    Hi Jae,

    They send "O" rings because any time you pull a part off that uses and "O" ring you should replace it. The rubber carb socket is an example. When you replace the rubber carb socket it has an "O" ring that seals it against leaks to the air intake manifold. When you do an oil purge you are supposed to pull the valve covers off and check for soft rockers and there are two "O" rings per valve cover.

    I hope this helps explain.

    Hi Jae,

    "O" rings should be changed when you take something apart. If you didn't take it apart then it's okay. If you have it apart already then put the new "O" ring in place. You should replace "O" rings when you take components apart.
