    1. Check the camshaft timing marks.

       Note

       
       

       • Check each timing mark from a viewpoint directly in line with the center of the camshaft and the timing mark on each camshaft timing gear assembly and each camshaft timing exhaust gear assembly.

       • If the timing marks are checked from any other viewpoint, the valve timing may appear misaligned.

    2. Check that each camshaft timing mark is positioned as shown in the illustration.
