Installing Your Passenger Side Oil Separator F150 Kit
Before beginning the installation, gather your tools and prepare your work area.
You will need a basic 10mm socket wrench, a flathead screwdriver, and a pair of pliers.
This DIY project takes approximately 20 to 30 minutes to complete.
No permanent modifications to your engine bay are required for this project.
-
Locate the Passenger Side PCV Line
Pop your truck’s hood and locate the factory PCV (Positive Crankcase Ventilation) tube on the passenger side cylinder head.
This plastic line runs directly from the valve cover to the intake manifold port.
Ignoring this critical line allows dirty oil vapors to bake directly onto your intake valves.
Always ensure the engine is completely cool before touching any components under the hood.
-
Remove the Factory PCV Tube
Carefully press the quick-release plastic tabs on both ends of the factory OEM hose.
Gently pull the hose away from the connection ports without twisting or bending them too hard.
Breaking these plastic connectors can lead to frustrating vacuum leaks that trigger check engine lights.
Store the original tube in a safe place in case you ever need to return the vehicle to stock.
-
Mount the Oil Separator Bracket
Position the mounting bracket near the battery tray or passenger side fender wall using the provided hardware.
Use your 10mm socket to secure the bracket firmly so it does not vibrate during daily driving.
Make sure there is enough clearance to easily access and unscrew the reservoir cup later.
It is a massive relief to feel how solid the bracket mounts to the frame of your truck.
-
Route the Plug-and-Play Hoses
Attach the custom hoses from your new ford f150 oil separator catch can directly to the open engine ports.
The hose coming from the valve cover must connect to the inlet side of the canister.
The outlet hose then routes directly back into the intake manifold port.
Push the connectors firmly until you hear a satisfying click that confirms a leak-free seal.
-
Verify Clearance and Double-Check Seals
Double-check that no hoses are kinked, pinched, or rubbing against hot engine parts.
Start your engine and listen carefully for any whistling sounds that indicate a vacuum leak.
Finding a clean, leak-free installation on the first try is incredibly satisfying for any DIYer.
Team Vroomdan recommends checking the fittings again after your first fifty miles of driving.
At Vroomdan, we believe that taking control of your truck’s maintenance should be simple and stress-free.
We regularly publish extensive guides on Vroomdan to help you master DIY truck care and avoid expensive shop fees.
Why the Passenger Side PCV Line Suffers from Blowby
Modern direct-injection engines do not wash their intake valves with fuel from the port injectors.
As a result, oil-laden vapors from the crankcase cook directly onto the hot intake valves over time.
This sticky crust restricts airflow, which causes rough idling, misfires, and reduced fuel economy.
Installing a high-quality ford f150 oil catch can acts as a reliable mechanical barrier to capture these contaminants.
It is heart-wrenching to watch your expensive truck lose its factory power due to avoidable carbon crust.
Expert mechanics on F150Forum consistently advise adding a passenger-side separator within the first ten thousand miles.
EcoBoost vs. Coyote V8: Choosing the Right Separator
EcoBoost twin-turbo engines generate massive crankcase pressure under heavy boost conditions.
For these forced-induction engines, a specialized ford f150 oil catch can dual valve system is often recommended.
These dual-valve configurations provide vacuum pull under both cruising and boosted driving conditions.
On the other hand, the naturally aspirated 5.0L Coyote V8 operates wonderfully with a single passenger-side unit.
The passenger side is the primary source of oil vapor because of the engine’s natural rotational dynamics.
Selecting a robust ford f150 baffled oil catch can ensures that even the finest oil mist is condensed and collected.
Preventative Maintenance and Emptying Your Oil Catch Can
You must empty your oil separator regularly to prevent the collected contaminants from being sucked back into the engine.
Most truck owners check the canister during every routine oil change to keep things simple.
It can be incredibly shocking to see the dark, toxic soup of fuel, water, and oil collected in the can.
In colder winter climates, condensation increases rapidly, requiring you to empty the container every thousand miles.
Utilizing the correct ford f150 engine oil weights is also crucial for minimizing overall crankcase vapor generation.
Refer to our comprehensive ford f150 engine oil weights guide to make sure you are using the optimal viscosity for your climate.
Choosing the right oil viscosity directly reduces the volume of blowby gas passing through your PCV system.
For a deeper look at viscosity ratings, consult our ford f150 engine oil viscosity guide.
| Engine Type | Recommended Separator Type | Recommended Emptying Interval |
|---|---|---|
| EcoBoost 2.7L / 3.5L | Dual-Valve or Baffled Can | Every 2,500 miles (monthly in winter) |
| Coyote 5.0L V8 | Single Passenger-Side Baffled | Every 5,000 miles (with oil changes) |
| PowerStroke 3.0L Diesel | Heavy-Duty Baffled Can | Every 4,000 miles |
Common Pitfalls During Separator Installation and Maintenance
One of the most common errors is installing the hoses backward on the canister ports.
If the inlet and outlet hoses are reversed, the internal baffle cannot condense the oil vapor properly.
This simple mistake allows all the oil blowby to pass straight into your intake valves anyway.
Another frequent mistake is ignoring the canister during freezing winter weather.
The absolute horror of a frozen PCV line causing a blown main engine seal is a nightmare no owner wants to face.
Make sure you use high-quality, reinforced hoses that will not collapse under heavy vacuum pull.
Frequently Asked Questions
Will installing a passenger side oil separator void my Ford warranty?
No, the Magnuson-Moss Warranty Act protects consumers from having their entire warranty voided by aftermarket parts.
Ford must prove that the aftermarket separator directly caused a specific failure to deny a warranty claim.
However, to avoid any stressful arguments at the dealership, many owners temporarily reinstall the factory PCV hose before major service visits.
How often should I drain the collected oil from the reservoir?
For daily drivers in warm climates, draining the canister every five thousand miles is usually sufficient.
If you live in a cold region, you should check it every thousand miles due to high moisture condensation.
It takes less than two minutes to spin off the canister base and empty the contents safely.
Does the driver’s side need an oil separator too?
On most F-150 engines, the driver’s side PCV line experiences very little oil vapor flow.
The passenger side handles the vast majority of crankcase ventilation under standard vacuum.
Therefore, a passenger-side setup provides about ninety-five percent of the total protection your engine needs.
Can I use a generic oil catch can instead of a custom-fit kit?
While universal cans are cheaper, they often require custom bracket fabrication and hose cutting.
High-quality, vehicle-specific kits come with OEM-style quick-connect fittings for a perfect plug-and-play fit.
Saving a few dollars is not worth the constant headache of dealing with cheap, leaking hoses.
