Replacing PVC Valve?

I'm trying to do some basic maintenance on my Ranger that I bought used less than a year ago. My check engine light keeps coming on and off every few hundred miles, it's off now (knock on wood), so I'm just doing little things (replaced fuel filter today) to try and see if I can get lucky and keep it off.

I noticed that in the manual, which I found online requires a PVC Valve replacement at 100,000 miles. It seems rather important because it's stated at the beginning, before anything else.

My truck is a 2001 2.3 or 2.5 Liter, 4 cyl. 102,000 miles.

I found this...

Hopefully this is what mine looks like, haven't checked yet.

Anyways I'm just looking for some advice on whether this is a pretty important thing to replace, and maybe any advice. It looks pretty simple. Thank you.

yes it is, it will improve your gas mileage, sometimes significantly, not to mention better for emissions. i imagine its really easy to change on a 4 banger, its not that bad on my 4.0.

quick walk down pcv valve history this was one of the first emissions things but now a days it is much more the emissions blow back gases in the crankcase can cause the oil to break down early and sludge to form there by decreasing engine life i replace mine at 50 k its only a 4 dollar part and its worth the extra peice of mind to me

i recently found mine wasn't installed into the crankcase for i dunno how long the previous owner never put it in. No harm never came to the truck but it did ride a lot quieter after installed and btw its on the drivers side under the injectors kinds hard to see but its there.

There is a how to for your motor.Its alot easyer than the how to makes it out to be.I did it the way the how to says and it was the biggest pain in the ***.
https://www.ranger-forums.com/engine-drivetrain-122/how-change-dohc-2-3l-pcv-valve-116900/

You do not have to remove the breather box like the how to says,Nor do i recomend removing to like the how to says. It has a seal on the backside if you messup that seal or overtighten the bolt on the breather box your going to leak oil. Your crank case is on the other side.

Put the front driver side of the truck on jackstands
Remove the front driverside tire
Remove the inner fender(you may not need to remove the inner fender my truck is body lifted so i had lots off room)
Squeeze the retaining ring and pull the pcv out at the same time.
Then take the hose off the old pcv.
Reinstall in reverse order with the new pcv.

Do it the way i posted above,Im posting the link of the how to for the pics so you can find it.Its basicly right above the starter

listen mate youve got the same 4 cyl as i it should not be a 2.3 DOHC it's gonna be a 2.5l and check my last post i told you right where its at its really a simple fix once you spot the hole. Get a flashlight it'll slide right in then it just plug into your upper intake manifold and done good luck

LOL PVC, oops my bad. I work with those too.

Anyways I figured it all out, it turns out the piece where I get my parts wanted $20 for it. He said it was a 2.3 L, still not 100% about that. My sticker under the hood is gone...

I looked at the piece on my truck and it seems very clean, like very clean, no dirt or grime or anything and was still functioning as far as I know.

Should it get cleaned with anything? Like I said its very clean already, maybe the previous owner replaced it already at one point. For right now its going back in.
