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:
Tighten for bolt 1 through bolt 14 in a numerical sequence to 270 25 N m (200 18 lb ft).
Again, tighten the bolt 1 through bolt 14 in a numerical sequence to 450 20 N m (330 15 lb ft).
Finally tighten the bolt 1 through bolt 14 in a numerical sequence to 450 20 N m (330 15 lb ft).
Install the rocker arm assemblies onto the cylinder head.
Tighten the bolt 15 through bolt 26 in a numerical sequence to 270 25 N m (200 18 lb ft).
Again, tighten the bolt 15 through bolt 26 in a numerical sequence to 450 20 N m (330 15 lb ft).
Finally tighten the bolt 15 through bolt 26 in a numerical sequence to 450 20 N m (330 15 lb ft).Note: Tighten the bolt 27 through bolt 39 only after the cylinder head bolts have been given final torque.
