    Valve guide seals??

    Have any of you replaced the valve guide seals with the motor still in
    the car? If you have how big a job is it? My daughters car has two
    hundred and fourteen thousand miles on it and its statred usuing about
    a quart of oil every two thousand miles. It smokes if it set and
    idles for awhile.

    Generic response due to unidentified engine:
    Place cylinder at compression TDC. Remove spark plug, apply compressed
    air to hold valves on seat (or fill chamber with nylon rope, leaving tag
    end to facilitate extraction, if working under a shadetree.). Remove
    valve cover, rockers, keepers/retainer/spring.
    Replace seal, reassemble. Umbrella-type easy, positive type no so much so.
    Consume beer. Put next cyl on compression TDC, such and so forth.

    Perhaps a leakdown test is in order before investing the time/money in
    seal replacement on a tired motor with worn guides, rings, etc.

    I believe you own a 94 Camaro (previous post) so have a look under
    the hood - the valve covers need to come off... tell me how fun
    that would be.

    Sorry its a 96 camaro with a 3.8. It looks like it would be a bear to
    work on. I have done seals on several 350's in other cars.

    I like to coast down a hill in gear, and floor it. If you get a big cloud
    of oil smoke, that goes away when you accelerate, that shows valve guide /
    seals are poor. Coasting creates extra vacuum which draws oil past worn
    guides.
