by measuring from valve tip to spring seat . Remove valve from cylinder head and grind valve tip until
within specifications. Check valve tip for scoring. The tip chamfer should be reground (if necessary) to
prevent seal damage when the valve is installed.
6. Check the valve spring installed height after refacing the valve and seat .
If valves and/or seats are reground, measure the installed height of springs , make sure measurements are
taken from top of spring seat to the bottom surface of spring retainer. If height is greater than
specifications, install a 0.794 mm (0.0312 in.) spacer in head counterbore to bring spring height back
within specifications.
