How to replace the o ring distributor - 1996 Nissan Sentra


Remove the spark plug wires from the distributor. Loosen and remove the distributor mounting bolt(s). Pull the distributor out from the head. The o-ring is on the distributor shaft. The old one probably needs to be cut off. The new one will stretch and slide into place over the shaft. Put some engine oil on the o-ring, and re-insert the distributor. You will need to turn the shaft to the right position to get it to fit back in place.

If you suspect that your distributor is leaking oil because of a bad o-ring, a new o-ring may fix the problem. However, make sure that the distributor shaft bearing seal is not leaking. You can check this by removing the distributor cap and looking for oil inside the distributor. If the bearing seal is leaking, replacing the o-ring will not solve the problem. You will need to rebuild or replace the distributor.
