Distributor filling itself with oil

So, found the vacuum advance leaking. Thats been changed, and car runs better than ever. Ive got about 60 miles on with no evidence of more oil yet. Hopefully get a bunch more on this weekend, so we'll see of that was it! If not, it comes back out to see if it has the passages i didn't see last time.

I'm floored .
Looking at how that vac advance is mounted thru the case, with the vac canister remote from the body, with a rod thru the the case, I couldn't imagine how vacuum could be created inside the body, never mind how wet those things get inside, while off-roading, absolutely amazing .
