Repair Procedures: Inspection
- Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block.
- Using a soft brush and solvent, thoroughly clean the cylinder block.
- Inspect the 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 :
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 x 100 mm (3.9370 in x 3.9370 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.
Cylinder bore diameter :
77.00 ~ 77.03 mm (3.0315 ~ 3.0327 in)
