A loss of coolant or problems at the cooling circuit or cylinder head gasket can result in overheating and thus in a distortion and modification of the microstructure of the cylinder head.
Machining only then produces a tight bond of cylinder head - cylinder head gasket - crankcase if a certain minimum hardness is achieved.
1 Smooth the surfaces to be inspected with a fine emery stroke in one direction.
2 Inspect hardness at the two points (arrows) in the area of the blowby traces of the cylinder head gasket.
If the hardness is not achieved, replace cylinder head.
