So far, nobody has mentioned the possibility of worn parts in the rocker arms and supporting mechanism. Quite commonly, there is significant wear on the rocker arms, rocker shaft, or rocker arm pivots. The rocker arms can wear into the shaft, or the shaft can wear into the rocker arms - whichever is softer to allow for excessive clearance. Also consider that the pushrod can wear into the rocker arm and be nearly undetectable except for the noise. Normally, a lifter operates in the center of its travel. As clearances start to increase, the plunger in the lifter operates closer and closer to the top of its travel. Wear can occur at ANY of the above mentioned places, and will begin to cause a buildup of clearances that add up to keeping the lifter at the top of its travel and causing noise.

I would need to check things out for myself. I do NOT believe in "short answers" to every problem. As I have found out over the years, each problem has its own causes and solutions. And, the same problem in one engine may not be the same as the similar problem in another engine.
