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

    2. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4.0 kgf/cm 2, 57 psi).
