Fig. 119: Identifying Basic Bore Diameter Of Valve Seat Ring In Cylinder Head - Shown On Exhaust 
Side
 

  

The overlap of the valve seat ring in the cylinder head is determined as follows: outside diameter of the valve 
seat ring (B) minus the basic bore diameter of the valve seat ring in the cylinder head (E).
