    STANDARD PROCEDURE - HYDRAULIC LASH ADJUSTER BLEEDING
    Use this procedure to manually bleed aerated oil from the lash adjuster and remove sponginess. Run the engine, bringing it to operating temperature in order to freshly pressurize and warm the valvetrain system oil supply. Remove cylinder head cover(s). Ensure the rocker arm is positioned on the base circle of the cam . Rotate engine as necessary. For intake rocker arm positions Adjust Special Tool 8351 Release Probe's gauge pin to extend approximately 20 mm (0.787 in.). Then, carefully insert the release probe gauge pin into the lash adjuster service access hole. CAUTION: If probe tip breaks off within the lash adjuster, replace the affected rocker arm. Gently unseat lash adjuster's internal check ball. While the internal check ball is held unseated, press the rocker arm into the valve tip, allowing the lash adjuster to fully collapse. Hold this fully collapsed position for about one second, or longer. Slowly release the rocker arm, thereby allowing the lash adjuster to extend, which in turn refills the high pressure chamber with non-aerated oil. Remove probe to allow check ball to seat. Recheck for sponginess. If the lash adjuster sponginess is not completely or nearly eliminated, then repeat procedure. If the spongy condition cannot be removed, replace effected rocker arm(s).
    For exhaust rocker arm positions: Adjust Special Tool 8351 Release Probe gauge pin to extend approximately 20 mm (0.787 in.). Then, using two release probes, carefully insert gauge pins into the lash adjuster service access holes. CAUTION: If probe tip breaks off within the lash adjuster, replace the affected rocker arm. Gently unseat BOTH lash adjuster's internal check ball at the same time. While the internal check ball is held unseated, press the rocker arm into the valve tip, allowing the lash adjuster to fully collapse. Hold this fully collapsed position for about one second, or longer. Slowly release the rocker arm, thereby allowing the lash adjuster to extend, which in turn refills the high pressure chamber with non-aerated oil. Remove probes to allow check balls to seat. Recheck for sponginess. If the lash adjuster sponginess is not completely or nearly eliminated, then repeat procedure. If the spongy condition cannot be removed, replace effected rocker arm(s). Install cylinder head cover(s).
