1 Grind the valve seats (2) to the correct angle
specification, refer to 5 Specifications.
2 Using the correct angle specification, grind and relieve the valve seats (1) to correctly position the
valve seating surface (2) to the valve.
3 Using the correct angle specification, grind and undercut the valve seats (3) to narrow the valve seat
widths to the specifications, refer to 5 Specifications.
4 If the original valve is being used, grind the valve to the specifications, refer to 5 Specifications.
Measure the valve margin again after grinding, refer
to Valve Margin Measurement Procedure in this
Section. Replace the valve if the margin is out of
specification. New valves do not require grinding.
5 W hen grinding the valves and seats, grind off as little material as possible. Cutting valve seat results in
lowering the valve spring pressure.
6 Install the valve in the cylinder head.
Figure 6A1 – 296
CAUTION
If using refaced valves, lap the valves into the
seats with a fine grinding compound. The
refacing and reseating operations should
leave the refinished surfaces smooth and true
so that minimal lapping is required. Excessive
lapping will groove the valve face and prevent
a good seat when hot.
NOTE
• Clean any remaining lapping compound from
the valve and seat with solvent and
compressed air prior to final assembly.
• If fitting new valves, do not lap the valves
under any condition.
7 After obtaining the correct valve seat width in the cylinder head, measure the valve stem height, refer to Valve Stem Height Measurement Procedure in this Section.
8 If the valve stem height is acceptable, test the seats for concentricity, refer to Valve-to-Seat Concentricity Measurement Procedure in this Section.

Valve Stem Height Measurement Procedure
CAUTION
To determine the valve stem height
measurement, measure from the valve
spring seat to the valve spring retainer.
1 Install the valve into the valve guide.
2 Ensure the valve is seated to the valve seat.
3 Install the valve stem oil seal.
4 Install the valve spring retainer and valve stem keys.
5 Measure the distance (1) between the cylinder head to the bottom of the valve spring retainer, refer to 5
Specifications.
6 If the maximum height specification is exceeded, a new valve should be installed and the valve stem
height re-measured.
Figure 6A1 – 297
CAUTION
Do not grind the valve stem tip. The tip of the
valve is hardened and grinding the tip will
eliminate the hardened surface causing
premature wear and possible engine damage.
CAUTION
Do not use shims to adjust valve stem height.
The use of shims will cause the valve spring
to bottom out before the camshaft lobe is at
peak lift and engine damage could result.
7 If the valve stem height still exceeds the maximum height specification, the cylinder head must be replaced.
Assemble
1 Install the cylinder head coolant threaded plugs (1) and tighten to the correct torque specification.
Cylinder head threaded plug ..............................31.0 Nm
