1. Clean bore of valve guide (1) (never use a hard object).  

2. Inspect surface of bore for scores or signs of rubbing. 

 If damage to the surface is present, the valve 

guide must be replaced and the valve stem inspected for uneven areas. If the stem is damaged, the valve 
must be replaced together with the valve guide.

3. If it is possible to insert the side of the hole gauge (3) 

 marked with "+220" over its full length (5 mm) 

into the valve guide, it is then necessary to replace the valve guide. 

 Inspect bore of valve guide in 

longitudinal and transverse direction.
