Nissan Cylinder Head assembly ZD30 non common rail 908506 171312

This cylinder head assembly for the Nissan ZD30 non-common-rail engine 171313 is built for vehicles that go through long hours of towing, off-road use, or steady commercial running. Many mechanics come across ZD30 heads that warp or crack near the hot zones, especially after overheating. This replacement sits in the same position as the factory unit and gives you a fresh top-end base to work with.

The head matches the ZD30 port shape and bolt layout, so the manifolds line up without trouble. Most technicians like that the sealing surface holds straight during fitting, which helps when setting the gasket in place. Another thing worth noting—shops often choose a full assembly like this when the original head has too much damage to reface.

Key Points for Buyers

• Fits Nissan ZD30 non-common-rail engines used in many work and utility vehicles
• Casting and machining follow the original layout, so parts sit as they should
• Works well for engines with cracked chambers, overheating marks, or compression loss
• Supports a clean rebuild and helps restore smoother running
• Suitable for workshops handling regular ZD30 repairs and fleet maintenance

In most cases, fitting a new head saves time compared to repairing a heavily damaged one. Once installed, the engine usually settles into a more stable idle and responds better under load.

Acme Impex checks each cylinder head for casting quality and consistent machining before dispatch. That means you receive a part that sits straight, holds its surfaces well, and supports a proper top-end rebuild. If your ZD30 needs a fresh start, this assembly gives you a practical and workshop-ready option to get the vehicle back on the road.
