Hydraulic Lash Adjusters

  1. Remove camshaft cover. Check movement of each Hydraulic Lash Adjuster (HLA) by pushing downward using hand pressure only. If HLA compresses, replace HLA. To remove HLA, remove camshafts. See CAMSHAFT under REMOVAL & INSTALLATION. Mark location of HLA before removing it from bore. Lift HLA from cylinder head.
    NOTE: If hydraulic lash adjusters are persistently noisy, check with manufacturer for availability of modified adjusters.
  2. Inspect HLA friction surfaces for wear and damage. Replace HLA if required. Coat HLA with engine oil, and install it in original location. Ensure HLA moves smoothly in bore by using small magnet attached to HLA.
