Q: How do you remove and reassemble the valve cover and rocker arm assembly on Honda Fit?
A: To remove the Valve Cover, position the number one piston at Top Dead Center. Loosen the rocker arm valve lash adjustment nuts and unscrew the adjustment screws if necessary. For 2008 and earlier models, use rubber bands to secure the companion intake rockers together before removal, which is advisable for all models to prevent the piston from pushing the rockers apart. Loosen the rocker arm shaft assembly mounting bolts two turns at a time until the spring pressure is relieved, then lift the rocker arms and shaft assembly from the Cylinder Head, noting the dowel pin on the chain end. Caution is advised as the rocker arm pistons, located between the secondary intake rocker arms, are spring-loaded and can come apart once removed. If disassembling and inspecting the rocker arm assembly, slip the rocker arms, pistons, and springs off the shafts from the chain end, ensuring to mark the relationship of the components for reassembly. Clean the components thoroughly and inspect for wear and damage, checking the rocker arm faces, tips, and shaft surfaces for scoring and excessive wear, replacing any damaged parts. Manually push each rocker arm piston to ensure smooth movement; if not, replace the rocker arm set and lubricate the pistons during assembly. Lubricate all components with engine assembly lubricant or engine oil and reassemble the rocker arms onto the shafts in order from the chain end, holding them together with rubber bands. Install the rocker arm assembly to the cylinder head, applying clean engine oil to the bolt beads and threads, and tighten the bolts in sequence to the specified torque, ensuring to snug them down evenly before applying the final torque. Remove the rubber bands from the rocker arms and adjust the valve clearances. The remainder of the installation follows the reverse order of removal, after which run the engine to check for oil leaks and proper operation.
