the thing my hand is holding, it's starting to crack and can't find the part for it, I know that the pcv is under the intake manifold and when I pulled the manifold off I just straight piped the pcv down to a catch can

 

What engine?

Where does other end go?

Looks too small for PCV vent/breather hose, but bigger than most vacuum lines

Almost same size as cooling system overflow hose, from rad cap to overflow tank

Or if 2.3l Duratec from degas tank cap to under engine/vehicle, allows coolant to exit under the vehicle if cooling system has a problem

 

2002 Duratec DOHC
Goes from valve cover to intake hose after the Maf but before TB also is it weird to have both a map and maf because I had my scanner and it's reading both of them

 

Its the PCV breather/vent hose

Pulls in filtered air when PCV Valve is open fully, and can pull out blow-by gases if there is too much for PCV to pull in, so blow-by would be sucked into the engine same as if it went thru PCV Valve

MAP data is calculated don't think there is a sensor for it, but might be on a 2002
But you can "see" MAP pressure on 1995 and up Rangers and I know they don't have MAP sensor, computer calculates it using other sensors

 

I can confirm on map and maf together, could I reliably put an air filter on the pcv on the valve cover or would it spew out oil possibly too? If so ill vent it down a bit plug the intake hole and have a filter for that pcv

 

Of all the motors I've worked on this one is very weird

 

Yes, 2.3l duratec in Ranger did have both MAF and MAP, looked it up, at least 2002 did, lol

PCV system is there to pull blow-by gases, and the oil vapor it creates, out of the oil pan and valve cover areas, so yes you can filter it, your mentioned "Catch Can" is suppose to do just that, cool off the hot gases enough to let oil vapor condense so only the blow-by(exhaust) gases are reburned in the engine

 

I find it weird having both the Maf and map, my model is July 2002, and I can just vent both pcvs to a single catch and plug up the intake holes, I'm trying to get the intake to be as clean as possible, already vented the egr out and piped it past the precat but before post cat so egr just bumping exhuast to the exhuast pipe

 

I live where emmissions is not regulated at all

 

There is no PCV sensor

So it is not required.

I think the PCV Valve is on lower block/upper oil pan on the 2.3l drivers side

You can just vent it down, like in the "old days", no PCV Valve, but you will get a drip of oil at the end of that vent hose, so spots in driveway
Plug the breather/vent hose connections as that are not needed unless you are applying vacuum to the oil pan/valve cover area via PCV valve


Back before PCV Valves the lower block or upper oil pan on all vehicles just had a metal tube with 90deg bend point down, nicer units had a filter in the pan or block that reduced oil dripping out the tube but just reduced it didn't stop it
All engines have Blow-by, its just the physics of piston engines, so it has to be vented or its pressure would blow out oil pan or valve cover gaskets.

Vent does need to be big enough for the blow-by amount, so the larger the vent tube the better

And us "old guys" will remember the downside of these vents, beside spots on the driveway, lol
ALL engines would drip this oil, so at a stop sign or stop light there would be more oil on the ground, because running engines sat there longer................then you would get first rain in a few weeks, and the oil would come up and flow on top of the water, like oil does, getting over to where the tires are................

So you come up to stop...........................literally like hitting ICE, there were more than a few rear enders from that, lol

I like PCV systems, but I get why you don't want it

 

Well I park in the street 2nd almost never rains here, 3rd we have scrubbers that scrub the streets 1 to two times a week, 3rd, I'm tired of cleaning the TB and plastic intake, the upper hose on the valve cover is cracking and so just gonna get some tubing and vent down found in manual that it does that and the pcv on the middle of the block is next to the thermostat and knock sensor, right under the intake manifold, illl snap a pic for you to see

 

I'd like to know where the hose to the right of that one goes. The one that is "U" shaped running back under the throttle body neck. I worked on the 2.3 this weekend and can't seem to find the hose or where it goes. Also maybe the name of it?

 

If its the one on the passenger side and hooks up after the throttle that would be pcv it goes under the manifold and behind and back its weird

 

Maybe it's hooked up wrong then as I can't find the hose. I bought this truck and have been finding that a lot of it in the engine area has been Jerry rigged. So..... the pcv valve is right under the intake manifold and the hose that is hooked to it is coming off of the back top of the manifold. I think it supposed to be from the front nipple that I described first. If so where does the back nipple connect to or did it just have a "breather" on it?

 

went from the pcv to manifold,, you want it to be under vacuum though as this engine has very tight tolerances and helps keep the engine running

 

So what goes on the top back of the nipple

 

that goes from the valve cover into the intake tube into the manifold, the best place would be placed before the intake filter so the filter will clean up the air and won't gunk up the intake

 

Don't understand that one to much. Been trying to find pictures out there but not much luck

 

so on the lower half of the air box you'll drill a hole a little bigger than the pcv pipe and basically, and you don't have to worry about a perfect seal since it sits before the air filter, pcv helps pistons seal and prevents condensation in the block
