      NOTE:

      Slide only the upper part of the valve lift control actuator connector clip, as the straight pin will fall out from the bottom if the valve lift control actuator connector clip is completely removed.

    2. Rotate the crankshaft clockwise until the intake camshaft position at the No. 1 cylinder and No. 3 cylinder are as shown in the illustration.

      HINT: 

      If the intake camshaft position is not as shown in the illustration, rotate the crankshaft clockwise again so that the intake camshaft is aligned as shown in the illustration.

      NOTE:

      Do not drop the straight pin into the engine.

      HINT: 

      • The straight pin can be removed by utilizing the space between the continuously variable valve lift controller assembly and camshaft housing sub-assembly to move the continuously variable valve lift controller assembly so that there is no load on the straight pin.
      • If the straight pin cannot removed easily, slightly turn the crankshaft clockwise and then counterclockwise.
      • If the straight pin could not be removed using a Magnet Hand, proceed to *1. If the straight pin could be removed, proceed to *2.
