Before you get rid of the rocker arm assembly, you will have to first, take off the
Valve Cover and then take off the
Timing Belt and all these must be done under very important condition that is the engine's no 4 cylinder must be set to TDC. Unscrew the rocker arm assembly mounting nuts and bolts slowly in an outward way from the lower end of the rocker arm to avoid dimensional deformation due to the pressure of the spring and then lift the rocker arm assembly off the cylinder head. If the camshaft is to be removed while other components are left in place, then indicate the position of the timing belt and the camshaft sprocket so that the positions of the parts can be retained, then loosen the camshaft sprocket bolt but not fully remove, this will enable the camshaft sprocket to be turned using a screwdriver just enough to enable the camshaft to be removed and reinstalled without adjusting the timing belt After that, you will need to dismantle the sprocket collar, then to remove the rocker arm assembly. Oil seal is fixed at the back cover of the camshaft sprocket; if the back cover is to be reused, the Woodruff key is to be removed and the camshaft is to be lifted. If the camshaft was worn out, and it was replaced, replace the front oil seal; this can be done by using the back cover to pry it off and place the new seal after installing the new camshaft. It is advisable to clean and inspect the camshaft, rocker arms and shafts and before fitting in into place, the bearing surfaces and lobes ought to be greased using moly-base grease or engine assembly lube. Fit back the rocker arm assembly with the camshaft timing mark facing up and in position with the crankshaft pulley timing mark at TDC. Fix the sprocket to the camshaft, fit the sprocket bolt and a washer and tighten to the required degree of torrue. By applying clean engine oil on the parts, civic the rocker arms and shafts and assemble the rocker arm assemblies with the fronts upward then row the nuts and bolts progressively and up to the torque level. Last of all, set the valve clearances to the values achieved when the engine is cold and replace the valve cover.
