Remove the gasket material.
Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block.
Clean the cylinder block.
Using a soft brush and solvent, thoroughly clean the cylinder block.
Inspect the top surface of the 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 (0.002 in),
Less than 0.02 mm (0.0008 in) / 100 x 100 (3.937 x 3.937 in)
Inspect the cylinder bore.
Visually check the cylinder for vertical scratchs.
If deep scratchs 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.
Standard diameter :
72.00 ~ 72.03 mm (2.8346 ~ 2.8358 in)
Check the cylinder bore size code on the cylinder block.
Grade | Size code | Cylinder Bore inner Diameter |
a | A | 72.00 ~ 72.01 mm (2.8346 ~ 2.8350 in) |
b | B | 72.01 ~ 72.02 mm (2.8350 ~ 2.8354 in) |
c | C | 72.02 ~ 72.03 mm (2.8354 ~ 2.8358 in) |
