Test Sequence
-
Insert new valve into guide. The end of the valve stem 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 tilt clearance. Wear limit: max. 1.3 mm
-
If the tilt clearance exceeds the wear limit, the cylinder head must be replaced.
