Test Sequence
-- Insert the valve into the guide. The valve stem tip must be flush with the guide. Due to the slight difference in stem dimensions, ensure that only an intake valve is used in the intake guide and an exhaust valve in the exhaust guide.
-- Determine the tip clearance.
Wear Limit
| Intake Valve Guide | Exhaust Valve Guide |
|---|---|
| 0.80 mm | 0.80 mm |
NOTE:
If the wear limit is exceeded, measure again using new valves. If the wear limit is still exceeded, replace the cylinder head.
If the valve is to be replaced as part of a repair, use a new valve for the calculation.
