Hello,

Here are the instructions and diagram needed to get the job done. See images below.

Install cylinder head to block.
After applying oil to cylinder head bolts, tighten them gradually as follows.

Tighten cylinder head bolts (except hex hole bolt) to 53 N.m (5.3 kgf-m, 38.5 lb-ft) according to numerical order in figure.
In the same manner as Step a), tighten them to 84 N.m (8.4 kgf-m, 61.0 lb-ft).
Loosen all bolts until tightening torque is reduced to 0 in reverse order of tightening.
In the same manner as Step a), tighten them to 53 N.m (5.3 kgf-m, 38.5 lb-ft).
In the same manner as Step a) again, tighten them to 105 N.m (10.5 kgf-m, 76.0 lb-ft).
Tighten cylinder head bolts (hex hole bolt) to specified torque.
Tightening torque

Cylinder head bolt a: Tighten 53 N.m (5.3 kgf-m, 38.5 lb-ft), 84 N.m (8.4 kgf-m, 61.0 lb-ft), 0 N.m (0 kgf-m, 0 lb-ft), 53 N.m (5.3 kgf-m, 38.5 lb-ft) and 105 N.m (10.5 kgf-m, 76.0 lb-ft) by the specified procedure

Cylinder head bolt (hex hole bolt) b: Tighten 11 N.m (1.1 kgf-m, 7.5 lb-ft) by the specified procedure

Crankshaft

Install lower crankcase (1) to cylinder block. Apply oil to crankcase bolts before installing them. Tighten crankcase bolts gradually as follows.
Tighten crankcase bolts (10 mm (0.39 in.) thread diameter) (2) to 30 N.m (3.0 kgf-m, 22.0 lb-ft) according to numerical order in figure.

In the same manner as Step a, tighten them to 42 N.m (4.2 kgf-m, 30.5 lb-ft).
In the same manner as Step a, retighten by turning through 40 .
Tighten crankcase bolts (8 mm (0.31 in.) thread diameter) (3) to specified torque.
NOTE: Tighten 10 mm (0.39 in.) thread diameter bolts first (the following the order shown in figure), then tighten 8 mm (0.31 in.) thread diameter bolts.
Tightening torque

Lower crankcase bolt (10 mm (0.39 in.) thread diameter) a: Tighten 30 N.m (3.0 kgf-m,22.0 lb-ft), 0 N.m (0 kgf-m, 0 lb-ft), 42 N.m (4.2 kgf-m, 30.5 lb-ft) and 40 by the specified procedure Lower crankcase bolt (8 mm (0.31 in.) thread diameter) b: 27 N.m (2.7 kgf-m,19.5 lb-ft) by the specified procedure

RODS

Install connecting rod bearing cap (1) as follows.
NOTE: If connecting rod bolt is reused, mark sure to check connecting rod bolt for deformation referring to "Connecting Rod Bolt Deformation (Plastic Deformation Tightening Bolt)" under CRANK PINS AND CONNECTING ROD BEARINGS INSPECTION .
Point arrow mark (2) on cap to crankshaft pulley side.
Apply engine oil to new connecting rod bolts (3).
Tighten all connecting rod bolts to 15 N.m (1.5 kgf-m, 11.0 lb-ft).
Retighten them by turning through 45
Repeat step d) once again.
Tightening torque

Connecting rod bolt a: Tighten 15 N.m (1.5 kgf-m,11.0 lb-ft), 45 and 45 by the specified procedure.

Please follow the diagrams below let me know if you need anything else to get the problem fixed. Also below you will find an video on the proper use of a torque wrench
