Note: Refer to the warning note in Section 1 before proceeding.
Removal
1. Remove the carburettor as described in Section 12.
2. Drain the cooling system as described in Chapter 1A.
3. Undo the bolt securing the antipercolation chamber mounting bracket to the manifold (see illustration) and position the chamber clear of the manifold so that it does not hinder removal.
15.3. Anti-percolation chamber retaining bolt (arrowed)
4. Slacken the retaining clips, then disconnect the vacuum servo unit hose from the left-hand side of the manifold and the coolant hose from the base of the manifold.
5. Make a final check that all the necessary vacuum/breather hoses have been disconnected from the manifold.
6. Unscrew the six retaining nuts, then manoeuvre the manifold away from the head and out of the engine compartment. Note that there is no manifold gasket.
Refitting
7. Refitting is the reverse of the removal procedure, noting the following points:
- a) Ensure that the manifold and cylinder head mating surfaces are clean and dry and apply a thin coating of suitable sealing compound to the manifold mating surface. Install the manifold and tighten its retaining nuts to the specified torque setting.
- b) Ensure all relevant hoses are reconnected to their original positions and are securely held (where necessary) by their retaining clips.
- c) Refit the carburettor as described in Section 12.
- d) On completion, refill the cooling system as described in Chapter 1A.
