16.8 Disconnect breather pipe (A) from
manifold chamber
B Manifold chamber breather hose (1 of 3)
8 Release the retaining clip and disconnect
the breather pipe from the manifold chamber
(see illustration).
9 Release the retaining clips and disconnect
the three breather hoses from the manifold
chamber (see illustration, also illustration
16.8).
10 Unscrew the brake servo line banjo bolt
from the manifold chamber, discarding both
sealing washers (see illustration).
11 Remove the five bolts securing the
manifold chamber to the inlet manifold.
12 Remove the support stay to manifold
chamber securing bolt.
13 Detach the manifold chamber from the
inlet manifold and discard its gasket.
14 Remove the engine oil dipstick, covering
the open pipe to prevent any ingress of dirt.
15 Disconnect the four fuel injector
multiplugs and the intake air temperature
sensor multiplug.
16 Release the coolant hose from the inlet
manifold (see illustration).
17 Remove the two nuts and three bolts
securing the upper face of the inlet manifold
to the cylinder head, loosening each one a
little at a time.
18 Remove the two bolts securing the engine
wiring harness brackets to the inlet manifold.
19 Release the two clips which secure the
fuel return hose.

manifold
16.9 Disconnect breather hoses (arrowed)
from manifold chamber
20 Remove the bolt securing the support
stay to the inlet manifold.
21 Remove the four bolts securing the lower
face of the inlet manifold to the cylinder head,
loosening each one a little at a time.
22 Remove the inlet manifold, discarding the
gasket.
Refitting
23 Refitting is the reverse of the removal
procedure, noting the following:
a) Thoroughly clean all component parts,
paying particular attention to the mating
surfaces.
b) Always fit a new manifold gasket.
c) Working in the sequence shown (see
illustration), tighten the manifold
retaining nuts and bolts evenly to the
specified torque wrench setting.
d) Tighten all disturbed fasteners to their
specified torque wrench settings (where
given).
e) Renew all sealing washers and O-rings.
f) Remove all masking materials.
g) Ensure all hose connections are securely
remade.
h) Ensure the brake servo line banjo union
alignment tang is located in the manifold
chamber slot.
i) Refill the cooling system and check the
coolant level, then wash off any spilt
coolant.
