Why is my intake killing my vac hose?

Somebody must have installed your distributor/oil pump drive shaft off by a few teeth. Either that or you might need to move each of the wires over one position on your distributor cap.

if it happens to be off by a few teeth, then rotating the wires like u say would fix it?

as for the intermediate shaft, i'm not sure I understand which shaft but could probably figure it out if the wire-rotating option fails to produce results...
