Cylinder Head Assembly
Cylinder HeadDeck Flatness Inspection
If the warpage is less than 0.05 mm (0.002 in), the cylinder head deck surface does not require resurfacing.
If the warpage is between 0.05-0.20 mm (0.002-0.008 in) or any imperfections or scratches that could inhibit proper cylinder head gasket sealing are present, the cylinder head deck surface requires resurfacing.
If resurfacing is required the maximum amount that can be removed is 0.25 mm (0.010 in).
If the cylinder head deck surface requires more than 0.25 mm (0.010 in) material removal the head must be replaced.
