Hydraulic Lash Adjuster (HLA)

  1. Store HLAs in upright position, submerged in clean engine oil. Inspect friction surface of HLA for wear and replace as necessary.
  2. To check HLA function, hold HLA in hand. Attempt to compress HLA plunger using finger. If plunger compresses, replace HLA.
  3. Ensure HLA-to-cylinder head oil clearance is within specification. Measure HLA outside diameter of both sections in crisscross pattern. Measure HLA bore in cylinder head at top and bottom in crisscross pattern. See HYDRAULIC LASH ADJUSTER  under ENGINE SPECIFICATIONS. Ensure HLA is installed in original location.
