Needed tools and materials
Disconnecting the battery
Before installing the distributor o-ring, you would want to disconnect the negative terminal battery. Then, set the crankshaft pulley to o using a 30mm socket. This will allow you to rotate the pulley. Look for the distributor cap and take it out, but remember to keep the connector on top. You can just leave the spark plug wires connected.
Taking note of the orientations
Take note of the rotor's orientation so that you won't get lost once you replace it. The rotor should be facing the spark plug terminal number 1. Remember the position of the distributor and the valve cover as well. Look for the 12mm bolt that's attached to the distributor and unbolt it. Once it's out, you can remove the distributor.
Installation of the new distributor o-ring
Look for the distributor o-ring and remove it. Replace it with a new one. Here's a quick tip: slightly lubricate the o-ring with whatever kind of motor oil you are using; this should make installation easier. Line up the groove of the distributor housing. Then, replace everything back together and you're done!
Make sure to wear protective gear when working on your vehicle to keep yourself from any personal injury. Wear closed-toe shoes to keep your feet protected in case any sharp objects suddenly fall on the ground. Also, wear latex gloves to keep your hands covered because you might get cuts.
