Did I hook my catch can up backwards???

SilverBullet00 · Jan 29, 2008

So yesterday on the way home from work my car died 3 times on deaccel. When I got home and poped the hood I noticed that my PCV line going from the oil seperator to the intake plenum was SUCKED flat so hard it was ripping the rubber hose!

I started to think about it, and now I am wondering if I have the seperator facing the right way. Currently I have the flow coming out of the valve cover, through the seperator, and to the intake plenum. So the arrow on the seperator is pointed at the plenum.... is this correct?

If it is, maybe I just need a higher flowing unit?

oh, come on! 25 Views and no responses? Someone has to know which way this things faces... my head hurts from thinking about it!!

I would think this is the correct direction...the flow is going toward the plenum. I'd think the problem is the separator...too restrictive.
I gotta ask why are you going back into the plenum? I thought the idea was to just plumb the PCV to a vented catch can...?

+1! I just disconnected my PCV totally....but because it's no longer hooked up to the plenum there isn't any pressure forcing oil to spray everywhere. Probably if I wanted it to be a bit cleaner I could hookup a catch can or a heaterhose pointing down to the ground, but its winter so I don't care lol

We are all too distracted by your avitar to help you ;-)

Is your PCV valve good ?

Here is an alternative to replacing the broken Ford puke tank:

I don't know if it will keep you emissions legal however as it might fail inspection.

I hate those little seperators. I plumb both of my valve covers into a 1qt vented catch can with a breater on top

I think this is what I am going to do as well... Hide in my inner fender or something...

You can see mine. Not worried about it it's no show car.

sweet, how much oil does it actually catch?

NobleHdwe · Jan 30, 2008

I've seen several topics about this problem. Exactly what is the issue with the PCV valve and all the oil? Sorry to be naive about this.

With FI you get oil blow by that gets into your intake and can help cause detenation (sp?)

i guess what I meant to say was how much oil is in the canister on a weekly basis? Do you see a lot of oil in it?

Not very much. Couple OZ's every now and then. It's mostly condensation with a little oil mixed in.

I'm using the Steeda Oil Seperator. Installed it over a year ago and have no tyet seen one drop of oil in the little glass catch jar. I guess maybe it's because my car only has 37000 miles on it? I know it's hooked up properly.

Look inside your inlet pipe. My motor has less mile than that.

I get about 2 ounces a month out of my JLT can on my 2012 ecoboost f150

Did I hook my catch can up backwards???
