How to Repair a Cracked Cylinder Block?
1 Answers
First, use coarse sandpaper to remove the rust around the crack in the cylinder block. When sanding to a certain extent, you can locate the end of the crack. Proceed directly with welding a repair plate. Pay attention to any warping at the welding site. If there is any, be sure to hammer the welded area while it's still hot to avoid leaving any welding slag. After the repair, place an asbestos gasket between the repair plate and the cylinder block (or cylinder head), and then apply a layer of lubricating oil on both sides.
