1. Apply a thin layer of Prussian Blue on the valve face. Then put
the valve on its seat to examine the contact.
2. If the valve is not fully around the seat or the contact is less than
70 % of the factory specification, correct the valve seat. See the
next section.
3. If the valve contact width cannot get the factory specification,
replace the valve or correct the contact of the valve seat.
