Honda Distributor Oil Seal Replacement

Honda Distributor Oil Seal Replacement

In this video I cover repairing both internal and external oil leaks on 1994-1997 Honda 4 cylinder engine distributors.

Many state if the distributor is leaking internally it can’t be repaired and to buy a new distributor. Well with the right part number and a bit of patience. You can fix that internal oil leak and save yourself at least 180 bucks.

I also address repairing the common outer seal leak as well.

Here are the part numbers you’ll need. There are different part numbers depending on which distributor you have.

You either have a Tec distributor with an external ignition coil or a Hitachi distributor with an internal ignition coil. The Tec distributor caps have 5 wires on them while the Hitachi’s have 4 wires on their cap.

The Hitachi distributors require a bit more internal disassembly but the seal replacement process is identical to the Tec shown in the video.

Tec Part Numbers:

Outer O-Ring Seal: 30110-PA1-732 (From Honda).

Inner Shaft Seal Part Number: NOK BH3888E (Order Online). The dimensions of this seal are 12.5 X 22.5 X 5mm.

Hitachi part numbers:

Outer O-Ring Seal: 30110-PC6-005 (From Honda).

Inner Shaft Seal Part Number: KOK 3286 (Order Online). The dimensions of this seal are 12.45mm X 22mm X 6mm.

If you replace your heater core inlet hose you’ll need to bleed the cooling system.

Here is a link to my video on bleeding the cooling system:

    For those who plan to work on a hitachi …there is no snap ring for the coupler pin. Its pressed in. This means a punch and a big ass hammer to get it out and to get it back in. Just a heads up.
