Tighten all bolts in stages:
1 Tighten bolts to 60 Nm (43 ft Ib). ? a Loosen bolt 1, tighten it to 20 Nm :(15 ft Ib). b Angle-tighten to 106° using special tool 5098. c' Repeat this for remaining bolts in sequence shown. c Loosen and tighte n each bolt in turn. 3 Adjust valves. 4 Warm-up engine.
5 Allow engine to cool for 2 hrs. 6 Angle-tighten each bolt a further 45°.

b Tighten bolts to 40 Nm (30 ft.lb) c Angle-tighten bolts 160°-180° 3 Adjust valves
Main bearings
Tightening all nuts in stages:
1 = 30 Nm (22 ft Ib) 2 = Slacken nut 1 3 = Tighten nut 1 30-35 Nm (22-26 ft Ib) 4 = Angle-tighten nut 1 73°-77°
5 = Slacken and retighten the other nuts in the order specified in stages 2-4
Side fastening screws
Tightening torques
The 4 fasteners which hold No.2 and 3 main bearings to
engine block should be tightened to 20--25 Nm (15-18 tt)
after the main bearing nuts have been tightened to the
spec ified torque.
