5.0L Oil Catch Can
Seeing as how I've been involved with muscle cars for years and having seen first hand how well oil catch cans work I put one on my 2001 F150 shortly after I got it. For anyone that doesn't know even a perfectly running engine will get some oil that travels up the vent tube from the valve cover to the intake. That oil burns off in the combustion chamber usually and also coats the inside of the intake over time, reduces fuel economy. On a power adder engine it's a big issue because that oil getting into the intake mixes with fuel and essentially reduces the octane level of the fuel you are using and can cause detonation.
This is how it looks installed. The can just sits in line with the vent line and has chambers inside and wire mess that traps the oil to keep it from going into the intake.
This morning I opened it to see how it was working after 1500 miles and this is what I had so far.

A couple of questions:
Why is the hose from the valve cover going into the intake in the first place if this is an issue?
Is there a similar setup on the other valve cover?
I have never had one of these on a vehicle, and have really only seen them on forced induction motors (I have an Ecoboost, hence the curiosity).
Is this really necessary? You would think that Ford would account for this if it is an issue.
Does the Ecoboost even have a similar setup since it is direct injection?
Thanks

It's part of the normal PCV system and they do it for emissions reasons. The other option is to put breathers on the valve covers and vent the crankcase to the atmosphere.
The one on the other side goes to the intake tube and doesn't pull as much vacuum as the one in the intake manifold so usually you just put one on the intake side. Forced induction engines sometimes go with one on each side or breathers.
As for being necessary that is up to you. I've seen forced induction engines detonate due to the oil in there. I've also worked on enough engines to see how nasty the inside of the intake gets with that oil making it's way in there or even gumming up the injectors. Granted that's over time but I'd rather have it on there and prevent some of that mess if possible even though I don't plan on doing anything to this engine.
Most engines have PCV type systems regardless of the fuel system.

That picture in my first post was after 1500 miles with the catch can on. I haven't seen any increase in fuel economy but I think it's more about keeping it from decreasing over time.

The main build up area on the Ecoboost is going to be the valves since it is direct injected. Using good quality fuel and perhaps some seafoam from time to time will help with this. It would still be interesting to see someone put a catch can on an eco tho.

im only seeing one picture. Did you have another picture that was showing how much oil was in the can?
