WSG-1068 GENERAL INFORMATION
Cylinder Block Repair - Cast Iron Porosity
Defects
CAUTION: Do not attempt to repair cracks, areas
where temperature will exceed 260°C (500°F) or
areas exposed to engine coolant or oil. These areas
will not repair and could cause future failure.
Repair porosity defects with an epoxy sealer meeting
Ford specification M3D35-A (E).
1. Clean the surface to be repaired to a bright, oil-
free metal surface.
2. Chamfer or undercut the repair area to a greater
depth than the rest of the cleaned surface. Solid
metal must surround the area to be repaired.
3. Apply the epoxy sealer and heat-cure with a
250- watt lamp placed 254 mm (10 inches) from
the repaired surface, or air dry for 10-12 hours at
a temperature above 10°C (50°F).
4. Sand or grind the repaired area to blend with the
general contour of the surface.
5. Paint the surface to match the rest of the
cylinder block.
Cylinder Block Core Plug Replacement
Special Tool(s)

bore is damaged, bore for the next oversize
plug.

in the flat located on the cup side of the plug.
3. Coat the cylinder block core plug and bore lightly
