To remove the valve cover, position the engine at TDC for the number 1 piston and remove the timing belt. Loosen the rocker shaft mounting bolts 1/4-turn at a time in the reverse of the tightening sequence until the spring pressure is relieved. Lift the rocker arms and shaft assembly from the cylinder head, keeping the rocker assembly mounting bolts in place to maintain the order of components. If disassembling and inspecting the rocker arm assembly, remove the mounting bolts and slip the rocker arms and springs off the shafts, marking the relationship of the shafts to the bearing caps to ensure proper reassembly. For 2002 and later models, keep the three intake rockers for each cylinder together with a heavy rubber band, while for 2001 models, wrap the secondary and primary rocker arms similarly. Clean the parts thoroughly and inspect for wear and damage, checking the rocker arm faces, tips, and the surfaces of the shafts for scoring and excessive wear, replacing any damaged parts. Ensure the oil holes in the shafts are clear and check the roller tips for wear and smooth operation. Remove and clean the lost motion assemblies, checking for smooth plunger operation, and verify the smoothness of the VTEC pistons in each intake rocker arm. Lubricate all components with engine oil and reassemble the shafts, noting the markings and differences between left and right side parts when installing the rocker arms, shafts, and springs. Coat the wear surfaces of the rocker arms with camshaft installation lubricant and install the rocker arm assembly, tightening the rocker shaft mounting bolts gradually according to the recommended sequence to the specified torque. The remainder of the installation follows the reverse order of removal, after which check the valve clearance and adjust as necessary, then run the engine to check for oil leaks and proper operation.

Clean old liquid gasket from the cylinder head and apply a new bead before installing the rocker arm assemblies and tightening the bolts in a spiral pattern.
