Restoring a Legend: Toyota 3B Cylinder Head Replacement

The Toyota 3B 3.4L diesel engine is the heart of some of the most iconic off-road vehicles in history, including the Land Cruiser BJ40, BJ60, and BJ70 series. Known for its low-end torque and simplicity, this 8-valve OHV engine is a favorite among restoration enthusiasts and commercial operators alike. However, decades of heat cycles can cause the original cast iron head to crack between the valve seats or around the pre-combustion chambers, leading to coolant loss and overheating.

Ruich Value offers a premium aftermarket cylinder head designed to breathe new life into these classic engines. Manufactured to replace OEM 11101-58010, our casting utilizes modern metallurgy to improve resistance to thermal shock while maintaining the exact dimensions of the original design. This ensures a perfect fit for the manifold, rocker assembly, and injectors, making it the ideal solution for restoring your vintage Toyota’s reliability.
