Stainless, Bushed PRW Rocker Arms
Post #1 ----- pic#1 ---- bushing material looks like brass. Not a good choice for a bushing. Compare it to the bushing in a full floating connecting rod, which has a similar movement, but with much more force on it.
----- pic#4 very different looking shaft surfaces even though they are side by side. Oil works when its in the right places.
