Compression Pressure Measurement
Notice
Ensure that no gear is engaged and that the vehicle is
protected from rolling.
1. Run the engine to be the coolant temperature 80°C.
2. Remove the fuel injection nozzle.

3. Install the test adapter (1) and connect the flexible
connector (2) to the compression pressure recorder.
Compression Pressure Recorder 001 589 76 21 00
4. Disconnect the vacuum line from the stop unit and
connect the hand vacuum pump to the stop unit.
5. Pump the hand vacuum pump and make the fuel injection
pump in stop position.
Operating PressureApprox. 500bar
Hand Vacuum Pump 001 589 73 21 00
6. Using a starter motor, crank the engine 8 revolutions.
7. Measure the remaining cylinder compression pressure
in the same manner and compare it with service data.
Notice
If out of standard, do cylinder pressure leakage test.
8. Remove the compression pressure recorder.
9. Install the fuel injection nozzle.

Installation Notice
25. Separate the vacuum hose for brake booster.
26. Separate the other vacuum hoses.
27. Remove the propeller shaft from the front axle.
Installation Notice
28. By rotating the crankshaft from the front of engine, remove
the 6 torque converter mounting bolts from the engine
ring gear plate.
Tightening Torque 81 - 89 Nm

Operation at Idling and Mid-Load
lIt show that the throttle valve (19) is closed or very partially
opened and the vacuum pressure in intake manifold is high.
The blowby gas in the crankcase in partial load flows into
the intake manifold through the vent line (20) after passing
the air conditioner bracket (6) and the filter (4). The air
reentered into the intake manifold will be dilluted on the flow
through the restriction hole (11) in the vent line (10).
The circulated engine oil is separated at the air conditioner
bracket (6) and then returns into the oil pan through the
drain pipe (7).
The vacuum pressure generated at the crankcase sucks
fresh air from intake air line(13) through the air admission
and vent connection (17,18).
The fresh air prevents engine oil from being contami-nated
and the air admission and vent connection (17,18) is
designed to control the rapid pressure changes in intake
air line (13).
Operation at Full-Load
lThe throttle valve (19) is fully opened.
All the blowby gases flow into the intake air duct (13) after
passing through the oil separator (15,16) of the cylinder
head cover (14) when fully loaded. This dilluted air will be
supplied to the combustion chamber through the intake
manifold (12).

M161 ENGINE MECHANICAL 1B2-15
Tightening Torque 30 Nm 29. Remove the exhaust manifold and exhaust pipe.
Installation Notice
25. Separate the vacuum hose for brake booster.
26. Separate the other vacuum hoses.
27. Remove the propeller shaft from the front axle.
Installation Notice
28. By rotating the crankshaft from the front of engine, remove
the 6 torque converter mounting bolts from the engine
ring gear plate.
Tightening Torque 81 - 89 Nm

1B2-18 M161 ENGINE MECHANICAL
Operation at Idling and Mid-Load
lThe throttle valve(6) is closed or very partially opened, and
the vacuum pressure in intake manifold is high.
The blow-by gas and the fresh air that is additionally supplied
through the vent connection(D) in the crankcase in partial
load gets supplied to the combustion chamber from the crank
chamber(12) through the oil separation chamber(11), air-
conditioner bracket(10), vent line(9), and restrictor(7)
mounted to the cylinder head.
The circulated engine oil returns to the oil pan through the
oil return pipe(13) at the bottom of oil separation
chamber(11).
The fresh air gets supplied to the crank chamber(12) through
the HFM sensor(1), intake air duct(4), vent line(5), oil
separation chamber(3), chain housing(17), and the timing
gear case cover(15).
The additional supply of the fresh air is needed to prevent
from forming the residues of the engine oil.
