How to Repair Cracks in the Engine Block?
1 Answers
First, use coarse sandpaper to remove the rust around the crack in the engine block. When sanding to a certain extent, the terminal of the crack can be located. Then, proceed directly with welding a repair plate. However, be cautious of warping at the welded area. If warping occurs, it must be hammered while still hot. After the repair, place an asbestos gasket between the repair plate and the engine block (or cylinder head), and then apply a layer of lubricating oil on both sides.
