Why Rebuild a Nissan Engine?
Cost Savings
You’ll save a couple of grand on an rebuilt engine versus a replacement engine. When rebuilding, you get to recover the engine block and other heavy-duty components and just replace the worn-out pieces.
Extended Vehicle Life
Having a good transmission and chassis on your Nissan, with a rebuilt engine, you can enjoy years of hassle-free service.
Environmental Benefits
Rebuilding saves material already created, and waste and the expense of engine manufacturing to the environment are avoided.
Warranty Backed
A high-quality rebuilt engine is equal to — and usually superior to — the original factory engine, especially when combined with performance hardware.
Step-by-Step Engine Rebuilding Process of a Nissan Engine
An engine rebuild is a highly technical process that requires technical skill, specialized tools, and quality parts. This is how it’s done:
1. Engine Removal
The engine is removed from the vehicle and readied for teardown.
2. Complete Disassembly
All of it is dismantled — pistons, crankshaft, cylinder head, valves, etc. Components are sorted by type: reusable, repairable, or replaceable.
3. Cleaning & Inspection
Engine block and other parts salvageable are cleaned using industrial solvents and hot tanks. Parts are inspected for cracks, wear, and damage.
4. Machining & Repair
- Cylinder block: Bored, honed, or resurfaced to receive proper piston fit.
- Crankshaft: Ground and polished.
- Cylinder head: Leaks pressure-tested and resurfaced.
- Valves: Resurfaced or replaced to seal properly.
5. Replacement of Worn Part
Wear parts essential to the engine are replaced with new or OEM-quality components:
- Pistons and piston rings
- Bearings
- Timing belts or chains
- Gaskets and seals
- Oil pump
- Water pump
6. Correctness of Reassembly
All of these components are reassembled to OEM specifications in terms of torque settings.
7. Testing & Quality Assurance
The remanufactured engine is even performance tested, e.g., compression test, leak test, and even a complete dyno test, to ensure that it meets Nissan standards.
