DUI distributor leaking oil.

[JoeJoe44]

Hey guys. I've got a DUI distributor that i have installed during my engine rebuild and it keeps leaking a lot of oil at the base. Any ideas how i can stop this? I've tried to find a bigger o-ring without any luck.
Thanks.

The one that came with my DUI was too small ,I picked up a few viton seals from the local hardware store. I do'nt remember the size but I used a little lube on the seal to get it in the first time. I have pulled the dizzy twice since to check the drive gear and it has been easy in, easy out with no leaks.

If it's just an o-ring oil leak issue, Classic Inlines sells some replacements for better sealing, and there is some explanation/discussion regarding the issue in this thread:

Good luck!

I had the same problem i put the DUI in the lathe and cut the grove bout twice as wide and used a real fat o ring good to go

If you do a search, you'll discover this has been covered a couple of times. Plus you'll find out why it leaks, and how to get a free O-ring.
