Installation

Valve rocker shaft replacement is an intermediate-to-advanced engine repair requiring removal of the valve cover and proper torquing of rocker shaft retaining bolts to factory specifications. It is strongly recommended to consult the Subaru factory service manual for your specific vehicle and engine code. If you are not experienced with engine valvetrain service, professional installation by a qualified Subaru technician is advised. Always inspect rocker arms, springs, and related hardware during installation and replace any worn components as needed.
