CAUTION: Incorrect fitment of the valve
~
stem oil seals could lead to high oil
consumption and blue smoke emissions from the
exhaust system. Do not use excessive force in
fitting the seal as this may break the seal ring.
4. Install the valve springs over the valve stem
ensuring that the close wound coil end faces
towards the cylinder head.
5. Compress the valve spring ensuring that the spring
is compressed squarely to prevent damage to the
valve stem and cylinder head.
6. Fit the valve collets ensuring correct collet location
in the spring cap and valve as the spring
compressor is released.
A
CAUTION: Always check for correct
~
location of the valve collets during and
after assembly. If not fitted correctly, the collets
may become dislodged when the engine is running
allowing the valves to contact the pistons. Any
such valve to piston contact
will
cause severe
engine damage.
