    i had a question about a Crystal oscillator. the circuit i have seen says i need a Crystal oscillator that is 4mhz and conected to two 22pf caps. is there anyother way i can make a subtitution for it.

    Do you not like the frequency, or is the component the issue?

    Is this for a microprocessor/ microcontroller/ PIC?

    Crystals are used in certain oscillator circuits because they are far more stable and have a much narrower frequency range than a typical RC or LC circuit. If your circuit had anything to do with timing, you would be very unhappy with it's performance if you substituted an LC or RC circuit.
