Note: Use clean engine oil to lubricate the threads of the cylinder head bolts before assembly.Use the following procedure to tighten the cylinder head bolts:
Torque for bolt (1) through bolt (20) in a numerical sequence to 270 27 N m (200 20 lb ft)
Again torque the bolt (1) through bolt (20) in a numerical sequence to 450 20 N m (332 15 lb ft).
Finally torque the bolt (1) through bolt (20) in a numerical sequence to 450 20 N m (332 15 lb ft).
Install the rocker arm assemblies onto the cylinder head.
Torque for the bolt (21) through bolt (26) in a numerical sequence to 270 27 N m (200 20 lb ft)
Again torque the bolt (21) through bolt (26) in a numerical sequence to 450 20 N m (332 15 lb ft).
Finally torque the bolt (21) through bolt (26) in a numerical sequence to 450 20 N m (332 15 lb ft).Note: Tighten the bolts only after the cylinder head bolts have been given final torque.
