Reworking the 273 Adjustable Rockers

toolmanmike said

Just as a point of reference. I have a pair of originals around. To get the oil hole to line up with the adjusting nut hole in the rocker, I had to remove and reverse the rocker. Then it looks like it lined up. Aparently? the previous owner had these assembled wrong.

Another thing I noticed with my set, there is only one oil hole per rocker and it looks like it should go towards the head (to the bottom) where all the wear is and all the oil is needed. What ever works its way around the shaft to the adjuster hole must be enough for a stock engine to keep the ball and cup lubricated. The small hole in the top must be there for spray to help cool the springs and to help lube the rocker tip to valve tip. There is no specific hole for that. All of my rockers have the holes in the top. Those of you that have plugged holes in a few of your rockers, I wonder if those rockers were placed below the pcv valve or oil fill cap to help prevent them from sucking or leaking oil. As we know, valve covers without baffles can be a problem that way and rockers that don't squirt oil directly at them could help the problem.
