I don't think that is the problem, I looked at the adjusters and they appear to be in good shape. One possibility is that I have the adjusters backed all the way off in order to improve geometry so perhaps the oil squirt from the hole in the rocker is missing the cup? Maybe a shorter pushrod would work okay? I'm just going to order pushrods with oiling and put it back together. I know that pushrod oiling solves the problem I'm not so sure about the oil squirt theory.
