Oil only flow up the pushrod when the holes in the end of the pushrod are lined up with the hole in the rocker arm. The size of the hole in the pushrod, and whether it is chamfered or not can affect the flow as can the size and position of the hole in the rockers. Pushrods that are too long or too short will also change the oil hole timing.
