The 1998 Civic distributor is fully electronic, meaning that the timing is set by the Electronic Control Unit, or ECU. The distributor is responsible for sending the spark to the correct spark plug. If the distributor fails, the vehicle will not run properly, or at all. There is also an O-ring on the shaft of the distributor to prevent oil from leaking out of the engine, as well as internal seals to prevent oil from penetrating the distributor. If the internal seals are leaking, as evidenced by oil inside the distributor cap, the distributor must be replaced.
Distributor Removal
Step 1 - Use the screwdriver to remove the mounting screws on the distributor cap. Leave the spark plug wires attached and set the cap to the side.
Step 2 - Using the ratchet, extension and 12mm socket, remove the mounting bolts on the distributor.
Step 3 - Slide the distributor out of the engine. It may be necessary to twist it while pulling it out.
Distributor Installation
Step 1 - Install the rotor onto the new distributor. Coat the O-ring with clean engine oil.
Step 2 - Align the drive lugs on the end of the distributor with the camshaft. Slide the distributor in place. It may be necessary to rotate the rotor to perfectly align the drive lugs.
Step 3 - Install the bolts on the distributor and tighten them. Install the distributor cap and tighten the screws.
TIPS: Allow the engine to cool before working on it. To adjust the timing, loosen the distributor bolts and slowly rotate the distributor until the engine runs smoothly.
