Hyundai D4EB Cylinder Head assembly (without cam and rockers) 171920-1
171920-1This Hyundai D4EB cylinder head assembly 171920-1 suits engines that start showing cracks, overheating marks, or uneven compression. It sits in place like the original and lines up cleanly with the block. Workshops often pick this type of head when they want a fresh base for a rebuild without dealing with worn surfaces. It supports smooth fitting of valves and timing parts later on. A good choice if you’re trying to bring the D4EB engine back to stable running.
The Hyundai D4EB cylinder head assembly 171920-1 works well for engines that reach a point where repairs don’t hold anymore. Most mechanics notice the first signs — rough idle, coolant pushing out, or exhaust gases slipping into the cooling system. When that happens, a clean replacement head usually makes more sense than trying to patch the old one.
This head follows the D4EB layout, so all ports, bolt positions, and coolant passages sit exactly where they should. It makes the install straightforward. You don’t need to fight alignment or reshape anything. In most cases, it drops in and matches the engine’s timing and intake setup without fuss.
Another thing worth noting is the casting. It holds its shape well and gives technicians a solid surface for valve seating and gasket fitting. Shops that rebuild multiple Hyundai diesel engines often keep a similar head on the shelf because it saves time and cuts down on comebacks caused by cracked castings.
