Start by taking out the Rocker Arm cover when replacing the valve Rocker Arm along with push rods. The engine follows 1, 8, 7, 2, 6, 5, 4, 3 firing sequence and contains cylinders 1, 3, 5, and 7 on the left bank. You should remove the number one cylinder
Spark Plug followed by placing rocker arms together with pushrods and pivot support in a rack where you can store them before their original installation locations. First remove the bolts securing rocker arms and pivot support and the pushrods as well. Step in the inspection and cleaning method for rocker arms and pushrods according to their needs. Reinstallation of these components requires clean engine oil to be used for lubricating both the rocker arms and pushrods alongside the flange of the Rocker Arm bolts. The Rocker Arm pivot support gets installed first before the pushrods can enter the valve lifter sockets but not past the Rocker Arm positions and finally the pushrods must correctly fit inside the rocker arms before proceeding with bolt tightening. Install the rocker arms alongside the bolts before using a Crankshaft turner to reach tdc compression stroke with number one Piston positioned correctly while the number one cylinder rocker arms rest off the lift position. The specified torque requirement for the specified bolts should be 30 nm (22 lb ft) while the engine is positioned at this specific compression stroke. Tighten the exhaust valve bolts on rocker arms 3,4,5 and 6 to 30 nm while tightening intake valve bolts for rocks 2, 6, 7, and 8 to 30 nm. Finish the procedure by putting back the number one cylinder Spark Plug along with the Rocker Arm cover.
