    it is inline with the vacuum line that comes out on the right side of the intake directly behind the throttle body. you have to pull the big black line apart to get to it. start thumpin hoses to hear the rattle and narrow it down, the line continues to run to the back of the engine to the right valve cover. i know its hard to understand but i dont have any pics, sorry

    I think on the 98's the pcv valve is farther back on the passenger side. On my 2000 it was right next to the TB like blue said..

    yep, on 98's it's about halfway down the passenger side fuel rail. It's under that ugly ass black foam bulge.

    You guys switching to the new design part #12572717????? It's supposed to cut down on a possible oil consumption problem through the PCV system.
    Just curious???

    That is the fixed orifice kind right, I installed that pcv valve and it fixed most of my oil consumption issues but i recently had my valve covers off and noticed that there was a lot of nasty orange goo on the bottom of them and i kind of think that the burnt off oil isnt properly being vented and is condensation on the inside of the valve cover because there isnt enough vacuum through that little fixed orifice.

    Yep it's the fixed orifice type.
    You have my attention with what you have found. Very interesting. I bought this PCV as well, but never installed it. When I pulled my throttle body off I didn't really find any oil in the intake, and the original PCV and it's hose is dry. So I didn't install the updated design, I just left it be.
