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 ***.
How-To: Change a DOHC 2.3L PCV Valve
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
