You can remove the plastic ends off the Purolator PCV to get it to go inline with the hoses. If it doesn't quite fit use some hi temp resistant tape around the bottom of the PCV that way it will fit snug into the hoses. Hope this helps.
Since this thread and especially dwildmanj's reply which helped me locate the PCV valve on my '96 2.3L B2300, were very helpful, I am happy to post a picture with the exact location of it.
So here it is. PCV valve location in a '96 2.3L engine. Right under the #2 spark plug on the drivers side. It's the grey plastic thing in the middle of the picture. It was hard to get to it ans people with big hands will have to remove the #2 spark plug cap (which I couldn't pull out with my bare hands). I only removed the electric connector with the red wire which goes to the component that sits right above the PCV valve.

I am going to attempt replacing the PCV on my truck this weekend. (have crappy MPG and figure it needs done anyway @ 151,000) I assume the EGR valve is the silver part above and just slightly towards the back in that pic. Has anyone done this in a 97 2.3L who has advice for someone with big hands and fumbling fingers? Thanks!
On the 2.3L DOHC, the PCV valve is certainly under the intake manifold, but getting to it with a view requires removing the fender splash panel on driver's side. I did this and saw the PCV hanging off a hose as someone has mentioned. The correct valve has 2 parallel tubes.
Now, having done all this, I still can't locate the 2nd hose to hook it up to. It is real murky down there so maybe the hose is hidden in the dirt and grease. Anyone know where that 2nd hose connection is?
Pitifully,

What lies behind us and what lies before us are tiny matters compared to what lies within us.
The PCV valve should only have one metal connector/nipple. When you buy the PCV valve from an aftermarket supplier (e.g., Fram), the PCV valve comes with a plastic adaptor of some sort with two male connectors as you described. This adaptor should be removed and thrown away. It sounds like whoever replaced your PCV valve left that adaptor on. Remove the tube from this adaptor, slip the the adaptor off of the valve, and then reconnect the hose (currently, it sounds like your valve probably is not functioning correctly considering the fact that it blowing air threw the second open connector). Of course, I am referring to a 93 2.3L, yours may be different (considering you had to remove the fender splash panel... didn't have to remove anything to get access to my valve).
Parts houses will generally provide the incorrect after-market PCV valve. The original has no adapters - direct in and direct out with rubber hose on each side of the valve. Hard to see the valve, once changed the second time is a snap.
I recall getting the "wrong" PCV valve from a parts store when I stil had my 81 Mustang 2.3 back in high school. Fortunately the adapter usually is just forced over the straight fitting. Break out a knife and just carefully trim away the plastic on the adapter and it'll come off.
This is one of those parts that costs about the same from Ford. EV-127A or EV-76C are the Motorcraft part numbers for the PCV for the 2.3L SOHC engine.
Well the PCV is installed and now I can idle without stepping on the gas. Now it's off to install a performance exhaust system-Heartthrob Deep-tone catback. My truck needs a facelift. Later.
That adaptor threw me for a loop the first time I changed mine. I matched the part from the fram part's book to the part on the rack. Brought it home, and it looked like the wrong valve. I took it back to the store thinking I grabbed the wrong valve from the rack... nope... It took about 10 minutes to figure out that the plastic piece just slips off.. once removed, it was exactly like the original. Apparently, there is another vehicle out there some where that requires the Ranger valve, but with an additional tube running off of it. Makes sense I guess, why manufactor two different valves when Fram can just add a cheap fix (i.e., plastic adaptor)?
