Nissan Dayz Replacement Engines
The Nissan Dayz has evolved through multiple generations with distinct engine families: K12B (2013-2017) with timing chain issues addressed in Service Bulletins, K14B (2017-2019) featuring larger displacement with head gasket concerns, and HR12DE (2019-present) incorporating newer fuel injection technology. All K12B engines suffer timing chain tensioner failures around 80,000 miles, while K14B units experience head gasket degradation after 70,000 miles. The HR12DE generation introduced oil pump reliability issues that affect all variants regardless of trim level, requiring comprehensive rebuilds with updated components.
Nissan Dayz Models & Engines Codes
Dayz engines span multiple generations with distinct families optimized for the compact kei-car platform. Each engine family shares common failure patterns across all Dayz variants.
- K12B: 1.2L petrol (2013-2017) - Timing chain tensioner (11340-6B000) failure across all variants
- K14B: 1.4L petrol (2017-2019) - Head gasket (11310-6B000) degradation in all models
- HR12DE: 1.2L petrol (2019-present) - Oil pump (15300-6B000) reliability issues across range
- K10B: 1.0L petrol (early variants) - Timing belt replacement (11310-7S000) critical maintenance
All Dayz engines require specific ECU programming and mounting configurations unique to the kei-car platform, ensuring proper integration with the vehicle's compact design and safety systems.
Buy Used and Second-Hand Nissan Dayz Engines
For Dayz owners, used engines carry high risk due to shared timing chain and gasket failure patterns. Reconditioned units with updated tensioners (11340-6B000) are essential for K12B engines. Remanufactured K14B engines with upgraded head gaskets (11310-6B000) are recommended regardless of variant.

⚙️ Nissan Dayz Engine Works: How Experts Rebuild Engines
When your engine fails, Nissan Dayz engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. Engine Removal & Assessment: Dayz engines are carefully removed using specialized equipment. Experts inspect the HR12DE/HR15DE block for cylinder wear, checking for the characteristic oil consumption issues common in E11 platform Dayz models. The timing chain tensioner (OEM 1104058F00) is examined for wear patterns specific to Dayz applications.
2. Disassembly & Component Inspection: Each Dayz engine is methodically disassembled with components catalogued. The cylinder head is checked for warping common in Dayz K10B/K15B variants. Oil control rings are measured for the specific wear patterns affecting Dayz engines after 60k miles. Specialized tools measure bearing clearances specific to Dayz engine architecture.
3. Block & Head Refurbishment: Dayz engine blocks undergo sonic testing to detect micro-cracks. Cylinder honing addresses the specific wear patterns found in Dayz applications using diamond-honing techniques. The cylinder head is resurfaced to Nissan specifications for E11 Dayz models. Valve stem seals are upgraded specifically for Dayz's oil consumption issues.
4. Component Replacement: New pistons, rings, and bearings are installed using Nissan-specified torque settings for Dayz engines. Timing chain components (OEM 1104058F00) are upgraded to address common failures. Oil pumps are replaced with enhanced units for Dayz's specific lubrication needs. Gaskets are installed using multi-layer steel technology for Dayz applications.
5. Assembly & Quality Control: Dayz engines are assembled using specialized torque sequences specific to E11 platform requirements. Each engine undergoes compression testing to meet Nissan specifications for Dayz variants. Oil pressure is verified at multiple RPM ranges. The engine is filled with Nissan-recommended fluids for optimal Dayz performance.
6. Testing & Final Preparation: Rebuilt Dayz engines run on dyno test beds simulating real-world conditions. Oil consumption is measured against Dayz specifications. Temperature cycling tests verify cooling system performance. Each Dayz engine receives a final inspection and documentation of all work performed specific to the E11 platform.
