Cylinder Block Repair

CAUTION: Do not attempt to repair cracks. Do not attempt to repair areas where temperature will exceed 260° C (500° F). Do not attempt to repair areas exposed to engine coolant or oil.





NOTE: 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 repaired area to blend with the general contour of the surface.
5. Paint the surface to match the rest of the cylinder block.
