AUTIONS:
Replacement of nuts and bolts: Various thread-locking de vices are used on nuts and bolts throughout the vehicle.
These devices restrict the number of times a nut or bolt can be used. See section 100-00 for information.
Remove brake fluid spilla ge immediately from paint work, with clean water.

The
ignition supply is the main power source for the ECM; this supply will be disconne
cted by an inertia switch if the vehicle
is subject to a violent deceleration, as in a collision. The ECM has separate ignition and battery supply inputs. The battery
input maintains the ECM memory as long as the vehicle battery is connected.

1. Open the engine compartment and fit paintwork protection
sheets. Open to the service position.
2. Carefully remove both engine covers, taking care not to
damage the plasti c fixings or the rubber inserts.

3. Disc
onnect the batt
ery ground cable.
Re
move the battery cover.
4. Remove the cam cover from the 'A' bank and the 'B' bank;
including the purge valve, the on-plug ignition coils and the air
intake tube / air flow meter / air cleaner cover assembly. Refer
to Operations 12.29.43 and 12.29.44.
5. Check, and note the valve cleara nces, as described earlier in
this section.
6. Use a rag to wipe up as much oil as possible from the tappet
wells.
7. Valve adjustment involves considerable repetition. A SUMMARY
OF THE PROCEDURE follows:
1. Fit the adjusting tool base plate to one cylinder head.
2. Rotate the crankshaft to position four valves ready for
adjustment.
3. Use the attachment part of the special tool to adjust two valve clearances. Transfer the attachment and
adjust the other two valve clearances.
4. Remove the attachment pa rt from the adjusting tool
base plate.

. WARNING: TH
E FOLLOWING OPERATIONS REQUIRE
THE USE OF COMPRESSED AIR - ALWAYS WEAR SUITABLE EYE
PROTECTION.
Remove, clean and measure the shims.
1. Surround the immediate wo rking area with clean rag
to contain any loose objects and shims displaced by
the compressed air.
2. Use 303 - 590 Air Gun (with a fan nozzle) aimed at the edge of the shim to lift it from the tappet.
Remove the shim from each tappet, noting the
position of each.
15 . Cl
ean and measure the thickness of each shim.
16. Assess the increase or decrease required in shim thickness to
produce the correct valve clearance.
17. Select two shims of the correct size, lubricate each and fit
each to the respective tappet (as calculated in the previous
step). Shims must be fitted with the size marking facing the
tappet NOT the cam.

18 . Loos
en the knurled screws on 303 - 540 attachment to allow
the valve springs to return to their normal position.
19. Check the valve clearance of the two valves. If the clearance
is correct, remove the attachment from the base plate. transfer
the attachment to the other two valves which are in position to
be adjusted.
20. Repeat the adjustment procedure, as described in the
Summary.
21. Refit the cam covers and associated components. Refer to
Operations 12.29.43 and 12.29.44.
22. Refit the engine covers.
23. Check the engine oil level; rectify as necessary.
24. Move the engine compartment cover from the service position
and connect the gas struts.
25. Remove the paint protection sheets and close the cover.
26. Connect the battery and fit the battery cover.
Refe

Gen
eral Procedures

1.
Open the engine compartment and fit paintwork protection
sheets. Open to the service position.
2. Carefully remove both engine covers, taking care not to
damage the plasti c fixings or the rubber inserts.

3. Di
sconnect the batt

4. Remove the cam cover from the 'A' bank and the 'B' bank;
including the purge valve, the on-plug ignition coils and the air
intake tube / air flow meter / air cleaner cover assembly. Refer
to Operations 12.29.43 and 12.29.44.
5. Rotate the crankshaft so that there are four valves which are
'off the cam' (cam lobes upperm ost), so that their clearance
may be measured.
6. Measure the gap on each of the four valves. Note which valve
has been measured, along with its relevant clearance.
7. Rotate the crankshaft a small am ount so that the next four
valves are 'off the cam'. Measure and note the clearances.
Re
peat this step
a further six times, until all valve
clearances have been measured and noted.
8. Refit the cam covers and associated components. Refer to
Operations 12.29.43 and 12.29.44.
9. Refit the engine covers.
10. Move the engine compartment cover from the service position
and connect the gas struts.
11. Remove the paint protection sheets and close the cover.
12. Connect the battery and fit the battery cover.
