Checking procedure
Insert the new valve into the guide sleeve. The end of the valve stem must be covered by the guide bushing. Due to the different stem diameter, use the inlet valve only in the inlet valve guide and the exhaust valve in the exhaust valve bush respectively.
Determine valve play (pic. 2.84).
Wear limit: 0.8 mm.
If the rocking play is exceeded, replace the cylinder head.
