    Unscrew the valve cap.
    Unscrew the valve stem.
    Remove old spring.
    Insert net spring.
    Screw on valve stem.
    Screw on valve cap.
    Get back to practicing.

    Is the problem that you can't unscrew the stem? Sometimes the years of aging set in (like they do for my playing) and the threads become stuck. It may take a bit of coaxing for them to come loose. Don't use any hard tools that could damage the piston or the stem if that is the case. Gentleness is required but they will come loose and then the rest is easy.

    Thanks guys
    I just wanted to be sure not to mess up my baby. Thanks for not calling me an idiot lol.
    Is it not a good idea to use 2 kinds of oil. Should I do a wash if I am switching to a new brand or just wipe it down ??

    Every time that you remove the valves, you should wipe the valves and casings down so that they are bone dry, then reoil. Oil floats on water, any moisture left on the valve, no real lubrication.
