Inspect
1 Inspect the oil pump housing for damage.
Figure 6A1 – 217
2 Inspect the oil pump cover for damage.

Figure 6A1 – 218

4 Inspect the outer driven gear for damage.

Figure 6A1 – 220
5 Inspect the oil pump relief valve components for debris or damage.

Figure 6A1 – 221
6 Inspect the primary camshaft chain lower guide for damage. If replacement of the primary camshaft chain
lower guide is required, replace the entire oil pump
assembly as the primary camshaft chain lower guide
is not serviceable separately.
7 If debris or damage is present within the oil pump, further inspection of all of the engine components is
required.

Reassemble
CAUTION
As there are no serviceable components
within the oil pump, a disassembled oil pump
must be replaced.
Reinstall
1 Align the oil pump gerotor with the crankshaft flats and fit the oil pump assembly to the engine block.
2 Align the pump body (2) with the mounting holes in the cylinder block.
3 Install the oil pump bolt (1), three places, and tighten to the correct torque specification.
4 Install the primary timing chain, refer to 3.16 Timing Chains, Tensioners, Shoes and Guides.


Oil pump attaching bolt torque
specification ............................................20.0 – 26.0 Nm

3.18 Camshaft Sprocket
CAUTION
Setting the camshaft timing is required
whenever the camshaft drive system is
disturbed to ensure the relationship between
any chain and sprocket is not lost. Even when
only one sprocket is involved, multiple
crankshaft rotations will not produce
conditions where correct timing can be
confirmed.
If required, follow the Left-hand Secondary
Camshaft Chain Components reinstallation
procedure to reset the camshaft timing.
Remove
Right-hand Side
1 Remove the right-hand camshaft cover, refer to 3.12 Camshaft Cover.
2 Remove the camshaft position sensors, refer to 6C1-3 Engine Management – Service Operations.
3 Remove the camshaft position actuator solenoids, refer to 6C1-3 Engine Management – V6 – Service Operations.
4 Remove the crankshaft balancer assembly, refer to 3.13 Crankshaft Balancer Assembly.

8 Place the dial indicator tip on the base circle (1) of the
camshaft lobe.
9 Set the dial indicator at zero.
10 Rotate the camshaft until the indicator tip is at the highest point (2) on the lobe. This reading is the lift of
the camshaft lobe.

Reinstall
Right-hand Side
1 Select the correct camshaft for the particular installation location. ID markings are on the rear end
of each camshaft. The ID markings are defined as
follows:
• The first five digits refer to the date and time of
production.
• Example = 3L18H.
• Digits six through nine refer to engine
production code.
• LY7 = Alloytec 190 engine.
• The last two digits refer to position:
• LI = left-hand intake.
• LE = left-hand exhaust.
• RI = right-hand intake.
• RE = right-hand exhaust.

Figure 6A1 – 254
2 Apply a liberal amount of engine oil to the camshaft (1) journals and the right-hand cylinder
head camshaft carriers (2).

3 Position the camshafts (1) on the cylinder head and
assemble the camshaft sprockets to the camshafts.



NOTE
Install the camshaft sprocket bolts but do not
tighten at this stage.

Figure 6A1 – 256
4 Ensure the camshaft lobes are in the neutral position with the flats on the back of the camshafts up and
parallel (1) with the right-hand cylinder head camshaft
cover rail.
5 Ensure the marks on the right-hand exhaust camshaft position actuator and timing chain, made prior to the
disassemble operation are aligned.
6 Ensure the marks on the right-hand intake camshaft position actuator and timing chain, made prior to the
disassemble operation are aligned.

Figure 6A1 – 257
7 Observe the markings on the right-hand cylinder head camshaft bearing caps. Each bearing cap is
marked (1) to identify its location. The markings have
the following meanings:
• The raised feature must always be oriented
toward the centre of the cylinder head.
• The I indicates the intake camshaft.
• The E indicates the exhaust camshaft.
• The number 1, 3, 5 indicates the cylinder
position from the front of the engine.
8 Apply a liberal amount of engine oil to the camshaft bearing caps.

3.21 Stationary Hydraulic Lash Adjuster
Remove

1 Remove the rocker arms from the appropriate cylinder head, refer to 3.20 Rocker Arm.
2 Remove the stationary hydraulic lash adjuster (SHLA) from the cylinder head (2).


CAUTION
• Do not stroke/cycle the stationary
hydraulic lash adjuster (1) plunger
without oil in the lower pressure
chamber.
• Do not allow the stationary hydraulic lash
adjuster to tip over, plunger down, after
the oil fill.


Figure 6A1 – 272
