    PCV Location 89 Deville

    I have a Chilton but it shows the location of the 4.9 not the 4.5 so I can't seem to find it. Thanks for your help!

    So I took the whole air intake plenum off to make more room, and I still can't find it. :/

    I thought it was on the same spot for both of them on the front valve cover. Just follow the big vacuum hose coming off the throttle body.

    Oops, brougham beat me.

    Thanks guys, I still don't see it but will keep looking. It definitely isn't on the front valve cover where the 4.9 is though. I decided to do my spark plugs too. They are so hard to get to! Got the front half done now it's time to get under the car

    ----------

    Found it! It's behind the power steering pump resevoir (sort of hidden). My hanes manual shows the V8's PCV on the drivers side (4.9) but the 4.5 is on the passenger side behind that resevoir. Thanks for the help!

    Spend the $$ and get a 5 year subscription for your car to www.alldatadiy.com. Chilton and Haynes manuals are next to useless..... far, far too generic.
