the engine has been equipped with a new valve timing system spring kit.
The procedure for installing the new springs is the same as the procedure described for the previous
springs.
CAUTION
THE NEW VALVE KIT MAY ALSO BE INSTALLED ON ALL PRIOR ENGINES.
CAUTION
THE NEW SPRINGS CANNOT BE INSTALLED TOGETHER WITH OLD SPRINGS. WHEN USING
THE NEW SPRINGS, THE SPRINGS ON ALL SIXTEEN VALVES MUST BE REPLACED.
As before, the intake valves are fitted with two
springs while the exhaust valves are fitted with a
single spring.
The new intake valve springs are marked blue and
the new exhaust springs are marked red.
The old intake valve springs are marked blue and
the old exhaust springs are marked yellow.
The new springs are identifiable as they are
marked differently than the old springs; on the new
springs, the first turn is coloured completely
whereas the old springs are marked with lines on
the side.
CAUTION
WHEN REPLACING ALL THE SPRINGS, IT IS ALSO NEC-
ESSARY TO REPLACE ALL THE LOWER CAPS OF THE
INTAKE VALVES. THE NEW CAPS CAN BE DISTINGUISH-
ED FROM THE OLD CAPS AS THEY HAVE A CIRCULAR
GROOVE WHICH IS ABSENT ON THE OLD VALVES.
WHILE THE NEW UPPER CAPS OF THE INTAKE VALVES
ALSO HAVE A GROOVE, THEY ARE INTERCHANGEABLE
WITH THE OLD CAPS. THE CAPS OF THE EXHAUST
VALVES ARE THE SAME AS BEFORE.
