Watch This Jeep Engine Get Welded After a Piston Blows Through the Block!

Mike Timm welded his 2004 Jeep Wrangler engine block, which had a piston skirt blow a hole in the side of the motor. After being repeatedly told "cast iron welding is impossible," Mike purchased Muggy Weld 77 electrodes and decided to attempt the job himself. Mike could repair the block using a mild steel patch and his old Lincoln welder. Try the 77 electrodes on injection port cracks on 2002-2004 4020 Branson tractor cylinder heads. #JeepWranglerRepair #JeepEngineBlockWelding #PistonSkirtHoleRepair #DIYCastIronWelding #MuggyWeldIt Product: 77 Electrode 🔔 If you found this video helpful, subscribe for more practical metal repair tutorials.
