Should be on the drivers side valve cover. The PCV hose should be about 3/8" to 1/2" in outside diameter. You need to run the motor with the intake intact so that air flows through the MAF. I never tried it, but if you disconnect the MAF (unplug it), and try to start the motor, if it will run, you can pour the seafoam down into the throttle body.

Let me see if I can find an illustration showing the placement of the PCV valve.

Ok I couldn't find it but I was able to just pour it in the throttle body. It's outside right now "ventalating" before I take it on its hard drive, lol...

Ok, I never could find the PCV valve, but I might be looking into replacing it today... Is it covered or just sticking out? Do I have to take anything off to get to it?

You don't really need to take anything off. It is on the driver side valve cover. Probably a bit closer to the firewall end than the bumper end, but really it is close to the mid point of the valve cover. If you follow the air intake, where it passes over the valve cover that is just about where it is.

If check out swartlkk diagram post and enlarge it, it is number 8 on the diagram. It should have 90' bent hose coming up off the PCV.

I might be able to take a picture of it on Saturday and post it. Tonight I'll be a little busy.
