Distributor o-ring

[TorWheeler]

I have an 86 accord DX with an oil leak between the distributor and the block. I took the distributor off and there are no rubber o-rings or seals of any kind. It was just leaking between two pieces of metal. Is there supposed to be an o-ring on these distributors, and if so, where? I have pictures, but I see no way of posting them. Thanks for the help!

yes there should be an o ring.

But....where? That distributor looks quite different than mine. You can even see where oil was leaking down the into the adjustment screw. From what I can tell both of those dark rings are metal, and there isn't anything to keep oil from leaking, just metal on metal. Do I need to replace the internal seals? Or am I just missing a seal that should go somewhere in this picture?10461

Probably that little black O-ring on the dizzy shaft is worn. Replace that. No other gasket needed I believe.

There is no O-ring on the distributor shaft, unless it's metal. Both of those dark bands are metal. Unless you mean I need to take it apart further?

This here is not metal, it is a rubber o ring that has gotten really really hard. The fact that it even made you think it was metal makes it sound extremely likely that it is leaking.

Guess I'll try something better to cut it. My knife didn't even leave a scratch.

Get a pick underneath it, it will split and crumble if you try to stretch it

[TorWheeler]

Went underneath it with a flat head and it exploded. I hope there aren't any tiny pieces in places they shouldn't be. Never had a rubber o-ring explode, normally they crumble and crack or even turn to mush. Thanks for your help guys, I've never worked on something so old xD

Newer oils seem to be attacking old seals.

[TorWheeler]

Yeah, it had a leak when I bought it. Just trying to go through the issues one at a time so it can be my daily driver. Is there an oil you suggest?

I don't really believe in any oil myths, aside from actual problems like eating cams due to decreased zinc content, but thats not a problem these engines have. The oring was 30 years old, it was already hard before any new oil did anything to it. I use Rotella T6 5w-40, yes its full synthetic diesel oil, but its cheap, diesel oil is high in zinc and molybdenum and synthetic oil can take a beating. Your car is going to spring a few oil leaks here and there, you'll just have to replace them as they go, there are not a lot of seals in the engine. If you want a conventional oil, just grab any name brand 5w-30 or 5w-40, there is hardly any difference between them, but additives are lacking unless you spend big money on Brad Penn or something. I would strongly advise against anything like mobile1 or Royal Purple, that is a terrible oil for anything old. I put Pennzoil Platinum in my Type R, but I wouldn't put it in my Accord just because Rotella is cheaper.
