- Use new cylinder head gaskets.
- Be careful not to scratch the mating surface of cylinder block and cylinder head.
Tighten cylinder head bolts.
1. Apply a thin coat of engine oil to washers and bolt threads.
2. Tighten all bolts to 29 N.m (3.0 kgf-m, 22 ft-lb) in alphabetical sequence.
  Then tighten all bolts to 69 N.m (7.0 kgf-m, 51 ft-lb) in alphabetical sequence.
3. Loosen all bolts by 180° with reversing order of assembly and after that loosen them by 180° again.
4. Tighten all bolts to 42 N.m (4.3 kgf-m, 31 ft-lb).
5. Tighten all bolts by 80 to 90° in alphabetical sequence.
6. Tighten all bolts by 40 to 45° in alphabetical sequence.
  CAUTION: Make sure that the tightening angle of bolt does not exceed 45°.
7. Further tighten bolts (a) and (b) by 40 to 45°.
  CAUTION: Ensure that the total "re-tightening angle" [in the steps 6 and 7], do not exceed 90°.
