Thanks to Muggy Weld 77 cast iron welding rod, engine block welding has never been easier.Ĭase in point: This diesel Yanmar cast iron engine had a large hole in the block, caused by a thrown push rod. ![]() Historically, mechanics would either replace the engine block or disassemble the engine to make the repair–both costly solutions. Engine block welding can be a challenging task, due to the temperamental nature of cast iron.
