Electronic ignition distributor question

[QuebecFiatSpider]

Hello everyone,

Recently I bought a new electronic ignition distributor for my Fiat spider 2000 FI.

When I opened the box to look at what I got, there is one detail that got to my attention. I noticed two small holes under the base of the distributor, which wou can see in both pictures I've taken.

What those two holes are there for?

I'm asking that question because I read somewhere that if some oïl fumes/mist enters the distributor, it may damage the wires or other mechanism Inside. I know that I need to change the seals for new ones in order to make sure oïl fumes does not escape the cam tower….but..in my own opinion, maybe it would be better if there was no holes beneath at the first place!!!

What do you guys think?

Looking at an original Marrelli distributor, those two holes are there as well. Does not answer your question but....

Condensation reduction and pressure equalization through minor airflow. I doubt that too many fumes will enter,...unless your engine is afire!

you would need a BAD internal seal for anything to work it's way through the "internals" of the dizzy.
never heard of anyone even talking about that.

Funny to go back to this and read what I wrote.

haha, that's exactly what I had. oil coming up through the dizzy. new one: no leak; but doesn't idle that smooth.

Could just be tooling holes

Those holes let the oil out when your distributor shaft seal leaks.

yes they do, and right onto the exhaust manifold to smoke. but relatively easy fix
and better than really mucking up the dizzy
