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.

CHECKING THE GASKET FACE
Check for gasket face bow, using a straight edge
and a set of shims.
Maximum deformation: 0.05 mm.
No regrinding of the cylinder head is permitted.
REFITTING (special notes)
Remove the cylinder liner brackets Mot. 588.
Check for the presence of the centring dowel (A).
98713R1
Position the cylinder head gasket.
Grease the threads and under the bolt heads .
Refit the cylinder head (shortest bolts on the inlet
side ).
Tighten the cylinder head (see section 07
"Tightening the cylinder head").
Refit the timing belt , (see section 11 "Timing
belt").
Correctly refit the heat shields.
Refitting is the reverse of removal.
Fill and bleed the cooling circuit, (see section 19
"Filling and Bleeding").

Open exhaust valve method
Bring the exhaust valve of cylinder n° 1 to the fully open position, then adjust the inlet valve clearance for
cylinder n° 3 and the exhaust valve clearance for cylinder n° 4.
Follow the same method for the other cylinders, in the order shown by the table below.
Inlet valve to be adjusted. Exhaust valve to be adjusted. Exhaust valve to be opened.

Remove :
- the exhaust downpipe,
- the hoses and connectors of the cylinder head
coolant pipe housing outlet,
- the connection at (1) using tool Mot. 1311-06,

- the air filter assembly by disconnecting the
EGR solenoid valve and the air temperature
sensor (unclip the fuel supply pipes from the
air filter housing),
- the air inlet pipe
- the accelerator cable
- the feeds for the heater plugs ,
- the connector of the injector with sensor,
along with the fast idle solenoid valve connec-
tor (5),
- the fuel supply and return unions at (A) and
(B).
Disconnect connector (6) from the diesel fuel fil-
ter, remove it from its support and move the die-
sel fuel filter pipe assembly to one side. Place bracket Mot. 1159 at the mounting of the
coolant pipe on the cylinder block, then remove
the engine support tool.

Remove the fuel pipe support (7).
Slacken the mounting bolts for the lower timing
cover, without removing them.
99173-1R

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

REFITTING (special notes)
Refit the cylinder head gasket selected previous-
ly. This is centred by two dowels at (C).
99173-1R
Bring the pistons to mid-stroke position to
prevent them from coming into contact with the
valves during the tightening of the cylinder head .
Centre the cylinder head on the dowels.
Lubricate the threads and under the heads of the
mounting bolts.
Tighten the cylinder head (see section 07
"Tightening the cylinder head").
Refitting is the reverse of removal.
Refit the timing belt, (see method described in
section 11 "Timing belt").
Fill and bleed the cooling circuit , (see section 9
"Filling -bleeding").
MEASURING THE THICKNESS OF THE CYLINDER
HEAD GASKET
Checking piston protrusion
Clean the piston heads in order to eliminate any
traces of deposits.
Turn the crankshaft in its operating direction
once, to bring piston n° 1 close to
TDC .
Fit tool Mot. 252-01 on the piston.
Fit tool Mot. 251-01, complete with dial gauge
Mot. 252-01. on the plate Ensure that the dial
gauge measuring pin is in contact with the cylin-
der block; then locate the piston
TDC.
NOTE
: All measurements are to be carried out in
the longitudinal axis of the engine, in order to eli-
minate any errors due to tilting of the piston.
99173R
Measure the piston protrusion.
ONLY TAKE INTO CONSIDERATION THE
DIMENSIONS OF THE PISTON WITH THE
GREATEST PROTRUSION.
For a maximum piston protrusion:
- lower than 0.868 mm, use a gasket marked by
a tab with two holes ,
- included between 0.868 mm and 1mm, use a
gasket marked by a tab with one hole,
- greater than 1mm, use a gasket marked by a
tab with three holes. F8Q Engine
