See appropriate TORQUE SPECIFICATIONS table. 3) Replace camshaft and/or cylinder head if oil clearance is not within specification. See CAMSHAFT table. Check camshaft end play with camshaft bearing cap bolts tightened to specification. Replace camshaft and/or cylinder head if end play is not within specification. See CAMSHAFT table.
