Nissan Cylinder Head RD28 semi assembly 171334
171334This Nissan RD28 cylinder head semi assembly 171334 fits engines that need a fresh top section after overheating, cracking, or long-term wear. The casting lines up neatly with factory mounting points, so workshops don’t struggle during installation. It works well for rebuilds where you want a clean base before fitting your internal parts. Many mechanics prefer this type of head because it avoids reworking old surfaces and helps the engine run smoother once everything sits in place.
This RD28 cylinder head semi assembly 171334 suits Nissan diesel engines that start showing the usual signs—loss of compression, rough start, or uneven idle after years of running. Most workshops pick a fresh head at this stage because repairing an old one often takes longer and still leaves doubts. This unit sits straight onto the block, and the machining gives enough accuracy for a clean fit without unnecessary adjustments.
Another thing worth noting is how the ports and chambers follow the RD28 layout. That helps the engine breathe the way it should once the rest of the parts are assembled. Mechanics often comment that a new head saves time because they don’t need to chase old cracks or warped areas. It also supports stable sealing when the gasket goes in place.
