ENGINE
DESCRIPTION
This 2.7 Liter five-cylinder Common Rail Diesel
Injection (CDI) engine is an in-line overhead valve
diesel engine. This engine utilizes a cast iron cylin-
der block and an aluminum cylinder head. The
engine is turbocharged and intercooled. This engine
also has for valve per cylinder and dual overhead
camshafts (Fig. 1).

STANDARD PROCEDURE
STANDARD PROCEDURE - COMPRESSION
TESTING ENGINE
(1) Warm up engine to operating temperature
(approx. 80 ÉC, 176ÉF).
(2) Shut off engine.
(3) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL).
(4) Remove glow plugs (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/GLOW PLUG - REMOVAL).
(5) Crank engine several times with the starter to
eliminate combustion residues in the cylinders.
(6) Insert compression tester adapter #8927 (Refer
to 9 - ENGINE - SPECIAL TOOLS) with check valve
installed into glow plug hole of cylinder to be tested.
(7) Connect compression tester hose adapter #9295
to compression gauge and test compression pressure
by cranking engine with starter for at least 8 revolu-
tions.
(8) Carry out test procedure at the remaining cyl-
inders in the same way.
(9) Compare pressure readings obtained with the
specified pressures. If the pressure reading is below
the minimum compression pressure or if the permis-
sible difference between the individual cylinders is
exceeded. Refer to cylinder leak down test.
(10) Remove compression tester and adapter from
cylinder head.
(11) Install glow plugs (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/GLOW PLUG - INSTALLA-
TION).(12) Install engine cover (Refer to 9 - ENGINE -
INSTALLATION).

Permissible Difference
Between Cylinders  3bar (  44 psi)
STANDARD PROCEDURE - CYLINDER LEAK
DOWN TEST
(1) Warm engine to operating temperature.
WARNING: DO NOT OPEN COOLING SYSTEM
UNLESS COOLANT TEMPERATURE IS BELOW 90C
(194ÉF). RISK OF INJURY TO SKIN AND EYES AS A
RESULT OF SCALDING WITH HOT COOLANT
WHICH SPLASHES OUT. RISK OF POISONING
FROM SWALLOWING COOLANT. OPEN CAP
SLOWLY AND RELEASE PRESSURE. STORE COOL-
ANT IN PROPER CONTAINERS ONLY. WEAR PRO-
TECTIVE GLOVES, CLOTHING AND EYE
PROTECTION.
NOTE: Turn cap carefully as far as first detent,
release pressure, then unscrew cap.
(2) Open cooling system cap at coolant recover
pressure container.
(3) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL).
(4) Unscrew oil filler cap.
(5) Remove glow plugs (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/GLOW PLUG - REMOVAL).
NOTE: Crank engine at crankshaft in direction of
rotation of the engine (clockwise).
(6) Position cylinder to be tested to ignition Top
Dead Center (DTC).
NOTE: Calibrate cylinder leak down tester and
remove check valve in screw-in fitting.
(7) Connect cylinder leak down tester and follow
INSPECTING Instruction.
INSPECTING
NOTE: If crankshaft rotates, install retaining lock for
crankshaft/ring gear.
(1) Pressurize cylinder with compressed air and
read off pressure loss at cylinder leak tester. If exces-
sive pressure loss exists, determine possible cause
(Refer to 9 - ENGINE - STANDARD PROCEDURE).
VAENGINE 9 - 3

NOTE: If the retaining lock is installed, remove it,
rotate engine and install lock once again.
(2) Carry out test of other cylinders in the firing
order of engine.

STANDARD PROCEDURE - DETERMINING CYL-
INDER PRESSURE LOSS
If an increased pressure loss was found with the
cylinder leak test, inspect the engine by listening at
the cylinder head gasket, air intake area, exhaust, oil
fill opening and where injectors and glow plugs enter
the cylinder head. Also check the engine coolant in
the radiator or expansion reservoir for the formation
of bubbles.
Possible causes for the pressure loss are:

It is possible to pin point the pressure loss of the
relevant cylinder by spraying with clean engine oil.
Engine oil seals off the gap between the piston and
cylinder wall briefly. If a reduced pressure loss now
occurs for a short time, the cause is very likely to be
the pistons, piston rings or cylinder contact surfaces
of the relevant cylinder.
Determining the cause can be falsified by the posi-
tion of the piston ring joints. If suspicion exists that
the loss of pressure is caused by the piston ring
joints being positioned directly one above the other,
fit the parts to the engine and repeat this test after
running the engine for a short time.
