Unhappy Valve Stem Wear Pattern
I installed a set of roller rockers and it was brought to my attention that centering the rocker over the valve stem can result in the valve stem not rotaing - thus causing a wear pattern to develop on the valve stem that can be seen where the roller contacts the stem. This seems to have occurred with me. The instruction sheet that came with the roller rockers is specific about rocker position with regard to certain installations. The reason I centered the rollers was to prevent the pushrods from contacting the manifold. Can anyone comment on this?
