Camshaft & Valve Lash Adjusters: Installation

1. Fill valve lash adjuster pockets on cylinder head with clean engine oil. Ensure oil comes out of oil passages. Lubricate valve lash adjusters and install on cylinder head.
2. Ensure key on crankshaft sprocket is pointing up and aligned with timing mark. See Figure . Lubricate camshafts and install on cylinder head, ensuring pins align with timing marks. See Figure .
3. Apply sealant to exhaust camshaft sealing surface. See Fig 1 . Ensure camshaft bearing caps are marked with an "I" for intake camshaft and "E" for exhaust. Ensure arrow on caps point toward timing chain.
4. Lubricate camshaft bearing cap bolts and tighten them in sequence, in 2-3 steps, to specified torque. See Fig 2 . To complete installation, reverse removal procedure.

CAUTION: DO NOT turn camshafts or start engine for 30 minutes after installing valve lash adjusters and camshafts. Operating engine within 30 minutes and hour may cause valve and/or piston damage.

NOTE: If air is trapped in valve lash adjuster, valve may make a tapping sound when engine is operated. To correct this condition, run engine for 30 minutes at 2000 RPM to purge air from valve lash adjuster. If condition is not corrected, replace defective valve lash adjuster(s).
