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.


Authentic Engineering for Vintage Upgrades: Crown, Omix & MD Juan Excellence.

For internal mechanical block restorations, we stock high-durability replacement pistons available in 0.040" oversize from Omix, paired with 0.040" piston ring sets from Crown and 0.060" sets from Omix. Re-align your crankshaft journals perfectly with our selection of main bearings available in 0.010" and 0.040" oversizes, complemented by connecting rod bearings stretching across standard size, 0.040", 0.050", and 0.060" tolerances by Crown. Rebuild your internal valvetrain seamlessly using Crown intake valves, valve springs, dedicated intake and exhaust valve guides, Crown camshaft timing gears, and fresh clutch pilot bearings.
We guarantee an airtight barrier against compression and fluid loss with premium components from Crown Automotive, including master engine gasket sets, factory-spec head gaskets, high-tensile cylinder head studs, timing cover gaskets, crankshaft seals, and side valve cover seals. To preserve that showroom accuracy, we supply the traditional cork oil pan gasket from Crown, perfectly paired with heavy-duty RTV silicone sealants. Optimize your engine's internal breathing path using the Omix intake manifold or the iconic official reproduction carburetor air horn tube from MD Juan. Our range is finalized by functional details like mechanical fuel pump seals, exhaust-to-downpipe gaskets, water pump backing seals, PCV valves, alternator bracket bolts, oil filter housing brackets, and factory-style air cleaner wing screws from Omix.
