The distributor o-ring that seals to prevent EXTERNAL oil leaks is one o-ring (no moving-rotating shafts to seal). The seal that keeps the oil out of the INSIDE of the distributor is actually not an 0-ring since it has to seal a spinning shaft, much like the front and rear main oil seals on the crankshaft, but spinning at half the crankshaft RPM (cam timing).
I'm not even sure that internal seal is a serviceable component, most likely you will need a used or rebuilt distributor to fix a leak insde the distributor. The seal usually fails because the shaft bushings in the distributor are worn out and the shaft is wobbling, which wipes out the seal.
Trashing the guy at o'reillys reminds me of some of my customers who were politely invited to search elsewhere for a shop to work on their cars, maybe 5 out of 1500 a year.
