There "should" also be a gasket that goes between the distributor and the plate/cap (NOT Cap & Plate) SO If you don't have those you need to order yourself a set!!!
Great point Terry, how the heck could I have forgotten that step??? Thanks for the save!!!The outer cap has a center stud that passes through the inner cap. On the inside of the inner cap there is an O-ring over the center stud. Many times they harden crack and fall off but sometimes they harden in place so take both the inner and outer caps off together then remove the old O-ring.
