    There is an o-ring on the distributor body, inside the bore where it enters the engine, which seals against oil coming past that point. If that o-ring is hardened, shrunk, or damaged; there will be an oil leak at the base of the distributor. The distributor will have to be removed to change that o-ring. Oil could also leak from the valve cover gasket, if that gasket is not properly sealed. And if there is any part which threads into the engine near that point (such as an oil pressure sending unit), it could leak oil if it is loose or improperly sealed.
