    		 1. Rotate the crankshaft pulley clockwise. Make sure that the intake secondary rocker arm (A) and the intake mid rocker arm (B) are separated and that the intake secondary rocker arm and the intake mid rocker arm should move independently:
    • If the mid and secondary rocker arms move together, remove the mid, primary, and secondary rocker arms as an assembly, and check that the pistons in the rocker arms move smoothly. If any rocker arm needs replacing, replace the mid, primary, and secondary rocker arms as an assembly, then retest.
    • If the secondary rocker arm moves independently, go to step 2.

    2. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4.08 kgf/cm 2, 58.0 psi).

    3. Inspect the valve clearance
