In the procedure to measure camshaft lobes, ALL of the Specifications Modules and Systems Operation, Testing And Adjusting Modules, INCORRECTLY say the "Maximum permissible difference between actual lobe lift (STEP C) and Specified lobe lift (STEP D) is 0.25 mm (.010 in)." The correct statement follows:
Maximum permissible difference between actual lobe lift (STEP C) and Specified lobe lift (STEP D) is 0.64 mm (.025 in).
In the Valves information, in ALL of the Specifications Modules, the valve seat insert face angle is NOT correct. The correct statement follows:
