Rocker problems

So with those rockers where's the oil going to go? It's going to follow the path of least resistance. And what is that, Thru the shaft, out the oiler hole, between the two bushings, around to the top, and exit the pee hole on the top. The bushings get nothing cause it all exited out the pee hole on top of each rocker. = dry worn bushings. You need more volume of oil to keep up!
