LR005521 LR005522 Land Rover 4.0L V6 Engine Overhaul Kit OEM
1. Product Attributes
| Category | Details |
|---|---|
| Compatibility | Land Rover 4.0L V6 petrol engines (e.g., Thor engine in Discovery II/Range Rover early 2000s). |
| Kit Contents | - Gaskets (valve cover, oil pan, intake/exhaust manifold) - Seals (crankshaft front/rear, valve stem) - Piston rings - Main/connecting rod bearings - Timing chain tensioner (optional in some kits) - Bolts (critical fasteners) - Head gasket (may vary by kit). |
| Material | - Bearings: High-tin aluminum alloy/copper-lead with coatings - Seals: Fluoroelastomer (FKM) or PTFE - Gaskets: Multi-layer steel (MLS) or composite fiber. |
| OEM Standards | Manufactured to original Land Rover specifications for fitment and durability. |
| Purpose | - Full engine rebuild - Repair oil leaks, low compression, or bearing wear - Preventive maintenance for high-mileage engines. |
| Key Benefits | - Restores factory performance - Reduces friction and wear - Ensures proper sealing and lubrication. |
| Installation | Requires professional tools (torque wrench, ring compressor) and machining (if block/head resurfacing needed). |
| Quality Control | - Pressure-tested gaskets - Dimensional precision (±0.001" for bearings) - Fatigue-resistant materials. |
| Lifespan | Matches OEM service life (typically 100,000+ miles with proper installation). |
| Notes | Avoid non-OEM kits for critical components (e.g., head gaskets) to prevent premature failure. |
2. Applications
-
Primary Use Cases:
-
Engine Overhaul: Full repair for issues like oil burning, abnormal noises, or low compression.
-
Preventive Maintenance: Replacement of wear-prone parts during high-mileage engine disassembly.
-
Engine Rebuilding: Restoration of old or damaged engines to factory performance.
-
-
Compatible Engines: Primarily fits Land Rover 4.0L V6 petrol engines (e.g., the Thor engine, used in early 2000s Discovery II or Range Rover models).
3. Working Principles
-
Functional Synergy:
-
Sealing System: Gaskets/seals prevent oil leaks and maintain lubrication pressure.
-
Friction Control: Bearings and piston rings optimize friction, reducing wear.
-
Thermal Management: Head gaskets ensure proper sealing, preventing coolant/combustion gas leaks.
-
-
Performance Restoration: Replacing worn components restores compression ratio, lubrication efficiency, and other critical parameters to factory specs.
4. Manufacturing Process
OEM Production Steps:
-
-
Material Selection:
-
Bearings: High-tin aluminum alloy or copper-lead layers with coatings.
-
Gaskets: Multi-layer steel (head gaskets) or composite materials (manifold gaskets).
-
-
Precision Machining:
-
CNC machining for bearing tolerances (±0.001 inches).
-
Laser-cut gaskets for exact sealing profiles.
-
-
Surface Treatments:
-
Piston rings with chrome or molybdenum coatings for reduced friction.
-
PTFE-coated oil seal lips for enhanced sealing.
-
-
Quality Control:
-
Pressure testing (gaskets), fatigue testing (bearings), full dimensional inspection.
-
-
5. Key Considerations
-
Installation Requirements: Requires professional tools (torque wrench, ring compressor) and techniques (e.g., bearing clearance measurement).
-
Recommended Additional Steps: Inspect camshafts, cylinder block wear; machine block/crankshaft if necessary.
-
Non-OEM Risks: Aftermarket parts may fail prematurely due to inferior materials (e.g., gasket deformation causing leaks).
