Lash Adjuster Bleeding Subaru Impreza GC/GF

1. Dip valve lash adjuster in engine oil. Push check ball in using .08" (2 mm) diameter rod. With check ball pushed in, manually move plunger up and down at one-second intervals until air bubbles disappear.
2. After air bubbles disappear, remove bar and quickly push plunger in to ensure it is locked. If plunger does not lock properly, replace valve lash adjuster. Always leave valve lash adjuster submerged in engine oil until it is ready for installation.
