Engine / Cylinder head
Re-machining the valve seats
Observe specified seat angle.
Note:
When re-machining the valve seat inserts, only
the minimum of material should be removed.
Reference value will be value of valve recess.
If the cylinder head faces are re-machined (max.1
mm (.039")), it is necessary also to re-machine the
inserts in order to obtain the correct valve recess:
When fitting new valves and inserts, machine out
cylinder head to amount relative to the skimming
of the cylinder head face.
Having skimmed the cylinder head face and
machined the valve seat insert, the theoretical
valve seat may have become too deep in the
cylinder head or the seat surface may be too wide.
In this event the valve seat insert must be
replaced.
Always observe the correct value for valve recess.
