Post-War Flathead Engineering Rebuild: Overhauling Your Jeep CJ3A 2.2L Go-Devil Engine.
The 2.2-liter four-cylinder side-valve engine (134 cui L-head), famously known as the „Go-Devil“, is an absolute milestone of automotive history, powering the Jeep CJ3A through intense agricultural, industrial, and civilian post-war utility. Famous for its durability, this vintage flathead block requires high-precision mechanical attention after decades of heavy use or prolonged storage. Exhausted valve setups, pitted bearing shells, or messy oil leaks at the crankshaft seals and head gasket are common milestones during any authentic restoration. Our specialized online inventory features professional-grade hardware to restore factory compression, oil tightness, and post-war reliability back to your four-cylinder flatfender block.
