This process is quite elaborate and many tools are needed and because of this there is need to have all the required tools before starting and these include new camshaft sprocket bolts. Start the process by removing the negative battery terminal and then undertaking the valve cover removal exercise. On the 1.4L engine, remove the
Timing Chain and the two camshaft sprockets, note the location and orientation of brevity of each camshaft cap before loosening the bearing cap bolts in the sequence with which they were tightened. Remove the camshaft(s) from the cylinder head ensuring that the caps are replaced in their rightful positions as much as avoiding the mingling of parts from two different camshafts. Pull out the rocker arms out of the engine and set the arrangement aside for reassembly of the unit, followed by the removal of the hydraulic lash adjusters and placing them with the rocker arms. For the 1,8L The
Timing Belt, camshaft adjuster sprockets, the two camshaft position sensors and the special tool have to be removed from the camshaft ends. The camshaft caps should also be marked for proper orientation, the bearing cap bolts will be loosened, then, carefully lift the camshaft off the cylinder head, with particular emphasis on item organization. Take out the lifters and put them at a place where they can be inserted again. Before assembly, ensure that hydraulic lash adjusters and lifters are worn out and camshaft lobes are damaged. Determine the difference in height of the lobes and check for irregularity by comparing the two; also check the bearing journals and surfaces for signs of wear. During installation, lubricate the rocker arms and lash adjusters before reinstalling them in their earlier positions and lubricate the camshafts and install them. Replace camshaft bearing caps and tighten it in a preset manner and replace camshaft actuator and timing chain. If there is no start, turn the engine with the starter to look for some resistance. Lubricate and install lifters and Camshafts for the 1.8 L for the engine and it is important to take note of the orientation of the Camshafts. Set the camshaft bearing caps with sealant, fit new camshaft oil seal and use a tool to synchronise the camshafts. Lastly, reverse the process, and connect the battery in the unit final stage of installation.
