3. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value ▶
Compression ratio16.5 : 1
Test conditionat normal operating temperature (80˚C)
Compression pressur
eStandard32 bar
Minimum18 bar
Differential limit between cylindersMaximum 3 bar
The compression pressure test is to check the conditions of internal components (piston, piston
ring, intake and exhaust vale, cylinder head gasket). This test provides current engine operating
status.
Measurement ▶

Disconnect the fuel rail pressure sensor connector to cut off the fuel injection.
Remove the air cleaner duct and glow plugs. -
-
-
Place the diagram sheet to compression
pressure tester and install it into the plug
hole. 1. Before cranking the engine, make sure that the test wiring, tools and persons are keeping
away from moving components of engine (e.g., belt and cooling fan).
Park the vehicle on the level ground and apply the parking brake.
Do not allow anybody to be in front of the vehicle. -

Components ▶
Cylinder head
Cylinder head contains cam position sensor, vacuum pump, intake manifold, exhaust manifold and
valve assembly. Vacuum pump and the high pressure (HP) pump are driven by Camshaft and valves
are install in vertical direction. This enables the compact layout in cylinder head assembly.

(5) High Pressure System Pressure Test
Fuel rail pressure test ▶
Disconnect the pressure sensor connector
(A) and IMV connector (B) from the fuel
rail. 1.
Connect the pressure tester to the fuel rail
pressure sensor connector. 2.
Crank the engine 2 times for 5 seconds. 3.
Read the highest pressure value
displayed on the tester display.
If the highest pressure value is 1,050 bar
or less, refer to the section "Fuel System
Check Process". -
