Rocker problem. HELP!!

When I ran the engine on Sunday the only rocker not getting oil was the one in question. All of the rest were getting plenty of oil. I will do the priming test tonight and give you a call. I plan on doing it 2 ways. First with all of the valve train in place. Then if there is still a problem I will take the intake off and see if the problem is down at the lifter.
