Oil Leak at Distributor - Maybe this O-ring, here?
Hey all! Since I picked up this '67 Delta back in September, it's had an oil leak, and it seems like it's gotten a little worse after the winter.
Eventually, I was able to find the source, and it's leaking from where the distributor meets the manifold. I pulled the distributor yesterday to see if I could find any obvious signs of failure in its sealing, and the only think I can think of is if this O-ring isn't the proper size. The Felpro 424, as suggested on the gaskets thread, looks more O-shaped, and this one almost looks D-shaped:
Just curious what your opinion is, and whether I'm on the right track or not. Tired of leaking oil!
Thank you all, as always.

i try to use something softer than what the oring groove is madeof to remove the old oring. I typically will use a small dowel w the shaft sharpened slightly this allows you to get under and to lift the old oring up and out of the groove w out scoring the groove and leadin to another leak. also when reinstalling if you lay the same dowel along the length of the dizzy and roll the oring up you can make any adjustments before allowing the oring to drop into place.
also a common source of a leak in that area may be from the intake to block seal.

Glad to hear this is kind of common.. I finally got the chance to run the car a bit last night to see if it fixed it, and it's a no go for now. Still getting a leak at the distributor. I'm gonna pull the distributor again tonight or sometime within the next few days to make sure the O-ring isn't twisted or something weird.
I will say, I got the Felpro 424, and it doesn't fill up the groove like the old one did.. kind of loose, in my opinion. I'm wondering if it's not a stock distributor. I'll keep everyone informed as I try to track down the issue.

You can either match the old one to a new one or hand carry the distributor to the local parts store and find one that fits. The ID needs to be snug, the OD needs to fill the groove and protrude enough to seal against the block without binding or getting sheared off.

That's what I was thinking.. didn't look quite right to me. I'll post another pic of the 424 on there, if I get the chance, just for a closer look for all you guys.

I was also wondering about that.. I'll definitely post a pic of the 424 on there and see what you guys think - whether it just needs some grease or not. Thanks!

Here are some more pics of the 424 on it.. I'm curious what you guys think about the fit. These should show the gap I'm concerned with.. also, this is before the grease suggestion. And, I did notice a bit of a gash on one side, some material on the shaft that looked like eraser shavings, so I'm wondering if it bound up and I ruined this one:

That's definitely the right O-ring and the right fit.
There's only one.
The O-ring fills the space when it is compressed by installing the distributor.
What you need to do now is to install the distributor, and then clean off the whole rear shelf area thoroughly with Gunk or something similarly powerful, then drive the car and look to see where the leak is coming from - you won't be able to tell while it is all greasy.
Odds are it's the rear manifold seal.
