head gasket must be fitted (ALTO visible) so
that the oil pressure hole in the block is
central in the copper ringed cut-out in the
gasket (photos). Make sure that the gasket
surfaces on head and block are perfectly
clean and free from oil, otherwise the heat
sealing (polymerisation) process of the gasket
cannot take place.
22 Tighten the cylinder head nuts and bolts
to the specified torque, in the sequence
shown in Fig. 1.30. Follow the procedure very
carefully owing to the special type (ASTADUR)
of gasket used which hardens in use. Always
keep a new cylinder head gasket in its
nylon cover until just before it is required for
use.
23 Oil the cylinder head bolts and
washers and allow them to drain for thirty
minutes.
24 Tighten the bolts in the following
stages:
Stage 1 20 Nm (15 lbf ft)
Stage 2 40 Nm (30 lbf ft)
Stage 3 Through 90º
Stage 4 Through 90º (photo)
Retightening the bolts after a running-in
mileage is not required.
25 Fit the timing belt (Section 28).
26 Check the valve clearances (Section 26)
after the camshaft carrier has been fitted
(Section 27).
27 Bolt on the camshaft carrier cover.
28 Reconnect all hoses, leads and controls.
29 Reconnect the battery and refill the
cooling system.
