Wartime Flathead Engineering Rebuild: Overhauling Your Willys MB 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. It powered the Willys MB across every front of World War II and served as the mechanical blueprint for the entire Jeep lineage. Famous for its durability, this vintage flathead block requires high-precision mechanical attention after decades of convoy storage or historic driving events. Exhausted valve springs, pitted bearing shells, or messy oil leaks at the rear main seal 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 battlefield reliability back to your four-cylinder block.


Quality authentic Engineering for Vintage Upgrades: Crown, Omix & MD Juan.

For internal mechanical block restorations, we stock high-durability crankshaft main bearings available in 0.010" and 0.040" oversizes to match machined crank journals perfectly. Completely refresh your rotating mass using premium standard-size rod bearings, heavy-duty bolts, and classic clutch pilot bearings. We guarantee an airtight barrier against compression and fluid loss with professional-grade components from Crown Automotive, including factory-spec cylinder head gaskets, high-tensile head studs, oil pan gaskets, crankshaft oil seals, and timing gear cover gaskets.
Restore your L-head engine's valvetrain timing and breathing seamlessly with new replacement intake valves, heavy-wall valve springs, timing chains, and camshaft gears from Omix and Crown. Safeguard your peripheral mounting faces with precise exhaust gaskets, water pump backing seals, fuel pump seals, and the critical 3-piece manifold gasket set from Crown. Our comprehensive range is finalized by functional details like alternator bracket bolts, Standard PCV valves to regulate crankcase pressure, and the iconic official reproduction carburetor air horn tubes from MD Juan and Omix to preserve that showroom military look under your hood.
