Running into an odd issue when I'm priming the oiling system on my engine. After spinning for a bit, oil will come out of all the pushrods except the front-most one on the driver's side. All the rockers will be full of oil, and that one will still be dry. Oil comes out of the lifter with the pushrod removed, pushrod is clear of obstructions, but no oil is reaching the top. Ideas?

Check the pushrod end to make sure it is round. check the lifter surface as well. Also have you tried a bit of heavier assembly lube to create a seal before you start priming.
