changed dizzy o-ring and it still leaks????????

[Jkid]

About a month ago i found that my cb was leaking oil....a lot about a whole damn quart a week. so i checked where it was coming from an saw it was the dizzy. i changed the dizzy o-ring that connects to the cam and yeah stopped for like 30mins and has been going strong ever since. could it be that Honda gave me a bad o-ring or what???? only thing i haven't done is buy another dizzy, but i feel that won't help either. has anybody else encountered this problem?

There is an external seal between the distributor housing and the head and an internal shaft seal. From your description, you replaced the outer seal between the distributor and the head (Honda doesn't sell the internal seal). Is the oil leaking around the outside of the distributor, or coming out of the cap at the bottom?

leaking on the outside of the dizzy. Also, should the said o-ring have a vertical play? When i say vertical i mean (with the dizzy detached) with the cap in your hand and you can move the o-ring about 1cm upward and downward?

it happened to me, change your valve cover gasket too, put a new one and tighten your valve cover ... you shouldn't notice any leaks ... sometimes it feels like the dizzy but the cover gasket may be the culprit.
Clean under the distributor with carb cleaner first in order to detect if it still leaks or not .... be careful for the sensor under the dizzy

it can't move there are the groove that go inside the camshaft.

tried it today and there is oil still leaking from that hole.... its getting frustrating.

What hole is it leaking from? Is it coming from the weep hole at the base of the distributor?




If it is then that is the internal seal that is leaking. Inner seal part number - NOK BH 3888E.

You have the wrong size O-ring.

This is the seal you need, direct from Honda it was $8 IIRC.

weird it looks as though it is coming from there... but when i take the dizzy off there is a trail of oil originating from center of the dizzy



the o-ring i got was number six was that the right one. and mines has a external igniter.

#6 O-ring means nothing.

If you take off your distributor cap is there oil inside the bottom of the distributor? You may have to remove the rotor and dust shield to see.

#6 is the external O-ring. Your image does not show the distributor shaft internal oil seal, nor does Honda sell it separately. Honda describes it as part of the housing.

And FYI your coil is external, not the ignitor...

Pwnd myself, Image not showing at work.
Assumed he was saying A size #6 O-ring.

As for the internal seal, We sell them at Honda.
Part number is 30105-BH3888E for 12.5 x 22.5 x 6mm

Any bearing/seal place should be able to provide you with one at those dimensions.

It's about time Honda started to carry and sell these things to the public somewhere. I went to my local Honda parts counter and specifically asked for the NOK BH 3888E and they said that they don't sell them. Had to get it from a machine shop instead. Probably cheaper from the machine shop then the dealer anyway....lol

There's no oil in the Dizzy at all... actually for it the be almost 20yrs. old it looks brand new so i put it back on and started the car and let it run for about five mins after getting to norm op. temp. and no oil leaked. cut the car off and it started dripping! that to me makes no sense.
