Distributor Leak
After some oil clean-up and some looking i noticed that the under side of my distributor was leaking oil 
. Being the back-yard mechanic i removed the distributor and discovered that it was coming from a vent hole from the underside 
. Now that the distributor is fully removed is this a parts replacement or do i need a new distributor.I dont know what would cause the oil to come from the vent hole? If i get a new distributor would this solve this oil leak problem. Thanks

Was it there? In good shape?

Per Duke's inquiry, this is NOT original. Don't know exactly how its made but sounds like the upper seal and possibly bearing is worn out. It should not be getting oil inside. Put in a good GM unit.

vacuum advance connection
The vacuum advance is connected from the vacuum cannister on the distributor directly to manifold vacuum. What kind of carburetor do you have? If it is a "pre-emission" type it will probably have a small nipple that provides constant vacuum. This is the connection you should use. The later carbs also have a nipple that provides "ported" vacuum. If you have a newer carb that has this feature, you don't want to use this connection. The "ported" connection only provides a vacuum source above idle; there is no vacuum from this port at idle. Connect the vacuum advance to the port that has manifold vacuum at idle. The best way to tell which port is which is to connect a vacuum gauge to each while the engine is idling.
I noticed that aft of the carburator on the manifold there is a small 1 1/2" nipple with a hole through it.When vehicle is running I believe that there is air coming out of it.
Not so sure what you mean by this. If this is an open vacuum port, it needs to be plugged if it is not being used.
