No worries, glad to help a fellow 3 pot engine owner out! The reason I say the misfire may fix itself is that the one of the runners on the intake manifold has a slight advantage to the path of flow for the air (or oil in this case). I think this runner goes to cylinder 3 (if that's the one closest to the battery). There's a possiblity the majority of this oil is going to cylinder 3, hence the misfire in that cylinder alone.
I may be wrong, but that's my analogy. We'll find out soon enough!
