Hydraulic Lash Adjuster: Inspection
- Inspect components for damage. Measure HLA diameter and bore diameter, and determine oil clearance. Ensure oil clearance is within specification. Replace components if oil clearance is not within specification. See HYDRAULIC LASH ADJUSTERS under ENGINE SPECIFICATIONS.
- Hold HLA upright and attempt to compress adjuster using hand pressure only. If plunger moves, replace HLA.
CAUTION:
HLAs must be installed in original position or rapid camshaft wear will occur. Install NEW HLA if original position cannot be identified.
