CYLINDER HEAD
DESCRIPTION
The cylinder head is made of high temperature
resistant aluminum alloy and features optimized spi-ral swirl intake ducts and a separate camshaft hous-
ing made of die cast aluminum. The combustion
chamber features four valves per cylinder, central
injectors and glow plugs arranged slant wise. The
intake and exhaust valves have solid valve stems and
conical valve springs. The cylinder head is not ser-
viceable and must be replaced should a repair
become necessary.
STANDARD PROCEDURE
STANDARD PROCEDURE - CYLINDER HEAD
BOLT INSPECTION
(1) Measure cylinder head bolts between points
shown (Fig. 12).

Maximum
Length104 mm
(2) If the cylinder head bolt length is greater than
the maximum allowable measurement, replace the
cylinder head bolts.
STANDARD PROCEDURE - MEASURE CYLIN-
DER HEAD SURFACE
NOTE: DO NOT machine the cylinder head surface.
(1) Disconnect negative battery cable.
(2) Remove cylinder head (Refer to 9 - ENGINE/
CYLINDER HEAD - REMOVAL).
(3) Remove valves.
(4) Inspect cylinder head contact surface for flat-
ness, porous and damage.
(5) Using a straight edge, measure cylinder head
and cylinder block flatness.
(6) Measure cylinder head height at point (1) indi-
cated and retain reading (Fig. 13).

NOTE: The camshaft housing Must Not be
machined. Basic bore of the camshaft bearings will
be altered.
(7) Measure cylinder head height (1) at point indi-
cated, record stock removal (Fig. 13) CYLINDER
HEAD SPECIFICATIONS.
(8) Measure valve setback at points (2) indicated
(Fig. 13) CYLINDER HEAD SPECIFICATIONS.
NOTE: If measurement is less than dimension ª2º
no further correct valve clearance compensation is
possible; replace the cylinder head.

INSTALLATION
INSTALLATION - CYLINDER HEAD
WARNING: (Refer to 14 - FUEL SYSTEM - WARN-
ING)
NOTE: Thoroughly clean all mating surfaces with
appropriate solvents and blow out bolt holes, to
assure that no grease or oil is present during reas-
sembly. If piston or connecting rods have been

inder head bolts for defects and stretching before
installation (Refer to 9 - ENGINE/CYLINDER HEAD -
STANDARD PROCEDURE). Inspect facing cylinder
head contact surface.
