The valves worked fine until oil pressure built up and then both rockers stopped moving. While they have it out, replace the driver side valve cover. Has anyone ever had any problems with the relief in the oil pan? Installing a second oil filter often another brand often gets credit for restoring the oil pressure when the actual solution was the release of the trapped air.
