Range Rover Heaven!


A busy day today at NZ Engines, on this mornings manifest;

1. 56 Reg Range Rover Sport 2.7 Diesel

2. 2006 Reg Range Rover Sport 4.2 Super Charged Petrol

3. 09 Reg Range Rover Vogue 3.6 Diesel

4. 07 Reg Discovery 2.7 Diesel

5. 2010 Reg Range Rover Sport 3.0 Diesel

6. 2006 Reg Range Rover Sport 3.6 Diesel



At NZ Engines the 3.6 TDV8 engines are completely rebuilt. After dismantling the engine from your Range Rover / Land Rover & removing the ancillary parts the engine is stripped to a single component level. After de-carbonating of all the components we assess them to establish the fault and then parts are replaced where faults discovered. We grind the crankshaft to required dimension if there is any problem with it. Connection rods are replaced, new cylinder liners fitted along with replacement pistons and piston rings. Engines are rebuilt with new seals and gaskets to reassure the highest quality and performance in the future.



The following damage is developed by still using the engine with bend con rods ( where the car started and engine is running). Commonly scoring of the cylinders will occur causing serious internal damage. Again it may be still ignored as the huge torque produced by the Land Rover / Range Rover TDV8 engine is moving the vehicle forward, however the damage to the engine will increase exponentially eventually causing the engine to seize and stop. At this point the engine will not start due to catastrophic internal damage. In the worst cases we have seen holes in the engine block / crankcase caused by the snapping con rod. Please do not ignore any signs that you may be experiencing this problem as it will cost more to repair an engine in this state, in some cases even rendering the engine beyond serviceability, which makes the repair bill even higher.


Tell-tale signs of a misfiring engine include a knocking noise, lack of power and smoke from exhaust. Usually the engine still works but every attempt to start the engine and drive the vehicle makes matters worse. It should be noted that as this is a V8 diesel engine with a lot of torque the very first symptoms are often ignored by the drivers because the engine may seem to start normally and the Range Rover.


The issue with the TDV8 engine's turbochargers is the fact is that the turbochargers are wearing and oil leakage occurs. Due to the massive amount of engine oil (nearly 9 litres in the oil sump of the engine ) it may be hard to spot that the oil level is decreasing. Less experienced professionals may not notice this and simply top-up the engines oil as there are no apparent leaks on a quick inspection. Officially in nature nothing is disappearing, however, in time, the engine oil level builds up in the inter-coolers. Once the oil level in inter-coolers is high enough sooner or later a surge of oil from the inter-coolers flows to the engine inlet manifold and then to the combustion chambers which leads directly to the cylinders. The pistons can not go up because of the oil inside of the engine combustion chamber which is not compressing ( the same as when water surge goes to the flooded engine causing water damage ). In this case it is very common for the connection rods to bend and even snap due to being under immense pressure attempting to turn the crankshaft and pistons.
