The Nissan TD42 engine cylinder head (OEM: 11041-06J00) is a heavy-duty cast iron component engineered for Nissan Patrol Y60/Y61 (GQ/GU), Civilian Bus W40, and TCM FD40/FD50 industrial forklifts. It features upgraded metallurgy to effectively resolve chronic thermal cracking at cylinders 5 and 6, and prevents pre-chamber drops under heavy loads. View full Nissan Cylinder Head catalog. Factory direct supply available for global wholesale export.
The Nissan TD42 4.2L inline-six diesel engine is legendary for its bulletproof bottom end, powering iconic off-roaders like the Nissan Patrol Y60 (GQ) and heavy-duty industrial equipment like TCM 4-ton to 5-ton forklifts. However, the immense thermal load of this long 6-cylinder block eventually exposes structural weaknesses in the factory cylinder head.
Engine rebuilders consistently face two major failure modes: restricted coolant flow at the rear of the block causes severe thermal fatigue, leading to cracking between the valves on cylinders #5 and #6. Additionally, extreme temperature fluctuations often cause the pre-combustion (swirl) chambers to loosen and drop into the cylinders. Ruich Value’s replacement TD42 cylinder head tackles these exact issues. Cast from an advanced, high-density iron alloy, our head provides exceptional thermal shock resistance and dimensionally stable pre-chamber seating, ensuring your commercial fleet or heavy-duty 4×4 stays operational.

Because the TD42 is a long inline-six engine, coolant flow reaches maximum temperature by the time it reaches the rear cylinders (#5 and #6). When operating under heavy loads—such as towing with a Patrol Y61 or lifting with a TCM FD50 forklift—this thermal stress causes micro-cracking between the exhaust and intake valves. Our replacement head utilizes upgraded high-density cast iron and optimized water jackets to significantly improve heat dissipation at the rear of the block.
Yes. The OEM part number 11041-06J00 (cross-reference AMC 908 505) is the standardized naturally aspirated indirect-injection cylinder head used across the 4.2L TD42 platform. It perfectly matches the block configurations for Nissan Patrol Y60 (GQ), Civilian W40 buses, and heavy-duty TCM forklifts. For factory turbocharged variants (TD42T), please consult our technical team for specific valve material requirements.
We strongly recommend it. The TD42 is notorious for dropping pre-combustion chambers into the cylinder after high-mileage thermal cycling. When installing this bare cylinder head, transferring old, heat-fatigued pre-chambers poses a massive risk of catastrophic engine failure. Always install new pre-combustion chambers, premium head bolts, and a high-quality multi-layer steel (MLS) head gasket.
