Full-Race Catch Can Breather Kit for 2015+ F-150 Ecoboost
When it comes to turbocharged EcoBoost engines, no topic generates more debate than Catch Can and PCV configuration. Turbocharged Direct Injection engines inherently have a higher amount of “blow-by” that does not get washed off the valves and cylinders like a port injection engine. How do we avoid this issue to begin with? You need a good quality catch can, located between the valve covers and the turbocharger inlet.
F-150 EcoBoost Oil Catch Can Kit Includes:
- Full-Race Oil Catch Can Kit
- Full-Race PCV Delete (3.5L) (For the 2.7's you will need to remove your PCV and remove the spring/plunger)
F-150 EcoBoost Oil Catch Can Kit Features:
- Hand fabricated, professionally TIG welded.
- Eliminates Oil from entering the intake manifold
- Deletes the PCV valve and Eliminates 2 common boost-leak points
- Direct Replacement: Plug-and-Play – No tuning required
- No cutting or permanent modifications required – 100% Bolt On!
What’s wrong with the factory PCV system?
- The PCV valve is used to vent crankcase fumes while the engine is out of boost. Once the engine is in boost, the PCV should shut and all pressure gets routed through the one valve cover, venting crankcase vapors into the turbo inlet. The PCV is only a simple vent hose with check valve, between the valve cover and intake manifold plenum. All PCV check valves are designed to open during vacuum/light throttle/decel and shut during boost, sealing the system. The crankcase vent air that escapes through the PCV contains oil vapor, water vapor and other combustion byproduct gases. That vapor normally ends up in your intake tract and most of it gets burned. The rest of it collects on the inside of the intake manifold, the intake ports, and the back of your intake valves, baking on over time to create a hard tar-like carbon buildup. On a turbocharged engine, a dirty or clogged PCV valve can affect performance and fuel economy: PCV valves may leak with a few thousand miles of baked on oil crud. If stuck slightly open, boost from the IM can enter the crankcase, causing a loss of power.
Why should a performance application gut/delete the PCV valve internals?
- Properly removing the PCV valve’s internal spring and plunger allows for twice the crankcase venting area during boost and provides no chance of oil to enter the Intake Manifold.
Why can’t I recirculate the oil in my catch can back into the oil pan?
- The liquid that collected in the can isn’t just oil; it also contains all sorts of combustion by-products that have made it past the piston rings, as well as liquid water which condenses as the hot gases hit the relatively cool can. So now sitting in the bottom of the catch can is a mix of hydrocarbons (raw fuel and other nasty things), water, and oil. This should not be part of your engine’s clean oil supply
