Lookin for some feedback on my catch-can setup

[Agentlongwood]

Alrighty, so I never liked the way catch cans are configured for our cars.  They seemed oddly complex, with the T-junctions and what not.  So I put some thought into it and connected a system in a way that I think is better.  Coming to you guys to tell me if I've done something catastrophic by mistake, lol.  So this setup does not need a clean side separator, and it allows you to keep the original oil cap in place.  All the lines are 1/2inch fuel hose, squeezed onto the Ford factory plastic connectors.  It uses no T-fittings, and 2 check valves.  The check valves are not in the usual place though.  I took some pics and labeled the lines to walk you through what I've done.



Line A: Vapors come out of the dirty side and into the center fitting on the catch can.  No need for a check since the PCV unit itself only allows vapors to come out, not in.

Line B: The first vacuum source at the intake manifold, connected to the rightmost fitting on the catch can.  Check valve installed so that when the motor gets under boost it isn't sending boost into the can.

Line C: Second vacuum source.  Connected from the leftmost fitting on the catch can, to the front BOV re-circulation point.  No need for a check valve since this is before the turbo.  Therefore it is never pressurized, and always under vacuum (though the amount of vacuum changes).  At idle it is a teeny but of vacuum, and under boost it provides more vacuum.

Clean side intake: The clean side is where I made the biggest change from the usual setup.  I wanted a source of fresh air for the crank case, without drilling the intake or buying a clean-side separator, or any of that stuff.  So I put an air filter on the factory clean side connection.  But since I wanted it to ONLY allow clean air into the crank case, and not burp oil out, I put the filter at the end of a short section of hose with a check valve in the middle.  There fore nothing comes out of that line, only fresh air in.

So it goes like this.  Fresh air is sucked into the clean side without anything being allowed to flow back out.  It comes out the dirty via Line A and into the can.  Vacuum supplied by lines B and C at idle, and when under boost by Line C only.  But how do you drain the can?  Well I'm glad you asked.  I ran a line from the drain on the bottom of the can, down next to the washer reservoir, and installed a valve at the end under the car.  You can't really see the line from the engine bay, but here is where I put the drain valve.



From that angle, it looks like it hangs really low, but it isn't actually that far.  If you look at it dead on from the side it's maybe 1 inch lower than the lip.

Here are a couple more reference photos





I checked all the connections by to make sure air only flows the direction I want it to.  And yes... I checked by putting my mouth on the hoses and blowing out and in.  Everything flows correctly and you cannot blow the "wrong" direction in any of the lines.

So what do yall think?  Any reason why this setup wouldn't work?  I think I covered all my bases in regards to connections and flow direction... but I'm new at this so any feedback is appreciated.  If I did screw something up, I'm gunna be real mad because this setup cost me a trip to the urgent care.  I cut my left index finger REEAAALLL bad with some garden shears when I was trimming the fuel hoses to length.  I did not feel smart at that moment.

Hope your finger heals quickly!  Almost nothing about cars that is worth doing comes without its share of blood donations.

Hope your finger heals quickly!

Actually I was lazy in getting around to posting this.  I've had it hooked up for weeks.  Wanted to give it time to make sure nothing broke or blew off.  My finger is healed, but it left a pretty sweet looking scar on my finger, lol.

NICE ! I would just Monitor the amount of oil that comes from the CSS - to -Filter! I hope you catch a whopper .  Z

So far there has been zero oil that got to the filter.  It's my daily driver and it's been a few weeks, so I believe the check valve is working properly to prevent anything from coming out of the clean side.  Technically not running a CSS.  Just a breather filter after the check valve in the line.

[Agentlongwood]

So any thoughts on the setup itself?  It does require running the BOVs in vent-to-atmosphere, but other than that it's quick and easy.  Just want yall to double check that there's nothing obviously wrong with it.

Your setup looks good as far as I can tell.
The only thing I would keep an eye is the clean side filter.
Having it lower than the valve cover will allow oil to collect in the hose and possibly saturate the filter media.

The Hose clamps are a bit sharp which can poteniate to another injured finger! I would of went with the T-bolts clamps.  Z

[Agentlongwood]

Agreed about the clamps.  They were what I had laying about... but they are a bit crap.  Don't look very nice either, lol.  I'll get around to replacing them at some point.

Without a check valve on line c, from can to air inlet hose, wouldnt it impede on full evacuation from the dirty side during idle? Where vacuum at idle would be pulling from both lines a and c so you wouldnt  be getting full suction. Where if there was a check valve vacuum would only pull from line a?
