    I found them for sale on e-bay, but I can't figure out how to remove them and replace them.
    I assume there is a trick to it.

    Unscrew the valve stem, remove the spring and rotate the guide so it can slide out of the slot.

    It could also be one where the valve guide is not on the inside of a spring box, in that case you just unscrew the stem and pull the guide and spring off.

    Olds Ambassadors have a two part valve guide. I don't know if your horn is like that. It really depends on the model and the date made.

    It may also have long metal guides.

    They all follow the same principles.

    That shows what they look like on this on
    I can unscrew the top, take out the spring , but I cant figure out how to maneuver the thing to remove it.
    It fits inside the valve, under the spring. The valve has two closed slots on it, one is wider then the other, just like on the valve guides-
    It seems as thought you have to move thing plastic valvue guid a particular way in order to remove or replace it, but I cant figure it out.
    Maybe if I had a chimp, it could do it for me, but I just cant seem to get it.

    If there is a wider circular hole at the top of the slots, lift the guide into it, rotate the guide 90 degrees and extract through the wider slot. Reverse the order to install the new guide.

    Regards, Stuart.

    Ok, I guess you just have to kinda force it a little to get it to work?
    I hope someone around my area sells them, are they common item in stores?
    Otherwise I guess I''ll be waiting.
    Thanks for the info :-)

    Any repair shop will carry those guides.

    Just thought I'd add to this post...
    for the record, I got new valve guides today and the new ones go in and out much easier then the original ones.
    The new ones, you just stuck them in through the larger slot and turn.
    The older one needed to be forced to get it to turn to the right position.
