dure. 

• Apply prussian blue (or white lead) onto contacting surface of valve seat to check the condition of the valve

contact on the surface.

• Check if the contact area band is continuous all around the circum-

ference.

• If not, grind to adjust valve fitting and check again. If the contacting

surface still has NG conditions even after the re-check, replace
