Remove :
- the cylinder head bolts except for (F) which
must simply be loosened, then pivot the cylin-
der head around the bolt.

CLEANING
It is very important not to scratch the gasket faces
of the aluminium components.
Use the Décapjoint product to dissolve any part of
the gasket which remains attached.
Apply the product to the parts to be cleaned; wait
about ten minutes, then remove it using a
wooden spatula.
Wear gloves whilst carrying out this operation.
Care must be taken whilst carrying out this ope-
ration in order to avoid any foreign bodies ente-
ring the oilways supplying oil under pressure to
the camshaft (oilways are located both in the cy-
linder block and the cylinder head).
Failure to follow to this advice could lead to the
blocking of the jets and thus cause rapid deterio-
ration of the cams and tappets.

Remove the fuel pipe support (7).
Slacken the mounting bolts for the lower timing
cover, without removing them.

Remove :
- the accessories belt tensioning system,
- the cylinder head bolts.
Release the cylinder head by setting aside the
lower part of the lower camshaft housing,
without causing the cylinder head to pivot, since
this is centred by the two dowels at ( C ).
Using a syringe, extract any oil which may have
entered the cylinder head mounting holes .
This is necessary in order to obtain the correct
tightening of the bolts.
Protect the oil outlet duct in order to prevent any
foreign bodies from entering the oilways in the
cylinder head.
Failure to take this advice could lead to the
blocking of the oilways, resulting in a rapid dete-
rioration of the camshaft. F8Q Engine

Replacement of valve adjusters
11
REPLACEMENT OF VALVE ADJUSTERS
In order to carry out this operation it is necessary
to remove the inlet and exhaust manifolds (see
section 12 Inlet/Exhaust Manifolds) .
Fully open the valve concerned (by turning the
engine in its operating direction).
Insert tool Mot. 1366-01 into the duct concerned .
11231R
For inlet valves
Turn the engine in the operating direction,in
order to bring the valve into contact with tool
Mot. 1366-01 (rotate the camshaft by 90° in
relation to the fully open position).
For the exhaust valves
It is vital to turn the engine in the opposite direc-
tion to normal operation (in order to avoid the
locking of the engine), until the valve comes into
contact with tool Mot. 1366-01 (rotate camshaft
by 90° in the relation to the fully open position).
Extract the valve adjuster using a screwdriver and
a magnetic tool.
11232-1R
NOTE : during the refitting of the valve adjuster,
extract any oil which may be in the bottom of the
pushrod bore ( C ) .

REFITTING
Refitting is the reverse of removal. F8Q Engine
