Remove gasket material.
Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block.
Clean cylinder block
Using a soft brush and solvent, thoroughly clean the cylinder block.
Inspect top surface of cylinder block for flatness.
Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head gasket for warpage.
Flatness of cylinder block gasket surface
Standard:
Less than 0.05 mm (0.0020 in.) for total area
Less than 0.02 mm (0.0008 in.) for a section of 100 mm (3.9370 in.) X 100 mm (3.9370 in.)
Inspect the cylinder bore
Visually check the cylinder for vertical scratches.
If deep scratches are present, replace the cylinder block.
Inspect the cylinder bore diameter.
Using a cylinder bore gauge, measure the cylinder bore diameter at position in the thrust and axial direction.
Cylinder bore diameter:
81.00 ~ 81.03 mm (3.1890 ~ 3.1902 in.)
Measure position points (from the top of the cylinder block):
30 mm (1.1811 in.) / 60 mm (2.3622 in.) / 90 mm (3.5433 in.)
