2,2L 4-Cylinder 4-134 cui F-Head "Hurricane" Engine Parts for Jeep CJ3B

Why the 4-134 F-Head Engine in the Willys CJ3B Wears Out Over the Years.

The 4-134 Hurricane F-Head engine in the Willys CJ3B (1953–1964) marked a technical step up from the earlier L-Head unit: overhead intake valves in the cylinder head delivered more power from the same 2.2-liter displacement. After decades of service, however, this rugged engine shows typical wear. Head gaskets and valve cover gaskets harden and start leaking, piston rings lose tension and raise oil consumption, while rod and main bearings develop play from decades of friction. Valve guides and springs fatigue, and gaskets on the oil pan, intake manifold, and exhaust age and let oil or exhaust gases escape. Small parts like the alternator bracket or the PCV valve for crankcase ventilation wear out as well. Anyone keeping a CJ3B on the road or restoring it to original condition can't avoid regularly renewing these wear parts – it's the only way to preserve compression, oil control, and smooth running in this historic engine.

• Cylinder Head & Valvetrain: The head gasket seals the head to the block, while the camshaft gear, valve guides, valve springs, and valve cover gaskets keep valve timing precise.
• Crankshaft & Rod Bearings: From standard-size rod bearings to main bearings in several oversizes, plus the rear crankshaft seal and clutch pilot bearing.
• Pistons & Piston Rings: Piston rings and matching pistons in multiple oversizes for a proper engine rebuild.
• Gaskets & Sealant: The complete engine gasket set and the individual oil pan gasket complement manifold, exhaust, and fuel pump gaskets.
• Lubrication & Ventilation: The oil filter and PCV valve keep the oil circuit and crankcase ventilation working properly.
• Small Parts & Accessories: The alternator bracket and universal RTV sealant round out the engine rebuild.

Two US Brands for Your F-Head Engine.

Head gaskets, piston rings, rod bearings, engine gasket sets, and most other components come from Crown Automotive – one of the best-known names in American replacement parts manufacturing. Pistons, oversize piston rings, and the PCV valve are supplied by Omix, another US manufacturer with long experience in Jeep and Willys parts. Both brands stand for American engineering and precision reproductions in series quality.
