2000 NISSAN PATROL engine oil

6. Place transmission into Tool with the control valve facing up.
7. Check foreign materials in oil pan to help determine cause of
malfunction. If the fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)
may need replacement. A tacky film that will not wipe clean
indicates varnish build up. Varnish can cause valves, servo,
and clutches to stick and may inhibit pump pressure.
+If frictional material is detected, replace radiator after
repair of A/T. Refer to LC section (ªRadiatorº, ªENGINE
COOLING SYSTEMº).
8. Remove torque converter clutch solenoid valve and A/T fluid
temperature sensor connectors.
+Be careful not to damage connector.
9. Remove oil strainer.
a. Remove oil strainer from control valve assembly.
Then remove O-ring from oil strainer.
b. Check oil strainer screen for damage.

Crankcase Ventilation System
DESCRIPTION
In this system, blow-by gas is sucked into the air inlet pipe after
oil separation by oil separator in the rocker cover.
INSPECTION
Ventilation hose
1. Check hoses and hose connections for leaks.
2. Disconnect all hoses and clean with compressed air. If any
hose cannot be freed of obstructions, replace.

REMOVAL
1. Remove the following:
+Engine coolant draining
+Charge air cooler
+Air inlet pipe
+Throttle body
+Rocker cover
+Oil level gauge guide
+EGR guide tube
+EGR volume control solenoid valve
+Fuel hose
+Injection tube
+Radiator upper hose
+Radiator shroud
+Cooling fan
+Drive belt
+Vacuum pipe
+Vacuum pump
2. Move the power steering pump.
3. Remove the harness connector from the fuel injection pump.
+After pulling the connector stopper all the way back, remove
the connector.
+When the stopper is pulled all the way back, the interlocked-
connector will come off.
As for installation, when the connector is pushed all the way
forward until the stopper locks, the interlocked-connector is
inserted.
4. Remove the fuel injection pump rear bracket.
5. Remove the chain cover.
+Remove the installation bolts A, B, and C shown in the fig-
ure (left).
CAUTION:
During chain cover removal, seal the opening to prevent
foreign objects from getting into the engine.
6. Fix the internal mechanism of the idler gear (scissors gear
structure).
a. Remove the plug on the front side of the gear case.
b. While turning the crankshaft pulley clockwise, check the
tightening bolt hole of the idler gear internal mechanism
through the plug hole.
+Conduct the visual check using a mirror.
+When checking, note that there are 2 other holes (with no
thread) beside the tightening bolt hole on the idler gear.
