    Use the newer rubber style valve stem seal like in the picture. Much better than the white teflon style.
    I am sure you can purchase them locally. Ask for valve stem seal for 8mm valve.

    The valve guide perimeter might be a good idea to measure as well to make sure seal housing is a snug fit.
