78 ± 2 N•m.
(2) In reverse order to that shown in the diagram, completely loosen
the bolts.
(3) In the order shown in the diagram, tighten the bolts to
20 ± 2 N•m.
(4) Make a paint mark on the top of the cylinder head bolt, and on
the cylinder head, and tighten them to 90° as shown in the
diagram.
(5) Tighten the bolts to 90° as shown in the diagram, and check that
the paint mark on the top of the cylinder head bolt and the paint
mark on the cylinder head are in line.

Fitting the O-ring/fuel high pressure hose
1. Apply a little fresh engine oil to the O-ring.
Caution
Ensure that engine oil does not get inside the delivery pipe.
2. Without damaging the O-ring, twist the fuel high pressure hose
to fit it to the delivery pipe, making sure that it is twisted
smoothly.
3. If the hose cannot be twisted smoothly, there is a possibility that
it may be biting into the O-ring, so remove the fuel high pressure
hose, and check for any damage to the O-ring. If the O-ring is
undamaged, reinsert it into the delivery pipe and check once
more whether the hose can be turned smoothly.
4. Tighten the mounting bolts for the fuel high pressure hose to the
specified torque.
Tightening torque: 5.0 ± 1.0 N•m.
