Cylinder Block

WARNING: This page is about a different car, the 2007 Kia Sedona and 2006 Kia Sedona. However, it is still accessible from the selected car via links, so may be relevant.

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.), Less than 0.02 mm (0.0008 in.) /150 x 150

Inspect cylinder bore diameter
Visually check the cylinder for vertical scratches.

If deep scratches are present, replace the cylinder block.
Inspect cylinder bore diameter
Using a cylinder bore gauge, measure the cylinder bore diameter at position in the thrust and axial directions.

Standard diameter

96.00-96.03 mm (3.7795-3.7807 in.)
