The PCV is in sort of a weird place.
Easiest way to explain is; the decorative "3800" shield that clips onto the fuel rails, also locks onto a little tab at the passenger side.
That tab is part of an upright, plastic cylinder that contains the PCV.
Turn the lid CCW, about 1/8 turn to release it. It has an 0-ring seal on the lid and a coil spring that needs to be pulled out.
I used needle nose pliers to grab the PCV and pull it out.
There is an o-ring on the bottom section of the PCV. Don't loose the o-ring because replacement PCVs don't include one.
If one was to stick shut, your crankcase will pressurize and cause oil consumption issues.
I read someplace if one sticks open that it can effect idle.
I think I only paid $2 for one; so it is a cheap maintenance item.
