2. Clean mating faces of cylinder block, cylinder
head and manifold.
CAUTION: Do not use a metal scraper or
machined surfaces may be damaged.
3. Ensure bolt holes are clean and dry.
4. Apply sealant, Part No. STC 50550 to cylinder
head and notches in cylinder block.
5. Fit new gasket seals, ensuring the ends
engage correctly in notches.
6. Apply sealant, Part No. STC 50550 to gasket
seals above the notches in the cylinder block.
7. Fit new manifold gasket, dry.
8. Position gasket clamps, fit and lightly tighten
bolts.
9. Position inlet manifold assembly to cylinder
head.
10. Fit manifold bolts and, working in the sequence
illustrated, tighten as follows:
l
Initially, tighten bolts numbered 1, 4, 9 and
12 in numerical order to 5 Nm (4 lbf.ft).
l
Inlet manifold bolts - initial tighten = 10 Nm
(8 lbf.ft).
l
Inlet manifold bolts - final tighten = 51 Nm
(38 lbf.ft).
l
Tighten inlet manifold gasket clamp bolts to
18 Nm (14 lbf.ft).
l
Tighten inlet manifold bolts to 51 Nm (38
lbf.ft)
11. Clean mating faces of rocker cover and cylinder
head, ensure that bolt holes are clean and dry.
12. Fit new rocker cover gaskets, dry, position
rocker covers, ensuring gaskets are correctly
located.
13. Fit new 'patched' multi-hex rocker cover bolts
ensuring that short bolts are on sides of rocker
coves nearest centre of engine.
14. Tighten bolts by diagonal selection to:
l
Stage 1 - 3 Nm (2.5 lbf.ft)
l
Stage 2 - 8 Nm (6 lbf.ft)
15. Ensure that outer rim of each gasket is correctly
positioned around periphery of rocker cover.
16. Secure ht leads to rocker cover.
17. Clean coolant outlet elbow mating faces.
