Hydraulic Valve Lash (HVL) Adjusters: Installation

Pour engine oil into oil feed hole in HVL adjuster bore to remove debris from oil gallery and prelube bore. Apply engine oil to HVL adjusters and install adjusters in cylinder head. Align crankshaft keyway with timing mark on block. See Figure. To complete installation, reverse removal procedure.

CAUTION: Do not rotate or start engine for 30 minutes after replacing HVL adjusters and camshafts. Valve operation before this time could cause valve or piston damage.
NOTE: Valves may make a tapping/ticking sound if air is trapped in HVL adjuster(s) after replacement. Run engine at 2000 RPM until air is purged. If noise persists, locate and replace defective HVL adjuster(s).
