General Procedures: Check
Using a suitable metallic straight edge and feeler gauge, measure the cylinder head face in the areas illustrated. Note the maximum value .
-
CAUTION: Machine the minimum thickness of material from the cylinder head to meet specification. If a selection of cylinder head gaskets are available, increase the thickness of the cylinder head gasket by one size.NOTE:
- Prior to having the cylinder head machined, prior approval is required by Jaguar or Land Rover engineering.
- If the cylinder head requires machining, this must be carried out by a local engineering company.
If the cylinder head exceeds the maximum value (0.2mm), the cylinder head must be machined.
