6) Fill rocker arm’s oil reservoir with engine oil and install
lash adjuster.
CAUTION:
Do not rotate lash adjuster during installation.
Be careful not to scratch the oil seal.
B2M0414
CAUTION:
When removing valve rocker assembly, keep the
assembly soaked in engine oil, or position it with air
bleeding orifice on rocker arm facing upward as
shown. This prevents oil leakage from and air entering
into the hydraulic lash adjuster. Failure to do so may
cause air to enter the hydraulic lash adjuster, causing
loss in performance.
