3. Remove inlet and exhaust camshafts.
CAUTION: Suitably identify each camshaft
to its fitted position, do not interchange
camshafts.
4. Remove and discard 2 oil seals from each
camshaft.
5. Using a stick magnet, remove 16 tappets.
CAUTION: Store tappets in their fitted
order and invert to prevent oil loss.
Camshafts - inspection
NOTE: Carry out camshaft inspection after
removal of valves and springs.
1. Clean camshafts and bearing journals in
camshaft carriers and cylinder head.
2. Inspect cams and camshaft bearing journals,
replace camshaft(s) if scoring, pitting or
excessive wear is evident.
3. Inspect bearing journals in cylinder head and
camshaft carriers, replace components if
scoring, pitting or excessive wear is evident.
4. Remove all traces of oil from bearing journals
in cylinder head, camshaft carriers and
camshafts.
5. Position camshafts on cylinder head.
6. Position a piece of Plastigage across each
camshaft bearing journal.
7. Fit camshaft carriers, fit securing bolts and
working from the centre outwards,
progressively tighten bolts to 25 Nm. Do not
rotate camshafts.
8. Remove camshaft carrier securing bolts,
remove carriers.
9. Measure widest portion of Plastigage on each
bearing journal and from dimensions obtained,
calculate camshaft bearing clearance.
Camshaft bearing clearance = 0.060 to 0.094
mm
Service limit = 0.15 mm

10. If bearing clearance is excessive, fit new
camshaft(s) and repeat check; if excessive
clearances still exist, renew cylinder head and
camshaft carriers.
11. Remove all traces of Plastigage using an oily
rag.
12. Transfer drive pins from old camshafts to new
with split fitted towards centre of camshaft.
Valves and springs - remove
1. Using a hollow drift, tap each valve spring cap
to free collets.
2. Position cylinder head on its exhaust manifold
face.
3. Using tool LRT-12-034 and adaptor
LRT-12-034/1, compress inlet valve spring.
4. Remove 2 collets using a magnet.
5. Release tool LRT-12-034 and remove valve,

valves.
CAUTION: Keep valves, springs, caps and
collets in fitted order.
8. Position cylinder head on its inlet manifold
face.
9. Remove exhaust valves and valve stem oil
seals using the above procedures.
Cylinder head - inspection
1. Clean all traces of gasket material from
cylinder head using suitable gasket removal
spray and a plastic scraper. Remove sealant
using suitable solvent.
CAUTION: Take great care not to damage
gasket face of head. If locating dowels
have been removed with cylinder head,
they must be refitted in cylinder block.
2. Thoroughly clean cylinder head, blow out
oilways and coolant passages.
3. Ensure camshaft carrier locating dowels are
fitted.
4. Check cylinder head for damage, cracks or
burning.
5. Check condition of 10 core plugs, renew any
plug showing signs of cracks, corrosion or
weeping, seal new plugs using Loctite 601.
6. Check cylinder head face for warping.
Longitudinal warp = 0.1 mm max.
Transverse warp = 0.1 mm max.
Diagonal warp = 0.1 mm max.
CAUTION: If warping exceeds the figures
given, a new cylinder head must be fitted.
Cylinder heads must not be refaced.
7. Check cylinder head height measured from
face of head to camshaft carrier face.
Cylinder head height = 135.0 to 135.1 mm

8. Check gasket face of cylinder head for
scratches or indentations paying particular
attention to the shaded areas in the above
illustration.
Cylinder head gasket selection
1. If scratches or indentations exist, fit cylinder
head gasket coated with black sealant.
NOTE: This gasket was fitted as standard
to all engines up to engine no. 128817. It
will be necessary to fit the oil restrictor in
the cylinder block.
2. If no scratches or indentations exist, fit cylinder
head gasket which is of multi-layer steel
construction.
NOTE: This gasket is fitted as standard to
all engines from engine no. 128817 and
may be fitted to all engines prior to this
number provided the above conditions are met.
It will be necessary to remove the oil restrictor -
if fitted from the cylinder block.
