Inspect
1 Inspect the oil pump housing for damage.

Figure 6A1 – 291
2 Inspect the oil pump cover for damage.


Figure 6A1 – 292

4 Inspect the outer driven gear for damage.


Figure 6A1 – 294
5 Inspect the oil pump relief valve components for debris or damage.


Figure 6A1 – 295
6 Inspect the primary camshaft chain lower guide for damage. If replacement of t he primary camshaft chain
lower guide is required, r eplace the entire oil pump
assembly as the primary camshaft chain lower guide
is not serviceable separately.
7 If debris or damage is pres ent 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
specificat ion ............................................ 20.0 – 26.0 Nm

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 spro ckets to the camshafts.



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


Figure 6A1 – 346
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.

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 fr ont of the engine.
8 Apply a liberal amount of engine oil to the camshaft bearing caps.


Figure 6A1 – 348
9 Install the camshaft bearing thrust cap (1) in the first journal of the right-hand cylinder head.
10 Install the remaining bearing caps (2) with their orientation mark toward t he centre of the cylinder
head.
11 Hand start all the camshaft bearing cap bolts (3).

12 Tighten the camshaft bearing cap bolts to the correct torque specification and in the sequence shown.

Camshaft bearing cap attaching
bolt torque specification:
Stage 1: .................................................... 8.0 – 12.0 Nm
13 Loosen the centre intake camshaft bearing cap bolts
1 and 2, and the centre exhaust camshaft bearing cap
bolts 3 and 4.
14 Retighten the centre camsha ft bearing cap bolts 1, 2,
3 and 4 to the correct torque specification.

Camshaft bearing cap attaching
bolt torque specification:
Stage 2: .................................................... 8.0 – 12.0 Nm
15 Install the right-hand cylinder head camshaft
sprocket, refer to 3.18 Camshaft Sprocket .

Left-hand Side
1 Select the correct camshaft for the particular
installation location. ID markings can be found 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.

3.22 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 – 362
Clean and Inspect
1 Inspect the stationary hydraulic lash adjuster (SHLA) in the following areas:
• a plugged oil passage (1),
• a scored or worn camshaft follower pivot
area (2),
• a damaged or broken retainer (3), and
• a severely scuffed or worn SHLA body (4).
2 Replace the SHLA as required.
