fitting.
Be extremely careful not to snap the fragile plastic clips during removal.
Keep a shop towel handy to catch any residual motor oil that might drip from the line.
Step 3: Route the Dual Valve Clean and Dirty Hoses
Connect the dirty line from the passenger side PCV valve directly to the inlet port of the catch can.
Route the primary clean line with the integrated check valve to the intake manifold vacuum source.
Connect the secondary clean line to the inlet pipe before the turbocharger to provide vacuum under boost.
Make sure the one-way check valves are pointing away from the catch can to prevent reverse flow.
Step 4: Secure All Connections and Inspect for Leaks
Push all quick-connect fittings onto their respective adapters until you hear a distinct click.
Double-check that no hoses are kinked or resting against hot engine components.
Start the truck and listen closely for any whistling sounds that indicate a vacuum leak.
Properly maintaining your EcoBoost engine is simple when you have access to step-by-step guides.
Our team at Vroomdan publishes detailed walkthroughs to help you tackle advanced truck maintenance right at home.
Why EcoBoost Engines Require a Dual Valve Catch Can
Standard single-valve catch cans only function when the engine is under vacuum at idle.
When turbochargers spool up, the intake manifold becomes pressurized, closing the primary PCV valve.
A specialized ford f150 baffled oil catch can with two check valves utilizes the turbo inlet vacuum to keep cleaning the crankcase under boost.
Without this secondary vacuum source, pressure builds up in the crankcase, forcing oil past the piston rings.
Many truck owners complain on F150Forum about premature spark plug fouling and severe carbon buildup on valves.
According to the official Ford service manual, keeping the crankcase pressure balanced prevents oil leaks around the oil pan and valve covers.
Installing a dual valve catch can f150 kit is the most reliable way to maintain this balance under heavy towing loads.
Using this system helps prevent the dreaded low-speed pre-ignition issues that can ruin your engine block.
It is incredibly frustrating to pay thousands of dollars in dealership repair bills for problems that a simple filter could have prevented.
Understanding PCV Mechanics Under Boost and Idle Conditions
The positive crankcase ventilation system must adapt instantly to changing load conditions.
When you are idling at a stoplight, the engine draws vacuum directly from the intake manifold.
Under hard acceleration, the turbochargers create boost pressure that closes the manifold check valve.
At this moment, the ford f150 oil separator dual valve redirects the blow-by gases to the low-pressure side of the turbos.
This continuous evacuation prevents oil mist from condensing on your cold intercooler walls.
Many professional ASE certified mechanics recommend checking your catch can every few thousand miles.
You will be shocked by the smelly mixture of fuel, water, and acidic oil captured in the reservoir.
Ensuring your PCV system functions perfectly protects your internal components from corrosive blow-by acids.
Adding a premium ford f150 oil catch can is the best way to safeguard your investment.
Practical Application Guide and Catch Can Maintenance Tips
Operating your dual valve catch can f150 system requires regular monitoring, especially during cold winter months.
Water vapor condenses rapidly inside the cold aluminum canister when temperatures drop below freezing.
If you fail to drain the can regularly, the frozen liquid can block the PCV lines entirely.
A blocked PCV line will pressurize the crankcase and blow out your rear main engine seal.
We recommend draining your reservoir every time you perform an oil change or every 3,000 miles.
Always refer to the ford f150 engine oil weights guide to ensure you are using the correct lubricant for your climate.
Using the proper ford f150 engine oil weights keeps your engine clean and reduces the volume of blow-by gases.
Check the ford f150 engine oil viscosity guide to find the best oil for towing and extreme temperatures.
Adhering to these ford f150 engine oil weight specs ensures your internal seals remain perfectly lubricated.
| Feature / Performance Spec | Single Valve Catch Can | Dual Valve Catch Can System |
|---|---|---|
| Crankcase Evacuation at Idle | Excellent (High Manifold Vacuum) | Excellent (Dual Extraction Ports) |
| Crankcase Evacuation Under Boost | None (PCV Closes Under Pressure) | Excellent (Turbo Inlet Draft) |
| Recommended Engine Type | Naturally Aspirated (Coyote V8) | Twin-Turbocharged (EcoBoost V6) |
| Carbon Buildup Prevention Rate | Moderate (Approx. 50-60%) | Superior (Up to 95% Filtration) |
As shown in the table above, turbocharged engines derive the most benefit from a dual-port vacuum setup.
It brings immense relief to know your expensive turbochargers are protected from oil contamination.
A premium ford f150 oil separator dual valve kit is an investment that pays for itself by eliminating valve cleaning services.
Overcoming Common Catch Can DIY Installation Mistakes
Many truck owners accidentally install the one-way check valves backward during the assembly phase.
A backward check valve will completely block the PCV flow and trigger immediate check engine lights.
Always verify the direction of the arrow stamped on the side of each plastic check valve before securing the hoses.
Another common mistake is routing the hoses too close to the hot exhaust manifold or moving pulleys.
Extreme engine heat will melt the rubber hoses, causing sudden vacuum leaks and rough engine idling.
Ensure you secure all routing lines with high-temperature zip ties to prevent accidental movement.
Never use cheap unreinforced vinyl hoses, as they will collapse under the strong engine vacuum.
Our team at Vroomdan recommends buying pre-assembled braided hoses with OEM-style quick connectors.
This ensures a plug-and-play installation that looks like a factory-installed option.
Frequently Asked Questions
Will installing a dual valve catch can f150 kit void my vehicle warranty?
No, the Magnuson-Moss Warranty Act protects consumers from having their entire warranty voided by aftermarket parts.
A dealership must prove that the catch can directly caused a specific engine failure to deny a warranty claim.
However, we recommend temporarily removing the system before taking your truck in for major engine diagnostics to avoid hassle.
Do I need to clean the internal filter of my catch can?
Most high-quality baffled catch cans use a permanent stainless steel mesh filter that never needs replacement.
You can clean the internal mesh by spraying it with clean brake parts cleaner during your annual maintenance check.
Allow the clean canister to dry completely before re-installing it back onto your mounting bracket.
How often should I drain the catch can in freezing winter climates?
You should check and drain your reservoir every 1,000 miles when temperatures consistently drop below freezing.
The collected mixture contains a high percentage of water, which will expand and freeze inside the canister.
Keeping the system clear prevents ice blockages that could cause sudden crankcase over-pressurization.
Can I install a ford f150 oil separator dual valve kit on a Coyote V8 engine?
Yes, but a naturally aspirated V8 engine does not generate boost pressure in the intake manifold.
A standard single-valve catch can is usually sufficient for non-turbocharged engines.
However, the dual-port system still offers superior filtration capacity for high-mileage work trucks.
