Without 'O' rings (stock distributors primarily do not have the 'O' rings), some oil can get by the O.D. of the lower distributor body and the I.D. of the block. If this clearance is excessive, then the oiling to the passenger side of the block will be lessened. The 'O' rings tend to 'seal' off the clearances.
